[Disturbances of the pupil reflex associated with homonymous hemianopic paracentral scotoma (author's transl)].

Four cases with isolated cerebral infarction near the occipital pole resulting in homonymous hemianopic paracentral scotoma showed loss of pupillomotor sensitivity within the scotomatous defects. This supports previous similar findings in patients with homonymous hemianopia due to larger infarctions in the posterior cerebral artery territory.
