A Novel KERA Mutation in a Case of Autosomal Recessive Cornea Plana With Primary Angle-Closure Glaucoma.

Purpose: Keratocan is a cornea-specific keratan sulfate proteoglycan found predominantly in the adult vertebrate eye. In human beings, mutations in keratocan (KERA) are associated with autosomal recessive cornea plana (CNA2), which is characterized by a flattened forward convex curvature of the cornea. Here, we report a novel mutation in a case of autosomal recessive bilateral cornea plana presenting with primary angle-closure glaucoma in a 41-year-old woman from Eastern India.
