Mislocalization in Visual Space

Abstract

Nineteen patients with homonymous visual field defects due to cerebral lesions mislocalized targets at the midline of the visual field, or at the midvertical boundary of homonymous visual field defects. The mislocalization was to the "good side" and away from the patient. Eight patients with temporal hemianopias due to lesions of the optic chiasm localized targets correctly. It is postulated that the mislocalizations at the vertical border and in depth are due to other concomitant cerebral dysfunctions caused by the brain lesion. Such patients demonstrate a change in their entire visual perception, not only in the blind field.
