ANALYSIS OF THE RESULTS OF THE STUDY OF VISUAL EVOKED POTENTIALS DEPENDING ON THE STAGE OF OPTIC NEURITIS
Abstract
The functional visual impairment of the optic nerve was confirmed by the method of visual evoked potentials. In 1-4 groups of patients with optic neuritis, the N75 and P100 latency increased. An increase in latency indicates a lesion of the myelin sheath, which is associated with a decrease in the rate of potentials in the optic nerve. The analysis of the amplitude of the VEP revealed a significant increase in this index in groups 1 and 2 and a decrease in groups 3 and 4 as compared to the control group. The decrease in the amplitude of the VEP is associated with blockade of impulses, due to axial axonal cylinder damage.
