A clinical study of comparison of pterygium surgery with and without Mitomycin- C on bare sclera technique

Introduction: A pterygium is a triangular wedge of fibro-vascular conjunctival tissue that appears on the epibulbar conjunctiva, which can be removed by various methods. Recurrence of Pterygium after exicision is a very common problem encountered by ophthalmologist. Several methods have been suggested to avoid these recurrences. We studied the recurrence rate of pterygium after application of intraoperative mitomycin C (0.04%). Method: This is a prospective study of fifty eyes in fifty patients who underwent pterygium excision by the same surgeon using intraoperative topical mitomycin C(25 patients) and without using mitomycin c(25 patients) during September 20014—September 2015 in the ophthalmology department at Jhalawar medical college, Jhalawar( raj.). 0.04% Mitomycin applied to bare sclera after excision for two minutes by swab sticks. Postoperative follow up period was 6 months. Outcomes measured in the form of recurrence and complications were analyzed. Results: In Group A with use of mitomycin C there was no recurrence after 6 months follow-up while in Group B recurrence was seen in 5 patients within 3-6 months, however in group A, 1 patient had scleral thinning. Conclusion: Intraoperative administration of mitomycin C 0.04% is safe and effective to prevent pterygium recurrences.
