Longitudinal Associations of Self-reported Vision Impairment With Symptoms of Anxiety and Depression Among Older Adults in the United States

Disparities in glaucoma and macular degeneration healthcare utilization among persons living with dementia in the United States

PURPOSE

Dementia is common among patients with primary open angle glaucoma (POAG) and neovascular age-related macular degeneration (nAMD). This study compares visit frequency, diagnostic test utilization, and treatment patterns for POAG and nAMD among persons with vs. without dementia.

METHODS

Optum's de-identified Clinformatics® Data Mart Database (January 1, 2000-June 30, 2022) was used for this study. Two cohorts were created from newly diagnosed POAG or nAMD patients. Within each cohort, an exposure cohort was created of newly diagnosed dementia patients. The primary outcome was the number of visits to an eye care provider. Secondary analyses for the POAG cohort assessed the number of visual field tests, optical coherence tomography (OCT), and glaucoma medication prescription coverage. The secondary analysis for the nAMD cohort included the number of injections performed. Poisson regression was used to determine the relative rates of outcomes.

RESULTS

POAG patients with dementia had reduced rates of eye care visits (RR 0.76, 95% CI: 0.75-0.77), lower rates of testing utilization for visual fields (RR 0.66, 95% CI: 0.63-0.68) and OCT (RR 0.67, 95% CI: 0.64-0.69), and a lower rate of glaucoma prescription medication coverage (RR 0.83, 95% CI: 0.83-0.83). nAMD patients with dementia had reduced rates of eye care visits (RR 0.74, 95% CI: 0.70-0.79) and received fewer intravitreal injections (RR 0.64, 95% CI: 0.58-0.69) than those without dementia.

CONCLUSIONS

POAG and nAMD patients with dementia obtained less eye care and less monitoring and treatment of their disease. These findings suggest that this population may be vulnerable to gaps in ophthalmic care.

Accelerometer-Measured Daily Behaviors That Mediate the Association Between Refractive Status and Depressive Disorders

Purpose

To identify the accelerometer-measured daily behaviors that mediate the association of refractive status with depressive disorders and enhance the understanding of behavioral differences in depression.

Methods

Participants with baseline mean spherical equivalent (MSE) and 7-day accelerometer measurements from the UK Biobank were included in this cohort study. Refractive status was categorized as hyperopia and non-hyperopia. Four daily behaviors, including moderate to vigorous intensity physical activity (MVPA), light physical activity (LPA), sedentary, and sleep were recorded between 2013 and 2015. We also assessed 24-hour behavior patterns. Depression cases were defined through both questionnaires and hospital records over 10 years of follow-up.

Results

Among 20,607 individuals, every 0.5-diopter increase in MSE was associated with a 6% higher risk of depressive disorders, with hyperopia participants at a higher risk than non-hyperopia participants (odds ratio, 1.14; 95% confidence interval, 1.05-1.23; P = 0.001). MVPA and sleep time significantly correlated with depressive disorders, with odds ratios of 0.79 and 1.14 (P < 0.05). MSE showed significant correlations with all four behaviors. The effects of MVPA and sleep duration on MSE and depressive disorders varied throughout the day. Mediation analyses showed that MVPA and sleep partially mediated the relationship between MSE and depressive disorders, with 35.2% of the association between moderate to high hyperopia and depression mediated by MVPA.

Conclusions

Physical activity and sleep significantly mediate the relationship between MSE and depressive disorders.

Translational Relevance

The mediation effect of MVPA highlights its therapeutic potential in reducing the risk of depression among individuals with moderate to severe hyperopia. Interventions aimed at increasing daytime MVPA and decreasing daytime sleep could enhance mental health in this vulnerable group.

Mental healthcare access among US adults with vision impairment and depression and/or anxiety symptoms

BACKGROUND

Although individuals with vision impairment are at greater risk for depression and anxiety, there has been limited study of mental healthcare utilization among this population.

OBJECTIVES

To address this gap, this pooled cross-sectional study estimates the prevalence of mental healthcare utilization among individuals with vision impairment during the COVID-19 pandemic.

METHODS

We calculated adjusted relative risk ratios and 95% confidence intervals of depression and/or anxiety symptoms and mental healthcare utilization using multinomial logistic regression, accounting for demographics, social determinants of health, and survey week. The population-based, U.S. Census Bureau Household Pulse Survey was administered April 2021-March 2022. Participants included 800,935 US adults (weighted population: 174,598,530) RESULTS: Adjusting for other factors, adults with vision impairment were more likely to report depression symptoms (RRR: 2.33; 95% CI: 2.03-2.68), anxiety symptoms (RRR: 2.12; 95% CI: 1.94-2.33, and comorbid depression and anxiety symptoms (RRR: 3.77; 95% CI: 3.51-4.04) compared with individuals with no vision impairment. Among individuals reporting anxiety or depression symptoms, individuals with vision impairment (RRR: 1.46; 95% CI: 1.35-1.59) were more likely to lack of mental healthcare utilization compared with individuals with no vision impairment.

CONCLUSION

Findings suggest that individuals with vision impairment are at increased risk for depression and/or anxiety symptoms and report reduced mental healthcare utilization compared with individuals without vision impairment. Additional programs and policies are needed to improve mental healthcare utilization among individuals with vision impairment and depression and/or anxiety symptoms, such as increased telehealth accessibility and coordination of behavioral health and ophthalmology services.

Concordance between Self-Reported Visual Difficulty and Objective Visual Impairment: The National Health and Aging Trends Study

PURPOSE

To examine the performance of self-reported visual difficulty (VD) in predicting objective visual impairment (VI) in older adults and explore factors that influence discordance.

DESIGN

Cross-sectional analysis of the National Health and Aging Trends Study (2022).

METHODS

Participants reporting blindness or difficulties with distance or near vision were characterized as having VD. Presenting binocular distance visual acuity (VA), near VA, and contrast sensitivity (CS) were assessed. Objective VI was defined as having VI in distance VA (worse than 20/40), near VA (worse than 20/40), or CS (worse than 1.55 logCS). Receiver operating characteristic analysis was used to compare performance of VD in predicting VI. To investigate factors that influence discordance, we limited our sample to adults with VI and used a multivariable logistic regression model to identify factors associated with not reporting VD. Similar analyses were performed to explore factors associated with reporting VD in adults without VI.

MAIN OUTCOME MEASURES

Discordance factors.

RESULTS

Four thousand nine hundred ninety-nine adults were included in the 2022 cohort. Visual difficulty achieved an area under the curve (AUC) of 56.0 (95% confidence interval [CI], 55.2-56.9) in predicting VI, with a sensitivity of 15.8 (95% CI, 14.2-17.5) and specificity of 96.3 (95% CI, 95.5-96.9). Characteristics associated with not reporting VD in adults with VI included female gender (odds ratio [OR], 0.64 [95% CI, 0.42-0.99]), Hispanic ethnicity (OR, 0.49 [95% CI, 0.31-0.78), higher income (≥75 000, OR, 1.99 [95% CI, 1.14-3.45]), ≥4 comorbidities (OR, 0.46 [95% CI, 0.29-0.72]), and depressive symptoms (OR, 0.49 [95% CI, 0.25-0.93]). Factors associated with self-reporting VD in the absence of VI included Hispanic ethnicity (OR, 2.11 [95% CI, 1.15-3.86]), higher income (≥$75 000, OR, 0.27 [95% CI, 0.12-0.63]), and anxiety symptoms (OR, 3.05 [95% CI, 1.56-5.97]).

CONCLUSIONS

Self-reported VD is a distinct measure assessing disability and has limited ability in predicting objective VI. Caution is advised when using self-reported VD as a surrogate measure for objective VI in epidemiological studies, although it may still be an effective way to capture risk of current or future disability.

