A 57-year-old black man had François-Neetens speckled dystrophy of the cornea and orbital phycomycosis. Examination of family members confirmed an autosomal-dominant pattern of inheritance. Light and electron microscopic study of the cornea of a blind eye disclosed that the corneal opacities were represented by swollen, vacuolated keratocytes filled with histochemically demonstrable acid mucopolysaccharide and complex lipids. Thus, this dystrophy may represent a dominantly inherited metabolic disorder confined to the cornea.
