Ahmed青光眼引流阀植入术治疗玻璃体切割术后青光眼的临床研究

Ahmed glaucoma valve implantation in treatment of twelve eyes with glaucoma after vitrectomy:a clinical study

目的探讨Ahmed青光眼引流阀植入术治疗玻璃体切割术后青光眼的疗效及其安全性。方法对12例(12眼)因视网膜脱离已行玻璃体切割术后发生青光眼的患者行Ahmed青光眼引流阀植入术,术后随访3～6个月,平均为(4.7±1.2)个月。结果12眼术前眼压为30.5～50.7 mmHg(1 mmHg=0.133 kPa),平均为(40.5±10.2)mmHg;术后随防期内,眼压为8.0～21.0 mmHg,平均为(13.5±4.3)mmHg。手术成功率为100%。除2眼在术后2周时因引流管阻塞而行冲洗再通外,无其他术后并发症发生。结论对于玻璃体切割术后药物无法有效控制眼压的青光眼患者,Ahmed引流阀植入术是一种有效、安全的治疗方法。

Objective To evaluate the efficacy and safety of Ahmed glaucoma valve implantation for glaucoma following vitrectomy surgery.Methods Twelve patients（12 eyes） who had been diagnosed with glaucoma after vitrectomy and phacoemulsification surgery due to retina detachment were selected in this study.The 12 eyes were treated with Ahmed glaucoma valve implant surgery,and the patients were followed up for（4.7±1.2） months（ranging 3-6 months）.Results The mean intraocular pressure decreased from（40.5±10.2） mmHg（1 mmHg=0.133 kPa） before the implant surgery（ranging 30.5-50.7 mmHg） to（13.5±4.3） mmHg after the surgery（ranging 8.0-21.0 mmHg）.The successful rate of the implant surgery was 100%.Two eyes had obstruction of drainage tube 2 weeks after the surgery and were recanalized after rinsing,with no other complications.Conclusion Ahmed glaucoma valve implant is effective and safe for glaucoma after vitrectomy.（Shanghai Med J,2010,33： 191-193）
