Impaired blood flow in various organs and tissues is a common cause of disabling disorders that even result in a lethal outcome. Despite an extremely rapid development of modern medicine, the rate of these disorders is still high thus emphasizing the importance of further detailed studies on this issue. In addition to systemic vascular diseases, local blood flow disturbances are also prevalent among population. These disturbances result from more significant blood flow disorders. Retinal vein occlusion is not an exclusion. Acute retinal vein occlusions account for more than half of ocular vascular diseases and may lead to extremely severe ophthalmic complications that result in poor vision, blindness, and reduced quality of life in both young and elderly patients. The diversity of clinical presentations, their severity, and clinical course make the diagnosis challenging thus altering the assessment of the prevalence of these diseases. Keywords: retinal vein occlusion, epidemiology, systemic vascular disorders, risk factors, retinal vessels. For citation: Moshetova L.К., Usharova S.А., Simonova S.V.,Turkina К.I.

Macular edema secondary to retinal vein occlusions is a significant complication affecting the vision. Medical treatment of retinal vein occlusions first started with intraocular steroid injections and then enriched with intraocular Anti-VEGF (Vascular Endothelial Growth Factor) injections. But till now the length and frequency of therapy have not been defined clearly. In this review, the use of bevacizumab in the treatment of branch retinal vein occlusion and macular edema will be summarized in light of the current literature.

Retinal vein occlusion (RVO) is a retinal vascular disease that severely impairs the visual function of patients. Observing the changes of retinal blood vessels before and after treatment is of great significance for the prognostic evaluation of RVO. The rapid development and widespread use of fundus imaging technique, especially ultra-wide-angle fundus fluorescein angiography (UWFFA) and optical coherence tomography angiography (OCTA) have made our observation of the retinal blood vessels of RVO more comprehensive and meticulous. In this paper, we reviewed the latest research progress of UWFFA and OCTA in RVO.

Macular edema (ME) is a nonspecific sign of numerous retinal vascular diseases. This paper is an updated overview about the role of inflammatory processes in the genesis of both diabetic macular edema (DME) and ME secondary to retinal vein occlusion (RVO). We focus on the inflammatory mediators implicated, the effect of the different intravitreal therapies, the recruitment of leukocytes mediated by adhesion molecules, and the role of retinal Müller glial (RMG) cells.

Assessment of the parameters of skin microcirculation is an urgent and important task of modern medicine in the development of methods for diagnosing diseases of the nervous system. The system for assessing the functional state of blood flow in the skin surface layers in the wavelength range from 400 to 850 nm has been improved based on the use of an extended mathematical model of the propagation of optical radiation in human skin by taking into account additional parameters: optical anisotropy of the skin, diameter and shape of erythrocytes in the dermis layer, blood pressure in the brachial artery in the range from 90/60 to 195/130 mm·Hg, plasma protein concentration in the blood (α1, α2, β1, β2, γ-globulins and fibrinogen, g/l), rheological properties of blood flow with a diameter of blood vessels from 4.5 to 500 microns in the skin surface layers, skin temperature from +35 to +41 °C. The developed system makes it possible to determine the severity of microhemodynamic shifts in relation to metabolic disorders, improve diagnosis and evaluate the treatment efficacy of a number of neurological disorders; it also made it possible to reduce the patient examination time and increase the accuracy of measuring the blood flow microcirculation parameters by 10 % (linear and volumetric blood flow velocities) to detect blood flow disturbances in the surface layers of the skin in the normal and abnormal condition of the nervous system.
