Severe granular dystrophy: a pedigree with presumed homozygotes.

Three siblings with severe granular corneal dystrophy are described. They are most likely to be homozygous for the dominantly inherited gene. They are offspring of a consanguineous marriage, with both parents affected with corneal dystrophies. The case reports describe the severe course of this condition, requiring multiple grafting procedures. Clinical pictures of the family are shown.
