Hypotony Maculopathy Following Trabeculectomy With Mitomycin C

Abstract

Although hypotony occurs frequently after glaucoma filtration surgery, decreased visual acuity due to macular changes is rare. We report a case of hypotony maculopathy with marked decrease in visual acuity following an otherwise uncomplicated trabeculectomy using intraoperative mitomycin C. Report of a Case. —A 29-year-old white man with myopia and a history of bilateral penetrating keratoplasties 10 years previously for congenital hereditary endothelial dystrophy was referred with elevated in traocular pressure despite receiving maximum tolerated medical therapy. Best corrected visual acuity was 20/300 OD with a -11.00+2.00×130 and 20/60 OS with a -14.00+4.75×161. Intraocular pressure ranged from 32 to 44 mm Hg OU. Slit-lamp examination revealed clear corneal grafts in both eyes, deep anterior chambers in botheyes, normal irides, and clear crystalline lenses. The angles were wide open and without peripheral anterior synechiae. Funduscopic examination disclosed a tilted disc with an inferior notch in the right eye and a tilted
