A family has recently been observed of which the members presented hereditary corneal dystrophy, a condition to which attention should be called because of its relative rarity and because of the slight variation which new pedigrees add to existing knowledge of it.
A hereditary type of corneal dystrophy, or "nodular corneal opacities," was first described by Groenouw,1 in 1890. His accurate, lucid and complete observations on 2 patients, not related to each other, left little to be added to the description of this disease. He erred, however, in that he gave a composite picture of the lesions in the 2 cases, for he did not realize that he was dealing with two separate clinical entities. In his composite description, both corneas were affected with numerous sharply defined gray opacities less than 0.25 mm. in diameter. The opacities were closely placed, discrete and separated by healthy corneal stroma. Between
