目的:探讨Ahmed青光眼引流阀植入术治疗难治性青光眼的手术方法及并发症预防。方法:回顾我院1999/2009年行Ahmed青光眼引流阀植入术治疗的难治性青光眼5例,对术前和术后视力、眼压、引流管位置、虹膜新生血管及术后并发症情况进行分析。结果:术前眼压:43.00±14.71mmHg,随访6～24mo,末次眼压为22.60±12.72mmHg。术后1例视力略有提高,3例视力无明显变化,1例视力下降。4例术后引流管位置良好,1例术后3mo接触角膜内皮。4例新生血管性青光眼中3例术后虹膜新生血管部分或全部消退,1例无消退。前房出血3例;前房纤维素性渗出4例;引流管口阻塞2例,1例经YAG激光治疗再开放,1例经抗炎治疗后再开放,但术后3mo又出现阻塞经治疗无好转;浅前房2例;前房消失和高眼压1例;引流管暴露1例。结论:Ahmed青光眼引流阀植入术是治疗难治性青光眼比较有效的方法,注意术中手术操作可以减少早期并发症的发生。

·AIM:To investigate the surgical skills and prevention of complications of Ahmed valve implantation for refractory glaucoma.·METHODS:This retrospective study reviewed the visual acurity,intraocular pressure(IOP)and complications in 5 refractory glaucoma patients with Ahmed valve implantation from 1999 to 2009.·RESULTS:In the follow-up examination of 6 to 24 months,the IOP was reduced from 43.00±14.71 to 22.60±12.72mmHg.Visual acurity improved in 1 case,continued in 3 cases and decreased in 1 case.The tubes were placed right in 4 cases,the other case touch to cornea.Iris neovascularization reduced in different degrees in 3 NVG.Complications included anterior chamber hemorrhage in 3 cases,anterior chamber fibrous exudation in 4 cases,tube blockage in 2 cases,shallow anterior chamber in 2 cases,anterior chamber disappearance and high IOP in 1 case in final,tube explosure in 1 case.·CONCLUSION:Ahmed glaucoma valve implant is an effective method for treating refractory glaucoma,and the surgical skills will reduce the incidence of early complicaions.·
