甲基纤维素在小梁切除术中应用的临床观察

目的评价甲基纤维素在闭角型青光眼小梁切除术中的疗效。方法采用随机对照法将85例（92只眼）原发性闭角型青光眼分为实验组和对照组。实验组采用小梁切除术联合甲基纤维素，对照组采用单纯小梁切除术。比较两组术后前房形成、眼压情况及滤过泡情况。结果所有病例平均随访6个月至1年，术后6个月两个组眼压正常及功能性滤过泡形成率分别为91．3％和78．8％，差异有显著性意义；浅前房的发生率实验组（4．5％）明显低于对照组（16．3％）。结论复合式小梁切除术可以调节房水滤过量，减少并发症的发生，提高手术成功率。

A clinical comparative study of the methylcellulose in trabeculectomy for primary acute angle closure glaucoma

Objective To evaluate to the efficacy of methylcellulose in trabeculec- tomy in treating primary acute angle closure glaucoma. Methods In a randomized control clinical trial,85 （92 eyes） with primary acute angle closure glaucoma were divided into study group and control group. The study group had applyed with methylceUulose and trabeculetomy and the control group had applyed with trabecule- ctomy. After trabeculectomy, depth of anterior chamber, postoperative lOP, filtration blebs and complications were followed up and com- pared. Results The follow-up ranged from 6 to 12 months. The success rates of functional filtering blebs and respect to IOP in two groups were 91.3%and 78.8%respectively. The difference being statisti- cally significant. The shallow anterior chamber of study group （4.5%） were much less than those of contrel group （16.3%）. Conclusion The compound trabeculeclomy adjusted the amount of aqueous humor out-flowing, decreased complications postoperative and elevated the rates of surgical success.
