[Pathological convolutions of internal carotid arteries as one of the causes of visual dysfunction in children].
Visual evoked potentials (VEP) in response to reverse chess patterns were studied in 68 patients aged 7-14 years with pathological convolutions of internal carotid arteries and 25 healthy children. The latent period was increased and the amplitude of P100 peak decreased in the patients, which was indicative of dysfunction of the visual route. VEP changed at early stages of cerebral circulation insufficiency. The relationship between hemodynamic parameters and VEP values was proven. Increased latent period and decreased amplitude of the positive peak are the criteria of neurophysiological significance of pathological convolutions in the internal carotid arteries.
