Abstract

The analysis of scientific achievements of Russian and foreign authors in the field of applying visual evoked potentials (VEP) in today’s practical ophthalmology reflects the importance of this method for clarifying the physiological and pathophysiological processes in the visual system. The presented data indicate the significance of determining evoked potentials for the diagnosis and assessment of treatment quality in such visual system pathologies as the glaucomatous process and optic neuritis, as well as for the differential diagnosis of retrobulbar neuritis and optic tract pathology. Particular emphasis is placed on the importance of applying the VEP method for people living in the Arctic zone of the Russian Federation. The widespread introduction of this method for patients with amblyopia will contribute to a timely diagnosis and prognosis of this pathology in people living in the Russian Arctic. Being a complex anomaly in terms of its pathophysiological mechanisms, amblyopia remains insufficiently studied. The study of VEP in patients with amblyopia living in adverse climatic and geographical conditions of the Arctic zone of the Russian Federation will allow us to clarify the mechanisms of developmental changes in the visual system, its pathways and central parts. In addition, it will help to reveal predisposing factors for the formation of amblyopia in preschool children and identify disturbances in signal conductivity as well as changes in the work of the visual cortex. Of great relevance for contemporary practical and theoretical ophthalmology are the studies aimed to identify possible patterns of structural and functional abnormalities in children with amblyopia before and after therapy. Given the high medical and social significance of amblyopia in preschool children, further research on their VEP is required to clarify the pathophysiological features of the development of this condition.
