原发性闭角型青光眼流行病学研究进展

青光眼是全球第二大致盲眼病、不可逆性盲最主要的原因。原发性闭角型青光眼(PACG)是亚洲、特别是东亚、中国人中最常见的青光眼类型。随着社会、经济、环境的变化以及诊疗手段的进步,青光眼的流行病学特点不断变化;不同的青光眼诊断标准和分类系统也会导致不同的流行病学调查结果;流行病学的特征又指导着临床干预措施;这一切都密切相关,因此,PACG流行病学状况对青光眼的防治有着重要的意义。本文就国内外PACG流行病学相关研究进展作一综述。

Progress in Prevalence of Primary Angle Closure Glaucoma

Glaucoma has long been recognized as a leading cause of irreversible blindness.According to data on the epidemiology of glaucoma,primary angle closure glaucoma(PACG)is a major form of glaucoma in Asia.This is true especially in populations of East Asian and Chinese descent.The characteristics of glaucomatous epidemiology continued changing with the developments of society,economics and environment.Epidemiologic studies use different diagnostic criteria for the definition of PACG as well as what constitutes an occludable or narrow drainage angle.This will affect estimates of prevalence of the condition in different parts of the world and limit the comparison of published data.Furthermore,the prevalence of glaucoma contributed to clinical interference decisions.All of above are essential to glaucoma and closely related.The recent progress in prevalence of PACG are reviewed as below.