Symptom patterns of comorbid depression and anxiety among older adults in China and their predictors

Comorbid depression and anxiety causes serious psychological and physiological damage for older people. This study aimed to identify heterogeneous classes of comorbid depression and anxiety (CDA) among older people in China and to ascertain predictors of latent class membership. Cross-sectional data of 10,919 cases were extracted from the Chinese Longitudinal Healthy Longevity Survey. Latent profile analysis (LPA) was used to identify symptom patterns of comorbid depression (measured by the 10-item Center for Epidemiologic Studies Depression Scale) and anxiety (measured by the Generalized Anxiety Disorder 7-item Scale). Multinomial logistic regressions following bivariate analyses were used to explore the relationship between the derived classes and individual- and social-level factors. Four patterns of CDA were identified: low symptoms of depression and anxiety (30.52%; n = 3333), mild depression only (53.26%; n = 5815), moderate depression and anxiety (13.82%; n = 1509), and severe depression and anxiety (2.40%; n = 262). Older people who are male, suffer from multimorbidity, and lack a healthy lifestyle are more likely to have problematic symptom profiles. While intimate relationships with partners and children significantly predicted CDA patterns, the effects of sibling relationships, daily life, and emotional support from the community were insignificant. LPA identified four distinct CDA patterns among a representative sample of older Chinese people. While restless sleep, lack of positive emotions, uselessness, and weak concentration are salient across all profiles, "difficult to relax" is prominent in profiles high in anxiety. In addition to individual-level variables, social-level factors, especially intimate relationships with partners and children rather than general links to siblings or the community, have unneglectable impacts on whether and to what extent older Chinese adults suffer from CDA in the cultural context of relationism, patriarchy, and filial piety.

Predictors and consequences of visual trajectories in Chinese older population: A growth mixture model

Background

Given the relatively high prevalence of vision impairment and the heterogeneity of visual changes among the elderly population, we aimed to identify the visual trajectories and to examine the predictors and consequences associated with each trajectory class.

Methods

We analysed data from 2235 participants involved in the 5th, 6th, 7th, and 8th waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), where vision impairment was evaluated using an adapted Landolt-C chart during each wave. We employed a growth mixture model (GMM) to identify distinct visual trajectories and logistic regression analysis to examine the predictors associated with each trajectory class. Furthermore, we investigated the effect of visual trajectories on distal consequences, including cognitive function, activities of daily living (ADL), instrumental activities of daily living (IADL), depression, anxiety, and fall risk. Within the CLHLS study, cognitive function was assessed using the Chinese version of the Mini-Mental State Examination (CMMSE), ADL via the Katz index, and IADL through a modified version of Lawton's scale. Lastly, depression was assessed using the 10-item version of the Centre for Epidemiologic Studies (CES-D-10), while anxiety was measured using the Generalized Anxiety Disorder scale (GAD-7). Fall risk was determined by asking the question: 'Have you experienced any falls within the past year?'

Results

We identified two distinct visual trajectories in our analysis. Most older adults (n = 1830, 81.9%) initially had a good vision level that diminished ('high-baseline decline' group). Conversely, the remaining participants (n = 405, 18.1%) initially had a lower vision level that improved over time ('low-baseline improvement' group). The 'high-baseline decline' group was more likely to include older adults with relatively higher body mass index (BMI) (odds ratio (OR) = 1.086; 95% confidence interval (CI) = 1.046, 1.127), individuals with higher formal educational qualifications (OR = 1.411; 95% CI = 1.068, 1.864), those current engaging in exercise (OR = 1.376; 95% CI = 1.046, 1.811), and individuals reporting more frequent consumption of fruit (OR = 1.357; 95% CI = 1.053, 1.749). Conversely, the 'low-baseline improvement' group had a higher likelihood of including older individuals (OR = 0.947; 95% CI = 0.934, 0.961), residents of nursing homes (OR = 0.340; 95% CI = 0.116, 0.993) and those self-reporting cataracts (OR = 0.268; 95% CI = 0.183, 0.391) and glaucoma (OR = 0.157; 95% CI = 0.079, 0.315). Furthermore, the 'high-baseline decline' group showed a positive impact on distal consequences, adjusting for sex, birthplace, residence, main occupation, education, economic status, and marital status. This impact included cognitive function (correlation coefficient (β) = 2.092; 95% CI = 1.272, 2.912), ADL (β  = -0.362; 95% CI = -0.615, -0.108), IADL (β  = -1.712; 95% CI = -2.304, -1.121), and reported lower levels of depression (β  = 0.649; 95% CI = 0.013, 1.285). We observed no significant influence on fall risk and anxiety within the identified visual trajectories in the adjusted model.

Conclusions

Vision in older adults with ocular disease could potentially be improved. Having formal education, maintaining an appropriate BMI, engaging in exercise, and consuming fruit more frequently appear to be beneficial for the visual health of the elderly. Considering the negative impact of visual impairment experience on distal cognition, self-care ability, and depression symptoms, stakeholder should prioritise long-term monitoring and management of vision impairment among older adults.

A Prospective Association Between Sensory Impairment and Cognitive Performance Among Older Community-Dwelling Adults: The Role of Depressive Symptoms

We examined whether vision impairment (VI) and hearing impairment (HI) and dual sensory impairment (DSI) affect cognitive performance and whether depression mediates that effect. We examined 55,340 participants from the Survey of Health, Aging and Retirement in Europe, which assessed 32,325 participants in 2011 (baseline, Time 1), 2015 (follow-up, Time 2), sociodemographic data and health factors, self-reported VI, HI, and DSI at baseline, depression, and cognitive performance after four years. A multiple mediator model was tested using bootstrapping and resampling. At baseline, 22.9% had VI, 10.2% HI, and 10.4% had DSI. We found a significant negative association between VI (b = -0.023, p = .001) and DSI (b = -0.083, p = .001) and cognitive performance; both were also associated with depression, which was linked with poor cognition. VI or DSI among older adults are associated with poor cognitive function directly and indirectly by increasing depression symptoms.

Association between visual impairment and suicide: A systematic review and meta-analysis

Visual impairment severely impacts the life of the patients. In this study, we systematically reviewed studies on the potential relationship between visual impairment and suicidal behaviour, and conducted meta-analyses on the risk estimates. We searched 11 literature databases on 20 October 2022 and identified a total of 10 eligible studies with 5.8 million participants. Suicide behaviour was investigated according to three domains: suicide ideation, suicide attempt and suicide death. In the 10 eligible studies, seven reported data on suicide ideation, five reported data on suicide attempt, and three reported data on suicide death. All summary estimates extracted for use in the meta-analyses were adjusted estimates of association since we acknowledged that depression as well as other confounding factors may play an important role. We found that visual impairment was a significant risk factor of suicide ideation (OR 1.83; 95% CI: 1.40-2.40; p = 0.000012), suicide attempt (OR 2.62; 95% CI: 1.29-5.31; p = 0.0077) and suicide death (OR 7.00; 95% CI: 2.30-21.4; p = 0.000063). These high increases in risk of suicide from visual impairment underscore the importance of eye health on the overall mental health, and the potential devastating consequences of insufficient access to eye care, lack of treatment possibilities for any reason or low political priority of eye care.

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.

Predictors of Job Retention After Onset of Visual Impairment in Late Middle Age

Objectives: We investigated factors associated with job retention after developing a visual impairment in late middle adulthood. Methods: Using longitudinal survey data from the Health and Retirement Study, we identified respondents who first reported poor eyesight or legal blindness at age 44-64 years in Waves 3-14 and who were employed in the previous wave. We conducted a multiple logistic regression analysis with job retention as the dependent variable and health and socioeconomic characteristics as independent variables. Results: Women, people who were married or partnered, and people with fair or better self-reported health were more likely to retain employment after vision loss, whereas people with more chronic health conditions were less likely to retain employment. Discussion: Poor health and chronic health conditions may prompt late middle-aged adults to leave the labor force after developing vision loss. Timely vocational rehabilitation services can help employed people with vision loss retain employment.

