 Pterygium is a noncancerous growth of the conjunctival tissue over the cornea. It is a progressive disease that may lead to visual impairment in advanced stages, as well as restriction of ocular motility, chronic inflammation and cosmetic concerns. Surgical removal is the treatment of choice, but recurrence of pterygium is a frequent problem. In this randomized controlled cauterization will be compared with fibrin glue for conjunctival autografting in primary pterygium surgery.
