Psychosocial Well-Being and Quality of Life in Uveitis: A Review

PURPOSE

As a potentially sight-threatening disease with ocular, systemic, and treatment-related complications, uveitis diminishes quality of life (QOL) and affects psychosocial well-being. This review summarizes the existing tools for evaluating psychosocial well-being and/or QOL in patients with uveitis, explores the biological and non-biological factors affecting psychosocial well-being and/or QOL, and proposes future directions for incorporating these tools into clinical practice.

METHODS

A systematic search of the MEDLINE, Embase, and Cochrane databases from inception to June 8, 2022 was conducted, screening for articles focused on psychosocial well-being and/or QOL in patients with uveitis. Both quantitative and qualitative analyses were performed.

RESULTS

In uveitis research, the most frequently studied patient-reported outcome measures were vision-related QOL (e.g. Visual Function Questionnaire [VFQ-25]) and health-related QOL (e.g. Short Form Survey [SF-36]), followed by mental health indicators including depression and anxiety. Instruments have also been developed specific to the pediatric population (e.g. Effects of Youngsters' Eyesight on Quality of Life [EYE-Q]). Generally, studies report worse psychosocial outcomes and QOL in patients with uveitis compared to the general population. Contributory factors include both clinical (e.g. visual impairment, ocular comorbidities) and patient-related (e.g. older age, female sex) factors.

CONCLUSION

Given the heterogeneity of instruments used, it is worth considering standardization across large uveitis studies and trials. Beyond research, given the biopsychosocial effects on patients with uveitis, there are benefits to incorporating QOL and psychosocial assessments into clinical practice. Simplification of questionnaires into abridged forms, focusing on the most clinically relevant aspects of patient care, may be considered.

What do adults with visual impairment mean by well-being? Identifying the building blocks of well-being in the context of visual impairment

Background

Well-being has become a key outcome of health and support services for adults with visual impairment (V.I.). However, there is a lack of consensus on how well-being is conceptualized and assessed in V.I. research, if it is defined at all. A shared understanding of what well-being means in the context of adult V.I. is essential to enable comparison of findings across studies and collaboration between support organizations.

Methods

This article reports findings from a series of four online focus groups with adults with V.I. and one with practitioners working in the field of adult V.I. The focus groups explored what participants meant by well-being and which factors impacted their well-being. A total of 17 adults with V.I. and five practitioners took part. A list of all components of well-being, factors that impact well-being, and items in the protective buffer that may mitigate the impact of factors on well-being were extracted from the data.

Results

Despite the noted difficulty in defining well-being and disagreement around the extent to which well-being was universal or individual, a preliminary model of well-being emerged from the focus group discussions. The core of well-being reflects an overall feeling of contentment arising from a positive evaluation of how one is feeling, how one is feeling within oneself, and how one is feeling about one's life. Factors relating to balance/equilibrium, health, mood, other people, the self, and a sense of security and purpose can positively or negatively impact well-being. This impact may be mitigated by a protective buffer consisting of one's mood, mindset, ability to cope, resilience, and acceptance. Many items were discussed in multiple roles, e.g., as a component of well-being or factor.

Conclusion

This research took a bottom-up approach to explore what well-being means in the context of adult V.I. The role of certain items and the structure of the proposed model of well-being will need to be confirmed in future research with stakeholders across the V.I. sector.

Understanding how traumatic brain injury-related changes in fluid biomarkers affect quality of life outcomes in veterans: a prospective observational trial protocol (UNTANGLE)

INTRODUCTION

Traumatic brain injury (TBI) is a major cause of disability, with annual global incidence estimated as 69 million people. Survivors can experience long-term visual changes, altered mental state, neurological deficits and long-term effects that may be associated with mental illness. TBI is prevalent in military personnel due to gunshot wounds, and blast injury. This study aims to evaluate the relationship between evolving visual, biochemical and mental health changes in both military veterans and civilians, suffering from TBI, and detect preliminary indicators of prognosis for TBI recovery, and quality-of-life outcomes.

METHODS AND ANALYSIS

UNTANGLE is a 24-month prospective observational pilot study recruiting three patient groups: civilians with acute moderate-severe TBI, military veterans with diagnosis of a previous TBI and a control group of civilians or veterans with no history of a previous TBI. Patients will undergo visual, biochemical and mental health assessments, as well as patient-reported quality of life outcome measures over the course of a 1-year follow-up period.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Health Research Authority and Health and Care Research Wales with a REC reference number of 23/NW/0203. The results of the study will be presented at scientific meetings and published in peer-reviewed journals, including both civilian and military-related publications. We will also present our findings at national and international meetings of learnt neuroscience and neuropsychiatry and military societies. We anticipate that our pilot study will inform a larger study on the long-term outcomes of TBI and quality of life, specific to military veterans, such that potential interventions may be accessed as quickly as possible.

Association Between Multimorbidity and Presence of Diagnosed Vision Problems Among the Middle-Aged and Older Population in India

PURPOSE

The aim of the study was to estimate the prevalence of diagnosed vision problems and to examine the association of single and multiple chronic conditions with vision problems among middle-aged and older adults in India.

METHODS

The study utilized data from the Longitudinal Ageing Study in India (LASI) Wave 1, (2017-18). Descriptive statistics along with bivariate and multivariable analyses were conducted to achieve the study objectives.

RESULTS

The prevalence of diagnosed vision problems in the sampled population was 48.2%. The older adults (60+ years) (55.3%) had shown a greater prevalence of vision problems than the middle-aged individuals (41%). Among chronic conditions, hypertension, diabetes, chronic lung diseases, chronic heart diseases, bone related diseases, psychiatric disorders, and high cholesterol were significantly associated with vision problems in the case of both middle-aged and older adults. Furthermore, odds of experiencing vision problems according to the presence of multimorbidity were higher in the middle-aged population [adjusted odds ratio (AOR) = 1.986; confidence interval (CI):1.855-2.126] than in the older population [AOR = 1.746; CI:1.644-1.854].

CONCLUSIONS

Middle-aged and older adults with chronic illnesses and multimorbidity were at greater risk of vision problems. Due to the high prevalence of vision problem, interventions aimed at prevention or early detection are warranted.

Interaction between visual impairment and genetic risk of dementia and psychosis in older adults

BACKGROUND

Visual impairment (VI) is associated with dementia and other neuropsychiatric outcomes, but previous studies have not considered genetic sources of confounding or effect modification.

METHODS

We analysed data from the Health and Retirement Study, an ongoing nationally representative survey of older US adults, a subset of whom underwent genetic testing from 2006 to 2012 (n = 13 465). Using discrete time proportional hazards models and generalised estimating equations, we measured the association between VI and dementia, depression and hallucinations adjusting for demographics and comorbidities, ancestry-specific principal components and polygenic risk scores (PRS) for Alzheimer's disease, major depressive disorder or schizophrenia. Effect modification was assessed using VI-PRS interaction terms and stratified analyses.

RESULTS

VI was associated with dementia, depression and hallucinations after adjusting polygenic risk and other confounders. There was no VI-PRS interaction for dementia or depression. However, the association between VI and hallucinations varied by genetic risk of schizophrenia. Within the bottom four quintiles of schizophrenia PRS, VI was not associated with hallucinations among White (OR 1.16, 95% CI: 0.87-1.55) or Black participants (OR 0.96, 95% CI: 0.49-1.89). In contrast, VI was strongly associated with hallucinations among White (OR 2.08, 95% CI: 1.17-3.71) and Black (OR 10.63, 95% CI: 1.74-65.03) participants in the top quintile of schizophrenia PRS.

CONCLUSIONS

The association between VI and neuropsychiatric outcomes is not explained by shared genetic risk factors, and there is a significant interaction between VI and polygenic risk of hallucinations in older adults.

Influenza epidemiology and treatment in people with a visual disability: A retrospective cohort study

BACKGROUND

Visual disabilities (VD) are expected to rise with an aging population. Persons with VD experience a higher prevalence of chronic and acute diseases. Despite the significance of influenza to this population, there is limited data comparing influenza care disparities between those with VD and those without.

OBJECTIVE

The study aimed to determine the influenza burden and associated healthcare utilization in individuals with VD compared to those without disabilities.

METHODS

A retrospective cohort study was conducted using the Korean National Health Information Database, encompassing three influenza seasons (2011-2012 to 2013-2014). The influenza incidence and incidence rate ratio (IRR) was calculated. Adjusted IRRs were calculated using a zero-inflated Poisson model. We assessed the risk of admissions and 30-day post-influenza mortality, employing logistic regression or survival analysis.

RESULTS

A total of 504,374 patients (252,964 patients with VD and 251,410 controls) were followed for 1,471,480 person-years. The influenza incidence was higher in the VD cohort than in the control (8.8 vs. 7.8 cases per 1000 person-years). VD cohort had a higher influenza IRR (adjusted IRR 1·13, 95% confidence interval [CI] 1·02-1·25). Severe VD exhibited higher hospitalization risk (adjusted odds ratio [OR] 1·29, 95% CI 1·10-1·20) and increased medical costs. Severe VD was a significant risk factor for mortality (adjusted Hazard Ratio 1·89, 95% CI 1·04-3·45).

CONCLUSIONS

People with VD have a higher influenza incidence, while their outcomes are comparable to those without. Nevertheless, severe VD significantly contributes more to hospitalization, mortality, and medical costs than controls.

Near prescribing trends in two low vision rehabilitation clinics over a ten-year period

CLINICAL RELEVANCE

Optical magnification (OM), electronic magnification (EM), and assistive technology (AT) can be prescribed in low vision rehabilitation (LVR) clinics for near vision goals of patients. This study shows the prescription of OM has not decreased with increased availability of EM and AT.

BACKGROUND

Near visual goals are a primary concern for patients with visual impairment. LVR providers can prescribe OM, EM and/or AT to help. With the rapid evolution and availability of EM and AT, we aim to evaluate if there have been changes in the prescription patterns of clinicians with respect to OM over time. We hypothesise that the increased availability of technology may result in declining prescriptions of OM and increasing prescription of EM and AT over time.

