[Ultrastructure of macular corneal dystrophy (Groenouw II): investigations of paracentral deep corneal layers (author's transl)].

Electron microscopic studies proved, that in cases of macular corneal dystrophy (Groenouw II) abnormal deposits of acid mucopolysaccharide are demonstrable in the different layers of the cornea in a polymorphic form. Because of the investigations now performed it can be established, that the opacities of the paracentral, deep corneal layers result from both dispersed vesicular and plaque-like deposits of storage material in the border area of the stroma and Descemet's membrane.
