TRAUMATIC LESIONS OF THE OPTIC CHIASMA: A REPORT OF FOUR CASES
Canadian Medical Association Journal
|January 18, 1964
Abstract:
Case histories of four patients who suffered severe head trauma resulting in complete bitemporal hemianopia are presented. The optic chiasm was visualized in only one patient. It was markedly swollen and disintegrated. This appearance was consistent with multiple minute tears of the crossed fibres in the median sagittal plane. Other theories to explain the bitemporal field defect are discussed.