Vision Impairment and Psychosocial Function in US Adults

Importance

Vision impairment and psychosocial function, including symptoms of depression and anxiety and social isolation, are a major cause of morbidity in the US. However, there is a lack of nationally representative studies assessing associations between both objective and subjective vision impairment with psychosocial function following the COVID-19 pandemic.

Objective

To provide updated national estimates on the associations of vision impairment with depressive and anxiety symptoms and social isolation in US adults 65 years and older.

Design, Setting, and Participants

This was a cross-sectional analysis of the National Health and Aging Trends Study round 9 (2019) and 11 (2021), a nationally representative sample of Medicare beneficiaries aged 65 years and older. Binocular distance visual acuity, near visual acuity, and contrast sensitivity were tested. Objectively measured vision impairment was defined as having vision impairment in either distance visual acuity (worse than 20/40), near visual acuity (worse than 20/40), or contrast sensitivity (worse than 1.55 logCS). Self-reported vision impairment was defined based on participants' report on their vision status. Data were analyzed in May 2023.

Main Outcomes and Measures

Depressive and anxiety symptoms assessed via the Patient Health Questionnaire. Social isolation was defined based on living arrangement, communication frequency, and activity participation responses.

Results

Among 2822 community-dwelling adults sampled from a population of 26 182 090, the mean (SD) age was 78.5 (5.6) years; 1605 individuals (54.7%) were female; 1077 (32.3%) had objectively measured vision impairment, and 203 (6.4%) had self-reported vision impairment. In adjusted models, all outcomes were significantly associated with objectively measured vision impairment, including depressive symptoms (odds ratio [OR], 1.81; 95% CI, 1.26-2.58), anxiety symptoms (OR, 1.74; 95% CI, 1.13-2.67), and severe social isolation (OR, 2.01; 95% CI, 1.05-3.87). Similarly, depressive symptoms (OR, 2.37; 95% CI, 1.44-3.88) and anxiety symptoms (OR, 2.10; 95% CI, 1.09-4.05) but not severe social isolation symptoms (OR, 2.07; 95% CI, 0.78-5.49) were significantly associated with self-reported vision impairment.

Conclusions and Relevance

In this study, vision impairment was associated with several psychosocial outcomes, including symptoms of depression and anxiety and social isolation. These findings provide evidence to support prioritizing research aimed at enhancing the health and inclusion of people with vision impairment.

The association between cataract surgery and mental health in older adults: a review

BACKGROUND

Although cataract surgery has been proposed as a potentially modifiable protective factor for enhancing emotional well-being in cataract patients, studies examining the relationship between anxiety or depression and cataract surgery have yielded inconsistent findings. This review summarizes existing evidence to establish whether cataract surgery is associated with depression and anxiety in older adults.

METHODS

A literature search was conducted across PubMed, Medline, Web of Science, and Embase databases. An initial screening by abstracts and titles was performed, followed by a review and assessment of the methodological quality of the relevant full papers, and final inclusion of 44 studies were deemed eligible for inclusion in this review.

RESULTS

Among 44 included studies, 36 studies (81.8%) were observational studies concerning the association of cataract surgery or cataracts with anxiety or depression, four studies (9.1%) were interventional studies, and four studies (9.1%) were reviews. Cataract surgery notably enhances the mental health of individuals with impaired vision. However, the multifaceted nature of psychological well-being, influenced by various factors, suggests that cataract surgery may not address all aspects comprehensively. Additionally, preoperative anxiety and depression significantly impact cataract surgery outcomes.

CONCLUSION

Vision impairment in older adults is closely associated with increased symptoms of depression and anxiety. While surgical intervention for cataracts improves these symptoms, it might be less effective for mental disorders with multifactorial causes. Notably, anxiety or depression poses challenges to successful preoperative and intraoperative cataract surgeries.

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.

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.

The association between visual impairment and mental disorders

To determine the association between visual impairment (VI) and some mental disorders using the general health questionnaire (GHQ) in individuals aged 60 years and above in Tehran, Iran. The present population-based cross-sectional study was conducted on people aged 60 and older in Tehran, Iran using multi-stage cluster sampling. After selecting the samples, examinations including visual acuity measurement, refraction, and slit-lamp biomicroscopy were performed for all participants. The GHQ was used to examine mental disorders. Simple and multiple linear regressions were used to investigate the association between VI and mental disorders. Of the 3740 invitees, 3310 participated in the study (response rate: 88.50%). After applying the exclusion criteria, 2789 individuals were analyzed for this report. Mean score of physical, anxiety, social and depression disorders in people with and without VI was 3.74 ± 2.03, 5.81 ± 2.79, 7.56 ± 1.91, 1.32 ± 1.90, and 3.14 ± 1.76, 4.93 ± 2.71, 8.09 ± 1.99, 0.91 ± 1.38, respectively. The total score of GHQ in participants with and without VI was 18.43 ± 4.75 and 17.07 ± 4.19, respectively. The association between GHQ subscales and total GHQ score with VI by multiple linear regression showed that VI had a statistically significant direct association with physical symptoms (β = 0.37; 95% CI 0.12 to 0.62) and anxiety (β = 0.48; 95% CI 0.16 to 0.81). Nevertheless, depression had a borderline association with VI (β = 0.21; 95% CI - 0.03 to 0.45) and social dysfunction did not have a statistically significant association with VI in the final linear regression model and did not remain in the model. Total GHQ score had a statistically significant association with VI (β = 1.02; 95% CI 0.39 to 1.64) in the presence of covariates. Regarding the association between VI and GHQ components, the physical symptoms had the highest R2 (R2 = 0.159). Patients with VI suffer more from anxiety, depression, and physical symptoms regardless of age, sex, education, and other effective variables. The coincidence of aging with VI and the association of VI with mental disorders emphasizes the importance of a broader view of the elderly and the aging process.

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.

Treated unruptured cerebral aneurysm in elderly patients: a single center study

INTRODUCTION

The increase in life expectancy raises the question of the treatment of unruptured intracranial aneurysms in extremely old patients (>80 years). We present results in terms of occlusion and complications in both symptomatic and asymptomatic aneurysm.

METHODS

All patients aged >80 years admitted to the Foundation Adolphe de Rothschild between January 1, 2005 and March, 2023 were included. Aneurysms were grouped as compressive and non-compressive. Procedural complications were grouped as symptomatic (i.e., leading to any temporary or permanent neurological deficit) and severe (defined by modified Rankin Scale (mRS) ≥3 at follow-up).

RESULTS

Forty-two aneurysms were treated in the study period. Coiling (with or without remodeling) was the treatment of choice in 30 patients. Eighteen patients had compressive aneurysm. Six complications occurred (14.2%), all ischemic. The majority of complications occurred in symptomatic aneurysms, in 4 patients (66.6%). One of the patients treated by flow-diverter had severe complications (mRs ≥3) with hemiplegia.

CONCLUSION

In extremely specific cases, treatment of unruptured aneurysm in people older than 80 years may be considered. Compressive aneurysm is associated with a high risk of complications. Treatments can be endovascular. Further prospective studies are required to confirm this hypothesis.

Dynamic associations between vision and hearing impairment and depressive symptoms among older Chinese adults

BACKGROUND

Whether the impact of vision impairment (VI)/hearing impairment (HI) on depressive symptoms changes over time has not been investigated. This study aimed to examine the complex dynamic associations between VI/HI and depressive symptoms to design effective prevention strategies for older Chinese adults.