METHODS

This retrospective study investigated near prescribing between 2008-2017 for 530 new patients to the LVR clinics. Examinations were performed by optometrists specialising in low vision. Near devices prescribed included OM and EM and AT.

RESULTS

Most patients attending the LVR clinics were female, over 60 years old and had age related macular degeneration. Near visual goals were a primary concern of 97.2% of the patients. OM was most prescribed in the 0-19 and >60-year-old age groups. Within the 20-39-year-old age group there was the greatest number of both EM and AT prescriptions. OM was most prescribed in patients with visual acuity better than 6/60. EM and AT showed a trend of increasing prescription as visual acuity decreased. EM prescription peaked in <6/60 to 6/240 category while AT trended upwards from <6/21 to no light perception and peaked in patients with no light perception. Referral rates for additional rehabilitation services were 75.7%.

CONCLUSIONS

This study shows that the prescription of OM is not declining even as the prescription and the breadth of electronic magnification and assistive technology available is expanding. OM continues to be a viable option for patients, especially in the youngest and oldest cohorts.

Latent class analysis of chronic disease co-occurrence, clustering and their determinants in India using Study on global AGEing and adult health (SAGE) India Wave-2

Background

Understanding chronic disease prevalence, patterns, and co-occurrence is pivotal for effective health care planning and disease prevention strategies. In this paper, we aimed to identify the clustering of major non-communicable diseases among Indian adults aged ≥50 years based on their self-reported diagnosed non-communicable disease status and to find the risk factors that heighten the risk of developing the identified disease clusters.

Methods

We utilised data from the nationally representative survey Study on Global AGEing and Adult Health (SAGE Wave-2). The eligible sample size was 6298 adults aged ≥50 years. We conducted the latent class analysis to uncover latent subgroups of multimorbidity and the multinomial logistic regression to identify the factors linked to observed latent class membership.

Results

The latent class analysis grouped our sample of men and women >49 years old into three groups - mild multimorbidity risk (41%), moderate multimorbidity risk (30%), and severe multimorbidity risk (29%). In the mild multimorbidity risk group, the most prevalent diseases were asthma and arthritis, and the major prevalent disease in the moderate multimorbidity risk group was low near/distance vision, followed by depression, asthma, and lung disease. Angina, diabetes, hypertension, and stroke were the major diseases in the severe multimorbidity risk category. Individuals with higher ages had an 18% and 15% higher risk of having moderate multimorbidity and severe multimorbidity compared to those in the mild multimorbidity category. Females were more likely to have a moderate risk (3.36 times) and 2.82 times more likely to have severe multimorbidity risk.

Conclusions

The clustering of diseases highlights the importance of integrated disease management in primary care settings and improving the health care system to accommodate the individual's needs. Implementing preventive measures and tailored interventions, strengthening the health and wellness centres, and delivering comprehensive primary health care services for secondary and tertiary level hospitalisation may cater to the needs of multimorbid patients.

Visual environment in schools and student depressive symptoms: Insights from a prospective study across multiple cities in eastern China

OBJECTIVE

To investigate the effects of the school visual environment on depressive symptoms in children and adolescents based on cohort study in eastern China. The school visual environment-related indicators included in this study comprise personal factors (visual impairment) and school-related factors (classroom lighting, school green spaces and school air quality).

METHOD

The follow-up cohort comprises 15,348 students from 283 primary and secondary schools in eastern China. This represents the one-year outcomes of a school-based myopia-mental health cohort study. Data collection includes basic demographics (age, gender, region, etc.), physical examination indicators, behavioral indicators, and school visual environment-related indicators.

RESULT

After a one-year follow-up, we found that compared to the more severe vision impairment group (≤4.0), healthy vision group (≥5.0) had a positive effect against the occurrence of depressive symptoms during consecutive follow-ups, with an RR value of 0.61 (95% CI: 0.57-0.66). Higher values of blackboard illumination appear to be associated with greater positive effects, with an RR (Q75%∼Q100% range) value of 0.87(95% CI: 0.81-0.93). School green spaces seem to exhibit relatively good positive effects when in the Q25%∼Q75% range. The combination of physical activity (Weekly high-intensity exercise) with school air quality(PM2.5≤50%)showed a better positive effect, with an RR value of 0.51(95%CI:0.48-0.55).

CONCLUSION

When addressing students' depressive symptoms, it is crucial to improve the visual environment both at the school level and in students' personal level. Paying appropriate attention to modifiable behaviors, like regular participation in high-intensity exercise sessions, can help alleviate students' depressive symptoms.

Physical and Psychosocial Challenges as Predictors of Vision Difficulty in Children: A Nationally Representative Survey Analysis

PURPOSE

To elicit associations between vision difficulties and physical or psychosocial challenges in children in the United States.

METHODS

Children aged 2-17 years old from the 2021 National Health Interview Survey with data pertaining to vision difficulty were included in our retrospective, population-based analysis. Our primary aim was investigating physical and psychosocial challenges as predictors of vision difficulty. Logistic regression models were performed on Stata version 17.0 (StataCorp LLC, College Station, Texas). Analyses were accompanied by an odds ratio (OR) and 95% confidence interval (CI).

RESULTS

A total of 7,373 children had data pertaining to their level of vision difficulty and were included in our sample. In our multivariable analysis, children with a good/fair (OR = 1.84, 95% CI = [1.31, 2.60], p < 0.01), or poor (OR = 5.08, 95% CI = [1.61, 16.04], p < 0.01) general health status had higher odds of vision difficulty relative to children with an excellent/very good health status. Furthermore, children with difficulties hearing (OR = 8.67, 95% CI = [5.25, 14.31], p < 0.01), communicating (OR = 1.96, 95% CI = [1.18, 3.25], p < 0.01), learning (OR = 1.93, 95% CI = [1.27, 2.93], p < 0.01), and making friends (OR = 1.94, 95% CI = [1.12, 3.36], p = 0.02) had higher odds of vision difficulty. Nonetheless, the following factors were only predictors of vision difficulty in our univariable analysis: requiring equipment for mobility (p < 0.01), experiencing anxiety (p < 0.01), and experiencing depression (p < 0.01).

CONCLUSION

Several factors pertaining to physical and psychosocial challenges in children are associated with vision difficulty. Future research should further explore potential causal links between vision difficulty and physical or psychosocial factors to aid in coordinating public health efforts dedicated to vision health equity.

Vision Problems As a Contributor to Lower Engagement in Care Among Aging Men Living with HIV

PURPOSE

To investigate vision impairment as a barrier to engagement in medical care among aging persons living with HIV (PLWH) who experience multimorbidity and complex care needs.

SETTING

Multicenter AIDS Cohort Study (MACS), a prospective observational cohort of aging PLWH men.

METHODS

We examined relationships of self-reported vision difficulty with indicators of care engagement: 1) adherence to HIV antiretroviral therapy (ART; defined as taking ≥95% of medications); 2) self-reported avoidance of medical care; 3) self-reported tendency to ask a doctor questions about care (>2 questions at a medical visit), as well as with quality of life. A modified version of the National Eye Institute Vision Function Questionnaire was administered at three semi-annual visits (from October 2017 to March 2019) to assess difficulty performing vision-dependent tasks.

RESULTS

We included 1063 PLWH (median age 57 years, 31% Black). Data on care engagement outcomes were analyzed using repeated measures logistic regression with generalized estimating equations adjusted for race, and at visit values for age, education level, depressive symptoms, alcohol use, and smoking status. Compared to no vision difficulty, those reporting moderate to extreme vision difficulty on at least one task had 2.2 times higher odds (95% CI: 1.4, 3.4) of having less than optimal ART adherence, 1.9 times higher odds (95% CI: 1.1, 3.4) of avoiding necessary medical care and median quality of life scores 8 points lower.

CONCLUSION

These findings suggest vision impairment decreases medical care engagement including HIV care and quality of life among aging PLWH.

Self-reported Visual Difficulty, Age-related Eye Disease, and Neuropsychiatric Outcomes in Older Adults

PURPOSE

Self-reported visual difficulty is consistently associated with dementia and other neuropsychiatric outcomes, but studies of specific age-related eye diseases have yielded conflicting results.

METHODS

We conducted a retrospective cohort study using data from The National Health and Aging Trends Study, an ongoing nationally representative survey of older U.S. adults (n = 10,089). All subjects are screened for self-reported visual difficulty annually. Using linked Medicare claims data, we identified subjects with age-related macular degeneration (AMD), primary open-angle glaucoma (POAG), diabetic retinopathy, and cataract. For each condition, controls with complete Medicare eligibility and at least one eye care encounter were selected. We used semiparametric discrete time proportional hazards models to measure associations with incident dementia, and generalized estimating equations to examine longitudinal associations with depression, anxiety, and hallucinations, adjusting for baseline demographics and time-varying comorbidities.

RESULTS

Self-reported visual difficulty was associated with dementia (HR 1.16, 95% CI: 1.00-1.34), depression (OR 1.14, 95% CI: 1.04-1.26), anxiety (OR 1.17, 95% CI: 1.06-1.29), and hallucinations (OR 1.54, 95% CI: 1.29-1.84). Diabetic retinopathy was associated with depression (OR 1.31, 95% CI: 1.05-1.64), and cataracts were associated with a lower risk of depression (OR 0.84, 95% CI: 0.74-0.95) and anxiety (OR 0.86, 95% CI: 0.75-0.99). There were no other associations between age-related eye disease and neuropsychiatric outcomes.

CONCLUSION

Self-reported visual difficulty is associated with dementia and other neuropsychiatric outcomes to a greater degree than age-related eye disease. These findings highlight the distinction between self-reported vision and clinically diagnosed eye disease with regard to health outcomes in older adults.

