Capsular bursa distension síndrome: from diagnosis to treatment

Abstract

Capsular bag distension syndrome is a rare complication of cataract surgery. The main objective was to expose the main ophthalmological findings of this disease and the different diagnostic and treatment alternatives to deal with this infrequent and late complication of cataract surgery. It consists of adhesion of the capsulorhexis rim to the intraocular lens, placed in a capsular bag. Such apposition makes it difficult for fluid to flow through the anterior capsule opening and accumulate in the capsular sac. We present a 71-year-old male patient with a history of cataract surgery by phacoemulsification in the right eye who 11 months ago reported decreased vision in the same eye. The ophthalmologic examination of the right eye showed an uncorrected visual acuity of 0.3 by Snellen chart, which improved to 1.0 with a correction of -1.00 D diopter. Slit lamp examination ruled out any type of anterior segment inflammation. His intraocular pressure was 18 mmHg. She showed a shallow anterior chamber, with an anterior displacement of the iris and a distended capsular sac. The posterior capsule was separated from the posterior surface of the IOL with clear fluid content. Capsular bag distension syndrome was diagnosed. He underwent posterior capsulotomy with Nd: YAG laser. On further evaluation, the patient had uncorrected visual acuities of 1.0 by Snellen chart in both eyes. Capsular bag distension syndrome is a late and infrequent complication of cataract surgery with multiple risk factors, but with rapid resolution.
