[Etiology and pathogenesis of recurrent erosions of the cornea. A scanning and transmission electron microscopy study].

Scratched off corneae of 2 patients were examined under the scanning electron and the transmission electron microscope. Whereas in the scanning electron microscope the expected picture of the destruction of the epithelium in the upper zones of the cornea could be presented in the 1st case, the histological picture of the 2nd case shows in the transmission electron microscope the reaction of the influence of the noxa to the texture of the epithelial cells, to the protoplasm, and to the nucleus of the concerned epithelial cell.
