Magnetic Resonance Tractographyas a Method of Choice for Neuroimaging in Ocular Ischemic Syndrome against the Background of Hypertension

Abstract

In recent years, there has been an increase in ischemic eye diseases. To a large extent, the clinical picture of ischemic damage to the posterior segment of the eye is due to the peculiarities of the blood supply to the optic nerve and retina. Acute circulatory disorders in the retina and optic nerve almost always lead to either partial loss of vision or blindness. The prognosis is always serious, but not hopeless. Sometimes, under the influence of treatment, an improvement or stabilization of the process may occur. Repeated courses of treatment are often required.With GIS, circulatory disorders can occur both in the vessels of the organ of vision and in the system of the main intracranial and extracranial vessels of the head, which feed the intracranial sections of the optic nerve and the central part of the visual analyzer [1, 6]. Thus, changes in capillary circulation and microcirculation disorders are of great importance in the development of damage to the nerve cells of the optic nerve. In the process of circulatory disorders in the capillaries, degeneration of the nervous tissue occurs, which is especially sensitive to any negative changes in metabolism [9, 10]. In this regard, the development of new methods for early and differential diagnosis of HIS is an urgent problem of modern ophthalmology [3, 5, 6]. In such situations, neuroimaging methods come to the aid of a practical doctor , which not only assess the state of the brain, but also clarify the location and nature of the damage to nerve tissues.
