Abstract:
PURPOSE:To test the effect of postoperative subconjunctival 5-fluorouracil (5-FU) on the pressure outcome in combined procedure (limbus-based trabeculectomy + clear-cornea phacoemulsification). METHODS:Prospective randomized, controlled clinical trial; n = 24 eyes (24 patients) with concurrent open-angle glaucoma and cataract; 12 eyes per treatment group; sample size adjusted for a minimal expected difference in the event rate between the 2 treatment groups = 50%, control rate = 20%; type I error = 0.05; power = 95%. Uncomplicated limbus-based trabeculectomy + uncomplicated clear-cornea phacoemulsification + posterior chamber intraocular lens. The 5-FU group = five subconjunctival injections of 5 mg 5-FU, starting from day 8 after surgery, one injection per week. Control group = no injections. The groups were matched for age, preoperative intraocular pressure (IOP), duration of preoperative antiglaucoma treatment, preoperative pilocarpine and adrenergics, preoperative laser trabeculoplasty, and beta-blockers in the fellow eye. The IOP less than or equal to 15 mmHg without treatment 1 year after surgery (IOP = average of the two highest values measured in the diurnal curve, 8 AM to 6 PM, one reading every 2 hours). RESULTS:Each patient completed a 1-year follow-up. Ten of 12 eyes of the 5-FU group showed an IOP less than or equal to 15 mmHg at the end of follow-up versus 1 of 12 eyes in the control group (Fisher's exact test, P = 0.00064). The IOP range was 10 to 17 mmHg in the 5-FU group and 14 to 22 mmHg in the control group. CONCLUSION:Postoperative 5-FU may improve the 1-year success rate of trabeculectomy combined with clear-cornea phacoemulsification.
