Corneal Dystrophy, Epithelial Basement Membrane
Type of disease: Rare conditions
Epithelial basement membrane corneal dystrophy is a condition where the epithelium of the cornea (the outermost region of the cornea) loses its normal clarity due to a buildup of cloudy material. It gets its name from the unusual appearance of the cornea during an eye exam. This dystrophy occurs when the epithelium’s basement membrane develops abnormally, causing the epithelial cells to not properly adhere to it. This leads to recurrent epithelial erosions, which can cause blurred vision and severe pain. This condition is usually not inherited. However, families with autosomal dominant inheritance and mutations in the TGFBI gene have been identified.
