Ahmed 青光眼引流阀植入术治疗难治性青光眼

Clinnical experience of Ahmed valve implantation for refractory glaucoma

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2007～2012年行Ahmed青光眼引流阀植入术治疗难治性青光眼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：45．00±13．82mmHg ，随访6～24mo ，末次眼压为22．30±11．75mmHg。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。术后并发症主要是早期的短暂性浅前房和高眼压，前房积血，以及晚期的滤过通道瘢痕纤维化。结论Ahmed青光眼引流阀植入术是治疗难治性青光眼较有效的方法。注意术中手术操作可以减少早期并发症的发生。

Objective To investigate the surgical skills and prevention of complications of Ahmed valve implantation for refractory glaucoma .Methods Five patients underwent Ahmed glaucoma a valve implantation were summarizedretrospectively .The visual acuity ,intraocular pressure （IOP） ,postoperative complications and the effective rate were observed comparatively .The mean period of follow-up was 6-24 months .Results In the follow-up examination of 6 to 24 months ,the IOP was reduced from 45 .00 ± 13 .82 to 22 .30 ± 11 .75mmHg .Visual acurity improved in 1 case ,continued in 3cases and decreased in 1case .The common postoperative complications included transient flat anterior chamber and high intraocular pressure in early stage ,hyphema and fibrination in late stage .Conclusion Ahmed glaucoma valve implant is an effective method for treating refractory glaucoma ,and the surgical skills will reduce the incidence of early complications .
