Treatment of pterygium with conjunctival limbal autograft and mitomycin C--a comparative study

A total of 60 eyes with primary progressive pterygium were selected. They were randomly divided into two groups ie, group A and group B each consisting of 30 eyes. Group A patients were treated with pteryglum excision with ipsilateral conjunctival-limbal autografting. Group B patients were treated with pterygium excision followed by mitomycin C 0.02% for two minutes. Both groups were followed up for one year postoperatively to document recurrence rates and postoperative complications. In group A recurrence rate was 3.0% with minimal ocular complication after one year follow-up. But in group B recurrence rate was high as 10.0% and ocular complications were significant after the same period of postoperative follow-up. Both conjunctival-limbal autograft and intra-operative mitomycin use are effective method of surgical treatment of pterygium but considering the rate of recurrence and other postoperative ocular morbidity conjunctival-limbal autografting seems to be the best method of pterygium treatment.
