Trabeculectomy with antiproliferative agents in uveitic glaucoma.

Abstract

To evaluate the outcome of trabeculectomy with antiproliferative agents in patients with uveitic glaucoma A retrospective chart review of 44 eyes of 44 patients with uveitic glaucoma who underwent trabeculectomy with mitomycin C or 5-fluorouracil. The authors defined complete success as an intraocular pressure of 21 mm Hg or lower without pressure-lowering medications, qualified success as an intraocular pressure of 21 mm Hg or lower with medications, and failure as an intraocular pressure of more than 21 mm Hg with medications, loss of light perception, or the need for reoperation. The cumulative probability of complete or qualified success was 78% at 1 year and 62% at 2 years. At 2 years, success rates were 39% in males and 71% in females (P = 0.02), 74% in white patients and 55% in black patients (P = 0.58), and 45% in patients with idiopathic uveitis and 74% in patients with sarcoid uveitis (P = 0.17). Sixteen of 31 (51.6%) phakic patients developed new cataracts or had progression of existing cataracts and required cataract extraction. Four of 16 eyes (25%) lost intraocular pressure control and needed repeat trabeculectomy after undergoing cataract surgery. Patients with uveitic glaucoma can have good outcomes after trabeculectomy with antiproliferative agents. Male gender was the only statistically significant risk factor for trabeculectomy failure. Cataract management in the presence of a filtering bleb poses a treatment dilemma between improvement of visual acuity and loss of intraocular pressure control.
