Clinical observation on application of adjustable sutures in trabeculectomy

Abstract

Objective To evaluate the effect of application adjustable sutures in trabeculectomy in treating primary angle closure glaucoma. Methods The 185 cases(210 eyes) with primary angle closure glaucoma were randomly divided two groups. Control group 73 cases (83 eyes) underwent conventional trabeculetomy. Observation group 112 cases(127 eyes) underwent trabeculectomy, combined with application of adjustable sutures. To compare the postoperative occurrence of shallow anterior chamber and IOP and functional filterling belbs and to analysis. Results There were 16 eyes postoperative shallow anterior chamber in control group (19.28%) while 12 eyes in observation group (9.45%), the statistic difference was significant(χ2 = 5.28, P 0.05).One year after operation, IOP control rate was 72.22% in control group, observation group 89.29%, the statistic difference was significant(χ2=6.83,P<0.01);the functional filterling belbs was 79.63% in control group, 97.67% in observation group, the statistic difference was significant(χ2= 4.30,P<0.05). Conclusion The adjustable sutures in trabeculectomy is better than conventional trabeculectomy. Key words: adjustable suture; trabeculectomy; glaucoma