METHODS

Data were from the China Health and Retirement Longitudinal Study (CHARLS). The study identified self-reported VI, HI, depressive symptoms, and other covariates (including social isolation). Logistic regression models were used to analyze the dynamic associations across three waves, with the assessment of multiplicative and additive interactions.

RESULTS

Of the 8519 participants in wave 1 (mean [SD] age, 62.0 [8.0] years, 49.5 % male), 38.5 % had depressive symptoms. After adjusting for covariates including social isolation, VI and HI were significantly associated with depressive symptoms across all three waves. Specifically, the adjusted odds ratio (AOR) of VI increased from 2.08 (95 % CI: 1.89 to 2.29) in wave 1 to 2.15 (95 % CI: 1.90 to 2.44) in wave 3; while the AOR of HI increased from 1.80 (95 % CI: 1.58 to 2.04) in wave 1 to 2.11 (95 % CI: 1.75 to 2.51) in wave 3. The additive interactions between VI and HI on depressive symptoms in each wave (e.g., RERI [95 % CI]: 7.90 [2.51 to 12.30] in wave 1) were significant without adjusting for social isolation.

CONCLUSION

The study suggests that VI and HI are consistently associated with depressive symptoms among older adults in China over a four-year period, and their influences on mental health deserve more attention.

Characteristics associated with blindness or visual impairment within the adolescent demographic: a national cohort analysis

BACKGROUND

Psychosocial metrics associated with self-reported blindness or visual impairment for adolescents in the National Survey of Drug Use and Health (NSDUH) have not been fully characterized. This retrospective cohort analysis of the latest NSDUH aimed to determine novel characteristics associated with self-reported visual loss among adolescents in the United States.

METHODS

Data from the NSDUH2020, a publicly available, federally validated database, were analyzed. Self-reported severe visual impairment or blindness was defined as being truly blind or having serious difficulty seeing even when wearing corrective lenses (s-rSVI). Inclusion criteria were all cases of s-rSVI in adolescents aged 12-17 years. NSDUH weights were used to accommodate complex survey design, nonresponse rates, and population variance. Weighted percentages, asymptotic two-sided Rao-Scott χ2 analyses, and multivariable logistic regression were performed. Statistical significance was considered reached at P < 0.05.

RESULTS

A total of 5,667 adolescents aged 12-17 years were surveyed, and s-rSVI occurred in 236 cases (weighted percentage, 3.48%). Within our final multivariable risk model, characteristics associated with increased odds of s-rSVI were female sex, Asian and Latino race/ethnicity (relative to non-Hispanic White), and self-reported serious difficulty hearing and concentrating (all P < 0.05).

CONCLUSIONS

This national retrospective cohort analysis highlights risk factors associated with s-rSVI for adolescents within the 2020 NSDUH. Clinicians and policymakers should consider at-risk demographics for s-rSVI during development and enhancement of screening programs, population health initiatives, and healthcare policy issues.

Association of hyperopia with incident clinically significant depression: epidemiological and genetic evidence in the middle-aged and older population

AIMS

To investigate the association between hyperopia and clinically significant depression (CSD) in middle-aged and older individuals. The effect of genetic determinants of hyperopia on incident CSD was also explored.

METHODS

We included participants who had available data on mean spherical equivalent (MSE) and were free of depression at baseline from the UK Biobank. For the phenotypic association, hyperopia was defined as MSE of+2.00 dioptres (D) or greater, and was divided into mild, moderate and high groups. Diagnosis of CSD across follow-up was determined based on electronic hospital inpatients records. For the genetic association analysis, the association between hyperopia Polygenic Risk Score and incident CSD was assessed. Mendelian randomisation was assessed for causality association.

RESULTS

Over a median follow-up of 11.11 years (IQR: 10.92-11.38), hyperopia was significantly associated with incident CSD independent of genetic risk (HR 1.29, 95% CI 1.05 to 1.59) compared with emmetropia participants, especially in those hyperopic patients without optical correction (HR 1.38, 95% CI 1.07 to 1.76). In addition, participants in the high degree of hyperopia were more likely to have incident CSD than participants in the mild degree of hyperopia (P for trend=0.009). Genetic analyses did not show any significant associations between hyperopia and incident CSD (p≥0.1).

CONCLUSIONS

Hyperopia was significantly associated with an increased risk of incident CSD. This was independent of genetic predisposition to hyperopia, emphasising the importance of regular vision screening and correction of hyperopia to reduce the risk of CSD regardless of genetic risk.

Longitudinal associations between self-reported vision impairment and all-cause mortality: a nationally representative cohort study among older Chinese adults

OBJECTIVE

To compare the effects of pre-existing and new self-reported vision impairment (VI), and its correction, on all-cause mortality among Chinese adults aged 45 years and older.

METHODS

We used four waves of data from the China Health and Retirement Longitudinal Study. Our analytical cohort consists of 15 808 participants aged 45 years and older with an average follow-up of 6.4 years. Exposures included pre-existing self-reported VI and vision correction (time-independent exposures), new self-reported VI and vision correction (time-dependent exposures). Outcomes were measured as the risk of all-cause mortality and the risk stratification for pre-specified factors.

RESULTS

Compared with participants with normal vision, all-cause mortality was higher among those with pre-existing self-reported VI (crude HR (cHR)=1.29, 95% CI: 1.17 to 1.44; adjusted HR (aHR)=1.22, 95% CI: 1.09 to 1.37) and new self-reported VI (cHR=1.42, 95% CI: 1.28 to 1.58; aHR=1.36, 95% CI: 1.21 to 1.51). Mortality risk was lower among those with high school or higher education. Participants who were wearing eyeglasses/contact lenses or had cataract surgery at baseline did not have significantly higher all-cause mortality (eyeglasses: aHR=0.82, 95% CI: 0.65 to 1.02; cataract surgery: aHR=1.12, 95% CI: 0.74 to 1.69) compared with participants with normal vision. The same was true among participants with new correction of self-reported VI (glasses: aHR=1.01, 95% CI: 0.78 to 1.24; cataract surgery: aHR=0.95, 95% CI: 0.68 to 1.31).

CONCLUSIONS

Both pre-existing and new self-reported VI increase all-cause mortality among Chinese adults aged 45 years and older, though visual correction reduces this risk.

Associations between vision impairment and multimorbidity among older Chinese adults: results from the China health and retirement longitudinal study

BACKGROUND

Although several studies have reported the relationship between vision impairment (VI) and multimorbidity in high-income countries, this relationship has not been reported in low- and middle-income countries. This study aimed to explore the relationship between VI with multimorbidity and chronic conditions among the elderly Chinese population.

METHODS

The cross-sectional analysis was applied to data from the China Health and Retirement Longitudinal Study (CHARLS) in 2018. A total of 8,108 participants ≥ 60 years old were included, and 15 chronic conditions were used in this study. Logistic regression analysis was used to analyze the relationship between VI with multimorbidity and chronic conditions.

RESULTS

The prevalence of 15 chronic conditions and multimorbidity was higher among the elderly with VI than those without VI. After adjusting for demographic and socioeconomic confounders, 10 chronic conditions were associated with VI (all P < 0.05). Furthermore, positive association was observed between VI and one (odds ratio [OR]: 1.52; 95% confidence intervals [95%CI]: 1.16-2.00; P = 0.002), two (OR: 2.09; 95%CI: 1.61-2.71; P < 0.001), three (OR: 2.87; 95%CI: 2.22-3.72; P < 0.001), four (OR: 3.60; 95%CI: 2.77-4.69; P < 0.001), and five or more (OR: 5.53; 95%CI: 4.32-7.09; P < 0.001) chronic conditions, and the association increased as the number of chronic conditions (P for trend < 0.001). Sensitivity analysis stratified by gender, education, smoking status, and annual per capita household expenditure still found VI to be positively associated with multimorbidity.