Relationship between self-reported hearing and vision problems, cognitive decline, depressive symptoms, and life satisfaction in older adults: a retrospective observational study

BACKGROUND

Sensory impairment in older adults is associated with cognitive decline, elevated depressive symptoms, and low levels of life satisfaction. However, these relationships are usually investigated separately and in pairs. This study examined these relationships comprehensively, for the first time.

METHODS

The analysis included 5,658 community-dwelling older adults from the China Health and Retirement Longitudinal Study (aged 50 to 108 years, 52.1% male) who completed the Jorm Informant Questionnaire Cognitive Decline in the Elderly and the Center for Epidemiological Studies-Depression-short form. A questionnaire was used to collect information on hearing, visual status, and life satisfaction. Structural equation modelling was used to examine the direct and indirect relationships between these variables.

RESULTS

Self-reported hearing and vision problems are directly associated with cognitive decline and elevated depressive symptoms. In addition, hearing and vision problems are indirectly related to cognitive decline through elevated depressive symptoms. Although hearing and vision problems had no direct effect on life satisfaction, they were indirectly associated with life satisfaction through cognitive decline and depressive symptoms.

CONCLUSIONS

This study provides the first epidemiological evidence of the comprehensive relationships between hearing and vision problems, cognitive decline, depressive symptoms, and life satisfaction. When older adults report hearing and/or vision problems, clinicians and caregivers should be aware of the concurrence of declined cognition, elevated depressive symptoms, and compensated life satisfaction. Future studies should examine the causal relationships and potential mechanisms of these relationships.

The Association of Retinal Disease with Vision Impairment and Functional Status in Medicare Patients

Background: The association of neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) with functional status in the general Medicare population are not well established. Objectives: This study examined patient-reported survey data linked with Medicare claims to describe the burden of these vision-threatening retinal diseases (VTRDs) among Medicare beneficiaries. Methods: Medicare Current Beneficiary Survey data linked with Medicare Fee-for-Service claims data from 2006 to 2018 were used in a nationally representative retrospective pooled cross-sectional population-based comparison study. Outcomes between community-dwelling beneficiaries with nAMD (n = 1228), DME (n = 101), or RVO (n = 251) were compared with community-dwelling beneficiaries without any VTRDs (n = 104 088), controlling for baseline demographic and clinical differences. Beneficiaries with a diagnosis of nAMD, DME, or RVO during the data year were included; those with other VTRDs were excluded. Outcomes included vision function and loss, overall functioning as assessed by difficulties with activities of daily living (ADLs) and instrumental ADLs (iADLs), anxiety/depression, falls, and fractures. Results: In patient cohorts with nAMD, DME, and RVO, approximately one-third (34.2%-38.3%) reported "a little trouble seeing" (vs 28.3% for controls), and 26%, 17%, and 9%, respectively, reported "a lot of trouble seeing/blindness" (vs 5% of controls). Difficulty walking and doing heavy housework were the most reported ADLs and iADLs, respectively. Compared with those without VTRDs, beneficiaries with nAMD had higher odds of diagnosed vision loss (odds ratio [OR], 5.39; 95% confidence interval, 4.06-7.16; P < .001) and difficulties with iADLs (odds ratio, 1.41; 95% confidence interval, 1.11-1.80; P = .005); no differences were observed for DME or RVO vs control. After adjusting for age, sex, race/ethnicity, poverty status, comorbidities, and other relevant covariates, nAMD, DME, and RVO were not significantly associated with anxiety/depression, falls, or fractures. Discussion: Patients with nAMD or DME were more likely to report severe visual impairment than those without VTRDs, although only those with nAMD were more likely to be diagnosed with vision loss. Conclusions: Patients with nAMD continue to experience more vision impairment and worse functional status compared with a similar population of Medicare beneficiaries despite availability of therapies like antivascular endothelial growth factor to treat retinal disease.

The Underutilization of Mental Health Care Services in the Lives of People with Blindness or Visual Impairment: A Literature Review on Rehabilitation Factors Toward Provision

Purpose

Roughly 3 million adult Americans have a visual impairment or blindness, and over 4 million adults aged 40 and older. Despite data demonstrating an elevated prevalence of mental health symptoms in people with BVI, this population remains largely untreated. Given that people with BVI often interface with multiple systems of rehabilitative care that are designed to improve quality of life, the relatively low rates of initiation of mental health care services are particularly alarming. In this review, the systematic processes of mental health care services across pertinent rehabilitation groups are identified and critically examined.

Patients and Methods

A comprehensive literature review was conducted. The literature review utilized a critical systems typology, whereby relevant literature was selected, reviewed, and analyzed intra and extra organizationally. In addition, a thorough discussion of disability-related factors was provided, lending a socio-political lens to the problem.

Results

Considerable data indicates that short-term mental health care services for people with BVI are ineffective treatment methods, albeit primarily employed in health-rehabilitative processes. Multiple studies offered data indicating the presence of diverse and entangled mental health issues relative to vocational rehabilitation services, mobility tool utility, and emotional reactions to vision loss. Many studies suggested that disability identity work be integrated into health-rehabilitative processes for people with BVI.

Conclusion

To improve the utility of mental health care services for people with BVI, a reenergization of the mental health care needs of this population must occur. A critical podcast or forum focused on educating listeners about the health-rehabilitation factors that influence the provision of mental health care services can aid to improve future mental health policy and practice for people with BVI. Disability scholars need to advance research on integrating critical theories in work with people with BVI and accelerate qualitative, community-based methods to enhance understanding of this population and their unique mental health needs.

How does the UK public think and feel about people with visual impairment: a review of existing evidence

Despite legislation to protect people with visual impairment (V.I.) from discrimination in the United Kingdom (UK), the latter continue to experience overt and covert negative behaviours. Perceived discrimination has been associated with an adverse impact on identity, health and well-being, while negative attitudes have been identified as the biggest barrier to participation in everyday life. This article provides a narrative review of existing evidence of how the UK public treats (behaviours), thinks (perceptions) and feels (attitudes) about people with V.I. Despite limitations, the findings suggest that there is a gap between the behaviours reported by people with V.I. and the attitudes expressed by members of the UK public. Social psychological theories are used to explore possible reasons for this gap, and ways in which it may be addressed. As such, the article provides an example of how social psychological theories can be used to address problems in an applied context.

Functional vision disorder: a review of diagnosis, management and costs

Functional vision disorder (FVD) is a relatively common diagnosis in ophthalmic practice which can be difficult to make because of clinician's apprehension to miss organic pathology. We review the diagnostic approach to patients with FVD, organic mimics of FVD, its diagnostic and management strategies and associated cost burden. Patients with FVD typically present with visual acuity and/or field loss. Diagnostic work-up should include patient observation, detailed history, pupillary examination, dilated ophthalmoscopy, visual field testing and ganglion cell analysis of the macular complex. Most common organic mimickers of FVD are amblyopia, cortical blindness, retrobulbar optic neuritis, cone dystrophy and chiasmal tumours; however, all could be ruled out by structured diagnostic approach. For patients with unilateral visual loss, bottom-up refraction, fogging of the well-seeing eye in the phoropter, convex lens and base-down prism tests could aid in diagnosis. For patients claiming binocular vision loss, checking for eye movement during the mirror test or nystagmus elicited by an optokinetic drum can be helpful. Effective management of FVD involves reassurance, stress reduction and, if agreed on, management of comorbid anxiety and/or depression. The social cost of FVD is predominately economic as patients typically meet several healthcare providers over multiple visits and often undergo several neuroimaging studies before neuro-ophthalmology referral. Further, inappropriate granting of disability benefits confers additional stigma to patients with organic vision loss.

Social functioning in adults with visual impairment from minority ethnic communities in the United Kingdom

Background

Visual impairment (V.I.) has been associated with a negative impact on social functioning, while social support can impact on well-being in those with V.I. Adults from minority ethnic communities (MEC) are projected to make up an increasing proportion of adults living with V.I. in the UK, but limited research has explored their social functioning. This article provides a preliminary insight into social functioning among MEC adults living with V.I. in the UK.

Methods

The article reports findings from a secondary analysis of V.I. Lives survey data. V.I. Lives was a UK telephone survey, which explored the life experiences of people with V.I. across a wide range of topics including social functioning. This secondary analysis explored social participation, support, isolation, and relationships among a matched control sample of 77 MEC and 77 adults aged 18 and over from White communities (WC). Participants were matched on age, gender, UK region and urban/rural setting. Subgroup analyses were also conducted for the two largest subgroups within the MEC group, Asian (n = 46) and Black participants (n = 22).

Results

Contact with like-minded people (U = 2174.50, p = 0.003, r = -0.24) and opportunities to take part in more social activities (U = 2253.50, p = 0.007, r = -0.22) was significantly more important to MEC than WC participants. Moreover, MEC participants were significantly less likely to feel supported by friends/family (U = 3522.50, p = 0.017, r = 0.19) and had fewer people they could ask for help (U = 3775.50, p = 0.001, r = 0.26), but there were no significant differences in the perceived impact of V.I. on their friendships/social life and marriage/relationship, their ability to take part in a range of activities, nor their marital status. Asian participants were significantly more likely than Black participants to feel cut off from the people and places around them (U = 655.50, p = 0.042, r = 0.25). Effect sizes were overall small. Although there were no further statistically significant differences between the two groups, Asian participants were also less likely to be able to take part in activities, and more likely to report a negative impact on their social life/friendships and on their marriage/relationship, as well as a smaller social network.

Conclusion

The findings suggest that V.I. may have had a greater impact on social functioning among Asian participants in this sample, including on experiences of social isolation and participation in social activities. Future research will need to confirm these findings and explore the possible reasons.

Access to eye care and support services among adults from minority ethnic communities living with visual impairment in the United Kingdom

Background

Despite an increased risk of certain eye conditions which can lead to visual impairment (V.I.), there is evidence of a greater delay to treatment-seeking among adults from minority ethnic communities (MEC). MEC adults may also be underrepresented on V.I. registers, within early intervention services, and among the beneficiaries of national V.I. charities. However, much of this evidence is outdated or anecdotal.

