AIM: To investigate the effect of trabeculectomy with and without mitomycin C in post-keratoplasty glaucoma. METHODS: A retrospective study was performed on patients who underwent trabeculectomy for glaucoma after penetrating keratoplasty. Thirty-four eyes of 32 patients were included in this study; 26 eyes received trabeculectomy with mitomycin C and eight eyes without mitomycin C. The procedure was deemed successful if the intraocular pressure was maintained below 21 mmHg with or without use of additional antiglaucoma medication (mean follow-up time 22.3 (SD 10.3) months). RESULTS: At the last examination trabeculectomy was successful in 19 of 26 eyes (73.0%) with mitomycin C (+) and two of eight (25.0%) without (p = 0.0219). When the prognosis was analyzed by Kaplan-Meier curve, the mitomycin C (+) group showed a better prognosis (p = 0.0182). Mean intraocular pressure and average number of glaucoma medications improved in the group with mitomycin C without severe side-effects on the graft. Graft rejection after trabeculectomy was seen in two eyes in the mitomycin C group. Final graft clarity rate was 69.2% (18/26) in the mitomycin C (+) group and 37.5% (3/8) in the mitomycin C (-) group. Complications such as persistent epithelial defect, cystoid macular edema, choroidal detachment, leakage from bleb were seen in four eyes in the mitomycin C (+) group and in one eye in the mitomycin C (-) group. CONCLUSIONS: Trabeculectomy with mitomycin C showed better results for glaucoma following keratoplasty.
