Corneal granular dystrophy. A light and electron microscopical study of its recurrence in a graft.

Histochemical evidence suggests that the amorphous stromal deposits of corneal granular dystrophy are composed essentially of a non-collagenous protein or polypeptide complex, the precise nature of which, however, is unknown (Seitz and Goslar, I963; Garner, I969). Electron microscopy fortunately enables a further dimension of this material to be studied, and the present report gives the findings in a corneal disc removed from an established case of granular dystrophy during a repeat keratoplasty after the recurrence of the disorder in the original graft.
