Clinical analysis of trabeculectomy for primary acute angle-closure glaucoma with high intraocular pressure

Objective To evaluate the therapeutic efficacy and safety of trabeculectomy for primary acute angle-closure glaucoma with high intraocular pressure(IOP).Methods Fourty-eight cases(50 eyes) of primary acute angle-closure glaucoma were retrospectively analyzed,which underwent trabeculectomy.These cases were divided into 2 groups by the preoperational IOP: the operation group(12 eyes,IOP≥40mm Hg),and the control group(38 eyes,IOP40mm Hg).And the IOP,visual acuity,complications and surgery outcome of both groups were compared.Results No severe complications such as choroidal hemorrhage,malignant glaucoma were observed in both groups during surgery and postoperation.The success rate of operation in the control group was much higher than that in the operation group shortly after the operation with significant difference(P=0.033 2).But the success rate of both groups had no significant difference(P0.05) in return visit.Conclusion Trabeculectomy for primary acute angle-closure glaucoma with persistent high intraocular pressure should be performed actively to avoid further damage to the visual function.
