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.
