【摘要】 [目的 ]探讨青光眼小梁切除术后前房形成迟缓的原因及处理方法 ,掌握其临床规律。 [方法 ]青光眼小梁切除术 1 2 6例 1 5 1眼。术中在显微镜下做以穹隆为基底结膜瓣 ,做约 5mm× 4mm长方形 1 / 2厚板层巩膜瓣。前房穿刺缓慢放出房水 ,切除小梁组织约 3mm× 1mm ,剪除根部虹膜 ,缝合结膜瓣。庆大霉素 2万u +地塞米松 2mg结膜下注射。 [结果 ]前房形成迟缓共 32眼(2 9例 ) ;其中I度 2 3眼 ,II度 7眼 ,III度 2眼。发生率为 2 1 .2 %。 [结论 ]1 )青光眼滤过手术后 ,多数 7d内自然形成前房 ,若迟缓形成 ,对于I度、II度浅前房先行保守治疗 ,减轻炎症的同时 ,前房多可自行恢复。对于III度浅前房 ,先行保守治疗 ,无效后行前房注气成形术或激光虹膜周边切除术可恢复前房。 2 )前房迟缓形成的最常见原因为引流过畅所至。更多还原

【Abstract】 To analyze the cause and management of shallow anterior chamber after trabeculectomy of glaucoma. 126 cases(151 eyes) were operated with routine trabeculectomy of glaucoma. 29 cases(32 eyes) with the postoperative complication of shallow anterior chamber, the incidence rate was 21.2%. The depth of shallow anterior chamber has been classified according to Spaeth Classification.Shallow anterior chamber grade I in 23 eyes, grade II in 7 eyes,grade III in 2 eyes. Of all the 32 eyes, 22 eyes with much more filtering, 2 eyes with conjunctival flap flushing, 7 eyes choroidal detachment. They were managed with non-surgical therapy.1 eye with malignant glaucoma,it was managed with surgical therapy. [Conclusions]The common cause of shallow anterior chamber after trabeculectomy is excessive aqueous homor drainage . Through conservative treatment, most patients with shallow anterior chamber grade I - II can be cured.Shallow anterior chamber grade III can be cured through surgical therapy.更多还原
