  • 简介:沙眼是由沙眼衣原体感染所致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 2020)列为其防盲工作主要目标之一。世界卫生组织制定了辨认和命名沙眼简化分级系统及以社区干预为基础防治沙眼SAFE策略,此后10余年各国对此策略进行了不断推广、执行,目前世界上沙眼流行趋势较之此前有了一定变化,我国也启动了“计划2016年前在中国根治致盲性沙眼”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。
