摘　　要：原发性闭角型青光眼(PACG)的发病机制包括传统的瞳孔阻滞、非瞳孔阻滞、多种机制共存等类型。实际上,随着年龄增长晶状体阻滞因素在PACG发病中起着十分重要的作用。对PACG抗青光眼术后及晶状体摘除术后眼前段结构变化的研究发现,超声乳化白内障吸出联合人工晶状体植入术可有效地同时解决房角关闭的多个机制。临床医师在选择手术方式时,除考虑患者自身条件外,还应考虑术者对手术的娴熟程度、手术仪器和器械等条件是否适合开展此手术,以使患者得到最佳的眼压控制和良好的视觉质量。As we all know,the traditional pathophysiological mechanisms of primary angle-closure glaucoma（PACG） may include pupillary block,non-pupillary block and combined-mechanisms.At the same time,the role of lens anterior displacement with age in the development of PACG has been recognized in recent years.Studies on the changes of ocular anterior segment structures after lens surgeries have shown that phacoemulsification combined with intraocular lens implantation can solve the possible underlying angle-closure mechanisms at one time.However,we should take more into consideration when we choose this surgical procedure as the first choice for glaucoma patients,including our own skills,the patients＇ condition and the operation equipments,so as to ensure the patients with PACG to receive the best intraocular pressure control and the optimal visual function.
