摘要
目的 调查广东省斗门县５０ 岁以上农民视力状况及致盲原因。方法 对广东省斗门县５０ 岁以上农民进行视力抽样调查。在９５％ 的可信限、０３６％ 允许误差、１２５ 抽样作用系数及８５ ％ 应答率的条件下，采用整群随机抽样。视力检查采用糖尿病视网膜早期治疗研究视力表测定日常生活视力，由眼科医生做外眼、前房、晶体、眼底、眼压等检查， 对所有视力＜ ０３ 的患眼进行主要致病原因的诊断。由两个组经预试验检测一致性满意后，执行现场工作。结果 在３６ 个抽样单位内检查５ ３４２ 例，受检率９２７６ ％ ，盲患病率为２６７ ％ ，低视力率为１９９１ ％ ，５０ 岁年龄组盲患病率为０６３ ％ ，而７０ 岁以上年龄组盲患病率为５７２％ 。无文化者盲为５ 年文化程度盲的４５ 倍。而男、女间盲患病率的差异无显著性。致盲原因依次为白内障（４４９０％ ） 、角膜混浊（１６３６ ％ ） 、眼球萎缩或无眼球（１０７６ ％ ） 、屈光不正（７０８ ％ ） 及青光眼（５８８ ％ ） 。结论 农村５０ 岁以上农民盲患病率和低视力率分别为２６７ ％ 和１９９１ ％ 。首位致盲原因为白内障。
Objective To investigate the vision distribution and the leading cause of blindness in farmer aged ≥50 years in Doumen county Methods Cluster sampling size was estimated within an error bound of 0 35% with 95% confidence limit, 1 25 design effect and 85% response rate Presenting visual acuity was measured by ETDRS (early treatment diabetic retinopathy study) tumbling chart Eye examinations of external eye, anterior chamber, lens, fundus and intraocular pressure were carried out by ophthalmologists A diagnosis of the principal cause for all the eyes with presenting visual acuity less than 0 3 was made as well The field survey was conducted by two teams after pilot agreement testing Result 5 342 individuals were examined in 36 sampling units The prevalence of blindness was five fold in the group aged ≥70 years than in the group 50～59 years The rate of blindness in the group with less education was higher than the group with 5 years schooling The leading causes of blindness were cataract (44 90%), cornea opacity (16 36%), globe disorders (10 76%), refractive error (7 08%) and glaucoma (5 88%) Conclusions The prevalence of blindness and low vision was 2 67% and 19 91%, respectively in farmers aged ≥50 years The leading cause of blindness was cataract
