两种植入物在非穿透性小梁手术中的应用

Clinical application of two different drainage implants in non-penetrating trabecular surgery

目的 :探讨非穿透性小梁切除术 (NPTS)联合不同植入物的方法及疗效。方法 :将 31例 (40只眼 )原发性开角型青光眼随机分为A、B两组 ,每组均为 2 0只眼。A :NPTS +保存羊膜植入。B :NPTS +透明质酸钠生物胶 (SKGEL)。所有眼联合MMC及调整缝线 ,观察术后眼压、视力、滤过泡、前房等。结果 :随访一年 ,手术成功率 :A组 85 % ,B组 90 % ,A、B两组无显著性差异 (X2 =0 39P >0 5 )。所有患者无前房变浅、炎症、脉络膜脱离、视力下降等并发症。结论 :NPTS植入物可选择羊膜及SKGEL ,但羊膜更经济。

Objective:To evaluate the clinical efficacy of nonpenetrating trabeular surgery (NPTS) with different drainage implants.Methods:We randomly divided 31 cases(40 eyes) of primary open-angle glaucoma into two gruops each 20 eyes.Group A:NPTS and amniotic membrane transplantation.Group B:NPTS and reticulated hyaluronic acid.All surgical eyes used MMC and removable suture.Postoperatively,intraocular pressure (IOP),anterior chamber reactions and the bleb appearance were observed.Results: The mean follow-up was one year .The successful rate of Group A and Grcup B was 85%,90%,respectively.There are no difference between Group A and Group B( X 2=0.39, P >0.5).The complications such as flat chamber,inflammation reaction and choroidal detachment were not observed.The visual acuity remained unchanged.Conclusions:Amniotic membrane and hyaluronic acid gel can be used for NPTS drainage implants.The amniotic membrane is cheaper substitude for hyaluronic acid gel.
