PURPOSE: To investigate the safety and efficacy of intraoperative application of 5-fluorouracil as an adjuvant in primary pterygium surgery and to evaluate the effect of postoperative subconjunctival 5-fluorouracil injections on the recurrent pterygium.
METHODS: Of 25 consecutive white patients, 28 eyes with primary pterygium underwent pterygium excision with intraoperative application of 5-fluorouracil (25 mg/mL for 3 minutes). The superior and inferior conjunctiva was approximated to cover the scleral bed within 1 mm of the limbus. Recurrence of pterygium was defined as postoperative fibrovascular growth more than 1 mm onto the cornea. Eyes with recurrence less than 2 mm were treated with subconjunctival 5-fluorouracil injections.
RESULTS: After a mean follow-up of 14.1 +/- 3.9 months (mean +/- standard deviation), 7 recurrences (25%) were observed. All recurrences were detected within 12 months. In 4 of 7 recurrences, the fibrovascular growths were less than 2 mm. We, therefore, performed subconjunctival 5-fluorouracil injections. In 3 (75%) of 4 recurrences, the fibrovascular growths became atrophic. No serious complications were observed during and after the surgery. However, superficial punctate keratitis, pain, and hyperemia were detected in all patients in the early postoperative period. As a result, of 28 eyes, 4 (14%) had unacceptable cosmetic results and growing recurrences.
CONCLUSIONS: This study suggests that intraoperative applications of 5-fluorouracil is both efficient and safe in the treatment of primary pterygium. Additionally, postoperative subconjunctival 5-fluorouracil injections may prevent the progression of fibrovascular tissue.
