[Visual evoked potentials in patients with a history of non-traumatic intracranial hemorrhage]

The authors present the results of preliminary investigations of visual evoked potentials in patients long after intracerebral haemorrhage. In 32 studied patients prolongation was observed of the latency of waves N1 and N2 as well as P1, and this prolongation was more pronounced in the case of stimulation of the eye contralateral to the hemisphere with the lesion. This asymmetry of latency occurred with similar irregularity in case with all locations of the lacuna, with the exception of the occipital lobe. In the latter case a much greater prolongation of Ni and Pi latency on the affected side.
