Abstract: Objective:To investigate the efficiency of travoprost in lowering patients intraocular pressure who contained angle-closure glaucoma even after phacoemulsification and goniosynechialysis.Methods:Eleven angle-closure glaucoma patients whose intraocular pressures were not ideal after phacoemulsification and goniosynechialysis were selected.Four weeks after surgery,the intraocular pressure was measured,and the eyes were treated with 0.004% travoprost once every night.Intraocular pressure at 9am and 16pm,visual acuity,and visual field were checked at the first,second,forth week after travoprost treatment.Finally,the intraocular pressure values after treatment were compared with before treatment.Results:In contrast to before treatment of travoprost,at the first,second,forth weeks after treatment,the average intraocular pressure was reduced obviously(P0.01).Conclusions:Travoprost was safe and effective in treatment of angle-closure glaucoma after phacoemulsification and goniosynechialysis.
