To assess the outcome of trabeculectomy supplemented with intraoperative 5-Fluorouracil (5 FU) application in glaucoma patients.


A prospective non-randomized case series of 76 eyes of 76 consecutive patients who underwent trabeculectomy with intraoperative sponge 5 FU (25 mg/ml). Minimum follow-up was 6 months. There were 31 eyes in the low-risk group and 45 eyes in the high-risk group. The reduction in intraocular pressure (IOP) and any treatment complications were noted.


The mean preoperative IOP was 28+/-7.72 mm Hg. The mean final postoperative IOP was 16.8+/-6.1 mm Hg. The average number of glaucoma medications required dropped from 1.8+/-0.8 preoperatively to 0.4+/-0.8 after the operation (p<0.001). Cumulative success rates (IOP less than 21 mm Hg) for all eyes were 93% and 81% at 6 and 12 months, respectively. There was no difference in outcome between the low- and high-risk groups if criteria for success were an IOP of less than 21 mm Hg or an IOP of less than 21 mm Hg and an IOP reduction of 30%. However, if success is defined as an IOP of 15 mm Hg or less and a 30% fall in IOP, then the low-risk group had significantly longer survival times than the high-risk group (p=0.033, log-rank test). Transient punctate keratitis and corneal epithelial defect were each observed in only 1 eye. Other serious complications include rapid progression of cataract in 2 eyes, endophthalmitis in 1 eye and hypotonic maculopathy after subsequent cataract extraction in 1 eye.


Single dose intraoperative 5 FU appears to be a safe and useful adjunct to trabeculectomy. IOPs in the low teens were achieved in a greater proportion of low-risk eyes than high-risk eyes.
