Right visual hemiagnosia: a single case report.
A patient with an infarct in the territory of the left posterior cerebral artery, but without campimetric deficits presented with some reading difficulties and a visual agnosia restricted to the right visual field. Although the patient was able to match accurately in his agnosic field, he was unable to name or otherwise identify objects. The implications of this case for the anatomical substrates of visual processing and the functions of each hemisphere are discussed.
