To evaluate the long-term trend of cataract prevalence and the effect of prevention and treatment blindness in Zhejiang Province.
The data were obtained from handicapped sampling investigation in 1987 and 2006 in Zhejiang Province, and from a database of prevention and treatment blindness of the Zhejiang Province Disabled Persons' Federation.
In 2006, a random sampling investigation were carried out on both eyes blind and the low vision in Zhejiang Province. Sample size were 95,392, the prevalence rate of blindness and low vision were 2.67% per hundred and 5.94% per hundred, respectively. The prevalence rate of cataract was 7.35% per hundred, the female was higher than the male (chi2 = 81.66, P < 0.01). Among the blind, 58.86% was caused by cataract, and the low vision caused by cataract was 63.79%. Comparing with the first disabled person' investigation in 1987, the result showed that the prevalence of blindness had reduces slightly, but no significantly difference (chi2 = 0.384, P = 0.535), and that the prevalence of low vision appeared significantly increase (chi2 = 32.434, P < 0.01). Together with two investigations results indicated that cataract is the first cause for the vision disability.
Cataract is still the first cause for blindness and low vision. Though the effort to prevention and treatment blindness during 20 years obtains some certain results, prevent and treat blindness will still be an arduous work in Zhejiang province, because of accelerated aging population problem, which will induce an increase on number of cataract patient.
评估浙江省白内障患病率的长期趋势以及防盲治盲效果。
数据来源于1987年和2006年浙江省残疾人抽样调查，以及浙江省残疾人联合会防盲治盲数据库。
2006年，对浙江省双眼盲和低视力患者进行随机抽样调查。样本量为95392，盲患病率和低视力患病率分别为0.267%和0.594%。白内障患病率为0.735%，女性高于男性（χ2 = 81.66，P < 0.01）。在盲人中，58.86%由白内障引起，白内障所致低视力占63.79%。与1987年首次残疾人调查相比，结果显示盲患病率略有下降，但差异无统计学意义（χ2 = 0.384，P = 0.535），低视力患病率显著上升（χ2 = 32.434，P < 0.01）。两项调查结果均表明白内障是视力残疾的首要原因。
白内障仍是致盲和低视力的首要原因。尽管20年来防盲治盲工作取得了一定成效，但由于人口老龄化加速导致白内障患者数量增加，浙江省防盲治盲工作仍将艰巨。
