[Morphology of changes in records of visual evoked potentials in patients with multiple sclerosis].

Statistical analysis of the parameters of the waves of visual evoked potentials were performed in 2 groups: in 32 patients with a sure diagnosis and in 21 with a probable diagnosis of multiple sclerosis. In the 1st group prevailed the reduced record with a delayed latency of peaks of the A, B, C waves and with the interhemispherical and interocular asymmetry of the diagram. In the 2nd group dominated an delayed latency of the B and C waves and interhemispherical asymmetry of those waves. Abnormal characteristic of the record was obtained also after stimulation of the eyes of the examined patients with a full visual acuity.
