小梁切除术失败原因的临床分析

A clinical analysis of the failure causes of trabeculectomy

目的:为寻找小梁切除术后眼压不降的原因。方法:对小梁切除术137例159眼做了回顾性分析。结果:发现术后高眼压19例21眼,发生率13.21%,其中有滤口但无滤泡的8眼占38.1%;滤口被血凝块及结蹄组织阻塞的5眼占23.81%;有滤口有滤泡的今眼占19.05%;滤口被虹膜、晶体阻塞各一眼各占4.76%;既无滤口也无滤泡的2眼占9.52%。结论:小梁切除术后眼压不降主要由于滤口、滤道阻塞,滤泡功能低下引起,分析其好发因素有助于我们今后预防和处理此类问题。

Purpose: To determine the causes of high intraocular pressure post-trabeculec-tomy. Methods. A restropective analysis of 159 eyes of 137 cases with trabeculec-tomy was made. Results. High intraocular pressure was recorded postoperatively in 21 eyes of 19 cases. The incidence was 13.21%. Among them, There were 8 eyes (38.1%) with filtering hole but without filtering bleb. 5 eyes (23.81%) with filtering hole blocked by clots and fibrotic tissues. 4 eyes (19.05%) with both filtering hole and bleb. 1 eye (4.76%)with filtering hole blocked by iris, 1 eye (4.76%) with filtering hole blobked by lens. 2 eyes with neither filtering hole nor bleb. Conclusion. High intraocular pressure post-trabeculec-tomy mainly is resulted from filtering hole, filtering path blocking, and under function of filtering bleb. To analyze the factors is useful for us to prevent and treat this kind of problem s in the future.
