Association of Ophthalmologic Disorders and Depression in the Elderly: A Review of the Literature

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.

Geographic variation in cumulative incidence of private cataract surgery in Australia and its influencing factors: Findings from the 45 and Up Study

PURPOSE

To investigate the geographic variation in the cumulative incidence of private cataract surgery (PCS) and its association with remoteness, socioeconomic, and private health insurance coverage indexes in a large Australian population.

METHODS

A prospective population-based study of 266,896 Australian adults living in New South Wales (NSW) aged 45 years older and over were enrolled in the 45 and Up Study. PCS was identified using Medicare claims data. Participants were assigned to a Statistical Area Level 3 (SA3) based on residential postcode in NSW. Cumulative incidence of PCS (number of surgery per 100,000 population from 2006 to 2016) among 89 SA3s was calculated and standardized to the baseline population. Remoteness and socioeconomic deprivation was derived from Australian Bureau of Statistics (ABS). Private health insurance coverage rates were obtained from the baseline interview.

RESULTS

A total of 257,237 participants with complete data were included in the current analysis. During the study period, a total of 67,707 cataract surgeries were performed among 39,744 participants. Cumulative incidence of PCS varied from 14,897 to 37,314 per 100,000 across 89 SA3s. Multivariable adjusted regression models showed that remoteness index and private health insurance coverage rates were independently associated with cumulative incidence of PCS (all P < 0.05), while no significant association between socioeconomic deprivation and cumulative incidence of PCS was observed. Collectively, these three variables explained 52.7% of the geographic variability.

CONCLUSIONS

The geographical variation in the cumulative incidence of PCS calls for interventions targeted at individuals living in remote areas to reduce the burden of cataract-related vision impairment.

Gender Differences in the Association between Physical Inactivity and Mental-Health Conditions in People with Vision or Hearing Impairment

This study aimed to examine associations between physical inactivity and mental health in Spanish adults with vision or hearing difficulties and explored differences between men and women. Data from the Spanish National Health Survey in 2017 were analyzed (n = 23,089 adults, 15−103 years, mean age 53.4 ± 18.9 years, 45.9% men). Physical inactivity (exposure) was evaluated with the International Physical Activity Questionnaire Short Form. Participants self-reported whether they had previously suffered from depression, chronic anxiety and other mental-health complications (outcomes). Associations between physical inactivity and mental-health complications were assessed with multivariable logistic regression in people with difficulty seeing and hearing, after grouping by gender and adjusting for age, body-mass index, education level, living as a couple, smoking and alcohol consumption. The overall multivariable logistic-regression analyses showed that women with vision impairment showed significant associations between physical inactivity and depression (OR 1.403, 95% CI 1.015−1.940) and other mental-health complications (OR 2.959, 95% CI 1.434−6.104). In the overall analyses, there were no significant associations in men and in people with hearing impairment. The age-stratified analyses showed that inactive people with visual impairment who were <65 years old had a higher risk of mental-health conditions. In conclusion, physical activity has been shown to be important in the prevention of mental-health complications. Healthcare practitioners and policy makers should look at appropriate strategies to increase levels of physical activity in people with vision loss, especially in women and in those <65 years old.

Gender Differences in the Association Between Cataract and Mental Health in Adults With Diabetes: A Cross-Sectional Analysis From the Spanish National Health Survey 2017

Objective: This study aimed to explore gender differences in the associations between cataracts and self-reported depression and chronic anxiety in Spanish adults with diabetes.

Methods: Cross-sectional data from the Spanish Health Survey 2017 were analyzed. Inclusion criterion was a positive response to the question “Have you ever been diagnosed with diabetes?” Diabetes, cataracts, depression and chronic anxiety were based on self-reported lifetime diagnosis. Multivariable logistic regression was conducted to assess the association between cataracts and depression or anxiety among respondents with diabetes, stratifying by gender.

Results: Out of a total 23,089 respondents, 2,266 people self-reported suffering from diabetes (50.2% women; average age 69.7 ± 12.7 years; age range 15-98 years). In people with diabetes, the presence of cataracts was associated with significantly higher odds for depression (OR = 1.655; 95% CI = 1.295-2.115). Gender-stratified analyses showed that only women with cataracts were significantly associated with higher odds for depression (OR = 1.762; 95% CI = 1.307-2.374) and chronic anxiety (OR = 1.519; 95% CI = 1.067-2.163).

Conclusion: Cataracts are a significant risk factor for depression and chronic anxiety in Spanish women with diabetes, but not in men. Women with both diabetes and cataracts require assessment for depression and chronic anxiety, and possibly earlier interventions in order to reduce the potential risk of further mental health complications.

Visual, hearing, and dual sensory impairment are associated with higher depression and anxiety in women

OBJECTIVE

We investigated cross-sectional gender-specific associations with vision, hearing, and both (dual) impairment with depression and chronic anxiety using a large representative sample of Spanish adults.