Methods

This secondary analysis of V.I. Lives survey data explored use of eye health and support services and mobility aids among a matched control sample of 77 MEC and 77 adults aged 18 and over from white communities (WC). Participants were matched on age, gender, UK region and urban/rural setting. Additional subgroup analysis was conducted for Asian (n = 46) and black participants (n = 22).

Results

There were no significant group differences in areas such as eye health service use, registration status, contact with charities, and level of practical support received. But MEC participants were significantly more likely than WC participants to have received direct payments from social services to cover their care needs, Χ2 (1, 154) = 8.27, p = 0.004, and to use apps on their mobile for mobility, Χ2 (1, 154) = 5.75, p = 0.017. In contrast, WC participants were significantly more likely to agree that they were getting the level of emotional support to get on with their life, U = 3,638, p = 0.010, to feel confident to ask their friends for support, U = 2,416, p = 0.040, and to have a guide dog for mobility, Χ2 (1, 154) = 3.62, p = 0.057, although the latter did not reach statistical significance. Within the MEC group, Asian participants were significantly more likely than black participants to use a long cane, Χ2 (1, 68) = 7.24, p = 0.007, but they were significantly less likely to agree that they had received the right level of support when they started to experience V.I., U = 236.5, p = 0.040.

Conclusion

The preliminary findings suggests that there is scope to increase support provided by V.I. charities and the V.I. register, although, contrary to existing evidence, there were no statistically significant differences in eye health service use, registration status and use of wider support services. Further research is required to confirm these findings and explore reasons for differences.

Association of changes in self-reported vision and hearing impairments with depressive symptoms in middle-aged and older adults: Evidence from a nationwide longitudinal study in China

OBJECTIVE

This study assessed the longitudinal relationship between changes in self-reported vision impairment (VI) and hearing impairment (HI), and depressive symptoms in adults aged ≥45 years.

METHODS

Data from the China Health and Retirement Longitudinal Study for 2015 and 2018 were used, with a sample size of 10,050. VI and HI were self-reported. The 10-item Center for Epidemiologic Studies Depression Scale (CES-D10) was used to assess depressive symptoms. Total scores and clinically significant depressive symptoms (CES-D10 scores ≥ 10) were used as outcomes and analyzed using generalized estimating equations with identity link and logit link functions.

RESULTS

Of all changes in HI with good vision, only persistent HI was associated with higher CES-D10 scores (OR 95% CI: 1.09-3.30). Both new-onset and persistent VI with good hearing were associated with CES-D10 scores (OR 95% CI, new-onset: 1.70-3.52; persistent: 1.58-2.78) and clinically significant depressive symptoms (OR 95% CI, new-onset: 1.41-2.56; persistent: 1.36-2.27). Persistent dual sensory impairment (DSI) was associated with the highest CES-D10 scores (OR 95% CI: 3.63-5.97) and the highest risk of clinically significant depressive symptoms (OR 95% CI: 1.78-2.85). Those who self-reported improvements in vision and hearing still had higher CES-D10 scores (OR 95% CI: 1.35-2.83) and a higher risk of clinically significant depressive symptoms (OR 95% CI: 1.03-2.02) than those maintaining good vision and hearing.

CONCLUSION

Self-reported VI and DSI are closely associated with depressive symptoms. Because VI and DSI are modifiable, interventions for them could also prevent depressive symptoms.

Emotional well-being in Charles Bonnet syndrome: exploring associations with negative affect, loneliness and quality of life

Background

Charles Bonnet syndrome (CBS) is a condition characterised by the occurrence of vivid and complex visual hallucinations in individuals with visual impairment.

Objective

To explore the relationship between emotional distress and the perceived impact of CBS symptoms on participants' lives. We tested the hypothesis that heightened negative affect was associated with a more negative appraisal of CBS symptoms, increased self-reported loneliness, and poorer quality of life (QOL).

Design

Cross-sectional.

Methods

Participants recruited predominantly via vision-related charities rated their hallucinations and their impact on a Likert scale. Loneliness and negative affect were assessed with the Three-Item Loneliness Scale and Positive and Negative Affect Schedule. Health index (EQ-5D-3L) and vision-related QOL (VF-9) were also assessed. Correlation analysis and multi-variable regression determined the relation between survey responses.

Results

The majority of 126 respondents (81%) were aged 65+ years and 84% reported active CBS symptoms. Fifty-five percent of respondents rated impact of CBS as negative and no-one rated the impact as 'very pleasant'. A statistically significant correlation was found between impact of CBS and negative affect (p ⩽ 0.001; rho = -0.34) and impact of CBS and loneliness (p = 0.017; rho = -0.21). The relation between negative affect and CBS impact remained statistically significant when accounting for the impact of loneliness and the relationship between loneliness and CBS effect (p = 0.002, adj R 2 = 0.1). A statistically significant correlation between loneliness and negative affect (p ⩽ 0.001; rho = 0.55) was also found.

Conclusion

Respondents experiencing negative emotions were more likely to perceive the impact of CBS symptoms as negative and report greater feelings of loneliness. Negative affect is an important consideration when assessing people with CBS.

The Association of Vision Concerns With the Physical and Mental Well-being of Adolescents in the United States

PURPOSE

To describe the prevalence of vision concerns among US adolescents and the association of time spent worrying about eyesight with physical and mental health.

DESIGN

Cross-sectional study.

METHODS

This study included adolescent children (age 12 to ≤18 years) particpating in the 2005-2008 National Health and Nutrition Examination Survey with completed visual function questionnaires and eye examinations. Vision concerns were identified by a survey question of time spent worrying about eyesight and response was treated as a dichotomous variable. Recent poor physical and mental health was defined as at least 1 day of poor health within the last month. Odds ratios (ORs) derived from survey-weighted multivariable logistic regression models were used to identify factors associated with vision concerns in the adolescent population, adjusting for participant demographics and refractive correction.

RESULTS

The survey participants included 3100 adolescents (mean [SD] age, 15.5 [2.0] years; 49% [n = 1545] female). Vision concerns were expressed by 24% (n=865) of adolescents. Vision concerns were more prevalent among female (29% vs 19%, P < .001), low-income (30% vs 23%, P < .001), and uninsured (31% vs 22%, P = .006) adolescents. Participants worried about their eyesight were more likely to have undercorrected refractive error (OR 2.07, 95% CI 1.43-2.98). Poor recent mental health (OR 1.30, 95% CI 1.01-1.67), but not physical health (OR 1.00, 95% CI 0.69-1.45), was associated with adolescent vision concerns.

CONCLUSIONS

Female, low-income, and uninsured adolescents living in the United States are more likely to report worrying about their vision and often have uncorrected or undercorrected refractive errors.

Multiple Sclerosis vision questionnaire (MSVQ-7): Reliability, validity, precision and discrimination

BACKGROUND

Visual dysfunction is common in people with Multiple Sclerosis (pwMS), associated with a variety of visual symptoms. Capturing the patient experience of these complex patterns of visual pathology is challenging. A valid and reliable patient reported measure, capable of detecting clinically significant change, would have considerable research and clinical benefits. We examined the properties of the MS Vision Questionnaire (MSVQ-7) in a large MS population.

METHODS

Data were collected from participants in the UK-wide Trajectories of Outcome in Neurological Conditions-MS (TONiC-MS) study: MS subtype and Expanded Disability Status Scale (EDSS) band from the clinical team, as well as serial packs including the MSVQ-7 and questionnaires on depression, anxiety and stigma. A calibration sample of 1000 pwMS contributing several years of follow-up were split into training and validation samples for a Confirmatory Factor Analysis and Rasch analysis. The Minimal Detectable Change (MDC) was computed as well as the Minimal Clinically Important Change (MIC), by an anchor-based method, for different MS subtypes.

RESULTS

The MSVQ-7 is unidimensional and can be fit to the Rasch model with a solution discarding 3% of variance. Providing all 7 items are answered, the total can be converted to an interval-level metric for calculation of change scores and other parametric analyses. The % of missing values did not exceed 1.7%. Among 5478 pwMS, 80% reported visual problems. MSVQ-7 scores were categorised as mild for 36.1%, moderate for 33.6% and severe for 10.3%, and varied by MS subtype. In the follow-up sample of 2227 pwMS, 42.5% changed MSVQ-7 category between baseline and first follow-up (mean 22.6 months). The MIC exceeded the MDC so clinically significant change exceeds measurement error. While MDC was identical for relapsing and progressive MS, MIC varied by MS subtype, with smaller MIC in relapsing MS. Over one-quarter of the follow-up sample reported a clinically significant change in MSVQ-7: 12.2% improved and 13.5% deteriorated. For pwMS recruited within 2 years of diagnosis, 17.3% reported significant change on follow-up, all improving. MSVQ-7 scores showed strong associations with anxiety, depression and stigma (effect sizes>0.8). Duration, EDSS band and MS subtype all had effect sizes 0.2-0.49. A multinomial logistic regression exploring vision disturbance and depression, adjusted for age, gender, MS subtype, duration and disability, showed vision is the strongest significant predictor of depression. Each unit increase in interval MSVQ-7 increases risk by 10% of 'possible' and by 17% of 'probable' depression.

CONCLUSIONS

The MSVQ-7 is a brief self-report measure of visual problems for pwMS. It can easily be converted to interval-level measurement for change scores or power calculations and has good precision and discrimination. Visual problems were reported by 80% of pwMS and changed over time, evidencing the need for regular monitoring. MIC varied by MS subtype, indicating that perception of impact changes over the disease course. Visual dysfunction significantly affects depression risk and perceived stigma, highlighting the importance of routine assessment of visual problems in comprehensive care. The MSVQ-7 has strong psychometric properties for adoption as a measure for vision in clinical and research settings.

