Purpose: To correlate the morphologic appearance of filtering blebs in the early postoperative period with the outcome of trabeculectomy with mitomycin C (MMC) during the first postoperative year. Patients and Methods: In a prospective study, the morphologic appearance of filtering blebs after primary trabeculectomy with adjunctive MMC (0.1 mg/ml for 5 minutes intra-operatively) was classified; 49 eyes of 49 patients were examined preoperatively, I and 3 days, I and 2 weeks, 1, 3, 6, and 12 months postoperatively. Status of filtering bleb, intraocular pressure (IOP), and number of medications were recorded. Results: One year after surgery all patients had IOP less than or equal to 21; 6 patients received antiglaucoma medication. One eye required needling of the filtering bleb because of encapsulation. During the first postoperative year, eyes with conjunctival subepithelial micro cysts, observed in the first and the second postoperative week, had significantly lower mean IOP, than eyes without (11.1 mm Hg vs. 13.9 mm Hg; p:0.0043, ANOVA). Eyes with corkscrew vessels, observed in the first and the second postoperative week, had significantly higher mean IOP, than eyes without during the first postoperative year (13.4 mm Hg vs. 11.7 mm Hg; p:0.0141, ANOVA). Conclusion: Classification of filtering blebs after trabeculectomy with MMC may help to disclose patients with an increased failure risk.
