Abstract
Purpose: :
The purpose of this study was to compare the outcome of Mitomycin C (MMC) augmented trabeculectomy in glaucoma patients with uveitis to those without uveitis but with other high risk characteristics.
Methods: :
Fifty–one eyes of 51 patients (21 uveitic patients and 30 non–uveitic patients) were included in the study. Two outcome classifications were analyzed: absolute success (IOP < 30% baseline without glaucoma medications or 5–Fluorouracil (5–FU) injections), and qualified success (IOP < 30% baseline with glaucoma medications or 5–FU injections). Kaplan–Meier survival curves were constructed for both models.
Results: :
After a mean follow up of 52 months, uveitis emerged as a negative predictor of success. In the qualified success model, uveitic patients demonstrated survival rates of 90% and 79% at 1 and 2 years compared to 100% for all time points in the control group (wilcoxon test, p=0.005). Uveitic patients were more likely to require postoperative 5–FU injections than the control group (33% vs. 10%, respectively, p=0.039) and were more likely to require glaucoma medications postoperatively for IOP control (38% vs. 3%, respectively, p=0.001).
Conclusions: :
Uveitic glaucoma patients are more likely to require post–operative therapeutic interventions to maintain adequate pressure control in the short–term and are at higher risk of surgical failure in the long–term.
