Introduction. It is known that subarachnoid hemorrhages (SAH) resulting from the rupture of arterial aneurysms (AAs) can cause vision disorders, which is a significant factor in disability among the working population. The aim of the study is to investigate the features of oculomotor disorders in patients with SAH due to AA rupture. Materials and methods. The study involved 472 medical reports of patients in the acute period of AAs rupture. The mean age was 52 years, with 54.4% of patients being female and 45.6% male. Clinical-neurological and radiological methods, as well as statistical analysis were used in the study. Results. The presence of oculomotor disorders in aneurysmal subarachnoid hemorrhage is associated with a better treatment outcome, but it decreases the probability of discharge without neurological deficit (р<0.001). The rupture localization significantly affects its occurrence: internal carotid artery (ICA) ruptures (33.3%) notably increase risk (OR=3.2) compared to the anterior communicating artery (ACA) ruptures (29.5%) (р=0.003). Localization of AA rupture also influences the outcomes. In Group 1 the basilar artery (BA) ruptures (4.3%) correlate with mild neurological deficits, while in Group 2, ICA (33.3%) ruptures favor outcomes without deficits, unlike other regions, on example MCA (21.8%) and ACA (29.5%) (р<0.001). Conclusions. The presence of oculomotor disorders in aneurysmal SAH correlates with better treatment outcomes, but decreases the probability of discharge without neurological deficit. Rupture localization significantly impacts oculomotor disorder likelihood, with ICA aneurysms showing increased risk compared to ACA aneurysms. In terms of recovery, localization of the rupture is also significant: in Group 1 BA ruptures correlate with mild neurological deficits, while in Group 2, ICA ruptures favor outcomes without deficits, unlike other regions, for example middle cerebral artery (MCA) and ACA.
