方法：将60例68眼本院确诊为原发性急性闭角型青光眼的患者随机分为两组。A组 30例33眼，术中巩膜瓣采用四针缝合法，B组 30例35眼，术中巩膜瓣采用两针缝合法。术后观察眼压、前房深度、滤过泡形态等，随访6mo。

结果：(1)术后第2d两组眼压对比，差异有统计学意义(t=5.8765， P<0.05)； 术后2wk眼压对比，差异无统计学意义(t =1.2347， P>0.05)； 术后1mo眼压对比，差异无统计学意义(t=1.4350， P>0.05)； 术后3mo眼压对比，差异无统计学意义(t=1.3548， P>0.05)； 术后6mo眼压对比，差异无统计学意义(t =1.5753， P>0.05)。(2)术后第2d，A组浅前房发生率为6%，B组为17%，A组浅前房主要以浅Ⅰ度为主，两组对比差异有统计学意义(χ²=6.4513， P<0.05)； 术后第1wk， A 组浅前房发生率为0， B组为3%，两组对比差异无统计学意义(χ²=0.7341， P>0.05)。(3)两组患者术后1，6mo功能性滤过泡形成率：术后1mo A组为97%，B组为94%，两组对比差异无统计学意义(χ²=0.7301， P>0.05)； 术后6mo A组为88%，B组为86%，两组对比差异无统计学意义(χ²=0.8172， P>0.05)。

结论：在原发性急性闭角型青光眼患者行小梁切除术时，四针缝合的巩膜瓣在短期内可以较好的控制眼压，减少早期浅前房的发生率。

METHODS: Totally 60 cases(68 eyes)of confirmed primary acute angle-closure glaucoma were randomly divided into two groups. Group A(four-needle suture of scleral flap)were 30 cases(33 eyes). Group B(two-needle suture of scleral flap)were 30 cases(35 eyes). Postoperative intraocular pressure, anterior chamber depth and filtering bleb shape were compared. All cases were followed-up for 6 months.

RESULTS:(1)On the 2^nd postoperative day, compared intraocular pressure(IOP)of both groups, the difference was statistically significant(t = 5.8765, P <0 05); 2 weeks of post-operation, compared IOP of both groups, there was no statistically significant difference(t=1.2347, P>0.05); In the 1^st month after operation, compared IOP of both groups, the difference was not statistically significant(t=1.4350, P>0.05); In the 3^rd month postoperatively, compared IOP of both groups, the difference was not statistically significant(t=1.3548, P>0.05); 6 months after operation, compared IOP of both groups, there was no statistically significant difference(t=1.5753,P>0.05).(2)On the 2^nd postoperative day, the incidence rate of shallow anterior chamber in group A was 6%, and that of group B was 17%. Shallow anterior chamber in group A was mainly shallowⅠ. Compared the incidence rate of shallow anterior chamber between both groups, the difference was statistically significant(χ ²=6.4513, P<0.05); 1 week after operation, the incidence rate of shallow anterior chamber in group A was 0 and 3% in group B respectively. Compared the incidence rate of shallow anterior chamber between both groups, the difference was not statistically significant(χ ²=0.7341, P>0.05).(3)functional filtration bubble formation rate of patients of two groups in 1 month and 6 months postoperatively: that of 1 month after operation in group A was 97% and 94% in group B respectively, compared them between two groups, the difference was not statistically significant(χ ²=0.7301, P>0.05); That of 6 months after operation in group A was 88% and 86% in group B respectively, the difference was not statistically significant when compared them between two groups(χ ²=0.8172,P>0.05).

CONCLUSION: In primary acute closed-angle glaucoma underwent trabeculectomy, four stitches of the scleral flap can better control IOP in the short term, and reduce the incidence rate of early shallow anterior chamber.
