Dots, cysts and maps in the cornea of a patient complaining of suggestive recurrent corneal erosions episodes.

Named after the slit lamp appearance of corneal findings, Map-dot-fingerprint Dystrophy is the most common corneal dystrophy. Map-dot-fingerprint dystrophy, Cogan’s dystrophy, Cogan microcystic epithelial dystrophy, epithelial basement membrane dystrophy, and anterior basement membrane dystrophy all designate the same condition.

Frequently clinical cases lack all the characteristics needed for the classical definition of dystrophy. In accordance to the International Committee for Classification of Corneal Diseases (IC3D), map-dot-fingerprint dystrophy could, but for a few cases, be more accurately categorized as a corneal degeneration.