The impact of childhood glaucoma on psychosocial functioning and quality of life: a review of the literature

We present a novel comprehensive literature review of studies of the psychosocial functioning (PF) and quality of life (QoL) of patients with childhood glaucoma and their caregivers. Our findings demonstrate variable study quality and approach, as well as inconsistent results relating to the association of glaucoma-specific factors and sociodemographic variables with measured PF and QoL. Future studies should focus on the development of culturally cognizant and standardized assessment tools, execution of multi-center longitudinal studies with global representation, evaluation of PF and QoL among siblings and childhood glaucoma providers, and implementation of interventions to improve patient and caregiver PF and QoL.

Prevalence and Risk Factors of Major Depression in Patients with Diabetic Retinopathy in a Nationally Representative Survey

PURPOSE

Evaluate the prevalence and risk factors of depression in diabetic retinopathy (DR). Compare subjective and objective measures of visual function predictivity of depression.

METHODS

National Health and Nutrition Examination Survey 2005-2008 participants aged ≥40 who underwent fundus photography, Patient Health Questionnaire (PHQ)-9, and Visual Function Questionnaire (VFQ-25) were included in the study. Multivariable logistic regression was used to evaluate whether DR was a significant risk factor for depression and to evaluate the risk factors for depression in those with DR.

RESULTS

A total of 5704 participants, 47% male, and mean age 56.5 years were included in this study. Persons with moderate, severe non-proliferative diabetic retinopathy (NPDR), or proliferative retinopathy (PDR) had higher prevalence of depression than participants with mild retinopathy or no retinopathy (14.3%, 6.9%, 7.0%). Moderate-to-severe NPDR or PDR (OR: 2.36, p = .04) was associated with depression. Among persons with DR, best-corrected visual acuity and HbA1c were not associated with depression. However, self-reported measures of vision were associated with depression: some of the time spent worrying about eyesight (OR: 4.59, p = .010), vision limit activities some of the time (OR: 8.52, p < .001), vision limits activities most/all of the time (OR: 6.99, p < .001).

CONCLUSIONS

A significant proportion of patients with DR in the NHANES population had co-morbid major depression. Best corrected visual acuity was not associated with depression in those with DR, while subjective, self-reported measures were associated with depression, suggesting subjective measures are a better determinant of poor mood and low functional status.

Exploring mental well-being, the emotional impact of visual impairment and experiences of prejudice and discrimination among adults from minority ethnic communities in the UK

Background

Visual impairment (V.I.) has been associated with a negative impact on mental health outcomes, including a process of grief among those who lose their sight. Older adults with V.I. who had experienced discrimination have been found to be at increased risk of depression, loneliness, poorer life satisfaction and poorer quality of life. Adults from minority ethnic communities (MEC) may be at increased risk of V.I. and yet, research on the experiences of MEC adults with V.I. remains limited. This article forms part of a series which explores issues and status among MEC adults living with V.I. in the UK.

Methods

A secondary analysis of V.I. Lives survey data was performed to explore mental well-being assessed by the short Warwick-Edinburgh Mental Well-being scale (SWEMWBS), the emotional impact of V.I., and prejudice and discrimination among a matched control sample of 77 MEC and 77 adults from white communities (WC). Participants were matched by age, gender, UK region and urban/rural setting. Subgroup analyses were also conducted for the two largest MEC subgroups, Asian (n = 46) and black participants (n = 22).

Results

There were few statistically significant differences between the groups. MEC participants were significantly more likely than WC participants to rate emotional support to come to terms with their V.I. as important and to feel optimistic about their V.I. but they were significantly less likely to agree that they were receiving the level of emotional support they needed to get on with their life. Within the MEC group, participants from Asian communities had significantly poorer mental well-being, and they were also significantly more likely to agree that the general public were often prejudiced against people with V.I. and less likely to feel optimistic about their V.I. than black participants.

Conclusion

Although there were few statistically significant differences, participants from Asian communities were more likely to report poor mental and emotional well-being, and experiences of discrimination, than black and white participants. In contrast, participants from black communities fared the same as, or in some cases better than, white participants. Future research will need to confirm these findings and explore reasons for these.

Risk factors for poorer quality of life in patients with neovascular age-related macular degeneration: a longitudinal clinic-based study

BACKGROUND/OBJECTIVES

To examine the risk factors for poor vision-related and health-related quality of life (QoL) in patients with neovascular age-related macular degeneration (nAMD) who present for anti-vascular endothelial growth factor (anti-VEGF) therapy.

METHODS

In a clinic-based cohort of 547 nAMD patients who presented for treatment, the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ25), Short-Form 36 (SF-36) and EuroQoL EQ-5D-5L questionnaires were administered to assess vision-related and health-related QoL. Of these, 83 participants were followed up one-year later to provide longitudinal data.

RESULTS

Individuals with mild or moderate visual impairment or blindness at baseline had significantly lower NEI-VFQ-25 scores at follow-up. The presence of ≥3 chronic diseases was associated with lower SF-36 mental component scores (MCS) (p = 0.04) and EQ-VAS scores (p = 0.05). Depressive symptoms were associated with significantly lower MCS (p < 0.0001) and EQ-VAS scores (p = 0.02). Individuals with versus without impaired basic activities of daily living (ADLs) exhibited NEI-VFQ-25 and EQ-VAS scores that were 10.96 (p = 0.03) and 0.13 (p = 0.02) points lower. Those with impaired instrumental ADLs scored 11.62 (p = 0.02), 13.13 (p < 0.0001) and 15.8 (p = 0.0012) points lower in the NEI-VFQ-25, SF-36 physical component score and EQ-5D-5L summary score, respectively.

CONCLUSIONS

The QoL of nAMD patients is affected by visual acuity as well as patients' medical history, mental health and functional status.

Association between vision impairment and depression: a 9-year, longitudinal, nationwide, population-based cohort study in South Korea

BACKGROUND/AIMS

Vision impairment (VI) increases the risk of various comorbidities, including depression. However, the relationship between depression and VI is unclear, and existing findings are inconsistent. We therefore investigated the risk of depression in adults before and after their registration as visually impaired.

METHODS

In this longitudinal, nationwide, retrospective cohort study, 131 434 patients (aged ≥18 years) with newly registered VI during 2005-2013 were evaluated using the Korean National Health Insurance Service database. Using 1:1 propensity score matching, randomly selected patients (control group) were compared with patients with VI (patient group) according to age, sex, residential area and household income. Each patient was tracked from 3 years before and 5 years after registration. The risk of depression before and after VI registration was evaluated using a conditional logistic regression model.

RESULTS

The risk of depression gradually increased from 3 years before registration (OR, 1.186; 95% CI 1.089 to 1.290), then peaked at the time of registration (OR, 1.925; 95% CI 1.788 to 2.073), and then gradually decreased until 5 years after registration (OR, 1.128; 95% CI 1.046 to 1.216). Male patients, those with severe VI and those aged 18-29 years had a higher risk of depression.

CONCLUSIONS

Patients with VI had an increased risk of depression from 3 years before to 5 years after registration. Significant risk factors included severity, male sex and younger age. Thus, public mental health services are necessary to provide appropriate support and interventions to people before and after registration as visually impaired.

Analytical method for detecting outlier evaluators

BACKGROUND

Epidemiologic and medical studies often rely on evaluators to obtain measurements of exposures or outcomes for study participants, and valid estimates of associations depends on the quality of data. Even though statistical methods have been proposed to adjust for measurement errors, they often rely on unverifiable assumptions and could lead to biased estimates if those assumptions are violated. Therefore, methods for detecting potential 'outlier' evaluators are needed to improve data quality during data collection stage.

METHODS

In this paper, we propose a two-stage algorithm to detect 'outlier' evaluators whose evaluation results tend to be higher or lower than their counterparts. In the first stage, evaluators' effects are obtained by fitting a regression model. In the second stage, hypothesis tests are performed to detect 'outlier' evaluators, where we consider both the power of each hypothesis test and the false discovery rate (FDR) among all tests. We conduct an extensive simulation study to evaluate the proposed method, and illustrate the method by detecting potential 'outlier' audiologists in the data collection stage for the Audiology Assessment Arm of the Conservation of Hearing Study, an epidemiologic study for examining risk factors of hearing loss in the Nurses' Health Study II.

RESULTS

Our simulation study shows that our method not only can detect true 'outlier' evaluators, but also is less likely to falsely reject true 'normal' evaluators.

CONCLUSIONS

Our two-stage 'outlier' detection algorithm is a flexible approach that can effectively detect 'outlier' evaluators, and thus data quality can be improved during data collection stage.

Screening for Patients with Visual Acuity Loss in Primary Health Care: A Cross Sectional Study in a Deprived Hungarian Population

Screening for visual acuity loss (VAL) is not applied systematically because of uncertain recommendations based on observations from affordable countries. Our study aimed to evaluate the effectiveness of primary health care-based screening. A cross-sectional investigation was carried out among adults who did not wear glasses and did not visit an ophthalmologist in a year (N = 2070). The risk factor role of sociodemographic factors and the cardiometabolic status for hidden VAL was determined by multivariable linear regression models. The prevalence of unknown VAL of at least 0.5 was 3.7% and 9.1% in adults and in the above-65 population. Female sex (b = 1.27, 95% CI: 0.35; 2.18), age (b = 0.15, 0.12; 0.19), and Roma ethnicity (b = 2.60, 95% CI: 1.22; 3.97) were significant risk factors. Higher than primary school (b_{secondaryschoolwithoutgraduation} = -2.06, 95% CI: -3.64; -0.47; and b_{secondaryschoolwithgraduation} = -2.08, 95% CI: -3.65; -0.51), employment (b = -1.33, 95% CI: -2.25; 0.40), and properly treated diabetes mellitus (b = -2.84, 95% CI: -5.08; -0.60) were protective factors. Above 65 years, female sex (b = 3.85, 95% CI: 0.50; 7.20), age (b = 0.39, 95% CI: 0.10; 0.67), Roma ethnicity (b = 24.79, 95% CI: 13.83; 35.76), and untreated diabetes (b = 7.30, 95% CI: 1.29; 13.31) were associated with VAL. Considering the huge differences between the health care and the population's social status of the recommendation-establishing countries and Hungary which represent non-high-income countries, the uncertain recommendation of VAL screening should not discourage general practitioners from organizing population-based screening for VAL in non-affordable populations.

