Objective To measure and evaluate the anterior segment parameters of early primary angle-closure glaucoma patients before and after periphery iridectomy by Pentacam system in order to monitor quantatively the anterior chamber conditions and provide a new way for the screening, study of mechanism and therapy of early primary angleclosure glaucoma patients.

目的通过Pentacam眼前段分析系统在周边虹膜切除术评估的应用，以期为早期原发性闭角型青光眼患者提供一种新的辅助检查方法。

The interventions include laser, surgical and medical therapies. Conclusions Laser peripheral iridoplasty as primary treatment to the acute attack of AACG showed a decrease of intraocular pressure more rapidly than conventional medical treatment. Laser peripheral iridotomy was an efficacious intervention to relieve pupillary block, control IOP, and prevent new attacks. LPI was found to be as effective as surgical peripheral iridectomy in the TOP control of affected or contralateral eyes of AACG.

结论目前已有较为有力证据的治疗方法：急性发作时即刻行激光周边虹膜成形术较传统的药物治疗方案降眼压作用起效快；急性发作缓解后行激光周边虹膜切开术以及对侧眼的预防性LPI，具有解除瞳孔阻滞、控制眼压和预防急性发作再发或新发的效果；LPI和周边虹膜切除手术治疗效果相当。

Results (1)In the group (109 eyes) with preoperative intraocular pressure≤21mmHg,sixty-four eyes were treated with trabeculectomy,and 31 eyes with slerectoiridectomy of which there were 9(14.1%) and 7(20.6%) eyes had undergone PAC respectively.There was no PAC in 11 eyes treated with iridencleisis;(2)In the group(175 eyes)with PIOP from 22 to 35 mmHg,there were 26 eyes(25.2%) and 15 eyes(32.6%) developing PAC of 103 eyes treated with trabeculectomy,and 46 eyes with slerectoiridectomy respectively,of 26 eyes with iridencleisis,there were 5 eyes(19.2%) developing PAC;(3)In the group(106 eyes)with PIOP＞35mmHg,there were 13 eyes(31%) developing PAC of 23 eyes with trabeculectomy,5 eyes(21.7%) developing PAC of 23 eyes with slerectoiridectomy.

We recommend to perform iridotomy during cataract surgery in patients with risk factors to prevent future pupillary block glaucoma.

本症之成因目前仍不確定，我们建议对具有危险因子的病人，在白內障手术时应同时施行手术虹膜切除术，以避免术后瞳孔阻断性青光眼的发生。

METHODS: Fortyeight eyes (39 cases) of primary angleclosure glaucoma underwent combind krypton and Qswitched Nd∶YAG laser peripheral iridotomy.

对我院39例（48眼）原发性闭角型青光眼患者，采用氪离子激光与Q开关Nd∶YAG激光联合应用的方法，行激光周边虹膜切除术。

Methods Separating the posterior synechia with the help of viscoelastics.36 eyes of 32 patients were extract by means of non cuting pupil dilation,excision of the organized membranes of pupilary occlusion and seclusion.

借助粘弹剂分离虹膜后粘连，并采用非切开的瞳孔扩张成型术及膜闭切除术，对32例( 36眼)伴有虹膜后粘连且瞳孔不能放大的葡萄膜炎并发性白内障，行囊外摘出联合人工晶状体植入手术。
