Patterns and risk factor profiles of visual loss in a multi-ethnic Asian population: The Singapore Epidemiology of Eye Diseases Study
American Journal of Ophthalmology May 21, 2019
Wong TY, et al. - Researchers examined 10,020 participants (a multi-ethnic Asian cohort of Malays, Indians and Chinese) from the Singapore Epidemiology of Eye Diseases (SEED) Study for the pattern and risk factor traits associated with visual loss (defined as either visual impairment[VI] or blindness). Compared to Indians (3.6%; 18.0%) and Chinese, Malays exhibited higher age-standardised prevalence of best-corrected and presenting VI. Across the three ethnic groups, cataract was the main cause for presenting and best-corrected blindness; the top causes for best-corrected VI consistently included cataract and diabetic retinopathy. Risk of best-corrected visual loss was higher in independent correlation to older age, female gender, lower socioeconomic status, diabetes, systemic comorbidities and cognitive impairment. Compared to younger, non-diabetic individuals, individuals aged≥60 years with diabetes were 12.7 times more likely to have best-corrected visual loss. Best-corrected visual loss is related to lower income and education among 58.1% and 23.2% in this population, respectively.
