Granular corneal dystrophy Groenouw type I. A report of a probable homozygous patient.

A case of severe granular corneal dystrophy is described. The patient, who is most probably homozygous for the dominantly inherited dystrophy gene, is the product of a first cousin marriage with both parents mildly affected by the same dystrophy. The case report describes an early onset and a severe course with two grafts in each eye before the age of 17. Pictures of the clinical appearance, histology and transmission electronmicroscopy are shown.
