PURPOSE: To evaluate the efficacy of cyclodialysis-enhanced Mitomycin c (MMC) trabeculectomy in post-keratoplasty glaucoma. DESIGN: Prospective, non-comparative, interventional case series. METHODS: A total of 45 eyes of 45 consecutive patients with refractory glaucoma after penetrating glaucoma underwent a cyclodialysis-augmented trabeculectomy with MMC. The visual acuity, intraocular pressure (IOP), corneal clarity, and graft failure were evaluated over a minimum follow-up of 2 years. RESULTS: The mean age of the patients was 55.4+/-9.4 years. The cyclodialysis-augmented MMC trabeculectomy procedure resulted in a mean reduction of IOP from 38.9+/-3.9 mmHg (95% confidence interval (CI) 35.9-42.2) at baseline to 11.3+/-2.8 mmHg (95% CI 9.5-12.9), at final follow up (P=0.002). Blebs were avascular, diffuse, and extended posteriorly. Postoperative UBMs revealed the presence of a cyclodialysis with a small associated suprachoroidal effusion and a subconjunctival filtering bleb in all cases. CONCLUSIONS: Cyclodialysis-augmented MMC trabeculectomy provides a safe and effective method of lowering IOP in intractable glaucoma following penetrating keratoplasty, without compromising the corneal graft survival and clarity.