CONCLUSIONS

For patients older than 60 years, VI was independently associated with multimorbidity and various chronic conditions. This result has important implications for healthcare resource plans and clinical practice, for example, increased diabetes and kidney function screening for patients with VI.

Prevalence of depression, anxiety and suicidal ideas and associated factors, in particular sensory impairments, in a population of Bashkortostan in Russia

To assess prevalence and associated factors of depression, anxiety and suicidal ideas in populations from Russia, we conducted in rural and urban regions in Bashkortostan/Russia two population-based studies (Ural Eye and Medical Study (UEMS), performed from 2015 to 2017; Ural Very Old Study (UVOS), performed from 2017 to 2020) which included participants aged 40 + years and 85 + years, respectively. Depression was assessed using the questionnaire of the Center for Epidemiologic Studies Depression Scale Scoresheet, and anxiety was examined applying the State Trait Inventory Anxiety Test. Suicidal ideas were explored by the question whether suicide had previously been thought of or attempted (and if yes, for what reasons). In the statistical analysis we assessed the mean of the main outcome parameter (depression score and anxiety score) and searched for associations between these parameters and other parameters in univariable and multivariable regression analyses. In the UEMS with 5893 individuals (age: 59.0 ± 10.7 years; range 40-94 years), higher depression score and anxiety score were associated (multivariable analysis) with more marked hearing loss (beta: 0.07; P < 0.001, and beta: 0.07; P < 0.0012, respectively) and worse visual acuity (beta: 0.04; P = 0.02; and beta: 0.03; P = 0.03, resp.), in addition to female sex, Russian ethnicity, lower educational level, less alcohol consumption, weaker hand grip strength, less physical activity, and higher prevalence of dry eye disease. Attempted suicide was reported by 88 (1.5%; 95% CI 1.2, 1.8) participants. Having thought of suicide within the last 6 months was reported by 63 (1.1%) individuals. Out of 1491 UVOS participants (age: 88.2 ± 2.8 years; range 85-100 years) with a mean depression score of 20.0 ± 10.3 (median 18; range 0-58), 916 (61.4%; 95% CI 59.0, 63.9) fulfilled the definition of depression (depressions core ≥ 16). Higher depression score and higher anxiety score correlated (multivariable analysis) with higher hearing loss score (beta: 0.07; P = 0.02, and beta: 0.08; P = 0.009, resp.) and worse visual acuity (beta: 0.13; P < 0.001, and beta: 0.09; P = 0.007, resp.), in addition to female sex, urban region, less physical activity, less fruit intake, and lower cognitive function. Overall, 15 (1.0%; 95% CI 0.50, 1.50) individuals had attempted or thought of suicide. In conclusion, the findings suggest that besides female sex, lower level of education and lower cognitive function, it was sensory impairment, namely vision and hearing impairment, which belonged to the determinants of depression and anxiety in these populations from Russia.

Hand grip strength and ocular associations: the Ural Eye and Medical Study

PURPOSE

To explore the associations between hand grip strength (HGS) and ocular parameters and diseases.

DESIGN

Population-based cohort study.

METHODS

Participants of the Ural Eye and Medical Study, including 5899 (80.5%) out of 7328 eligible individuals aged 40+ years, underwent systemic and ophthalmological examinations including dynamometric HGS measurement.

RESULTS

The study included 5381 (90.4%) individuals (age: 58.6±10.6 years; range: 40-94 years) with HGS measurements. Higher HGS (mean: 30.6±11.7 dekaNewton) correlated (multivariable analysis) with better visual acuity (beta: 0.02, p=0.02), longer ocular axial length (beta: 0.03, p=0.003), higher intraocular pressure (beta: 0.03, p=0.001), thicker peripapillary retinal nerve fibre layer (beta: 0.03, p=0.001) and lower prevalence of diabetic retinopathy (beta: -0.03, p=0.007), after adjusting for younger age, male sex, Russian ethnicity, higher body height and waist to hip ratio, higher educational level, higher physical total score, lower smoking package years, higher serum concentration of haemoglobin, higher prothrombin index, lower leucocyte cell count, lower prevalence of non-alcoholic fatty liver disease, lower depression score and lower prevalence of arthritis. In the model, HGS was not correlated with prevalence of nuclear cataract (p=0.38), cortical cataract (p=0.67), subcapsular posterior cataract (p=0.50), open-angle glaucoma (p=0.22) or angle-closure glaucoma (p=0.27).

CONCLUSIONS AND RELEVANCE

In addition to parameters such as lower physical activity, higher depression score and worse general health status, a reduced HGS is associated with visual impairment, shorter axial length, lower intraocular pressure, thinner peripapillary retinal nerve fibre layer and higher prevalence of diabetic retinopathy. HGS dynamometry or a handshake may provide the ophthalmologist additional clinical information about the general health and ocular parameters of the patient.

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.

Impacts of regular consumption of grapes on macular pigment accumulation in Singapore older adults: a randomized controlled trial

Background: Oxidative stress is a key risk factor for visual impairment and consuming dietary antioxidant-rich foods may help in managing visual impairments. However, a limited number of studies have investigated the effect of dietary antioxidant-rich food including grapes on eye health in older adults. Objectives: To assess the effects on macular pigment accumulation of regular consumption of grapes in Singapore older adults. Methods: This was a 16 week, double-blind, randomized, placebo-controlled trial. Thirty-four Singapore older adults were randomized into regularly consuming either 46 g day-1 of freeze-dried table grape powder (the intervention group) or the same amount of placebo powder (the control group). Macular pigment optical density (MPOD), skin carotenoid status, advanced glycation end product (AGEs) status and dietary lutein intake were assessed every 4 weeks, and plasma lutein concentration, total antioxidant capacity and total phenolic content were measured every 8 weeks. Results: A significant time effect (p = 0.007) was observed for MPOD, and this is largely attributed to the improvement in the MPOD for the intervention group, as a significant increase was observed only in this group (week 0: 0.56 ± 0.04 D.U.; week 16: 0.61 ± 0.04 D.U., p < 0.01). Additionally, a significant increase in plasma total antioxidant capacity (week 0: 0.26 ± 0.13 mM TEAC; week 16: 0.36 ± 0.20 mM TEAC, p < 0.01) and total phenolic content (week 0: 10.50 ± 0.44 mg L-1 GAE; week 16: 12.58 ± 0.55 mg L-1 GAE, p < 0.001) was observed for the intervention group only. In contrast, a significant increase in skin AGE status was observed in the control group (week 0: 2.47 ± 0.24; week 16: 2.99 ± 0.12, p < 0.05) while this was mitigated in the intervention group. There were no differences in dietary lutein intake, plasma lutein concentration and skin carotenoid status between groups throughout the study. Conclusions: Regular intake of grapes may improve eye health in Singapore older adults, specifically in augmenting MPOD, which can be explained by an increase in plasma total antioxidant capacity and phenolic content, and the downregulation of AGEs. This study was registered at clinicatrials.gov as NCT05064865.

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.

The interaction between instrumental activities of daily living and dual sensory function on cognition among the elderly in China: A cross-sectional survey

To explore the interaction of instrumental activities of daily living (IADLs) and dual sensory function on cognition in the elderly. A cross-sectional survey was conducted in six general hospitals in China, from October 2022 to December 2022. Data collection included general information, IADLs scale, self-reported sensory function questionnaire, and mini-mental state examination (MMSE). Binary logistic regression was used to examine the association between factors and cognition. The interactive effect was evaluated by synergy index (S), relative excess risk due to interaction (RERI), and attributable proportion due to interaction (AP). The odds ratio (OR) of IADLs decline in cognition is 4.412 (95% confidence interval [CI]: 3.633-5.358, p < 0.001); the OR of dual sensory difficulty on cognition is 2.502 (95% CI: 1.272-4.921, p = 0.008). The OR of interaction between IADLs decline and dual sensory difficulty on cognition is 13.737 (95% CI: 9.726-19.400, p < 0.001). RERI (95% CI) = 7.823 (3.230-12.417), AP (95% CI) = 0.570 (0.392-0.747), S (95% CI) = 2.593 (1.616-4.160). IADLs decline and dual sensory difficulty are associated with cognitive decline. IADLs decline and dual sensory difficulty have interaction with cognitive decline; the interaction is greater than the sum effect of those two on cognitive decline independently. Sensory and IADLs assessment can be used as early screening items for cognition among the elderly. In addition, protecting sensory function and maintaining IADLs in the elderly can help protect their cognition.

