It is po ible cases of lateral hemianopsia to throw the light the eye so that it falls upon the blind half of the 1 If when this is done the pupil contraets, the indict' tion is that the reflex arc referred to is perfect, by which is meant that the optic nerve-fibers from the retinal expansion to the center, the center itself, and the third nerve are uninvolved. In such a case the conclusion would be justihed that the cause of the hemianopsia was central; that is, situated behind the geniculate bodies, either in the fibers of the optic radiation or in the visual cortical centers. If, on the other hand, when the light is carefully thrown on the hemiopic half of the retina, the pupil remains inactive, the conclusion is justifiable that there is interruption in the path between the retina and the geniculate bodies, and that the hemianopsia is not central, but dependent upon a lesion situated in the tract.
