Bilateral Congenital Protruding Corneal Leukoma
... Purpose: Congenital corneal leukoma is rare with an incidence of 6/100000 and is one of the most important causes of amblyopia. Here we report an unusual case of bilateral congenital elevated corneal leukoma. Methods: We encountered a 13-day-old full term male newborn. Ocular examination of both eye ...
