Abstract
- Bilateral visual impairment includes participants with visual impairment in one eye and visual impairment/blindness in the other eye. e Presence of any existing cataract or any history of cataract surgery in either eye (Modified Wisconsin Cataract Grading System). f Among diabetic individuals. g VTDR, vision-threatening diabetic retinopathy. Bilateral visual impairment includes participants with visual impairment in one eye and visual impairment/blindness in the other eye. d Based on the WHO definition, visual impairment was defined as VA<20/60 to 20/400. The overall age-adjusted BCVA prevalence of bilateral blindness (VA< 20/200, based on the better-seeing eye) and VI (VA< 20/40 to 20/200, based on the better-seeing eye) was 0.3% [95% confidence interval (CI) 0.2-0.4] and 4.2% (95% CI 3.8- 4.5), respectively. Globally, blindness and visual impairment (VI) are estimated to affect 36 million and 400 million people, respectively. [Extracted from the article]