Concurrent hearing and vision impairment and 8-year memory decline in community-dwelling older adults

BACKGROUND

Hearing and vision impairments are risk factors for cognitive decline; less is known about dual sensory impairment. This study quantifies the association between dual sensory impairment and 8-year change in memory among older adults.

METHODS

Data (N = 5552) were from the National Health and Aging Trends Study. Memory (immediate/delayed word recall, subjective memory) was measured annually (2011 to 2019). Hearing and vision impairments were measured by self-report. Association between dual sensory impairment and 8-year change in memory was assessed using multivariate linear mixed effect models and generalized logistic mixed models.

RESULTS

Rate of memory decline was most accelerated among participants with dual sensory impairment. For example, 8-year decline in delayed word recall was -1.03 (95% confidene interval: -1.29, -0.77) for dual sensory impairment versus -0.79 (-0.92, -0.67) for single and -0.56 (-0.63, -0.48) for no impairment.

CONCLUSION

Older adults with dual sensory impairment may be at particularly higher risk for cognitive decline.

Positive feedback loop between vision-related anxiety and self-reported visual difficulty

BACKGROUND

Patients with Inherited Retinal Diseases typically experience progressive, irreversible vision loss resulting in low vision and blindness. As a result, these patients are at high risk for vision-related disability and psychological distress, including depression and anxiety. Historically, the relationship between self-reported visual difficulty (encompassing metrics of vision-related disability and quality of life, among others) and vision-related anxiety has been regarded as an association and not a causal relationship. As a result, there are limited interventions available that address vision-related anxiety and the psychological and behavioral components of self-reported visual difficulty.

MATERIALS AND METHODS

We applied the Bradford Hill criteria to evaluate the case for a bidirectional causal relationship between vision-related anxiety and self-reported visual difficulty.

RESULTS

There is sufficient evidence to satisfy all nine of the Bradford Hill criteria of causality (strength of association, consistency, biological gradient, temporality, experimental evidence, analogy, specificity, plausibility, and coherence) for the relationship between vision-related anxiety and self-reported visual difficulty.

CONCLUSIONS

The evidence suggests that there is a direct positive feedback loop-a bidirectional causal relationship-between vision-related anxiety and self-reported visual difficulty. More longitudinal research on the relationship between objectively-measured vision impairment, self-reported visual difficulty, and vision-related psychological distress is needed. Additionally, more investigation of potential interventions for vision-related anxiety and visual difficulty is needed.

Measuring visual information gathering in individuals with ultra low vision using virtual reality

People with ULV (visual acuity ≤ 20/1600 or 1.9 logMAR) lack form vision but have rudimentary levels of vision that can be used for a range of activities in daily life. However, current clinical tests are designed to assess form vision and do not provide information about the range of visually guided activities that can be performed in daily life using ULV. This is important to know given the growing number of clinical trials that recruit individuals with ULV (e.g., gene therapy, stem cell therapy) or restore vision to the ULV range in the blind (visual prosthesis). In this study, we develop a set of 19 activities (items) in virtual reality involving spatial localization/detection, motion detection, and direction of motion that can be used to assess visual performance in people with ULV. We estimated measures of item difficulty and person ability on a relative d prime (d') axis using a signal detection theory based analysis for latent variables. The items represented a range of difficulty levels (- 1.09 to 0.39 in relative d') in a heterogeneous group of individuals with ULV (- 0.74 to 2.2 in relative d') showing the instrument's utility as an outcome measure in clinical trials.

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.

Advances in transcorneal electrical stimulation: From the eye to the brain

The mammalian brain is reported to contain about 10⁶-10⁹ neurons linked together to form complex networks. Physiologically, the neuronal networks interact in a rhythmic oscillatory pattern to coordinate the brain's functions. Neuromodulation covers a broad range of techniques that can alter neuronal network activity through the targeted delivery of electrical or chemical stimuli. Neuromodulation can be used to potentially treat medical conditions and can serve as a research tool for studying neural functions. Typically, the main method of neuromodulation is to electrically stimulate specific structures in both the central and peripheral nervous systems via surgically implanted electrodes. Therefore, it is imperative to explore novel and safer methods for altering neuronal network activity. Transcorneal electrical stimulation (TES) has rapidly emerged as a non-invasive neuromodulatory technique that can exert beneficial effects on the brain through the eyes. There is substantial evidence to show that TES can change the brain oscillations in rodents. Moreover, the molecular data clearly shows that TES can also activate non-visual brain regions. In this review, we first summarize the use of TES in the retina and then discuss its effects in the brain through the eye-brain connection. We then comprehensively review the substantial evidence from electrophysiological, behavioral, and molecular studies on the role of TES on modulating neurons in the brain. Lastly, we discuss the implications and possible future directions of the research on TES as a non-invasive tool for neuromodulation of the brain via directly stimulating the mammalian eye.

Associations of dual sensory impairment with long-term depressive and anxiety symptoms in the United States

OBJECTIVE

We explored the associations of dual sensory impairment (DSI) with long-term depressive and anxiety symptoms as well as low perceived social support (LPSS) as a modifier of these associations.

METHODS

Multinomial logistic regression models were used to examine the associations of DSI and single sensory impairment (hearing [pure-tone average > 25 dB] and vision [impaired visual acuity and/or contrast sensitivity]) with long-term depressive symptom (≥8 on the 10-item Center for Epidemiologic Studies-Depression Scale) and anxiety symptom (present on the Hopkins Symptom Checklist) latent classes from group-based trajectory models (rare/never; mild/moderate increasing; chronically high) among 2102 Health, Aging and Body Composition Study participants (mean age:74.0 ± 2.8 years; 51.9 % female) over 10 years. Models were adjusted by demographic characteristics and cardiovascular risk factors, and LPSS. An additional model evaluated the two-way interaction between DSI and LPSS.

RESULTS

DSI was associated with increased risk of being chronically depressed (Risk Ratio, RR = 1.99, 95 % Confidence Interval, CI: 1.25, 3.17), not mild/moderate increasingly depressed (RR = 1.25, 95 % CI: 0.91, 1.71). DSI had increased risk of being mild/moderate increasingly anxious (RR = 1.60, 95 % CI: 1.16, 2.19) and chronically anxious (RR = 1.86, 95 % CI: 1.05, 3.27) groups, as compared to no impairments. Hearing impairment was associated with being mild/moderate increasingly anxious (RR = 1.34, 95 % CI: 1.01, 1.79). No other associations were found for single sensory impairments. LPSS did not modify associations.

LIMITATIONS

Sensory measures were time-fixed, and LPSS, depression and anxiety measures were self-reported.

CONCLUSIONS

Future research is warranted to determine if DSI therapies may lessen long-term chronically high depressive and anxiety symptoms.

Self-Reported Sensory Decline in Older Adults Is Longitudinally Associated With Both Modality-General and Modality-Specific Factors

Background and Objectives

Self-reported sensory data provide important insight into an individual's perception of sensory ability. It remains unclear what factors predict longitudinal change in self-reported sensory ability across multiple modalities during healthy aging. This study examined these associations in a cohort of older adults for vision, hearing, taste, and smell.

