Also known as:
The corneal dystrophies comprise a group of inherited, usually progressive disorders affecting the cornea (outer clear layer of the eyeball). They are occasionally present at birth but more frequently appear during the teen years and progress throughout life. Most are transmitted as autosomal dominant disorders with the exception of macular corneal dystrophy which is transmitted as an autosomal recessive. The inborn error of metabolism in the tissues in and around the eye that causes the macular form of the disorder has been identified.
