This 23-year-old female patient has granular type II (Avellino) corneal dystrophy and recurrent erosions. She has a strong family history of this autosomal dominant corneal dystrophy.  In both eyes, there are linear lattice deposits and granular deposits in the central and paracentral anterior stroma with clear intervening stroma between the deposits. The right eye (top) has undergone phototherapeutic keratectomy and exhibits diffuse subepithelial haze. Treatment for her recurrent erosions included ocular surface lubrication with preservative-free artificial tears, sodium chloride 5% ointment, and rigid gas-permable contact lenses.

47-year-old man with type II granular corneal dystrophy (Avellino) manifested after undergoing LASIK vision correction. Avellino dystrophy is known to blossom after LASIK. For this reason, it is the practice in some Asian countries with high prevalence of Avellino (most prominently Korea where prevalence approaches 1/1000) to perform routine genetic testing to rule out the TGF beta 1 mutation in all candidates for laser vision correction.
