慢性闭角型青光眼是中国蒙古族人群中最常见的青光眼。Tt是眼前段的解剖学疾病，其特征在于由于虹膜与小梁网贴壁而导致部分滤过角永久性闭合。两种途径导致这种情况：复发性瞳孔阻滞和“蠕动”房角关闭。东亚或东南亚种族背景是慢性闭角型青光眼发生的重要危险因素。其他人口统计学风险因素包括老龄化、女性和家庭倾向。慢性闭角型青光眼患者与正常人相比，眼前节解剖关系不同。存在风险的眼睛往往是远视眼，具有浅前房、相对靠前的透镜和短眼轴长度。睫状体解剖和睫状突在这种情况下的发病机制中的作用需要进一步研究。(C)1998 Elsevier Science Ltd.保留所有权利。
Chronic angle-closure glaucoma is the commonest form of glaucoma in Sino-Mongaloid populations. Tt is an anatomical disorder of the anterior segment of the eye characterised by permanent closure of part of the filtration angle as a result of iris apposition to the trabecular meshwork. Two pathways lead to this condition: recurrent pupillary block and "creeping" angle closure. East or Southeast Asian ethnic background is an important risk factor for the development of chronic angle-closure glaucoma. Other demographical risk factors include ageing, female gender and a familial tendency. Eyes with chronic angle-closure glaucoma have different anterior segment anatomical relationships when compared io normals. Those eyes ai risk tend to be hypermetropic with a shallow anterior chamber, a relatively anteriorly positioned lens and a short axial length. The role of the ciliary body anatomy and ciliary processes in the pathogenesis of this condition requires further investigation. (C) 1998 Elsevier Science Ltd. AII rights reserved.
