Map-dot-fingerprint corneal dystrophy

Map-dot-fingerprint dystrophy is an abnormality of the cornea (the clear front surface of the eyeball) in which the cells that cover the surface of the cornea do not retain the normal glassy smoothness of a healthy cornea. Rather, the cells on the surface become loosened from the underlying tissue and build up irregular elevations in patterns that may resemble maps, dots, fingerprints, or other irregular surfaces. This is a dominant inherited trait in some families. Because the surface cells are loosened from the underlying tissue, the surface of the cornea can break down and create pain. There may be increased susceptibility to infection of the cornea as well. Be sure to maintain regular follow-up with your ophthalmologist.
