Abstract

To compare the long-term efficacy and safety of intraoperative 5-fluorouracil (5-FU) versus mitomycin-C (MMC) used adjunctively with primary trabeculectomy in a Black West African population.Retrospective comparative study supplemented with cross-sectional follow-up data.Review of 68 eyes of 68 Black West African subjects that underwent primary trabeculectomy with the use of intraoperative 5-FU or MMC between January 1, 1988 and January 1, 2002 and had at least 3 years postoperative follow-up. Postoperative outcome measures included intraocular pressure (IOP) control, number of glaucoma medications, visual acuity, and complications.Thirty-eight of sixty-eight eyes received 5-FU and 30 received MMC. Mean postoperative follow-up was 7.5 and 6.5 years in the 5-FU and MMC groups, respectively (P=0.17). A higher proportion of eyes in the MMC group achieved "qualified" (with or without medical therapy) success with varying IOP targets relative to the 5-FU group, but the differences were not statistically significant. "Complete" (without medical therapy) postoperative success was greater in the MMC group with a significantly higher proportion achieving an IOP <21 mm Hg (P=0.02). MMC use was also associated with a lower likelihood of receiving IOP-lowering medications postoperatively (P=0.01). Baseline demographic characteristics, preoperative and postoperative IOP, visual acuity, and complications did not differ significantly between the 2 groups.Intraoperative MMC use is associated with a lower likelihood of requiring postoperative medications and a greater likelihood of achieving IOP lowering without medications relative to the use of 5-FU in a Black West African population.
