Hypotony and choroidal detachment as late complications of trabeculectomy

Abstract

Seven eyes of six patients with glaucoma developed a flat anterior chamber, hypotony, and choroidal detachment two to 26 months after technically uncomplicated trabeculectomy. No signs warranting immediate surgical intervention, such as wound or bleb leakage, contact between cornea and lens, or massive choroidal detachments touching in the midvitreous cavity were found on initial examination. After treatment with topical corticosteroids and cycloplegic eyedrops, five of seven eyes showed marked clinical improvement within one month. The two remaining eyes eventually returned to normal anterior chamber depth, but required repeat filtration surgery for intraocular pressure control.
