AIM:To discuss the clinical curative effect of modified trabeculectomy for glaucoma. METHODS:A total of 40 cases with glaucoma were randomly divided into control group and treatment group, 20 cases in each group . Modified trabeculectomy was performed in treatment group , whereas the control group undertook trabeculectomy. Intraocular pressure(IOP), vision and the depth of anterior chamber were compared after operation. RESULTS:Postoperatively,IOP, vision and the depth of anterior chamber in treatment group were obviously better than the control group, with statistical significance(P<0.05). CONCLUSION:Modified trabeculectomy for glaucoma can reduce complications,which is worth promoting.
