Aim: to evaluate the safety and the efficacy of subconjunctival injection of bevacizumab (Avastin) for the management of primary pterygium and to estimate the recurrent rate of pterygium after surgery Methods: In this randomized prospective clinical study, the patients were randomized into two groups of 30 patients each. Study group received 1.25 mg/0.05 ml subconjunctival bevacizumab 1 week before pterygium surgery with conjunctivalautograft. Control group received 1.25 mg (0.05 ml) subconjunctival normal saline 1 week prior to pterygium surgery with conjunctivalautograft. Patients were followed up at day 1, day 7, 1 month and 3 months. The main outcome measures were morphology of pterygium after injection, intra operative ease, recurrence of pterygia, and any complications. Results: After giving bevacizumab, there was statistically significant improvement in grade, color intensity, size of pterygium, and symptoms of patients. Intra operatively, less bleeding was observed by the surgeon. No statistically significant difference regarding reduction in astigmatism, improvement of visual acuity, and complications were observed in two groups. Recurrence was noted in five patients (8.33%) in total study population at the end of 3 months. It was present in two patients (6.67%) in Group A and three patients (10%) in Group B. Conclusion: Single preoperative administration of subconjunctival injection bevacizumab given 1 week before the pterygiumexcision with conjunctivalautograft decreases the vascularity of newly formed blood vessels, hence decrease recurrence rate of pterygium .
