Abstract:

PURPOSE: Self-reported visual difficulty is consistently associated with dementia and other neuropsychiatric outcomes, but studies of specific age-related eye diseases have yielded conflicting results. METHODS: We conducted a retrospective cohort study using data from The National Health and Aging Trends Study, an ongoing nationally representative survey of older U.S. adults (? = 10,089). All subjects are screened for self-reported visual difficulty annually. Using linked Medicare claims data, we identified subjects with age-related macular degeneration (AMD), primary open-angle glaucoma (POAG), diabetic retinopathy, and cataract. For each condition, controls with complete Medicare eligibility and at least one eye care encounter were selected. We used semiparametric discrete time proportional hazards models to measure associations with incident dementia, and generalized estimating equations to examine longitudinal associations with depression, anxiety, and hallucinations, adjusting for baseline demographics and time-varying comorbidities. RESULTS: Self-reported visual difficulty was associated with dementia (HR 1.16, 95% CI: 1.00-1.34), depression (OR 1.14, 95% CI: 1.04-1.26), anxiety (OR 1.17, 95% CI: 1.06-1.29), and hallucinations (OR 1.54, 95% CI: 1.29-1.84). Diabetic retinopathy was associated with depression (OR 1.31, 95% CI: 1.05-1.64), and cataracts were associated with a lower risk of depression (OR 0.84, 95% CI: 0.74-0.95) and anxiety (OR 0.86, 95% CI: 0.75-0.99). There were no other associations between age-related eye disease and neuropsychiatric outcomes. CONCLUSION: Self-reported visual difficulty is associated with dementia and other neuropsychiatric outcomes to a greater degree than age-related eye disease. These findings highlight the distinction between self-reported vision and clinically diagnosed eye disease with regard to health outcomes in older adults.
