目的：探讨Ahmed青光眼阀植入治疗难治性青光眼的临床疗效。 方法：回顾性研究我院Ahmed青光眼阀植入术治疗21例21眼难治性青光眼的临床疗效并进行总结分析。 结果：术前平均眼压为44.6±7.2mmHg，术后6mo末次随访平均眼压15.4±5.3mmHg；视力提高4眼，无改变14眼，降低3眼；手术并发症主要包括术后前房形成迟缓2眼、持续高眼压1眼、引流管暴露1眼、角膜失代偿1眼、引流盘纤维包裹3眼；手术成功率为86％。 结论：Ahmed青光眼阀植入术是治疗难治性青光眼有效和安全的方法。

AIM: To explore the clinical efficacy of the Ahmed glaucoma valve implantation for refractory glaucoma. METHODS: The clinic outcomes of 21 cases (21 eyes) with refractory glaucoma were reviewed,all patients underwent the placement of Ahmed glaucoma valve implant. RESULTS:The mean preoperative intraocular pressure(IOP) was 44.6±7.2mmHg. Postoperative 6 months at the last follow-up mean IOP was 15.4±5.3mmHg; Comparing than the preoperative visual acuity, 4 eyes increased, 14 eyes had no changes and 3 eyes decreased. The main postoperative complications included postoperative shallow anterior chamber (2 eyes), retained high IOP (1 eye), tube blockage (1 eye), corneal decompensation (1 eye) and fiber wrap of drainage tray (3 eyes). The procedural success rate at 6 months was 86%. CONCLUSION: Ahmed glaucoma valve implantation may be an effective procedure for refractory glaucoma.
