Vitreous aspiration combined with intracameral air injection for acute angle-closure glaucoma with extremely shallow anterior chamber

Objective To explore the efficiency of vitreous aspiration and intracameral air injection for acute angle-closure glaucoma with extremely shallow anterior chamber and persistent ocular hypertension.Methods Retrospective analyzed 15 eyes of angle closure glaucoma with extremely shallow anterior chamber in 15 patients.The intraocular pressure was above 60mmHg after 24 hours of routine therapy.The patients underwent vitreous aspiration via pars plana combined with intracameral air injection under local anesthesia.Pre-operation and post-operation intraocular pressure,visual acuity,angle of anterior chamber was recorded and compared.Results The intraocular pressure of 15 eyes in 15 cases of patients was all above 60mmHg,the visual acuity ranged from light perception to 0.02.In the first day after operation,The intraocular pressure in 13 eyes were under 21mmHg,2 eyes were ranged from 21mmHg to 30mmHg,10 cases of visual acuity ranged from 0.2 to 0.5,4 eyes from 0.1 to 0.2,the angle opens from 4 to ll o'clock,there were 11 eyes above 6 o'clock.Conclusions Vitreous aspiration can decrease intraocular hypertension,protect visual function markedly,and provide safe condition for various operations for glaucoma.Intracamel injection can open chamber angle efficiently,reduce the rate of filtering surgery.Vitreous aspiration combined with intracameral air injection can provided the patients efficient and timely therapy which worthy of recommending in clinical application.
