Flash visual evoked potentials and psychophysiological indicators of the visual system with visual acuity "hand motion"

The purpose of the study is to investigate the distribution of the amplitude and time parameters of visually evoked potentials and their relationship with the psychophysiological indicators of the visual analyzer in visual acuity "hand motion". Material and Methods. Data from 85 eyes were analyzed: 36 eyes with predominant impairment of retinal functions, 36 eyes with predominant impairment of the optic nerve, and 13 eyes with the predominant impairment of the optical media of the eye. The LED flash response was registered on the Neuro-MVP-4 device. The severity of detection was assessed using the CAMEL software. The threshold of electrical sensitivity was measured on the ESOM-Comet device. Results. All the parameters under study had a significant variation. The latency of flash VEP components had statistically significantly higher values in the group with predominant dysfunction of the optic nerve (p
