目的:探讨青光眼复合式小梁切除术后浅前房发生的原因及处理方法。方法:对64例103眼复合式小梁切除术后浅前房18眼进行原因分析及治疗效果观察。结果:浅前房18眼,滤过过强、结膜瓣渗漏、脉络膜脱离及睫状环阻塞性青光眼是小梁切除术后浅前房的主要原因。14眼经非手术治疗前房恢复,4眼手术后恢复。结论:注意术前降眼压和术中准确操作可减少浅前房的发生。 Objective: To investigate the causes of shallow anterior chamber after trabeculectomy combined with glaucoma treatment. Methods: The etiology and treatment of 64 cases with 103 eyes of shallow anterior chamber after composite trabeculectomy were observed. Results: Eighteen cases of shallow anterior chamber, excessive filtration, conjunctival flap leakage, choroidal detachment and ciliary loop obstruction were the main causes of shallow anterior chamber after trabeculectomy. Fourteen eyes underwent nonsurgical treatment of anterior chamber recovery and four had postoperative recovery. Conclusion: Note preoperative intraocular pressure and intraoperative accurate operation can reduce the incidence of shallow anterior chamber.
