IT IS UNDERSTANDABLE that reports of traumatic visual field defects should appear during times of world stress. It is intended in this report to show the variety of visual field lesions encountered in the current conflict.
DIFFERENTIAL SIGNS IN LOCALIZATION
—It is well known that the most important single point of differentiation between homonymous hemianopsias due to anterior lesions of the visual pathway (optic tracts and anterior radiations) and those due to posterior lesions (posterior radiations and occipital cortex) is the congruity of the visual field patterns of the two eyes.It appears that visual fibers from corresponding points of the two retinas do not become closely allied until they have passed an appreciable distance beyond the chiasm. This is so despite the fact that corresponding fibers are projected onto identical areas of the visual cortex.Lesions of the optic tracts produce homonymous hemianopsias in which the patterns of
