摘　　要：近年来随着医学技术的发展,激光以其安全、有效、并发症少的优势被广泛应用于青光眼的治疗。临床上针对原发性闭角型青光眼(primary angle-closer glaucoma,PACG)眼压升高的不同机制,应用不同类型的激光技术来治疗。激光周边虹膜切开术(LPI)可以解除瞳孔阻滞因素,开放前房角,增加房水流出;激光周边虹膜成形术(LPIP)可收缩周边虹膜,拉开前房角,解除非瞳孔因素所致房角关闭,使房角增宽;睫状体光凝术(ECP)是在眼内窥镜引导下通过激光破坏睫状体及其血管,减少房水生成,以降低眼压,主要应用于疼痛症状显著的绝对期青光眼。in recent years,with development of medical technology,laser is widely used in treatment of glaucoma because of its advantages of safety,effectiveness and less complications.Clinically,in the light of different mechanisms of intraocular pressure elevation of primary angle closure glaucoma（PACG） patients,different types of laser techniques were applied.Laser peripheral iridotomy（LPI） can relieve pupillary block factor,open anterior chamber angle,increase aqeous humor outflow;and laser peripheral iridoplasty（LPIP） can shrink peripheral iris,open anterior chamber angle,and relieve angle closure caused by non pupillary factors,and widen chamber angle;endoscopic cyclophotocoagulation（ECP） may reduce aqueous humor formation and lower intraocular pressure through laser’s damage to ciliary body and blood vessels guided by ophthalmic endoscope,which is mainly used for glaucoma absolutum with significant pain symptoms.
