Purpose : To assess the effectiveness of pterygium surgery with mitomycin C in a hispanoamerican population in the state of Oaxaca, Mexico

Methods : This is a retrospective study of 120 eyes of 105 patients that were operated between January 2014 and June 2015. The youngest patient was 20 years of age and the oldest patient was 84. All patients were operated with local infiltration of lidocaine 1%. The method used was bare sclera with application of mitomycin C, a method used at our center since 2004 with no incidence of significant complications. Mitomycin C was applied at a concentration of 0.5mg/ml and a duration of 3 minutes. This was followed by application of dexamethasone drops and tobramycin/dexamethasone ointment. The total duration of the procedure was 15 minutes. Following surgery the eye was patched for a duration of 1 week with qid application of tobramycin/dexamethasone ointment and follow up at 1 day, 1 week, 2 weeks, 1 month, 6 months and then every 6 months.

Results : Of the 120 cases performed, there was one complication of granuloma that resolved and two recurrences. In this group, as in our previous experience, recurrences were they to occur, happened in the early months following surgery. Both best corrected and uncorrected visual acuity improved in all patients. Satisfaction with both functional and cosmetic results was 100%

Conclusions : Bare sclera pterygium surgery with mitomycin C application is a safe, effective and efficient procedure in a hispanoamerican population of Eastern Mexico, yielding a 100% satisfaction rate and a minimal rate of recurrence.
