PURPOSE: To evaluate the characteristics of filtering blebs after fornix-based trabeculectomy with a scleral tunnel. PATIENTS AND METHODS: We studied 119 eyes of 149 patients who had undergone fornix-based trabeculectomy with mitomycin C as their primary surgery between 2000 and 2002 and in whom we could evaluate the characteristics of filtering blebs after a follow-up period of 6 months or more, and whose intraocular pressure at the evaluation time was 18 mmHg or less. We evaluated the width, depth, height, border, avascular area, conjunctival thickness, and late-onset bleb leak of the filtering blebs. RESULTS: The mean period of evaluation was 528 ± 243 days (mean ± standard deviation) after surgery, and the mean intraocular pressure at that time was 12.0 ± 3.0 mmHg. Among these patients, 108 eyes (72.5%) had completely diffuse blebs and 90 eyes (60.4%) had completely vascular blebs. There was no apparent late-onset bleb leak. CONCLUSION: Fornix-based trabeculectomy with a scleral tunnel appears to be an effective method of developing diffuse, vascular and safe blebs with a low risk of late-onset bleb leak. LA: Japanese
