Purpose: To evaluate and compare long-term outcomes of trabeculectomies with subconjunctival injections of 5-fluorouracil (5-FU) after sugery or use of mitomycin C (MMC) during surgery. Methods: Retrospective study of 133 eyes who underwent primary trabeculectomy. Results: Intraocular pressure levels were not statistically significant at any of the postoperative visits when comparing the 5-fluorouracil and mitomycin C groups. In each group, analyzed separately, the intra-ocular pressure levels showed no statistically significant difference before or after surgery. The incidence of postoperative complications was not statistically significant as well, except for a greater incidence of the corneal epithelial defects, more frequent in the 5-fluorouracil group. In both groups, a greater incidence of development/progression of cataract was noted. Conclusion: Both mitomycin C and 5-fluorouracil promoted an important and stable decrease in intraocular pressure with similar complication rates.