Research Design and Methods

Data on self-report sensory ability were drawn from 5,065 participants of The Irish Longitudinal Study on Ageing (mean age at baseline = 61.6, SD = 9.5, range 32-93 years; 59% female; resident in the Republic of Ireland) across 6 waves of data collection (2009-2021). Covariates included demographics, lifestyle factors, and measures of sensory, physical, mental, and cognitive health. Independent discrete survival analyses were performed for each sensory modality.

Results

A transition to self-reported fair/poor hearing was most prevalent (21% of the sample), followed by fair/poor vision (19%), smell (11%), and taste (6%). Participants who self-reported fair/poor function in one sensory modality were likely to report fair/poor ability in another sensory modality, although not for all pairings. Only self-rated fair/poor health was associated with increased odds of self-reported fair/poor ability across all sensory modalities. Age was associated with increased odds of self-reported fair/poor hearing, smell, and taste, as was current smoker status (vision, smell, and taste). Several other sensory (e.g., eye disease, hearing aid use) and nonsensory covariates (e.g., education, depression) were associated with the odds of self-reported fair/poor ability in one or two sensory modalities only.

Discussion and Implications

Over time, older adults perceive associations in fair/poor ability for multiple sensory modalities, albeit somewhat inconsistently. Both modality-general and modality-specific factors are associated with a transition from normal to fair/poor sensory ability. These results suggest the need for more routine testing of multiple senses with increasing age.

The impact of COVID-19 on the everyday life of blind and sighted individuals

The COVID-19 pandemic caused unexpected and unavoidable changes in daily life worldwide. Governments and communities found ways to mitigate the impact of these changes, but many solutions were inaccessible to people with visual impairments. This work aimed to investigate how blind individuals subjectively experienced the restrictions and isolation caused by the COVID-19 pandemic. To this end, a group of twenty-seven blind and seventeen sighted people took part in a survey addressing how COVID-19 impacted life practically and psychologically, how it affected their daily habits, and how it changed their experiences of themselves and others. Results demonstrated that both sighted and blind individuals had a hard time adapting to the new situation. However, while sighted people struggled more with personal and social aspects, the frustration of the blind population derived mostly from more practical and logistical issues. Likely as consequences, results showed that blind people engaged more in their inner life and experienced fear and anger as main emotions. This study suggests that changes in life associated with COVID-19 have been subjectively experienced differently based on the presence or not of blindness, and that tailored future interventions should be considered to take care of the different needs of blind individuals.

Association of Visual Health With Depressive Symptoms and Brain Imaging Phenotypes Among Middle-Aged and Older Adults

IMPORTANCE

Vision loss and depression are common conditions with major health implications. However, mechanisms of the association of visual health (across the full acuity spectrum) with depression remain unclear.

OBJECTIVE

To characterize the association between visual health and depression and investigate the association between depression and brain microstructure and macrostructure in subgroups divided by visual acuity.

DESIGN, SETTING, AND PARTICIPANTS

In the UK Biobank Study cohort, 114 583 volunteers were included at baseline from March to June 2006 to July 2010. Habitual distance visual acuity was examined using the logarithm of the minimum angle of resolution (LogMAR) characters. Depression was identified based on Patient Health Questionnaire (PHQ) or through an interview-based psychiatric diagnosis. Subgroup participants completed multimodal magnetic resonance imaging (MRI) of the brain and PHQ evaluation during the imaging visit after 2014. Data were analyzed from May 5 to August 9, 2022.

MAIN OUTCOMES AND MEASURES

Depression, depressive symptoms, and imaging-derived phenotypes from T1-weighted and diffusion MRI.

RESULTS

Of the 114 583 participants from the UK Biobank Study, 62 401 (54.5%) were women, and the mean (SD) age was 56.8 (8.1) years (range, 39-72 years). A 1-line worse visual acuity (0.1 LogMAR increase) was associated with 5% higher odds of depression (odds ratio, 1.05 [95% CI, 1.04-1.07]) after adjustment for age, sex, race and ethnicity, Townsend index, educational qualifications, smoking, alcohol consumption, obesity, physical activity, history of hypertension, diabetes, hyperlipidemia, and family history of depression. Of the 7844 participants eligible for MRI analysis, there were linear associations between PHQ score and the left volume of gray matter in supracalcarine cortex (coefficient, 7.61 [95% CI, 3.90-11.31]) and mean isotropic volume fraction (ISOVF) in the right fornix (cres) and/or stria terminalis (coefficient, 0.003 [95% CI, 0.001-0.004]) after correction for multiple comparison. In addition, their association could be moderated by visual acuity, whereby increased PHQ score was associated with higher ISOVF levels only among those with poorer visual acuity (P = .02 for interaction).

CONCLUSIONS AND RELEVANCE

This study suggests an association between visual health and depression and that the diffusion characteristic of ISOVF in the fornix (cres) and/or stria terminalis is associated with depressive symptoms in participants with poorer visual acuity.

The Longitudinal Association of Late-Life Visual and Hearing Difficulty and Cognitive Function: The Role of Social Isolation

OBJECTIVES

Sensory impairments are prevalent among older adults and have been associated with cognitive challenges in later life, yet mechanisms are less well understood. We examined the mediating role of social isolation in the longitudinal relationship between self-reported sensory difficulty and impaired cognitive functioning among older adults.

METHODS

Data were taken from the NHATS Study, an annual survey of Medicare beneficiaries' age ≥ 65. Participants (N = 6,338) provided data at Rounds 5, 6, and 7 (2015, 2016, 2017). Structural equation models were estimated to test longitudinal direct and indirect associations.

RESULTS

All sensory difficulties were negatively associated with all cognitive functioning measures cross-sectionally through social isolation. Longitudinally, vision difficulty and dual sensory difficulty were indirectly associated with cognitive functioning across time. Hearing difficulty had no longitudinal indirect associations with cognitive functioning through social isolation.

DISCUSSION

Social isolation is an important pathway through which late-life vision difficulty is associated with decreased cognitive function.

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 between dual sensory impairment and risk of mortality: a cohort study from the UK Biobank

BACKGROUND

Dual sensory impairment is affecting over 10% of older adults worldwide. However, the long-term effect of dual sensory impairment (DSI) on the risk of mortality remains controversial. We aim to investigate the impact of single or/and dual sensory impairment on the risk of mortality in a large population-based sample of the adult in the UK with 14-years of follow-up.

METHODS

This population-based prospective cohort study included participants aged 40 and over with complete records of visual and hearing functions from the UK Biobank study. Measurements of visual and hearing functions were performed at baseline examinations between 2006 and 2010, and data on mortality was obtained by 2021. Dual sensory impairment was defined as concurrent visual and hearing impairments. Cox proportional hazards regression models were employed to evaluate the impact of sensory impairment (dual sensory impairment, single visual or hearing impairment) on the hazard of mortality.

RESULTS

Of the 113,563 participants included in this study, the mean age (standard deviation) was 56.8 (8.09) years, and 61,849 (54.5%) were female. At baseline measurements, there were 733 (0.65%) participants with dual sensory impairment, 2,973 (2.62%) participants with single visual impairment, and 13,560 (11.94%) with single hearing impairment. After a follow-up period of 14 years (mean duration of 11 years), 5,992 (5.28%) participants died from all causes. Compared with no sensory impairment, dual sensory impairment was significantly associated with an estimated 44% higher hazard of mortality (hazard ratio: 1.44 [95% confidence interval, 1.11-1.88], p = 0.007) after multiple adjustments.

CONCLUSIONS

Individuals with dual sensory impairment were found to have an independently 44% higher hazard of mortality than those with neither sensory impairment. Timely intervention of sensory impairment and early prevention of its underlying causes should help to reduce the associated risk of mortality.

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.

