Background. To compare the efficacy of needle revision with 5-fluorouracil (5-FU) and mitomycin C (MMC) on dysfunctional filtration blebs shortly after trabeculectomy. Methods. It is a prospective randomized study comparing needle revision augmented with MMC or 5-FU for failed trabeculectomy blebs. Results. To date 71 patients (75 eyes) have been enrolled, 40 eyes in the MMC group and 35 in the 5-FU group. 68 patients (72 eyes) have completed 12-month follow-up, 38 eyes in the MMC group and 34 in the 5-FU group. The mean IOP before and that after needle revision in the MMC group were  mmHg and .4 mmHg, respectively (), and in the 5-FU group were  mmHg and  mmHg, respectively (). At 12-month follow-up, complete success rates were 57.5% for MMC group and 34.3% for 5-FU group (; log-rank test) and 75% and 60% (; log-rank test), respectively, for the qualified success. Complication rates between the two groups were not statistically different (). Conclusions. Needle revision and subconjunctival MMC injection were more effective than needling and subconjunctival 5-FU injection for early dysfunctional filtration blebs after trabeculectomies.
