目的:运用青光眼降压阀植入手术治疗难治性青光眼,建立有效的滤过通道,提高手术成功率。方法:选用标准Ahmed青光眼阀(AhmedGlaucomaValveAGV),为18例诊断明确的临床难活性青光眼志者治疗,术后眼压控制在8mmHg-10mmHg为手术成功标准,辅助以局部用药眼压控制为基本成功。术后随访1个月-18个月;结果:临床18例患者,术后眼压达到治疗目的16例,并发症及手术失败原因主要表现为前房出血、浅前房、引流管阻塞、葡萄膜炎。术后长期并发症为引流管移位及外露;结论:采用AGV植入物治疗难治性青光眼,利于引流房水的扩散。开放压稳定,能有效的阻滞因房水引流过畅而出现浅前房。是临床上治疗难活性青光眼值得推广的有效方法之一。
Objective: To use glaucoma valve implantation surgery for refractory glaucoma, to establish an effective filtration channel, to improve the success rate of surgery. Methods: The standard Ahmed glaucoma valve (AhmedGlaucomaValveAGV), 18 cases of clinically diagnosed clinically refractory glaucoma treatment, intraocular pressure control at 8mmHg-10mmHg for the success of surgery standards, assisted by topical intraocular pressure control as the basic success. The patients were followed up for 1 month to 18 months after operation. RESULTS: Among the 18 patients, the intraocular pressure (IOP) reached the goal of treatment in 16 cases. The main causes of complications and surgical failure were anterior chamber hemorrhage, shallow anterior chamber, drainage tube obstruction, Membranous inflammation. Postoperative long-term complications of drainage tube displacement and exposure; Conclusion: AGV implant treatment of refractory glaucoma, conducive to the drainage of aqueous humor. Open pressure stability, can effectively block due to drainage of aqueous humor and appear shallow anterior chamber. It is one of the effective methods to treat refractory glaucoma.
