Status
active

A rare corneal dystrophy characterized by thickened, redundant sheets of basement membrane extending into the corneal epithelium, as well as intraepithelial lacunae filled with cellular debris, together presenting as a pattern of ''maps'', ''dots'', and ''fingerprints'' on slit-lamp examination. Patients may be asymptomatic or present with recurrent episodes of painful corneal erosions with variable visual impairment, typically beginning after the age of thirty. The condition is bilateral and may be inherited in an autosomal dominant manner.
