Pterygium is wing-shaped, vascular, fleshy growth that originates on the conjuntiva and that can spread to the corneal limbus and beyond The surgical exeresis with autologous conjunctival autograft technique is the treatment of choice. Commercially available fibrin glue has been used preferentially for graft fixation due to its benefits compared to sutures; However, its cost and the risk of inflammatory immune reaction limit the its use. There are few studies about autologous fibrin glue.

OBJECTIVE: To determine the efficacy of autologous fibrin glue preparation in patients undergoing pterygium resection surgery. To compare with autologous conjunctival graft fixation with suture.

This is a randomized clinical trial. Two patient groups will undergo pterygium excision surgery. Group 1 will have autologous conjunctival graft fixation with autologous fibrin glue and group 2 will have suture graft fixation using 10.0 mononylon. Early and late postoperative surgical results as well as complication rates will be analyzed.
