Clinical observation of performing trabeculectomy on persistent high intraocular pressure in primary angle closure glaucoma

Objective To observe the safety and clinical curative effect of trabeculectomy on continuous high intraocular pressure in primary angle closure glaucoma.Methods A retrospective analysis of 33 cases (33 eyes) (IOP≥40mmHg) in patients with high intraocular pressure performed trabeculectomy (treatment group),37 cases (37 eyes) (IOP＜40mmHg) underwent trabeculectomy (control group),were compared between the two groups of patients with preoperative and postoperative visual acuity,intraocular pressure,filtering bleb and anterior chamber formation condition.Results No choroidal fulminant hemorrhage,retinal hemorrhage,severe complications such as malignant glaucoma occurred on two groups.There were no significant differences (P ＞0.05) on intraocular pressure,visual acuity,filtering blebs,and anterior chamber on both groups.Conclusions Persistent high intraocular pressure (full medication treatment for 24-72 hour,IOP is still ≥40mmHg) of primary angle closure glaucoma patients,actively take operation therapy,can not only shorten the course of disease,but also to avoid further damage to visual function,is safe and effective.
