The symptoms and syndromes associated with visual impairment that occur in acute cerebrovascular accident (OMNA) of various parts of the brain are quite characteristic, can develop with circulatory disorders in various arteries of the brain and depend on the severity of damage to brain tissues. Disorders of vision and oculomotor functions, including decreased central vision, impaired peripheral vision, limited eye mobility and impaired visual perception, are widespread among patients who have suffered a cerebral stroke. This article is the first part of a two-part review devoted to the problem of visual impairment in patients with acute cerebral circulatory disorders. In the first part, we examined the prevalence and diversity of such violations. The second part will provide an overview of the methods of rehabilitation of patients in this category. Main content of the rewiew. The data of the analysis of the prevalence of various types of visual impairments in patients who have undergone ONMC are presented, based on publications in international and domestic databases OpenAlex, Scilit, Lens, PubMed, Cyberleninka and eLibrary.ru available for analysis by August 15, 2024, with a search depth of mostly 15 years. As a result of the search, 52 articles on a given topic were reviewed. In addition, 5 sources dated from an earlier period (1989–2000) were used, as they contain the necessary information within the framework of this review. Conclusion. Visual impairment entails a significant decrease in the quality of life of such a category of patients. To obtain a complete picture of the patient’s condition after a cerebral stroke, it is necessary to conduct a thorough targeted screening of visual impairment. This will allow you to take timely measures to restore visual functions, which may have a beneficial effect on further rehabilitation.
