Injury to the Optico-chiasmal Junction-a Case Report.

LE COUILLARD.-Ionisation dans les sclerites (These de Paris, 1933). LEDUc.-Introduction des substances medicamenteuses dans la profondeur-des tissue par le courantelectrique, A nn. THIS ihteresting case of injury to the visual pathway presented a difficult problem' in localisation and in pathology. I can find no case quite comparable to it in the literature, and it has the added advantage that the lesion has been inspected at operation. Major H. W. B., aged 31 years, sustained'a severe head injury as the, result of a head-on-motor crash, the site of the injury was the left frontal region, and he had a fissured fracture running down in the left frontal bone, traversing the left frontal sinus, running-along the floQr of the left anterior fossa lateral to the optic canal, and then passing down into the left middle fossa. The actual course of this fracture has been. verified' in the course of two operative procedures. No definite fracture into the left Qptic canal was located, either by X-Ray or by direct vision; X-Ray; however, five months after injury showed this canal to be a little irregular in ou'tline and larger than its fellow. No-fracture of the left anterior clinoid process was demonstrable by X-Ray, or seen at operation.
