The visual tract (lat. tractus opticus) is an anatomically complex system of the central nervous system. It connects the human eyeballs with the visual areas of the brain, and also ensures the transmission of visual information from the neurons of the retina to the brain. The visual tracts form a separate part of the visual analyzer and are closely connected with the retina. With pathology of the optic tracts, various retinal neurons and their associated nuclei are damaged. To study visual formation, reflex tests are used - eye convergence, Jacksonian phenomenon, complete eye rolling. The diagnosis is established using various ophthalmoscopy methods. Optic circle syndrome is a disruption of the connection between the lateral geniculate body and the optic tract, manifested by turning off the image in the outer visual field. Appears with acoustic-gnostic symptoms and ataxia in the same side. Such manifestations are observed with damage to the lower parts of the frontal lobes. The development of visual circle syndrome in children often occurs against the background of a tumor process in the area of the craniovertebral junction or in the area of the diameter of the pons.
