Pterygium is a common ocular surface disorder characterized by chronic proliferative conjunctival fibrovascular tissue growth over the cornea.1 Numerous pterygium excision techniques have been tried with a wide range of recurrence rates, including bare sclera excision (30%–70%),2 amniotic membrane (6.4%–42.3%), and conjunctival autograft with or without glue (0%−16.7%).3,4 A recent Cochrane study found a 47% reduced risk of recurrence with conjunctival autograft at 6 months compared with amniotic membrane for pterygium excision.
