Trabeculectomy with intraoperative 5-fluorouracil.

BACKGROUND AND OBJECTIVE

To investigate the outcome and complication rates of trabeculectomy following the combined use of intraoperative, topical 5-fluorouracil (5-FU) and low-dose, postoperative subconjunctival 5-FU injections.

PATIENTS AND METHODS

Forty-one eyes of 41 patients with advanced, medically uncontrolled glaucoma underwent trabeculectomy with intraoperative episcleral application of 5-FU (50 mg/ml for 5 minutes). A variable number of subconjunctival 5-FU injections were administered postoperatively at the discretion of the operating surgeon.

RESULTS

Six-, 12-, and 15-month life-table success rates (5 mm Hg < or = intraocular pressure [IOP < or = 21 mm Hg) were 100%, 97%, and 83%, respectively. Mean postoperative IOP was 12.1 +/- 4.3 mm Hg. An average of 2.2 +/- 1.6 (range 0 to 7) supplemental subconjunctival 5-FU injections were administered postoperatively. Corneal epithelial erosions developed in 7 (17%) of the eyes. Five of 7 patients who underwent subsequent surgical procedures maintained successful control of IOP at an average of 11.0 +/- 4.8 (range 5 to 16) months after the secondary surgery.

CONCLUSION

Trabeculectomy with intraoperative 5-FU is effective in controlling IOP while possibly minimizing the need for frequent postoperative injections and the occurrence of corneal epitheliopathy.