A Population-Based Cohort Study of the Association between Visual Loss and Risk of Suicide and Mental Illness in Taiwan

The psychosocial and health consequences of ocular conditions that cause visual impairment (VI) are extensive and include impaired daily activities, social isolation, cognitive impairment, impaired functional status and functional decline, increased reliance on others, increased risk of motor vehicle accidents, falls and fractures, poor self-rated health, and depression. We aimed to determine whether VI increases the likelihood of a poor prognosis, including mental illness, suicide, and mortality over time. In this large, location, population-based, nested, cohort study, we used data from 2000 to 2015 in the Taiwan National Health Insurance Research Database (NHIRD), which includes diagnoses of all the patients with VI. Baseline features, comorbidities, and prognostic variables were evaluated using a 1:4-matched cohort analysis. Furthermore, comparisons were performed using Cox regression and Bonferroni-correction (for multiple comparisons) to study the association between VI and poor prognosis (mental illness, suicide). The study outcome was the cumulative incidence of poor prognosis among the visually impaired and controls. A two-tailed Bonferroni-corrected p < 0.001 was considered statistically significant. Among the 1,949,101 patients enlisted in the NHIRD, 271 had been diagnosed with VI. Risk factors for poor prognosis and the crude hazard ratio was 3.004 (95% confidence interval 2.135-4.121, p < 0.001). Participants with VI had an increased risk of poor prognosis according to the sensitivity analysis, with a poor prognosis within the first year and first five years. VI was associated with suicide and mental health risks. This study revealed that patients with VI have a nearly 3-fold higher risk of psychiatric disorders, including anxiety, depression, bipolar, and sleep disorders, than the general population. Early detection through comprehensive examinations based on increased awareness in the clinical context may help maintain visual function and avoid additional complications.

Prevalence of depression in visually impaired children and adolescents: A systematic review and meta-analysis

The prevalence of depression among visually impaired or blind children and adolescents has not been systematically reviewed. This study aims to provide the prevalence of depression among visually impaired or blind children and adolescents. This systematic review and meta-analysis were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines (PRISMA) (2020) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. A systematic search of various online databases was done to identify and include studies reporting the prevalence of depression among visually impaired or blind children and adolescents (aged up to 20 years). A random-effects meta-analysis was used to estimate the pooled prevalence of depression. Heterogeneity was assessed using I² to explain heterogeneity meta-regressive analysis and subgroup analyses were done. With the finally selected 13 studies consisting of 822 participants, the overall pooled prevalence of depression or dysthymia among visually impaired children or adolescents was 14% (137/822 individuals, 95% CI = 9% to 20%), with high heterogeneity between studies (I² = 80.11%; P < 0.001). Five studies that expressed gender distribution showed a cumulative prevalence of diagnosed depressive disorders was 6.85% and 18.96%, respectively, for male (n = 219, I² = 47.52) and female (n = 116, I² = 60.6%) participants. In this systematic review and meta-analysis, we selected and analyzed 13 studies and estimated pooled prevalence of depression was 14% (95% CI = 9% to 20%), among visually impaired or blind children and adolescents.

Anxiety and Depression after Traumatic Open-Globe Injury

Introduction

This cross-sectional interview-based study aimed to assess the prevalence and severity of probable anxiety and depression in patients with traumatic open-globe injury and to identify factors associated with anxiety and depression following open-globe injury.

Methods

Two hundred and twenty-five patients with open-globe injury were identified at the UC Davis Medical Center between 2008 and 2019. Prisoners and patients under 18 at the time of recruitment were excluded from the study. One hundred and twenty-four patients provided consent to participate in the study, which involved a phone interview and chart review. The interview consisted of a section on sociodemographic data and potential associations followed by the Hospital Anxiety and Depression Scale, a standardized 14-question survey that has been validated in previous studies as an excellent predictor of anxiety and depression. A score of 8 for anxiety or depression was considered a positive test, and patients with a positive test in either category were advised to seek further evaluation with their primary care doctors. The prevalence of probable anxiety and depression was calculated, and linear regression was used to identify factors associated with anxiety and depression.

Results

The average age was 50.5 ± 19.2, and 75.8% of patients were male. The anxiety score was positive in 37.9% of patients and the depression score was positive in 28.2%. The mean anxiety and depression scores were 6.3 ± 4.7 and 5.5 ± 4.8, respectively. The P value of the linear regressions for anxiety score and depression score were both < 0.001, with R2 = 0.429 and 0.363, respectively. Younger age (P = 0.002) and unemployment at the time of the interview (P = 0.038) were associated with higher anxiety scores. Patients who were bothered by the appearance of their injured eye had higher anxiety scores (P < 0.001) and depression scores (P < 0.001). Patients without a high school diploma had higher depression scores (P < 0.001). Gender, enucleation status, number of people in support network, use of a prosthetic or scleral shell, final logMAR visual acuity, marital status, months since the initial injury, and presence of an intraocular foreign body were not significantly associated with anxiety or depression scores.

Conclusions

Traumatic open-globe injury is associated with a high prevalence of probable anxiety and depression. Dissatisfaction with the appearance of the injured eye was associated with higher anxiety and depression scores. Younger age and unemployment were associated with increased anxiety scores, and lack of a high school diploma was associated with higher depression scores.

Serum lactate dehydrogenase is associated with impaired lung function: NHANES 2011-2012

BACKGROUND

Serum lactate dehydrogenase levels reflect disease status in a variety of organs, but its role in indicating pulmonary function is not yet clear. Therefore, this study explored the correlation between pulmonary function and serum lactate dehydrogenase, and investigated thresholds for changes in pulmonary function indicators in the total population as well as in different strata of the population.

METHODS

Based on data from the National Health and Nutrition Examination Survey (NHANES) 2011-2012 (n = 3453), univariate and stratified analyses were performed to investigate factors associated with pulmonary function, and multiple regression analysis was used to further investigate the specific relationship with serum lactate dehydrogenase. Smoothed curve fitting, threshold effect and saturation effect analysis were used to explore the threshold level of serum lactate dehydrogenase at the onset of changes in pulmonary function indicators.

RESULTS

Adjusted smoothed curve fit plots showed a linear relationship between serum lactate dehydrogenase levels and forced vital capacity and forced expiratory volume in one second: for each 1 U/L increase in serum lactate dehydrogenase levels, forced vital capacity decreased by 1.24 mL (95% CI = -2.05, -0.42, P = 0.0030) and forced expiratory volume in one second by 1.11 mL (95% CI = -1.82, -0.39, P = 0.0025).

CONCLUSIONS

Serum lactate dehydrogenase was negatively and linearly correlated with pulmonary function indices in the total population analyzed. Based on the total population and different population stratifications, this study determined the threshold values of serum lactate dehydrogenase at the onset of decline of pulmonary function in different populations. This provides a new serological monitoring indicator for patients suffering from respiratory diseases and has implications for patients with possible clinical impairment of pulmonary function. However, our cross-sectional study was not able to determine a causal relationship between these two factors, and further research is needed.

Effects of duration and number of symptoms on vision-related anxiety in patients with Inherited Retinal Diseases

BACKGROUND

Patients with Inherited Retinal Diseases (IRDs) are at increased risk for vision-related anxiety due to progressive and irreversible vision loss, yet little is known about risk factors for anxiety in these patients.

MATERIALS AND METHODS

This was a single-center, retrospective cross-sectional study at a large academic center. 128 adults with an IRD and without other significant eye conditions were recruited between December 2016 and March 2020. Participants were asked about the duration and number of symptoms they had in the following vision domains: reading, contrast vision, color vision, glare/light sensitivity, night vision, and peripheral vision. The outcomes of interest were the two domains of the Michigan Vision-Related Anxiety Questionnaire (MVAQ), rod- and cone-function related anxiety. We conducted an adjusted analysis to isolate the independent effect of duration and number of symptoms on vision-related anxiety.

RESULTS

Of 126 participants had complete data, 62 (49%) were female and 64 (51%) were male, with an average age of 49 years (range: 18-87). Patients with duration of symptoms for greater than 25 years had an adjusted anxiety theta that was one-half standard deviations lower than patients with symptoms for less time. Patients with higher number of symptoms had higher anxiety theta after adjusting for confounding variables (p < 0.0001).

CONCLUSIONS

The number of symptoms but not the duration of symptoms, is an independent risk factor for vision-related anxiety. Patients with more symptoms are at higher risk for vision-related anxiety. Having symptoms for longer than 25 years may reduce this anxiety.

A rapid review of evidence relating to service use, experiences, and support needs of adults from minority ethnic communities along the eyecare pathway in the United Kingdom

Background

There is growing awareness of the health inequalities experienced by minority ethnic communities, who make up an increasing proportion of the United Kingdom (UK) population and have been found to be at increased risk of visual impairment (V.I.). V.I. impacts on a wide range of life domains including employment, social functioning and activities of daily living. Considering existing health inequalities, the increased risk of V.I. and its wide-ranging impact, it is important to understand the experiences of adults from minority ethnic communities living with V.I. in the UK.

Methods

A rapid evidence review of academic and gray literature published since 2005 and in English was performed. A search of AMED, CINAHL Plus and MEDLINE via EBSCOhost identified 969 articles. Articles were included in the review if they reported findings relating to the UK-context, to adults from minority ethnic communities living with V.I., and to experiences of V.I. and the eyecare pathway.

