【摘要】 目的:评价Ahmed青光眼引流装置植入术与传统小梁切除术(Trab)治疗难治性青光眼的疗效。方法:运用Cochrance系统评价方法,使用相关数据库检索关于Ahmed引流阀植入术与传统Trab术治疗难治性青光眼效果比较的随机对照试验(RCT)文献。观察两种手术的眼压下降幅度百分比(IOPR%)及使用与未使用抗青光眼药物达到目标IOP成功率。结果:共293例患者(293只眼)被纳入此次Meta分析,其中Ahmed组146只、Trab组147只;两组术后随访结束时IOPR%比较,差异无统计学意义[MD=-0.59,95%CI=(-7.48,6.29),P>0.05];术后1年无论是否抗青光眼药物,Trab组达到目标IOP成功率均低于Ahmed组(P<0.05)。结论:在治疗青光眼的手术中,传统Trab术与Ahmed引流阀植入术组有相似的降低IOP效果,但Ahmed引流阀植入术达到目标IOP成功率较高。

【Abstract】 Objective:To evaluate the efficacy of Ahmed glaucoma drainage device implantation and trabeculectomy(Trab)in treatment of refractory glaucoma.Method:The Cochrance system evaluation method was used to retrieve the literature of randomized controlled trials(RCT)on the efficacy of Ahmed drainage valve implantation compared with traditional Trab in treatment of refractory glaucoma.The IOP reduction rate(IOPR%)and the success rate of IOP with or without antiglaucoma drugs were observed.Result:A total of 293 patients(293 eyes)were included in the Meta-analysis,included 146 in Ahmed group and 147 in Trab group.At the end of follow-up,the IOPR% in two groups was compared,the differences was not statistically significant[MD=-0.59,95% CI=(-7.48,6.29),P>0.05].After surgery 1 year,whether or not anti-glaucoma drugs were used,The successful rate of achieving IOP of Trab group were lower than those of Ahmed group(P<0.05).Conclusion:In glaucoma surgery,traditional Trab and Ahmed drainage valve implantation have similar effect in reducing IOP,but the success rate of Ahmed drainage valve implantation is higher.

难治性青光眼是指传统的滤过手术或联合抗代谢药物和最大耐受性抗青光眼药物难以控制眼压(IOP)的正常范围,难治性青光眼的治疗一直是较为困难的问题之一。在眼科临床工作中,一些患者经常多次手术仍不能控制IOP的增加,医疗器械制造商和临床的眼科医生一直在不断努力,并积极探索治疗青光眼及其房水引流。近年来,房水引流装置在难治性青光眼的治疗中取得了突破性进展,随着局部药物代谢的应用和外科技术的提高,难治性青光眼的手术成功率也随之提高[1]。在临床治疗青光眼中,最常用的方法是小梁切除术(Trab)及青光眼引流阀。近年来,Trab术成功率较低的问题愈发明显,因此引流阀越来越多地应用于传统手术成功率低的患者。引流阀降低IOP的机制为通过前房引流管将房水引流至眼球赤道部的结膜下外植体处,随后由周边的毛细血管及淋巴管吸收[2]。其特……
