【摘要】 目的 观察传统小梁切除术治疗原发性开角型青光眼时不同大小的矩形巩膜瓣与术后浅前房的关系。方法 121例(140眼)原发性开角型青光眼患者进行小梁切除术， 术中选用不同大小巩膜瓣， 分析并总结巩膜瓣大小与术后浅前房的关系。结果 a型瓣有浅前房17眼， b型瓣有浅前房6眼， 比较差异具有统计学意义(P<0.05)；a型瓣与b型瓣术后浅前房分布情况比较差异有统计学意义(P<0.05)。结论 巩膜瓣大小不同， 术后浅前房的几率不同， 较大的瓣产生浅前房的机会较小。

    【Abstract】 Objective To observe relationship between different rectangular scleral flap size in trabeculectomy for primary open-angle glaucoma and postoperative shallow anterior chamber. Methods A total of 121 (140 eyes) patients with primary open-angle glaucoma received trabeculectomy by different rectangular scleral flap size. Analysis and summary were made on relationship between scleral flap size and postoperative shallow anterior chamber. Results There were 17 eyes with shallow anterior chamber in type a flap and 6 eyes in type b flap. Their difference had statistical significance (P<0.05). The difference of postoperative shallow anterior chamber distribution had statistical significance between type a and b flaps (P<0.05). Conclusion Different scleral flap size leads to different incidence of postoperative shallow anterior chamber. Larger flap leads to low incidence of shallow anterior chamber. ......
