隧道刀制作巩膜瓣在小梁切除术中的应用研究

Study of the application of scleral flap made by tunnel knife in trabeculectomy

目的:前瞻性、完全随机对比研究用隧道刀制作巩膜瓣在以穹窿部为基底结膜瓣小梁切除术的疗效及并发症。方法:完全随机方法将拟手术的青光眼病人分至两组,分别施行以穹窿部为基底结膜瓣,隧道刀制作巩膜瓣的小梁切除术(A组)及以角膜缘为基底结膜瓣,常规方法制作巩膜瓣的复合式小梁切除术(B组),术后观察6月,比较两组术后疗效及并发症。结果:两组的成功率分别为75%,70%,其差别没有显著性差异;两组均未出现严重并发症,其并发症发生率相近。结论:采用隧道刀制作巩膜瓣在以穹窿部为基底结膜瓣小梁切除术中可有效简化青光眼手术过程。

Objective：To study the effect and complication of trabeculectomy with scleral flap made by tunnel knife in prospective randomized clinical trial. Methods：A total of 40 glaucoma eyes were divided into two groups by randomized method, Trabeculectomy was performed with fornix-based flaps, and scleral flaps made by tunnel knife （group A）; or limbus-based flaps, and scleral flaps made by general method（group B） respectively. The samples were observed for 6 months after operation and the effect and complication of the two groups were compared. Results：There was no significant difference between group A and B in success rate, which were 75% and 70% respectively;and the conditiong of complication was the same. Conclusion：It can effectively simplify the procedure of fornix-based flaps trabeculectomy with scleral flaps made by tunnel knife.
