dc.descriptionActuality. Blood circulation deficiency in the vertebrobasilar system is dangerous as it causes hypoperfusion and hypoxia in eye tissue. Despite the fact that changes in the eye caused by vertebrobasilar insufficiency have been called by different medical terms in the last 10 years, this disease is a group of pathologies that have not lost its relevance until now. Aims and objectives: early identification of signs of changes in the eye caused by vertebrobasilar deficiency and study of specific aspects of their clinical course. Material and methods. 20 patients of the first group, who were treated in the inpatient department of the Central Hospital of the Ministry of Internal Affairs of the Republic of Uzbekistan, underwent surgery to eliminate VBS blood circulation insufficiency (international classification of diseases (ICD) -10; G45.0), while 20 patients of the second group were treated conservatively, and their The analysis results of neurovisual and neurophysiological examination methods were compared. Results and discussion. Visual acuity recovery was 1.3 times higher in the first group than in the second group. These results were explained by the rapid recovery of hemodynamics, which were also reflected in the results of the computer perimetry study. In the second group, the average values of RNFL thickness were higher (169.5±14.8 μm), temple (105.4±7.8 μm), lower (191.4±15.0 μm) and nose (90.15±6, 47 μm) in the quadrant decreased compared to the first group. A statistically significant difference was found in the RNFL thickness of the upper (p<0.05), temporal (p<0.05) and lower (p<0.05) quadrants compared to the first group. Conclusions. The detection of scotomas in perimetry, which are not part of the defects detected during the OCT of the RNFL, indicates the presence of pathologies in the internal carotid artery in the chiasm, optic tract, or postgenicular optic tract. In such cases, it is appropriate to appoint patients to undergo MRI, and in cases where there are no changes in MRI, functional radiological examinations.en-US
