Evoked potentials (EPs) to photic stimulation in the occipital cortex were investigated in 28 patients with homonymous hemianopia caused by a focal lesion of the visual system. Asymmetry of the EPs in the two hemispheres was recorded only in cases of complete homonymous hemianopia. A reduction in the response on the side contralateral to the hemianopia was observed in patients with lesions of the visual pathways at the level of the optic tract and as a result of the spread of the pathological focus to the occipital lobe. In patients with a lesion affecting predominantly the mediobasal zones of the temporal lobe and with homonymous hemianopia caused by a lesion of the optic radiation, responses in half of the cases were higher in amplitude on the side of the focus or were recorded only in the deafferented occipital region. |
