青光眼小梁切除术后浅前房原因分析及处理

目的探讨青光眼小梁切除术后浅前房与术前眼压、术后结膜伤口渗漏、滤过过强及脉络膜脱离的关系。方法回顾性总结行青光眼小梁切除术后172例(189眼)术后发生浅前房的情况。结果发生浅前房41眼(21.69%)。术前眼压≤21mmHg者146眼中发生浅前房17眼(11.64%),术前眼压22~35mmHg者32眼发生浅前房13眼(40.62%),术前眼压≥35mmHg者11眼中发生浅前房6眼(54.54%)。术后结膜瓣渗漏11眼(26.83%),滤过过强24眼(58.53%),脉络膜脱离5眼(12.19%),恶性青光眼1眼(2.44%)。结论青光眼小梁切除术后浅前房与多种因素有关:①术前眼压控制正常者,发生率低;②以滤过过强性者为最多。

The reasons analysis and treatment of shallow anterior chamber after trabeculectomy

Objective To explore the relationship between postoperative shallow anterior chamber and preoperative intraocular pressure, leakage of conjunctive incision, filtering much more and detachment of choroid postoperatively. Methods Review which occured postoperative shallow anterior chamber in172 patients(189 eyes)of different kinds of glaucoma. Results All of the posteroperative shallow anterior chamber occured in 41eyes (21.69%). 17eyes in 146 eyes (11.64%)occured shallow anterior chamber with equal or below 21mmHg preoperative intraocular pressure.13 in 32 eyes(40.62%) with preoperative intraocular pressure of 22~35mmHg occurred. 6 in 11eyes(54.54%) with preoperative intraocular pressure equal or over 35 mmHg occurred. Eyes were because of conjuntive leakage postoperatively. Eyes were because of much more filering. Eyes were related with the detachment of choriod and other 1eye was caused by malignant glaucoma. Conclusions Shallow anterior chamber after trabeculectomy had relationship to many kinds of factors. The better control of the preoperative intraocular pressure the less occure of the postoperative shallow anterior chamber. The most cause of postoperative shallow anterior chamber is much more filtering.