METHODS

The present study utilized data from the Spanish National Health Survey 2017. A total of 23,089 adults (15-103 years, 45.9% men) participated in this survey. Participants self-reported whether they had suffered depression and/or anxiety, and also whether they experience vision, hearing and both vision/hearing (dual) impairment. Multivariable logistic regression analyses were conducted to assess the associations between the three types of sensory impairment and anxiety or depression, in men and women.

RESULTS

Across the whole sample (n = 23,089) the prevalence of depression and anxiety was between 2.00 and 2.56 times higher in women compared to men. Dual sensory impairment (hearing and vision) was associated with higher levels of depression (odds ratio [OR] = 2.980, 95% confidence interval [CI]: 2.170-4.091) and anxiety (OR = 2.636, 95% CI: 1.902-3.653) compared to single sensory impairment. Stratified associations by gender showed higher odd ratios for women with dual sensory loss (3.488 for depression and 3.478 for anxiety) compared to men (2.773 for depression and 1.803 for anxiety).

CONCLUSIONS

Dual sensory impairment (hearing and seeing) is are associated with increased depression and anxiety. Women with dual sensory impairment showed stronger associations compared to men among adults in Spain. Interventions are needed to address vision and/or hearing impairment in order to reduce anxiety and depression especially in women.

Association of vision problems with psychosocial factors among middle-aged and older individuals: findings from a nationally representative study

Objectives: Little is known about the specific association of vision loss and psychosocial outcome measures in contrast to other health limitations. The aim of this study was to identify whether vision problems are associated with psychosocial outcomes among middle-aged and older adults and to compare it with the association between other chronic health conditions and psychosocial factors.Method: Cross-sectional data came from wave 5 (2014) of the German Ageing Survey which is a representative sample of non-institutionalized individuals ≥ 40 years in Germany. Psychosocial outcomes (life satisfaction, positive affect, negative affect, depressive symptoms, optimism, general self-esteem, and social isolation) were assessed using well-established and widely used scales. Self-rated trouble reading the newspaper due to vision problems and self-rated difficulties recognizing known people on the street due to vision problems were used as independent variables of interest.Results: Regressions showed that both 'vision problems: reading the newspaper' and 'vision problems: difficulties recognizing people' are consistently associated with worse psychosocial outcomes (decreased life satisfaction, decreased positive affect, increased negative affect, increased depressive symptoms, decreased optimism, decreased self-esteem and increased social isolation). In contrast, none of the physical illnesses was consistently associated with all psychosocial outcome measures.Conclusion: Adjusting for various potential confounders and in contrast to various chronic diseases, our findings emphasize an association between vision problems and worse psychosocial outcomes in middle-aged and older adults. Future longitudinal studies are needed to validate our findings.

Depression in glaucoma patients: A review of the literature

Purpose: The purpose of this review was to evaluate the association between glaucoma and depression and to identify possible risk factors for depressive symptoms in glaucoma patients.Methods: A total of 587 abstracts were screened and 32 studies were deemed eligible for inclusion in this review.Results: An association of glaucoma and depression was found, while advanced disease stage, older age, female sex and faster visual loss progression were recognized as potential risk factors for depression in patients with glaucoma.Conclusions: Our findings may have important clinical significance, such as alerting ophthalmologists to implement a multidisciplinary approach in patients with glaucoma. Further research is needed to examine this association in different types of glaucoma and try to investigate the underlying pathophysiological mechanisms to establish a causal inference between glaucoma and depression.

Combined Vision and Hearing Difficulties Results in Higher Levels of Depression and Chronic Anxiety: Data From a Large Sample of Spanish Adults

OBJECTIVE

Individually, vision and hearing impairments have been linked to higher levels of anxiety and depression. We investigated the effect of dual sensory impairment (difficulty seeing and hearing) in a large representative sample of Spanish adults.

METHODS

Data from a total of 23,089 adults (age range: 15-103 years, 45.9% men) from the Spanish National Health Survey 2017 were analyzed. Self-reported difficulty of seeing and hearing (exposures), and depression and chronic anxiety (outcomes) were analyzed. Multivariable logistic regression was assessed for difficulty with vision alone, hearing alone and with difficulty with both, adjusting for gender, age, marital status, living as a couple, education, smoking, alcohol consumption, BMI, physical activity, use of glasses/contact lenses, and hearing aid.

RESULTS

Visual difficulty, hearing difficulty, and dual difficulties were all associated with significantly higher odds for depression (ORs 2.367, 2.098, and 3.852, respectively) and for chronic anxiety (ORs 1.983, 1.942, and 3.385, respectively). Dual sensory difficulty was associated with higher odds ratios for depression and anxiety when compared to either impairment alone.

CONCLUSION

Dual sensory difficulty is associated with significantly higher odds of anxiety and depression when compared to either vision or hearing difficulty alone. Appropriate interventions are needed to address any reversible causes of vision and hearing as well as anxiety and depression in people in these specific groups.

