PURPOSE: To evaluate the efficacy of transconjunctival revision (TCR) with mitomycin-C (MMC) following failed trabeculectomy. MATERIALS AND METHODS: The medical records of 27 patients (27 eyes) who underwent TCR with subconjunctival injection of MMC by a single surgeon between September 2001 and August 2013 were retrospectively reviewed. The same surgical protocol was followed for all patients. Revision was performed using a microvitreoretinal blade through a small conjunctival incision. Main outcome measures included visual acuity, intraocular pressure (IOP), and number of glaucoma medications. Failure was defined as an IOP<5 or >14 mm Hg, loss of light perception, or need for additional glaucoma surgery. RESULTS: Mean interval between trabeculectomy and TCR was 56.4±57.2 months. Mean preoperative IOP was 21.9±6.8 mm Hg using 4.0±1.2 glaucoma medications. Fifteen (55.6%) patients met success criteria. At most recent follow-up, mean IOP and number of glaucoma medications for successful patients were 9.7±3.8 mm Hg and 0.6±1.1, respectively. Kaplan-Meier analysis revealed 1-, 2-, and 3-year success rates of 62%, 58%, and 53%, respectively. Three additional patients achieved success after undergoing a second TCR, and 1 patient achieved success after a third TCR. Postoperative complications included transient choroidal effusion (n=8), shallow anterior chamber requiring reformation (n=5), 5-fluorouracil-related corneal epitheliopathy (n=10), and bleb leak (n=1). CONCLUSIONS: TCR with adjunctive MMC is a safe and effective procedure following failure of a trabeculectomy. More than 1 revision may be necessary to achieve long-term IOP reduction.
