METHODS: Random sampling analysis was performed in 2 569 individuals chosen as the sample aged (greater-than or equal to)50 years in 28 villages of Sanya. Corrected vision, external eye, anterior chamber, lens, vitreous, fundus were examined by ophthalmologists. The prevalence of blindness and low vision was calculated, and the main cause of blindness was analyzed. RESULTS: Totally 2 206 individuals among 2 569 were examined. The response rate was 85.87%, the prevalence of blindness was 1.90% and the prevalence of low vision was 3.85%, resulting chiefly from cataract, glaucoma, keratitis, eyelid disease and pterygium.
