New study tests best methods to prevent blindness in rural areas
NCT ID NCT03278587
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested four different approaches to find and treat eye diseases like cataracts, glaucoma, and diabetic retinopathy in communities in Nepal. Over 87,000 people aged 50 and older took part. The goal was to see which method—comprehensive screening, cataract camps, community health workers, or no program—works best to reduce vision loss and is most cost-effective.
