Abstract

Purpose. To compare the effect of a 3- and 5-minute intraoperative application of topical mitomycin C 0.02% on the recurrence of pterygium. Methods. A comparative, prospective clinical design was used. The study population consisted of 134 consecutive patients with unilateral primary advanced pterygium (growth of 3 mm of more horizontally from the limbus). All underwent excision of the lesion, leaving the sclera bare. At completion of surgery, topical mitomycin C 0.02% was applied for 3 minutes in the first 60 patients (group A) and for 5 minutes in the remaining 74 patients (group B). The patients were followed for 26 months by slit-lamp biomicroscopic examination of the anterior segment. Recurrent pterygium was defined as the postoperative appearance of a fibrovascular tissue crossing the limbus. Results. After 12 months of follow-up, pterygium recurred in 20 patients (33.3%) in group A and in two patients (2.7%) in group B. After 15 months, the recurrence rates were 36.6% and 5.4%, respectively, and remained unchanged at 26 months. There were no cases of drug toxicity in either group. Conclusions. Five-minute intraoperative application of a single dose of 0.02% mitomycin C is safe and more effective than a 3-minute application in recurrence of pterygium.
