Abstract
Approximately 2% of older adults currently live in nursing homes. It is important that the risks for vision loss be characterized to ensure appropriate vision care is provided for nursing home patients. Our objective was to evaluate the association of age-related eye diseases (AREDs) and multimorbidities with vision loss. Cross-sectional study. This is a cross-sectional analysis of comprehensive eye examination records for 7753 residents of 74 North Carolina nursing homes who were ≥65years of age at time of the initial patient visit. Complete data on vision and associated factors were included from the standardized Centers for Medicare and Medicaid Services eye examination. We defined vision impairment and blindness respectively as best-corrected visual acuity between 20/40 and 20/200, and 20/200 or worse. Clinical diagnoses of AREDs were defined by the attending clinician. Data were extracted from electronic health records, and all analyses were conducted in SAS v 9.4. We used descriptive statistics to summarize the resident characteristics and AREDs and logistic regression analysis to examine independent risk factors for vision impairment. A total of 7753 initial eye examination records with complete data were included in the analysis. Overall, 34% of the residents had normal vision, 43% had vision impairment, and 23% were blind. Among participants with various AREDs, the prevalence of vision impaired/blind ranged from 63% to 76%, while blindness ranged from 23% to 53%. We found correction of refractive error alone served to reduce vision impairment or blindness. Comprehensive eye examinations showed vision impairment and blindness affected 66% of nursing home residents, overall. This study substantiates the positive impact of comprehensive eye examinations to promote visual, systemic, and cognitive health and well-being and the need that eye care service be used to inform policy and practice to improve patient functioning and independence.
