简介:目的方法结果结论对安徽省两地人群盲和低视力及眼病的流行病学情况进行抽样调查。选择阜阳市颍州区和宣城市绩溪县,采用随机整体抽样方法,对所属居民进行眼部及其他情况的调查。两地的受检人数和受检率分别为3336人(91.40%)和3602人(92.10%),达到抽样调查要求;两地双眼盲、单眼盲、双眼低视力和单眼低视力的患病率分别为1.05%和0.69%、1.71%和1.25%、1.02%和0.97%、0.87%和0.89%;两地盲和低视力的主要原因分别为:白内障、弱视、青光眼和白内障、眼球萎缩/缺如、青光眼;两地主要眼病都为:屈光不正、白内障、翼状胬肉和沙眼;两地的白内障手术率分别为600和278。据不完全资料估计我省盲和低视力的患病率远高于全国平均水平,盲和低视力的高发人群为50岁以上老年人,女性,孤寡,文盲,低收入者,白内障仍是最主要致盲原因,屈光不正/弱视已日益成为影响人民特别是青少年视力的最主要因素,广泛宣传正确用眼方式,推广青少年正确验光配镜方法,提高相关人员验光配镜水平对于有效降低弱视致残率至关重要。
简介:沙眼是由沙眼衣原体感染所致的一种传染性角结膜炎,目前在世界57个国家流行。1998年世界卫生组织(WorldHealthOrganization,WHO)将2020年全球消灭致盲性沙眼(globalalliancetoeliminateblindingtrachomaby2020,GET&nbsp;2020)列为其防盲工作的主要目标之一。世界卫生组织制定了辨认和命名沙眼的简化分级系统及以社区干预为基础的防治沙眼的SAFE策略,此后10余年各国对此策略进行了不断推广、执行,目前世界上沙眼的流行趋势较之此前有了一定的变化,我国也启动了“计划2016年前在中国根治致盲性沙眼”的防盲工作。本文就SAFE策略推广以来沙眼诊断、治疗及流行趋势等方面的进展做一综述。
