Scotoma Paracentral

Paracentral scotoma is a pathology of the optic nerves and optical system of the eye. This means that the condition is caused by dysfunction of the optic nerves or the neural component of the retina. The area of ​​nerve structures, including the optic nerves and retinal nerve tissue, is located in the occipital lobe of the brain. The visual perception centers are controlled by the same brain structures that control language coordination, sequential speech, emotion, and motor coordination.

The area that is typically associated with visual neural structures is called the occipital region of the brain. The occipital (retrocerebral) area of ​​the brain dominates the nearby visual cortex of the brain. In the temporal lobe, this primary visual cortex is located to the right of the raphe, but is on the left side in most patients with paracentral scotoma. The visual cortex area is 42 mm wide from front to back and 30 mm long from the side. This size allows for logical interpretation. Most of the space posterior to the center of the layered neuronal cortical map of the occipital region is occupied by the occipital-subcortical tag-associative auditory visual nerve field (ASSRF), which is associated with the basic functions of music and speech processing. The center for the association cortex is approximately 78 mm posterior, leaving < 12 мм позади. Очевидно, требуется меньше этого расстояния, чтобы попасть в зрительные центры в центральной части затылочных разделов мозга.
