简介：青光眼是全球第二大致盲眼病,是不可逆性盲最主要原因,而原发性闭角型青光眼（primaryangleclosure[1]glaucoma,PACG）是我国最主要的青光眼类型。原发性闭角型青光眼（PACG）的发病机制复杂。PACG发病的主要危险因素是晶状体位置偏前、前房变浅而导致的瞳孔阻滞。此外,周边虹膜肥厚以及睫状体位置前移也是PACG发病的常见危险因素。

简介：糖尿病视网膜病变(diabeticretinopathy,DR),作为可导致糖尿病(diabetesmellitus,DM)患者出现严重视力下降的病因之一,其发病人数也随糖尿病患者的人数逐渐增加而逐年递增,因其致盲率高,已成为我国巨大的社会负担和压力。罹患糖尿病多年的患者很多对自己的视网膜发生病变没有察觉,因此病情一旦发现往往已严重影响患者视力.

简介：对于原发性开角型青光眼（POAG），治疗的基本原则是通过药物、手术或激光等方式降低眼压，但是患者的日常生活习惯对治疗后眼压的控制、病情的缓解有着不可忽视的影响。日常生活中影响眼压和POAG病情发展的相关因素主要有饮酒、吸烟、运动、肥胖和饮用咖啡、茶等。本文主要就流行病学调查方面研究结果，进行了分析总结，提出在日常生活方面的注意事项，给眼科医生提供相关信息，给患者提供生活指导。
