Abstract
Two patients with altitudinal homonymous hemianopia caused by bilateral occipital infarctions were studied. Their clinical-computerized tomographic correlations showed the anatomic representation of the superior and inferior visual fields in the lower and upper banks of the calcarine fissure, respectively. The patient with the superior-field defect was unusual because he retained normal color vision and facial recognition abilities, despite having bilateral lesions that have classically produced central achromatopsia and prosopagnosia.
