title: [Vogt's crocodile shagreen dystrophy or Valerio's mosaic degeneration. Histological and ultrastructural study].
abstract: A description of a case of Vogt-Valerio corneal dystrophy of spontaneous evolution. The authors studied the histology and ultrastructure of the anterior layers of the cornea removed during keratoplasty. They analysed the lesions found at the level of the epithelium especially the calcific impregnation of Bowman's membrane and the anterior stoma. They suggest that there is localised calcification layed down during the primitive development of the connective tissue in Bowmann's membrane and of the connective tissue of the anterior cornea.
