Ahmed引流阀植入治疗难治性青光眼的临床研究

Ahmed valve implantation for refractory glaucoma

摘要:

目的：探讨Ahmed引流阀植入治疗难治性青光眼的临床效果。方法：对61例（63眼）难治性青光眼的病人施行Ahmed青光眼引流阀植入手术，随访24月观察术后的眼压变化及并发症的发生情况。结果：术后1月，63眼的眼压变化从术前眼压（43.53±6.42） mmHg 降到（16.29±4.02） mmHg，成功率达到88.9%；而随访达12月的有44例，这部分病人术后眼压平均为（17.16±5.05） mmHg，成功率达84.1%。术后并发症包括浅前房、前房出血、脉络膜脱离、引流管内口堵塞、引流管与角膜接触等等。结论：Ahmed青光眼引流阀植入手术是难治性青光眼一种有效的治疗方法，值得在临床上广泛推广。

Abstract:

Objective：To explore the clinical efficacy of Ahmed valve implantation in the treatment of refractory glaucoma. Methods：Totally 61 patients（63 eyes） with refractory glaucoma underwent surgery using Ahmed glaucoma valve. Changes of intraocular pres－sure and postoperative complications were observed. Follow-up was lasted for 24 months. Results：At one month postoperatively，in－traocular pressure（n=63） was changed from （43.53±6.42） mmHg to （16.29±4.02） mmHg and the success rate was 88.9%. For those eyes with the follow-up≥12 months（n=44），intraocular pressure was （17.16±5.05） mmHg and the success rate was 84.1%. Common postoperative complications included：shallow anterior chamber，hyphema，choroidal detachment，tube blockage，tube-endothe－lial touch，etc. Conclusion：Ahmed valve implantation is one of the effective methods for refractory glaucoma and this method can be widely used in clinics.
