Comparison of Recurrence Rate of Pterygium between the Patients Managed With Auto Graft and Bare-Sclera

Introduction: Pterygium appears as a fleshy vascular mass that occurs in the inter palpebral fissure. The typical pterygium is triangular in shape and is made up of a cap, head and body. It is more frequently located nasally rather than temporally.The cause of pterygium is not known but those who work outside in the sun and wind are more prone to develop pterygium probably from conjunctival irritationand is more common in tropical & subtropical region with a reported prevalence of 2 to 7 % worldwide. Objectives: To compare the frequency of recurrence of pterygium between the patients managed with auto graft and Bare-sclera Study design: Randomized Controlled Trial. Settings: The study was conducted at Department of Ophthalmology, Bahawal Victoria Hospital, Bahawalpur. Duration of study: From March 2017 to September 2017 over the period of 6 months Results: Total 92 patients were selected for this study. Mean age of the patients was 40.12 ± 13.843 years, mean age of group A was 39.63 ± 13.468 years and mean age of group B was 40.61 ± 14.339 years. Out of 46 patients of group A, recurrence of pterygium was noted in 7 (15.22%) patients. In group B, recurrence of pterygium was noted in 17 (36.96%) patients. Significantly higher difference of recurrence of pterygium between the both groups was noted with p value 0.0314. Conclusion: In this study higher rate of recurrence of pterygium was noted in Bare-sclera group as compared to auto graft group
