小梁切除术中无暴露线结的巩膜瓣可拆除缝线法临床观察

Trabeculectomy with removable and nonexposure knot sutures

目的对小梁切除术中应用无暴露线结的巩膜瓣可拆除缝线法与传统的小梁切除术的术后并发症、疗效进行分析。方法７１例（８０眼）首次行小梁切除术患者分为２组，可拆除缝线组３５例（４０眼），术中应用双臂一体无暴露线结的巩膜瓣可拆除缝线；对照组３６例（４０眼）行传统的小梁切除术。结果术后浅前房发生率，可拆除缝线组７．５％（３眼），对照组２７．５％（１１眼）（Ｐ＜０．０５）。随访至术后６个月，２组手术成功率分别为：８７．５％和８５％（Ｐ＞０．０５），但可拆除缝线组术后眼压比对照组更低（Ｐ＜０．０５）。结论该技术能在小梁切除术后早期灵活地控制滤过量，明显减少了术后因滤过强所致的浅前房。

ObjectiveTo compare the postoperative complications and effects of traditional trabeculectomy and the trabeculectomy with removable and nonexposure knot suture method.Methods71 cases (80 eyes) with the first trabeculectomy were divided into 2 groups.35 cases (40 eyes) with scleral flap two arm removable and nonexposure knot were the treated group,while 36 cases (40 eyes) with traditional trabeculectomy were used as control group.Results7.5%(3 eyes) developed postoperative shallow anterior chamber in the treated group,but this occured in 27.5% (11 eyes) of the control group ( P <0.05).The success rate of 2 groups were 87.5% and 85%,respectively 6 mon after operation ( P >0.05).The intraocular pressure was lower in treated group than that of control group ( P <0.05).ConclusionIt is believed that the new technique used in treated group can effectively control postoperative outflow and reduce the chance of shallow anterior chamber due to strong outflow,and keep intraocular pressure at a low level.
