Postoperative 5-fluorouracil versus intraoperative mitomycin C in high-risk glaucoma filtering surgery: extended...

To compare the long-term efficacy and safety of postoperative subconjunctival 5-fluorouracil (5-FU) injections with that of intraoperative mitomycin C (MMC) in eyes at high risk for failure of trabeculectomy.

In a retrospective, non-randomized comparative trial, 36 eyes of 36 consecutive patients at high risk for failure of trabeculectomy underwent glaucoma filtering surgery with either postoperative subconjunctival 5-FU injections (19 eyes) or intraoperative application of MMC (17 eyes). Intraocular pressure, number of postoperative antiglaucoma medications, postoperative visual acuity, interventions, and complications were evaluated.

Overall success (intraocular pressure 0.05) between the groups.

These results suggest that both postoperative 5-FU injections and intraoperative MMC application have long-term success in high-risk patients. However, MMC results in a greater decrease in intraocular pressure than 5-FU.
