简介:目的探讨在持续性高眼压状态下行改进的小梁切除术的安全性及临床治疗效果。方法对49例(51眼)持续性高眼压状态的急性闭角型青光眼行如下改进的小梁切除术:1.术中先行前房穿刺并多次放液降压,2.隧道刀制作薄层大巩膜瓣并紧密缝合,3.术中散瞳、术毕皮质类固醇结膜下注射等。回顾性分析手术前后眼压控制情况、视力变化及手术并发症。结果术后观察随访1-6个月,眼压控制≤21mmHg者4611~:,术后视力较术前提高者42眼。本组病例均未出现脉络膜下爆发性出血、脉络膜脱离、恶性青光眼等严重术中、术后并发症。结论对持续高眼压状态的青光眼应积极手术治疗,改进后的小粱切除术可以取得满意疗效,并有效预防和减少并发症的发生。
