title: [Survey and treatment of the blind in Xinhui, Guangdong, China].
abstract: Co-operating with Helen Keller International (HKI) in 1987 and 1988, Zhongshan Ophthalmic Center made a large scale prevalent survey of the blind in Xinhui, Guangdong, China. Three screening methods were used in the project. The first was a house-to-house visit by ophthalmologists. The second was performed initially by trained country health workers and then checked by ophthalmologists. In the third one, the blind people were asked to come together to be examined by ophthalmologists. The second method was found to be the most effective. The survey revealed that the prevalent rate of blindness was 0.24% in the county. Of all the blind, 89% were over 50 years old, 73% were females. Cataract accounted for 47% of the blindness. Thirty percent of the blind from cataract received surgical treatment. The postoperative re-examination half a year later showed that the corrected visual acuity in 86% of the patients was more than 0.05.
