CHARACTERISTIC - DISTRIBUTION OF DEPOSITS IN RECURRENT GRANULAR CORNEAL-DYSTROPHY

Granular corneal dystrophy can recur after penetrating keratoplasty. I n those cases as in the early primary manifestation of the disease, de posits are found predominantly in the superficial corneal layers, Ar a later stage, stromal deposits can also be seen. We describe an additi onal particular location of deposits and correlate clinical with histo logical findings in three corneas from two patients. Deposits were fou nd mainly superficially within the graft and around the edge of the tr ansplant along the scar between host and donor cornea. We suggest that the deposits are of epithelial origin, though their production by str omal cells cannot be excluded. Chemical interactions are discussed as an explanation for the characteristic distribution of the deposits.
