Map-Dot-Fingerprint Dystrophy is the most common age-related problem associated with the cornea of the eye. The cornea is the clear front part of the eye that we look through. Think of it as the “windshield of the eye”. In this condition, the cornea, which is usually clear and transparent, has microscopic dots and fingerprint-like deposits and areas that appear “map-like” under magnification. Mostly seen in those over 40 this is also called Cogan’s Dystrophy or Anterior Basement Membrane dystrophy. The latter name refers to the layer of the cornea that it affects. This membrane lies in the front portion of the cornea and acts as a barrier behind the softer clear layer coating of the cornea. This membrane becomes uneven and dimpled in Cogan’s dystrophy and causes its unusual appearance.
Many times, this eye problem has no symptoms. Other times, eye discomfort, eye pain upon awakening and irritation of the eye are common symptoms. Corneal erosions are the most problematic outcome as the sensitive front part of the cornea erodes. Eye lubricant medicines and some surgical treatments are sometimes necessary.
