小梁切除术后浅前房原因分析

Causes of shallow anterior chamber after glaucoma trabeculectomy

目的:探讨小梁切除术手术后浅前房发发生原因及处理原则。方法:分析小梁切除术手术患者182例308眼发生浅前房的比率及处理方法。结果:小梁切除术术后浅前房38例42眼(13.6%),其中引流过畅21眼、脉络膜脱离17眼,结膜瓣渗漏2眼,恶性青光眼2眼,33眼行保守治疗(78.6%),7眼行前房重建术,1眼行结膜瓣修复,1眼行晶状体摘除术及玻璃体抽吸术。结论:小梁切除术术后浅前房发生率较高,其最常见原因为脉络膜脱离及房水引流过畅,大多数浅前房通过非手术治疗,在前房重建中效果良好。

AIM ： To investigate the causes and treatment of shallow anterior chamber after glaucoma trabeculectomy. ~ METHODS： The ratio and management of 182 cases （308 eyes） with shallow anterior chamber after glaucoma trabecuiectomy were analyzed. RESULTS： Of 308 eyes, 42 eyes （13.6%） appeared shallow anterior chamber after glaucoma trabeculectomy, in which 21 eyes were with excessive titration, 17 eyes with choroidal detachment, 2 eyes with filter bleb leaks, and 2 eyes with malignant glaucoma. Thirty-three eyes （78.6%） underwent conservative treatment, 7 eyes by anterior chamber reconstruction, 1 eye by conjunctival flap repairing, and 1eye by lens extraction and vitreous aspiration. CONCLUSION： The results show that the ratio of shallow anterior chamber after glaucoma trabeculectomy is high and the main causes are excessive titration and choroidal detachment. Most of shallow anterior chamber can be treated by non-operative treatment and get good effects in reconstruction of anterior chamber
