Role of Sub-Conjunctival Bevacizumab in Post Pterygium Excision Management

Summary

A pterygium is a fibrovascular growth originating from the conjunctiva that grows onto the surface of the cornea. Frequently, these pterygia will recur even after surgical resection. Bevacizumab is an inhibitor of angiogenesis, which is needed for recurrent growth. The use of bevacizumab is poorly understood in inhibiting pterygium growth. The objective of this study is to compare the effects of wound healing and recurrence rates in postoperative bevacizumab versus pterygium excision alone.
