青光眼小梁切除术后低眼压浅前房的临床分析

Clinical analysis of shallow anterior chamber and low intraocular pressure after trabeculectomy

目的分析青光眼小梁切除术后低眼压浅前房的原因和处理。方法回顾性总结2006年1月至2010年4月在我院住院的行小梁切除术闭角型青光眼患者94例110眼发生低眼压浅前房的常见原因和处理探讨。结果 94例110眼小梁切除术后发生浅前房21眼,发生率为19.09%,眼压8mmHg至测不出,时间术后1-5天。其中滤过过畅9眼,42.86%,结膜瓣渗漏6眼,28.57%,脉络膜脱离6眼,28.57%。通过保守治疗19眼,手术治疗2眼。结论闭角型青光眼行小梁切除术,术后浅前房的发生率高,常见原因滤过过畅,脉络膜脱离和结膜瓣渗漏。大部分患者通过保守治疗治愈。

Objective To analyze the reason and management for shallow anterior chamber and low intraocular pressure after trabeculectomy. Methods The reason and management for shallow anterior chamber and low intraocular pressure after trabeculectomy in 94 cases of close-angle glaucoma（110 eyes） from Jan, 2006 to Apr, 2010, were retrospectively analyzed. Results Shallow anterior chamber occurred in 21 eyes（19.09%）, while the intraocular pressure was below 8 mmHg. Filtering too smooth occurred in 9 eyes（42.86%）, conjunctiva flap leakage in 6 eyes（28.57%）, and choroids detachment in 6 eyes（28.57%）. 19 eyes were treated conservatively, while 2 eyes by operation. Conclusion The incidence of shallow anterior chamber was high in angle-closure glaucoma. Most common reasons were filtering too smoothly, conjunctiva flap leakage and choroids detachment. Most cases could be cured by conservatively treatments.
