Clinical study on the therapeutic alliance of acute angle-closure glaucoma with cataract

Abstract

Objective To investigate the clinical significance of phacoemulsification combining initial iridoplasty by krypton and iridectomy by Nd:YAG laser treatment for cataract with acute angle closure glaucoma. Methods twenty-five eyes of 25 cases with first attack of acute angle-closure glaucoma with cataract were treated by initial laser iridoplasty and iridectomy after intraocular pressure controlled equability,followed by phacoemulsification and intraocular lens implantation after 3-14 days. The intraocular pressure,anterior chamber depth, visual acuity were observed, and the appearance of anterior chamber angle were found by Stratus OCT. Results From initial condition to after-operation, Intraocular pressure was decreased obviously from 62.17 ± 14. 12 mmHg to 14.32 ± 3. 17 mmHg. Anterior chamber depth changed from 1.67 ± 0.32 mm to 2.86 ± 0.40 mm, and the anterior chamber angle open widely. All patients had improved visual acuity. Conclusions To attack of acute angle-closure glaucoma combined with cataract, laser iridoplasty and iridectomy with followed phacoemulsification can effectively control the intraocular pressure,open the angle of anterior chamber, and improve visual acuity. It can reduce complications of glaucoma filtrating surgery, reduce the probability of trauma, improve vision, and improve quality of life. Key words: cataracts; glaucoma; surgery
