Rochon-Duvigneaud (Paris): On the amblyopia occurring in the last stage of cancer. With the exception of a slight anaemia of the optic disc Rochon-Duvigneaud could find no anomalies in the fundus. Nor could he find in the retina, optic nerves, chiasm, or optic central organs, in a case that had been examined in life, anything abnormal. He would explain the amblyopia as being due to an excessive anaemia of the visual centres.
