Corneal dystrophy, microcystic (health)


A disorder in which the cornea (the normally clear front window of the eye) shows dots (or microcysts), geographic map-like lines, and grayish fingerprint lines on examination with a slit-lamp, a device that focuses a high intensity light beam as a slit while the examiner looks at the front of the eye through a magnifying scope. The disorder is usually silent and without symptoms. However, about one patient in ten has recurrent erosion of the cornea that usually begins after the age 30.
