Brief 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.

Condition or disease Intervention/treatment Phase
Pterygium Drug: Bevacizumab Phase 4

Detailed Description:
This is a prospective trial. Thirty-one patients with a primary pterygium of at least 2 mm in size and without any previous ocular surgery will be included. Outcome measures will include best corrected visual acuity, intraocular pressure, recurrence, and any sight threatening complications at two weeks, two months, and six months postoperatively.

Arm Intervention/treatment
Placebo Comparator: Pterygium Excision Alone
Experimental: Pterygium Excision with Bevacizumab Injection Drug: Bevacizumab

Primary Outcome Measures :
  1. number of recurrent pterygia with postoperative bevacizumab [ Time Frame: 6 months ]
    The number of recurrent pterygia with patients who received bevacizumab after pterygium excision was compared to the number of recurrences in those patients who only had pterygium excision.
