PURPOSE: To determine the long-term intraocular pressure (IOP) control and postoperative complications after initial trabeculectomy with use of mitomycin C (MMC) in patients with primary open-angle glaucoma (POAG). PATIENTS AND METHODS: A retrospective review was conducted of a consecutive series of 123 eyes (87 patients) with POAG who underwent initial trabeculectomy with MMC and had at least 4 years of follow-up. All patients underwent standard trabeculectomy with 0.04% MMC applied intraoperatively for 3 minutes. The long-term outcomes (IOP control and bleb leak, long-standing hypotony, bleb-related infections) were analyzed with the Kaplan-Meier life-table method on the basis of three definitions of successful IOP control (defined as IOP <18 mmHg (definition 1), IOP <16 mmHg (definition 2), and IOP decrease of by > or =30% and <21 mmHg (definition 3)). RESULTS: The mean follow-up time was 6.8+/-1.4 (mean+/-SD) years. The cumulative survival rates were 67.0+/-4.6%, 44.5+/-5.4%, and 74.1+/-4.2%, respectively, based on definitions 1, 2, and 3, 8 years postoperatively by life-table analysis. At 8 years, bleb leak occurred in 7.9+/-2.6% of eyes, long-standing hypotony in 8.3+/-2.5%, and bleb-related infections in 5.9+/-2.4%. CONCLUSION: Long-term outcome after initial trabeculectomy with MMC in Japanese POAG patients is comparable with that reported in other populations and with that after trabeculectomy with 5-fluorouracil.
