Electron-microscopical examinations were made of the conjunctiva and cornea of ocular argyrosis. The minute silver deposits were located intracellularly in the connective tissue of the conjunctiva and extracellularly in Descemet membrane of the cornea. The level of distribution of the silver grains in Descemet membrane suggests the time of onset and duration of exposure to silver salts.
