Recurrent Granular Dystrophy of the Cornea

Abstract

A severe course of corneal granular dystrophy can be present in the absence of evidence of a homozygous mutational status, or a novel mutation. Molecular genetic analysis revealed a new polymorphism in this patient. The histopathologic findings support the assumption of an epithelial origin of the granular corneal deposits. Phototherapeutic keratectomy and penetrating keratoplasty may improve vision, but cannot prevent recurrence of the disease.
