Clinical study of modern trabeculectomy

Objective To investigate the clinical effect of about modern trabeculectomy.Methods The patients of primary open angle glaucoma and chronic angle closure glaucoma were divided into two groups randomly.Modern trabeculectomy group contained 61 cases (120 eyes).The control group contained 65 cases (113 eyes) received conventional trabeculectomy. The average follow-up period was 6 to 12 months postoperatively.Results The postoperative intraocular pressures (IOP) were significantly lower than the preoperative IOPS in both groups. While the IOPS on the 7th day after the surgery between the two groups had no statistical significant difference. The average postoperative IOP at the 6th month in the Modern group was 14.34± 3.95 mmHg and 19.57± 7.76 mmHg in the control group, which were statistical significant difference (P<0.05). The incidence rate of shallow anterior chamber in the control group was higher than that in the modern group (P<0.05).Conclusions Modern trabeculectomy has the advantages of preventing postoperative shallow anterior chamber filtering belbs and achieving better control of postoperative IOP over the conventional trabecule-clomy in primary open angle glaucoma and chronic angle closure glaucoma.
