方法：选择于2009-01/2013-05来我院治疗的急性闭角型青光眼患者114例作为本研究的研究对象，年龄36～72岁。将114例患者随机分为观察组和对照组。观察组采取传统巩膜瓣缝合法对本组所有患者巩膜瓣进行缝合； 对照组采取改良巩膜瓣可拆除缝合法对巩膜瓣进行缝合。

结果：术后1d； 2wk； 1，3mo观察组患者术后眼压和对照组相比有差异(P<0.05)； 术后6mo两组眼压无统计学意义； 术后早期浅前房比较观察组与对照组相比差异有统计学意义(P<0.05)，两组患者术后6mo滤过泡形成情况比较无差异(P>0.05)。

结论：改良巩膜瓣可拆除缝合法在急性闭角型青光眼小梁切除术中是安全有效的，较传统方法更能降低早期浅前房的发生率。

METHODS: Totally 114 primary angle-closure glaucoma patients, aged from 36-72 years old, were selected as the objects, and randomly divided into research group and control group. The two groups received different administration methods. Traditional sewing method of sclera flap was used in research group and improved sewing method of sclera flap was used in control group.

RESULTS: There was statistical differences between postoperative intraocular pressure of the patients in the observation group and the control group after 1d; 2wk; 1, 3mo(P<0.05). There was no statistical difference in intraocular pressure between the two groups. There was statistical differences between incidence of shallow anterior chamber of the patients in the observation group and the control group postoperatively early stage(P<0.05). After 6mo, the filtering bleb formation in observation group was no significantly better than control group(P>0.05).

CONCLUSION: It is safe and effective that the improved sewing method of sclera flap for trabeculectomy of acute angle-closure glaucoma, and it is a better method to avoid the occurrence of shallow anterior chamber than the traditional sewing method in the early stage after operation.
