    摘要:

    目的:研究人脐带静脉管(HUV)植入联合应用丝裂霉素C(MMC)在非穿透性小梁手术(NPTS)中应用的临床效果。方法:选取中、晚期原发性开角型青光眼病例32例(46眼)。患者分为两组:HUV+MMC组(n=25),透明质酸生物胶(SKGEL)+MMC组(n=21);行非穿透性小梁手术,HUV+MMC组将HUV置于巩膜床内,SKGEL+MMC组将SKGEL缝合固定于巩膜床上。术后分别于1,2,4wk;2,6,12mo裂隙灯下观察术口愈合情况、滤过泡情况、前房炎症反应、前房深度、有无出血等。测量眼压、最佳矫正视力,计算手术成功率。结果:HUA+MMC组的术后眼压平均在16mmHg,HUA+MMC组与SKGEL+MMC组在术后1,2,4wk;2,6,12mo时P>0.05,差异无显著性;功能性滤过泡术后1wk~12mo时HUA+MMC组与SKGEL+MMC组比较无显著性差异(P>0.05),末次随访HUA+MMC组成功(完全成功和条件成功)21眼,成功率84%;SKGEL+MMC组成功18眼,成功率86%。两组末次随访手术成功率比较无显著性差异(P>0.05)。结论:HUV联合MMC在NPFS中对术眼有明显而稳定的降压作用,大大提高了NPTS的手术成功率。脐带静脉管取材方便,抗原性低,有良好的组织相容性,眼局部反应轻,无毒副作用,且与SKGEL植入物相比,价格便宜,是理想的NPTS中的植入物。

    Abstract:

    AIM:To investigate the clinical therapeutic effects of human umbilical vein (HUV)implantation and mitomycin C (MMC) in non-penetrating trabecular surgery (NPTS).METHODS:A total of 32 patients (46 eyes) with uncontrolled primary open angle glaucoma (POAG) were divided into two groups: HUV+MMC group (n=25), SKGEL+MMC group (n=21). The procedure commenced with the creation of a limbus based conjunctival flap. After the dissection of a superficial limbus based rectangular scleral flap, MMC(0.4mg/mL) was used superior and inferior surface of the superficial scleral flap for three minutes. A second limbus based scleral flap was carefully dissected beneath the previous one towards the choroid. Schlemm’s canal was deroofed during the extension of the deep scleral flap toits limbal edges. HUV or SKGEL fixed on the bed of sclera in experimental group. Postoperative examinations were performed at 1 week,2,4 weeks;2,6,12 months. IOP,best-corrected visual acuity(BCVA), functional blebs and success rate were examined.RESULTS: There were no statistically differences with postoperative IOP in HUV+MMC group and SKGEL+MMC group (P>0.05) during 1 week to 12 months. There was no difference with postoperative function blebs and the change of BCVA during 1 week to 12 months between HUV+MMC group and SKGEL+MMC group (P>0.05).At 12 months after surgery, the success rate was 84% in HUV+MMC group,86% in SKGEL+MMC group.CONCLUSION: The application of HUV in NPTS can prevent the adhesion of filtering channel and it can improve the success rate of NPTS. Compared with SKGEL, HUV has lower price. So it is a better implant.
