Hypotony and choroidal detachment as a complication of topical combined timolol and dorzolamide
Sharma T; Salmon JFJournal of Ocular Pharmacology and Therapeutics 2007; 23: 202-205
PURPOSE: Hypotony with choroidal detachment is a rare complication of glaucoma medication. In this study, we report on a case which supports the hypothesis that has been proposed to explain this phenomenon. DESIGN: This study was designed as an observational case report. CASE REPORT: A woman with chronic glaucoma underwent trabeculectomy on both eyes. Low intraocular pressure (IOP) developed in 1 eye only, with no visual change for many years. After cataract surgery, the IOP increased, necessitating treatment with topical timolol 0.5% and dorzolamide 2%. She developed monocular hypotony and choroidal detachment 3 months later. This complication occurred in the eye that had previously had a low IOP and resolved completely when topical medication was stopped. The choroidal detachment recurred when rechallenged with the same medication. CONCLUSIONS: Topical aqueous suppression therapy can result in hypotony and choroidal detachment in an eye in which relatively low IOP has been maintained for many years after glaucoma filtration surgery. The problem resolves on stopping the medication.