Results

A total of 11 academic articles and 4 charity reports presented findings relating to perceptions of V.I. and eye disease (n = 3), access to services and service use (n = 5), impact of interventions (n = 7), the wider impact of V.I. (n = 2), and registration status (n = 1). Much of the literature focused on primary eyecare resulting in a comprehensive list of barriers and recommendations to increase eye tests. Less research addressed experiences and use of services further along the eyecare pathway although use of services may be low. Overall, the research on the experiences of adults with V.I. from minority ethnic communities in the UK remains anecdotal, outdated or unavailable. There are substantial gaps in the evidence relating to the wider impact of V.I., the impact of perceptions of V.I., and the use of services beyond primary eyecare.

Conclusions

This review summarizes our current knowledge of the experiences of adults from minority ethnic communities living with V.I. in the UK and highlights substantial gaps in the evidence. The findings provide practical implications for practitioners and researchers committed to addressing health inequalities in the field of eyecare in the UK.

Self-reported visual impairment and depression of middle-aged and older adults: The chain-mediating effects of internet use and social participation

Background

Visual impairment (VI) is a strong predictor of depression in middle-aged and older adults. However, the underlying mechanisms and pathways have not been well characterized. The purpose of this study was to determine whether Internet use and social participation mediate the effects of self-reported VI on depression.

Methods

The study used the fourth wave of cross-sectional data from the China Health and Retirement Longitudinal Study, including 19,766 Chinese adults. Depression was assessed according to the CES-D 10 International Scale. Logistic regression models were used to examine the relationship between self-reported VI and depression. While adjusting for relevant covariates, the PROCESS macro (model nos. 6 and 91) was used to assess the chain-mediating effects of Internet use and social participation.

Results

A total of 17,433 respondents were included in this study. The CES-D 10 results showed that 7,327 middle-aged and older adults had depressive symptoms, of whom 39.5% were male and 10.2% were ≥75 years old. 32.1% of respondents self-reported VI. Regression analysis showed a positive association between VI and depression, while Internet use and social participation had a negative predictive effect on depression. In the mediation analysis, the social participation pathway contributed the most to the total effect, accounting for 52.69% of it. The proportion of Internet use is 37.72%. When these two mediators were considered together in the full model, they accounted for 9.58% of the total effect of VI on depression.

Conclusion

Internet use and social participation were important mediators that mitigated the effects of VI on depression. Combined with previous evidence, online activities such as e-health and m-health can effectively promote disease monitoring and diagnosis, and various offline social participation activities can also play a role in regulating emotions. Therefore, Internet use and social participation factors may serve as relevant entry points for the development of intervention programs that may further improve the mental health of the visually impaired.

Knowledge and perception of clinical physiotherapy students about physiotherapy management of stroke survivors with visual impairment

It is evident from clinical practice that visual disorders are prevalent in stroke medicine and are involved in all stages. The visual disorder may form all or part of the initial presentation, and subsequently, visual problems may be a rehabilitation issue or affect the quality of life and activities of daily living (ADLs) after stroke. This study aimed to determine the level of knowledge and perception of the clinical students of the Department of Medical Rehabilitation, Nnamdi Azikiwe University, about stroke survivors with visual impairment (SSVI) and the physiotherapy management of stroke survivors who are visually impaired. This study was a cross-sectional survey involving 136 respondents who were selected from the 270 clinical students of the Department of Medical Rehabilitation at Nnamdi Azikiwe University. A 25-item questionnaire was administered to assess their level of knowledge and perception of SSVI as well as the physiotherapy management methods involved. Descriptive statistics of tables, mean, and standard deviation were used to summarize participants’ responses. The Spearman rank-order correlation was used to test for correlations. Mann–Whitney U test was used to assess sex differences. Alpha was set at .05. There was a high level of knowledge and high perception (94.1% and 91.9%) of physiotherapy management of SSVI among the clinical physiotherapy students. The level of the study did not significantly influence the knowledge ( p = .386) and perception ( p = .686) of the visually impaired stroke survivor. There was a significant ( p = .008) relationship between age and knowledge of stroke survivors. No significant gender difference was observed in all results. The student’s age and gender did not influence their knowledge or perception of physiotherapy management for SSVI, the student’s level of study did influence the two variables.

Association of vision impairment with suicide ideation, plans, and attempts among adults in the United States

OBJECTIVE

This study aims to investigate the relative strength of association between vision impairment (VI) and suicidal ideation, plans, and attempts among adults in the United States.

METHOD

The study sample consisted of 214,505 adults, aged 18 years and older. Researchers used data from the 2015-2019 National Survey on Drug Use and Health, in which respondents were asked whether they had any suicidal thoughts, plans, and attempts, in the past 12 months.

RESULTS

Approximately, 4.4% of respondents reported experiencing VI, being blind, or having serious difficulty seeing. Compared to their sighted peers, a relatively high proportion of adults with VI had serious thoughts about suicide (9.0%), suicidal plans (3.0%), or suicidal attempts (1.6%) in the past year. The findings showed that individuals with VI may disproportionately experience suicidal ideation, plans, and attempts, after controlling potentially confounding variables (adjusted odds ratio [AOR] = 1.36; AOR = 1.27; AOR = 1.40, respectively).

CONCLUSION

With findings demonstrating such a strong association between VI and suicide, this study suggests the importance of screening for suicidal ideation, plans, and attempts among adults with VI, and the strong need for developing behavioral health services which keep this correlation in mind.

Sex-specific alterations of cortical morphometry in treatment-naïve patients with major depressive disorder

Major depressive disorder (MDD) shows sex differences in terms of incidence and symptoms, but the neurobiological basis underlying these sex differences remains to be clarified. High resolution T1-weighted Magnetic Resonance Imaging (MRI) scans were obtained from 123 non-comorbid treatment-naïve individuals with MDD and 81 age-, sex-, and handedness-matched healthy controls (HCs). MRI data were preprocessed with FreeSurfer software and four cortical measures were extracted: cortical thickness (CT), surface area (SA), cortical volume (CV), and local gyrification index (LGI). We tested for both sex-specific and sex-nonspecific patterns of cortical anatomic alterations. Regardless of sex, individuals with MDD showed significantly higher LGI in posterior cortex relative to HCs. Significant sex-by-group interactions were observed, and subsequent post-hoc analyses revealed that female individuals with MDD showed significantly lower SA in left ventrolateral prefrontal cortex (vlPFC), lower CV in right rostromedial prefrontal cortex (rmPFC), and higher LGI in left visual cortex compared with sex-matched HCs, whereas the opposite patterns of significant effects were seen in male individuals with MDD relative to their sex-matched HCs. Thus, sex-nonspecific and specific morphometric differences from HCs were found in posterior cortex, while in PFC alterations were highly sex-specific early in the illness course. This may involve sex-specific alterations in brain development or processes related to illness onset. These findings highlight the presence and regional distribution of generalized as well as sex-specific alterations of brain neurobiology in MDD.

Disparities in Vision Impairment and Eye Diseases among Early Late-Life Women: The Study of Women's Health Across the Nation, Michigan Site

OBJECTIVE

To quantify the burden of vision impairment (VI) and ocular conditions among early late-life women.

METHODS

Women (n = 254, mean age 66.0 years) participated in a comprehensive vision assessment. Visual acuity (VA) and ocular disorders (diabetic retinopathy, macular degeneration, hypertensive retinopathy, glaucoma and cataracts) were defined clinically. Race, economic strain and education were self-reported.

RESULTS

The prevalence of presenting VI (VA 20/40 or worse) was 11.0% and 75% of that was correctable (best-corrected VI 2.8%). Black women and those with greater economic strain or less education had a higher prevalence of presenting VI. These disparities were no longer present after considering best-corrected VI. Ocular disease prevalence ranged from 3.3% (age-related macular degeneration) to 30.2% (hypertensive retinopathy), but most participants were unaware of their ocular diagnosis.

CONCLUSION

The discordance of presenting versus best-corrected VI and lack of knowledge of ocular conditions suggests a need for increased vision services. Access to optimal vision correction may attenuate differences across sociodemographic groups.

Conceptualizations of well-being in adults with visual impairment: A scoping review

Background

Despite its ubiquity, it is often not clear what organizations and services mean by well-being. Visual impairment (VI) has been associated with poorer well-being and well-being has become a key outcome for support and services for adults living with VI. A shared understanding of what well-being means is therefore essential to enable assessment of well-being and cross-service provision of well-being support.

Objectives

To provide an overview of the ways in which well-being has been conceptualized in research relating to adults living with VI.

Eligibility criteria

Articles were included in the review if the article discussed well-being in the context of adults living with VI, was available in English and as a full text.

Data sources

A systematic search using search terms relating to VI and well-being was conducted in EBSCOHost (Medline, CINHL) and Ovid (Embase Classic, Embase, Emcare 1995, Health + Psychosocial, HMIC Health Management Info, APA, PsycArticles, PsycInfo, PsycTests).

Charting

A team of three reviewers screened titles, abstracts and full-texts articles and extracted data. Ambiguous articles were referred to the research group and discussed.

Results

Of 10,662 articles identified in the search, 249 were included in the review. These referred to 38 types of well-being. The most common types were general well-being (n = 101; 40.6%) emotional well-being (n = 86, 34.5%) and psychological well-being (n = 66, 26.5%). Most articles (n = 150; 60.2%) referred to one type only, with a maximum of 9 listed in one article. A large number of articles did not clearly define well-being. A wide range of indicators of well-being related to the domains of hedonia, mood, positive and negative affect, quality of life, mental health, eudaimonia, self/identity, health, psychological reactions to disability and health problems, functioning, social functioning and environment, were extracted, many of which were used just once.

Conclusions

There remains a lack of consensus on how well-being is conceptualized and assessed in the context of adult VI. A standardized multi-domain approach derived with input from adults with VI and practitioners working with them is required to enable comparison of findings and cross-organizational provision of support.

Association of vision and hearing status with depressive symptoms among middle-aged and older Chinese adults

Objective

Long-term untreated vision and hearing impairments can negatively impact physical and mental wellbeing. We investigated the association of vision and hearing status with depressive symptoms among middle-aged and older Chinese adults.

