摘要

目的:探讨应用超声生物显微镜(ultrasound biomicroscopy,UBM)观察瞳孔阻滞型的原发性闭角型青光眼(primary angle-closure glaucoma,PACG)行传统虹膜周边切除术前后前房角的变化。 方法:分析我院自2013年6月至2015年1月收治的确诊PACG(瞳孔阻滞型)26例(37眼),男7例,女19例,年龄42~76岁,其中闭角型青光眼临床前期25眼,前驱期7眼,间歇期5眼,均行虹膜周边切除术。分析术后的治愈率:根据术前、术后应用UBM进行前房测量,对UBM提供的眼前段剖面图进行定性观察和分析,比较术前、术后小梁虹膜夹角、房角开放距离;同时观察虹膜形态的改变。结果:1)本组治愈26例36眼,97.3%(36/37),无效1例1眼,2.7%(1/37);2)治疗前后小梁虹膜夹角、前房角开放距离(AOD500)比较(t=2.155,2.172;P<0.05);3)虹膜周边切除术后虹膜根部组织远离小梁网,房角粘连范围减小。结论:利用UBM观察瞳孔阻滞型闭角型青光眼行虹膜周边切除术前后前房角的变化,可以观察到经手术治疗后,前房角解剖结构的改变,根据小梁虹膜夹角、前房角开放距离、术后虹膜形态改变情况,表明临床上虹膜周边切除术是预防和治疗瞳孔阻滞型闭角型青光眼安全有效的方法。


Angle-closure glaucoma iris week cut the change of anterior chamber angle after ultrasonic biological microscope

Abstract

Objective: To study the application of ultrasonic biological microscope (ultrasound biomicroscopy, UBM) observation of primary angle-closure glaucoma (PACG) surrounding the traditional iris resection before and after the change of anterior chamber angle. Methods: Analysis of our hospital from June 2013 to January 2015 were diagnosed angle-closure glaucoma 26 patients (37 eyes), 7 patients were male, female 19 cases, aged 42~76, the primary closed-angle glaucoma preclinical 23 eyes, 8 eyes prodromal stage, intermittent period 6 eyes, all around the iris resection. Analysis of postoperative cure rate; preoperative and postoperative application of UBM, the measurement of anterior chamber, compare the preoperative postoperative trabecular iris angle, corner open distance; at the same time observe the iris shape change. Results: 1) In 23 cases were cured and 37 eyes of 97.4% (37/38), 1 case ineffective 1 eye, 2.6% (1/38); 2) before and after treatment of trabecular iris angle, the anterior chamber angle open distance 500 (t=2.155, 2.172; P<0.05); 3) after resection of the iris surrounding the iris root tissue away from the trabecular meshwork, adhesion corner radius reduced. Conclusion: ultrasound biomicroscope (UBM) were observed before and after resection of the primary closed-angle glaucoma peripheral iris anterior chamber angle changes, can observe the disease after the situation, determine the trabecular iris angle, anterior chamber angle open distance, postoperative iris change situation, indicates that iris surrounding clinical resection is an effective method for the prevention and treatment of angle-closure glaucoma.
