Pterygium excision with conjunctival autograft

Contributors: Mark A. Greiner, MD and Jesse M. Vislisel, MD

Pterygia are wing-shaped folds of conjunctiva and fibrovascular tissue that invade the superficial corneal layers. When extensive, they can result in corneal astigmatism or occlusion of the visual axis. Here, a visually-significant pterygium is removed and a conjunctival autograft is placed in the area of resection to reduce the risk of recurrence. The surgery is sutureless, using fibrin adhesive to secure the conjunctiva.