Mastery and self-esteem mediate the association between visual acuity and mental health: a population-based longitudinal cohort study

BACKGROUND

With deteriorating eyesight, people often become dependent on others for many aspects of their daily lives. As a result, they feel less 'in control' and experience lower self-esteem. Lower sense of mastery and self-esteem are known to predict depression, but their roles in people with visual impairment have only marginally been investigated. Therefore, this study aimed to determine the influence of mastery and self-esteem on the relationship between visual acuity and mental health.

METHODS

A longitudinal cohort study was performed using data from the Longitudinal Aging Study Amsterdam (LASA), collected between 2001 and 2012. A community-based population of 2599 older adults were included, who were randomly selected from population registers. Outcomes of interest were the Pearlin Mastery Scale, Rosenberg Self-Esteem Scale, Center for Epidemiologic Studies - Depression scale and the Hospital Anxiety Depression Scale - Anxiety subscale. Linear mixed models were used to establish the association between visual acuity and mental health over time.

RESULTS

Mean age was 72 years, 56% was female and 1.2% qualified as having low vision. Visual impairment was associated with a lower sense of mastery (β = - 0.477, p < 0.001), lower self-esteem (β = - 0.166, p = 0.008) and more depression (β = 0.235, p < 0.001). No significant association between visual acuity and anxiety was found. The relationship between visual acuity and depression was mediated by self-esteem (25%) and sense of mastery (79%).

CONCLUSIONS

Vision loss was associated with depression. This association was mediated by self-esteem and sense of mastery. This provides us with new possibilities to identify, support and treat those at risk for developing depression by aiming to increase their self-esteem and sense of mastery.

LncRNAs in ocular neovascularizations

The prevalence of eye diseases worldwide is dramatically increasing and represents a major concern in underdeveloped and developed regions. Ocular diseases, previously associated with a higher depression risk, also impose a substantial economic burden on affected families, thus early detection and/or accurate treatment in order to avoid and prevent blindness should be emphasized. Ocular neovascularization (NV), the leading cause of blindness in a variety of eye diseases, is a pathologic process characterized by the formation, proliferation and infiltration of anomalous, tiny and leaky fragile blood vessels within the eye. Genetics have been suspected to play an important role in the occurrence of eye diseases, with the detection of a numbers of specific gene mutations. Long non-coding RNA (lncRNAs) are novel class of regulatory molecules previously associated with various biological processes and diseases, however the nature of the relation and pathways by which they might contribute to the development of corneal, choroidal and retinal NV have not yet been completely elucidated. In this review, we focus on the regulation and characteristics of lncRNAs, summarize results from ocular NV-related studies and discuss the implication of lncRNAs in ocular NV development.

Psycho-ophthalmology: Contributions of Health psychology to the assessment and treatment of glaucoma

BACKGROUND

Asymptomatic in its early stages, glaucoma is the second leading cause of blindness worldwide. While psychosocial factors are taken into consideration for a host of diseases such as cancer, heart disease and autoimmune conditions, to date, psychological issues have been ignored in the clinical management of glaucoma.

OBJECTIVE

This work reviews the most relevant contributions from a health psychology perspective for the assessment and treatment of glaucoma, which is emerging in the field of psycho-ophthalmology.

METHOD

To provide scientific evidence regarding contributions of psychology to the comprehension of glaucoma, a bibliographic review of three databases (Psicodoc, PsycInfo and Medline) was conducted, spanning the period between 1940 and 2016.

RESULTS

This review yielded a total of 66 studies published in the period analysed and identified three areas where health psychology has made substantive contributions to glaucoma screening, monitoring and treatment: the emotional impact on patients suffering from glaucoma, the adherence to treatment and the effects of stress on intraocular pressure.

CONCLUSIONS

A health psychology approach for research and therapy of glaucoma must focus on the management of the negative affect associated with the diagnosis, the optimisation of treatment adherence and the stress management of the intraocular pressure measurements.

Novel Insights into the Role of Long Noncoding RNA in Ocular Diseases

Recent advances have suggested that long noncoding RNAs (lncRNAs) are differentially expressed in ocular tissues and play a critical role in the pathogenesis of different types of eye diseases. Here, we summarize the functions and mechanisms of known aberrantly-expressed lncRNAs and present a brief overview of relevant reports about lncRNAs in such ocular diseases as glaucoma, proliferative vitreoretinopathy (PVR), diabeticretinopathy (DR), and ocular tumors. We intend to highlight comprehensive studies that provide detailed data about the mechanisms of lncRNAs, their applications as diagnostic or prognostic biomarkers, and their potential therapeutic targets. Although our understanding of lncRNAs is still in its infancy, these examples may provide helpful insights into the methods by which lncRNAs interfere with ocular diseases.
