Summary
India
Area of Science:
- Ophthalmology
- Public Health
- Epidemiology
Background:
- Evidence-based planning guides India's blindness control programs.
- A nationwide survey (1999-2001) assessed blindness prevalence and causes.
Purpose of the Study:
- To document the magnitude and causes of blindness in India.
- To evaluate the effectiveness of blindness control efforts.
Main Methods:
- Surveyed individuals aged 50+ in 25 clusters across 15 populous states.
- Recorded presenting and best-corrected vision using logMAR charts.
- Conducted detailed eye examinations.
Main Results:
- 8.5% experienced blindness (presenting vision <6/60 in better eye).
- Cataract caused 62.4% of bilateral blindness (5.3% prevalence).
- Blindness prevalence decreased compared to previous studies, particularly among those 50+.
Conclusions:
- Blindness control programs appear to be slowing the rise in blindness prevalence.
- Achieving "Vision 2020" goals requires political will and prioritized action.