Cognitive impairment in the population-based ural very old study

Background

Despite its marked importance in public health, the prevalence of cognitive impairment (CI) and its associated factors have only rarely been examined in old populations in general or in Russia at all.

Objective

To assess CI prevalence and its determinants in a very elderly population in Russia.

Materials and methods

The population-based Ural Very Old Study, conducted in rural and urban region in Bashkortostan/Russia, included 1,526 (81.1%) out of 1,882 eligible individuals aged 85+ years. A series of medical examinations including the Mini-Mental State Examination (MMSE) for the assessment of CI was performed.

Results

Mini-Mental State Examination data were available for 1,442 (94.5%) individuals (mean age: 88.3 ± 2.9 years; range: 85–103 years). The median MMSE score was 24 (interquartile range: 19, 27). Prevalence of any CI (MMSE score < 24 points) was 701/1,442 [48.6%; 95% confidence interval (CI): 46.0, 51.2]. Prevalence of mild, moderate and severe CI (MMSE score 19–23 points, 10–18 points, and ≤9 points, respectively) was 357/1,442 (24.8%; 95% CI: 22.5, 27.0), 246/1,442 (17.1%; 95% CI: 15.1, 19.0), and 98/1,442 (6.8%; 95% CI: 5.5, 8.1), resp. A lower MMSE score correlated (regression coefficient r²: 0.31) with older age (beta: −0.13; P < 0.001), rural region of habitation (beta: 0.15; P < 0.001), lower level of education (beta: 0.19; P < 0.001), higher depression score (beta: −0.33; P < 0.001) (or alternatively, higher prevalence of hearing loss (beta: −0.10; P = 0.001), worse visual acuity (beta: −0.10; P = 0.001), and lower physical activity (beta: 0.06; P = 0.04).

Conclusion

In this elderly study population from rural and urban Russia, prevalence of any, mild, moderate and severe CI was 48.6, 24.8, 17.1, and 6.8%, resp. Besides medical and lifestyle factors, vision and hearing impairment were major factors associated with CI.

Associations of self-reported vision impairment with depression symptoms among middle-aged and older Chinese

BACKGROUND

Vision impairment (VI) and depression are highly prevalent among adults. However, few nationally representative studies from China on the self-reported VI and its association with depression symptoms.

AIMS

This study re-estimated the relationship between self-reported VI and depression symptoms.

METHODS

In this analysis, 62,525 respondents from the China Health and Retirement Longitudinal Study 2011-2018 were included. Based on self-reports, respondents with VI were allocated to distance VI (DVI), near VI (NVI), both distance and near VI (DNVI), or a blindness group. Multivariable pooled logistic regression models were used to evaluate the groups' odds ratios (ORs) for depression symptoms and self-reported VI.

RESULTS

Overall, 35.9% of the respondents were self-reported VI. DVI (OR: 1.51, 95% confidence interval [95% CI]: 1.28-1.79) and DNVI (OR: 1.51, 95% CI: 1.21-1.88) showed the highest ORs for depression symptoms, followed by NVI (OR: 1.31, 95% CI: 1.11-1.54). Depression symptoms were associated with a significantly increased risk of DVI (OR: 1.49, 95% CI: 1.26-1.76), DNVI (OR: 1.49, 95% CI: 1.20-1.86), and NVI (OR: 1.29, 95% CI: 1.10-1.52), respectively. However, these associations between self-reported blindness and depression symptoms were not significant. All models provided similar results by excluding respondents aged 45-59 years.

CONCLUSION

Self-reported DVI, NVI, and DNVI are associated with depression symptoms. A strong reverse association was found between depression and self-reported DVI, NVI, and DNVI, but not for blindness. Our findings emphasize the urgent need for depression screening for self-reported VI among Chinese adults.

Associations of walking impairment with visual impairment, depression, and cognitive function in U.S. older adults: NHANES 2013-2014

BACKGROUND

Walking impairment, a common health problem among older adults, has been linked to poor vision and mental health. This study aimed to investigate the associations of walking impairment with visual impairment, depression, and cognitive function in older adults.

METHODS

A total of 1,489 adults aged 60 years and older who had participated in the National Health and Examination Survey (NHANES) 2013-2014 in the United States were included. Multivariate logistic regression models were used to examine the associations of walking impairment with visual impairment, depression, and four subdomains of cognitive function. Sample weights were used to ensure the generalizability of the results.

RESULTS

Among all the participants (median age = 68 years; 53.7% women), 17.5% reported walking impairment. Walking impairment was significantly associated with visual impairment (adjusted odds ratio [aOR] = 2.76; 95% CI: 1.47-5.20) and depression (aOR = 4.66; 95% CI: 3.11-6.99). Walking impairment was only associated with the Digit Symbol Substitution (DSST) subdomain of cognitive function in total participants (aOR = 0.97; 95% CI: 0.95-0.99) and in non-Hispanic white adults (aOR = 0.96; 95% CI: 0.94-0.98). Participants with two or three impairment indicators had a higher OR of walking impairment (aOR = 3.64, 95% CI = 2.46-5.38) than those with 0-1 (reference group) impairment indicator.

CONCLUSIONS

Walking impairment was associated with visual impairment, depression, and cognitive impairment in American older adults and also positively associated with the number of impairment indicators. The association between walking impairment and cognitive impairment varied according to race. Evaluations of vision, cognition, and depression should be conducted among older adults with walking impairment, and the needs of older adults should be provided in the evaluations alongside information on the biological aspects of their particular race.

Concurrent vision and hearing impairment associated with cognitive dysfunction in a population aged 85+ years: the Ural Very Old Study

OBJECTIVE

To assess the prevalence of vision impairment, hearing impairment and dual sensory impairment (DSI) as combination of vision and hearing impairment, in association with cognitive dysfunction in a population aged 85+ years.

METHODS

The cross-sectional population-based Ural Very Old Study, conducted in rural and urban Bashkortostan, Russia, between 2017 and 2020, included a detailed ocular and systemic examination with assessment of moderate to severe vision impairment (MSVI)/blindness (best-corrected visual acuity <6/18), moderate to severe hearing loss (MSHL) and cognitive function.

SETTING

A rural and urban area in Bashkortostan, Russia.

PARTICIPANTS

Out of 1882 eligible individuals aged 85+ years, 1526 (81.1%) individuals participated.

PRIMARY AND SECONDARY OUTCOME MEASURES

Prevalence of vision, hearing and DSI and cognitive dysfunction.

RESULTS

The study included 731 (47.9%) individuals (mean age 88.1±2.7 years; median 87 years, range 85-98 years) with measurements of MSVI/blindness, MSHL and cognitive function. The prevalence of MSVI/blindness, MSHL, DSI and dementia were 51.8% (95% CI 48.2% to 55.5%), 33.1% (95% CI 29.7% to 36.5%), 20.5% (95% CI 17.8% to 23.5%) and 48.2% (95% CI 44.5% to 51.8%), respectively. Lower cognitive function score was associated with lower visual acuity (p<0.001) and higher hearing loss score (p=0.03), after adjusting for older age (p=0.001), rural region of habitation (p=0.003), lower educational level (p<0.001) and higher depression score (p<0.001). Higher dementia prevalence was associated with higher MSHL prevalence (OR 2.18 95% CI 1.59 to 2.98; p<0.001), higher MSVI/blindness prevalence (OR 2.09, 95% CI 1.55 to 2.81; p<0.001) and higher DSI prevalence (OR 2.80, 95% CI 1.92 to 4.07; p<0.001).

CONCLUSIONS

In this very old, multiethnic population from Russia, DSI (prevalence 20.5%), as compared with hearing impairment (OR 2.18) and vision impairment alone (OR 2.09), had a stronger association (OR 2.80) with dementia. The findings show the importance of hearing and vision impairment, in particular their combined occurrence, for dementia prevalence in an old population.
