巩膜隧道刀在小梁切除术中的应用

The application of the sclera tunnel knife in the glaucoma trabeculectomy

目的:探讨巩膜隧道刀在小梁切除术中的临床意义。方法:采取随机分组法,将42例(58只眼)原发性闭角型青光眼分为治疗组29只眼和对照组29只眼,前者为巩膜隧道刀制作巩膜瓣的青光眼小梁切除术,后者为常规青光眼小梁切除术。结果:治疗组与对照组对比,每眼术程所需时间短,术后散光小,副损伤小,术后并发症少。结论:应用巩膜隧道刀可以安全、快速、有效地完成小梁切除术。

Objective: To probe into the clinical results of the sclera tunnel knife in the glaucoma trabeculectomy. Methods: In a randomized control clinical trial, 58 eyes of 42 patients with primary angle closure glaucoma were divided into two groups, with group I consisting of 29 eyes and group II consisting of 29 eyes as control. The sclera flap was made with sclera tunnel knife in glaucoma trabeculectomy in group I, while the routine glaucoma trabeculectomy was used in group II. Results: Compared with the control group (group I), group I showed the shorter operation duration of each eye, less post-operative astigmatism, less secondary damage and fewer post-operative complications. Conclusion: It is safe, quick and effective to use the sclera tunnel knife in the glaucoma trabeculectomy.