Methods:

This was a prospective cohort study of 9,492 participants from the China Health and Retirement Longitudinal Study (CHARLS) carried out in 2011, 2013, 2015, and 2018. This study used self-reported vision and hearing status to determine the degree of impairment. Depressive symptoms were examined using the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10), with a total score of ≥ 12 indicating depressive symptoms. A Cox proportional hazards model adjusted for age, sex, residence, marital status, educational level, smoking history, alcohol consumption, hypertension, diabetes, heart disease, digestive disease, arthritis, wearing glasses, and hearing aids was used to estimate the association of vision and hearing status with depressive symptoms among middle-aged and older Chinese adults.

Results:

Of the 9,492 participants [mean (SD) age at CHARLS baseline, 58.12 (9.00) years], 3,238 (34.11%) participants reported incident depressive symptoms during the 7-year follow-up period. Participants who self-reported only vision impairment [hazard ratios (HR): 1.14, 95% confidence intervals (CI): 1.05–1.24], only hearing impairment (HR: 1.24, 95% CI: 1.06–1.46), and both vision and hearing impairments (HR: 1.25, 95% CI: 1.08–1.45) were independently associated with a greater increase in the hazard risk of incident depressive symptoms compared to those without vision and hearing impairments. An increase in participants' vision and hearing scores was associated with a significant increase in the hazard risk of incident depressive symptoms (HR: 1.04, 95% CI: 1.03–1.06).

Conclusion:

Vision and hearing status was associated with increased depressive symptoms among middle-aged and older Chinese adults during the 7-year follow-up period. Participants' use of glasses and hearing aids did not improve their depressive symptoms. Our findings may facilitate the development of effective treatments to prevent and treat vision and hearing impairments, thereby enhancing the physical and mental wellbeing of middle-aged and older adults.

Prevalence and Unmet Need for Mental Healthcare of Major Depressive Disorder in Community-Dwelling Chinese People Living With Vision Disability

Objective

Mental health services have been recognized as an essential part of the comprehensive eye care services, but data regarding the mental health of people living with vision disability (PLwVD) remain very limited. This study examined the epidemiology of major depressive disorder (MDD) among Chinese PLwVD, as well as their perceived needs for and utilization of mental health services.

Methods

By using stratified cluster sampling method, a total of 1,753 PLwVD were successfully recruited from 73 urban communities and 169 rural villages in Wuhan, China, and interviewed with the Mini-international Neuropsychiatric Interview 5.0. Standardized questions were used to measure perceived mental healthcare needs and use of mental health services of PLwVD with MDD.

Results

The one-month prevalence of MDD was 24.4%. Among the PLwVD with MDD, 26.0% perceived needs for mental healthcare and only 1.2% sought treatment from mental health specialists for their emotional problems. Factors associated with MDD were middle age [vs. young adulthood, odds ratio (OR) = 1.96, P < 0.001], older adulthood (vs. young adulthood, OR = 1.79, P = 0.004), being never-married (vs. married, remarried, and cohabiting, OR = 1.96, P < 0.001), being separated, divorced, and widowed (vs. married, remarried, and cohabiting, OR = 12.30, P < 0.001), a low level of objective social support (vs. high, OR = 1.83, P < 0.001), currently drinking (OR = 1.81, P < 0.001), having childhood-onset eye conditions (OR = 1.89, P = 0.005), and having difficulties in performing daily activities (OR = 2.78, P < 0.001).

Conclusions

Chinese PLwVD are at high risk for MDD and have a high level of unmet need for mental healthcare. Public strategies are warranted to improve the mental health literacy of PLwVD and make the mental health services available, accessible, and affordable for PLwVD.

Vision-Related Quality of Life and Seasonal Affective Disorder in Patients with Glaucoma and Macular Degeneration

Seasonal affective disorder (SAD) is characterized by depressive episodes related to changes in the seasons. Patients with severe vision loss are at an increased risk of SAD. This study seeks to determine the extent to which patients with moderate vision loss report symptoms of SAD. In this cross-sectional, comparative case series, the Seasonal Pattern Assessment Questionnaire (SPAQ) and the National Eye Institute Visual Function Questionnaire (VFQ-39) were used to screen 111 patients with age-related macular degeneration (AMD) and/or primary open-angle glaucoma (POAG). A multiple regression analysis was performed to create a predictive model for SAD based on the Global Seasonality Score (GSS) using the VFQ-39. Subjects who reported symptoms of SAD (GSS > 8) had lower vision-related quality of life (composite score: 57.2 versus 73.2, p < 0.001). Exploratory factor analysis revealed that the items on the VFQ-39 split into two distinct dimensions that together accounted for 63.2% of the total variance in the GSS. One group of questions addressed vision-related problems; the other group comprised questions related to the quality of life. Whereas this model successfully identified patients with vision loss at risk of SAD, a model restricted to the questions available on the shorter, widely used VFQ-25 instrument did not reliably identify patients at risk of SAD.

Depression secondary to vision loss in old age and an effective rapid screening tool for undiagnosed cases

BACKGROUND

Zenebe et al. recently stated that despite depression being a common mental health problem in the elderly population, it is underdiagnosed in over half of the cases (Zenebe et al. in Ann Gen Psychiatry, 2021). They described an extensive list of risk factors associated with geriatric depression. However, we noted that they did not include ophthalmic conditions in this list which have previously been identified as an important risk factor for depression in the elderly.

MAIN BODY

To determine the extent of undiagnosed anxiety and depression in our elderly population with vision loss, we screened a cohort of our patients, over 60 years with vision loss secondary to macular disease for both conditions. Our cohort included 104 patients with mean best corrected visual acuity 0.58 LogMAR (Snellen equivalent 6/24). In this group, we identified 29.8% (31/104) and 28.8% (30/104) of patients with at least one depression or anxiety-related symptom, respectively, in the past 2 weeks. We identified 7.7% (8/104) and 3.8% (4/104) who had significant symptoms of depression and anxiety, respectively, that warranted further follow-up. Only two of these patients had previously been diagnosed with anxiety or depression with the majority having no previous history of either condition. Patients from our cohort who screened for depression or anxiety often cited frustration completing tasks and loss of independence secondary to declining vision. They also complained that the vision loss resulted in a lack of confidence which in turn resulted in social isolation and loneliness. Most of the patients welcomed referral to their GP for follow-up for input regarding their mental health and they also stated an interest in attending hospital optometry low vision services and counselling support.

CONCLUSIONS

With increasing time pressures on healthcare services and the rising use of virtual clinics especially during the COVID-19 pandemic, it is still essential to screen efficiently for depression in those elderly patients who are at significant risk. There is a considerable burden of major depressive disease in the geriatric population, and we would recommend that physicians (Geriatricians, GPs, Ophthalmologists etc.) screen elderly patients with vision loss for depression using the rapid screening tool which we suggest.

Association of objective and subjective far vision impairment with perceived stress among older adults in six low- and middle-income countries

OBJECTIVES

To assess the association between far vision impairment (objective and subjective) and perceived stress among older adults from six low- and middle-income countries (LMICs, i.e., China, Ghana, India, Mexico, Russia, and South Africa).

METHODS

Data from the WHO Study on global AGEing and adult health were analyzed. Objective visual acuity was measured using the tumbling E LogMAR chart and was used as a four-category variable (no, mild, moderate, and severe visual impairment). Subjective visual impairment referred to difficulty in seeing and recognizing an object or a person across the road. Using two questions from the Perceived Stress Scale, a perceived stress variable was computed, and ranged from 0 (lowest stress) to 100 (highest stress). Multivariable linear regression with perceived stress as the outcome was conducted.

RESULTS

Data on 14,585 adults aged ≥65 years [mean (SD) age 72.6 (11.5) years; 55.0% females] were analyzed. Only severe objective visual impairment (versus no visual impairment) was significantly associated with higher levels of stress (b = 6.91; 95% CI = 0.94-12.89). In terms of subjective visual impairment, compared with no visual impairment, mild (b = 2.67; 95% CI = 0.56-4.78), moderate (b = 8.18; 95% CI = 5.84-10.52), and severe (b = 11.86; 95% CI = 9.11-14.61) visual impairment were associated with significantly higher levels of perceived stress.

CONCLUSIONS

This large study showed that far vision impairment was associated with increased perceived stress levels among older adults in LMICs. Increased availability of eye care services may reduce stress among those with visual impairment in LMICs, while more research is needed to better characterize the directionality of the far vision impairment-perceived stress relationship.

Visual impairment and depression in China: a 7-year follow-up study from national longitudinal surveys

OBJECTIVES

To explore the longitudinal association between visual impairment (VI) and depression among adults 45 years and older in China based on a nationally representative follow-up dataset.

SETTING

Participants in China from the China Health and Retirement Longitudinal Study were included.

PARTICIPANTS

A total of 6748 participants from two waves of the China Health and Retirement Longitudinal Study 2011-2018 were included for analysis by age group.

PRIMARY AND SECONDARY OUTCOME MEASURES

VI and depression were defined by self-diagnosis and the Center for Epidemiological Studies Depression Scale-10, respectively. Lagged dependent variable regression models with ordinary least squares estimation were used to evaluate the association between VI and depression. Age was divided into three groups, that is, 45-54, 55-64, and 65 years and older, to explore the relationship between VI and depression in different age groups.

RESULTS

In our study sample, VI remarkably predicted an increase in depressive scores. The magnitude of depressive scores increased among those with VI points greater than 3.517 (β=3.517; 95% CI=2.697 to 4.331) points than those without VI in the 7-year follow-up. Significant relationships were also found between VI and depression in the three age groups in the sensitivity analysis.

CONCLUSION

VI was associated with an increase in depression scores over a 7-year period. Female respondents, low educational attainment and high alcohol intake significantly predicted an increase in depressive status.
