Clinical analysis on angle-closure glaucoma with binocular asymmetry of anterior chamber depth

Abstract

Objective To analyze clinical features and treatment for angle-closure glaucoma with binocular asymmetry of anterior chamber depth. Methods Twenty-one eyes of 21 cases with binocular asymmetry of anterior chamber depth were analyzed retrospectively (relaxation of ciliary zonule in 2 cases; subluxation of lens in 18 cases; glaucoma secondary to retinal vascular occlusion in 1 case). All cases were characterized by high intraocular pressure, shallow anterior chamber, anterior chamber angle closure, and similar to primary angle closure glaucoma. Ectopia lentis occurred in 20 cases. All cases underwent YAG laser peripheral iridotomy, trabeculectomy or lens extraction, even combined with anterior vitrectomy. The posterior chamber lenses were implanted into the capsular bag or suspended according to the different instances of relaxation of ciliary zonule. Secondary glaucoma was treated with intravitreal injection of Conbercept. Results After operation, all cases obtained normal intraocular pressure and visual acuity increased to 0.12-0.8. Conclusion It is very important to differentiate the patients of glaucoma due to binocular asymmetry of anterior chamber depth from primary angle-closure glaucoma. Good surgical efficacy can be obtained via different types of operations according to different situations of diseases.
