Superficial juvenile granular dystrophy.

Seventeen cases of a superficial corneal dystrophy are presented. The lesions are subepithelial, limited mainly to Bowman's layer. This dystrophy, although clinically different from classic granular dystrophy, is pathologically similar to it. Treatment, consisting of superficial keratectomy to 15% to 20% of corneal thickness, did not require lamellar grafting and produced good visual results. A new classification of granular dystrophy is proposed.
