• An objective method of registering the pupillomotor threshold was utilized to demonstrate pupillary hemiakinesia (Wernicke hemianopic phenomenon) in five patients with homonymous hemianopsia due to lesions above the lateral geniculate body. The results show that Wernicke hemianopic pupillary response is of no diagnostic value in differentiating between proximal lesions and those distal to the lateral geniculate body.
