Three patients with granular corneal dystrophy Groenouw type I underwe
nt corneal grafting, and cryostat sections of the corneal buttons were
examined immunohistochemically for immunoglobulins. Positive results
were obtained for IgG, Kappa-, and Lambda chains with immunofluorescen
ce technique. The reactions were seen exclusively in the same localiza
tions as the Masson trichrome positive deposits.
