Schnyder crystalline corneal dystrophy is an autosomal dominant condition caused by a mutation in the UbiA prenyltransferase domain-containing protein 1 (UVIAD1). It results in deposition of cholesterol and phospholipid crystals in the central corneal stroma. Later, the patients develop a dense corneal arcus, and eventually midperipheral corneal opacification and decreased corneal sensation.
