Familial corneal degeneration or dystrophy was first described by Groenouw1 in 1890 as the "nodular type of corneal opacities." Forty-three years later, in Breslau, Germany, at the joint annual meeting of the Elschnig and Bielschowsky clinics, I had the pleasure of appearing on the same program with Groenouw, who read a paper entitled "Nodular Type of Corneal Dystrophy Observed for Forty Years." At that time he stated that he was the only one who had personally examined all four generations in the same family.

Lattice-like dystrophy was first described by Haab2 in 1898. An almost similar condition was described by Casper3 as "lattice corneal opacity following injury," but Haab first stated that it was independent of ocular trauma. Fleischer4 grouped together the nodular and lattice types as forms of familial corneal degeneration which appear varied although they have many characteristics in common.
