[Vision disorders as manifestations of transient ischemic attacks in the vertebrobasilar basin]

Vision disorders caused by ischemia of the cerebral occipital cortex in the presence of transitory ischemic attacks in the vertebral basilar basin are described. Relationship between complaints of vision disorders and severity and frequency of transitory ischemic attacks is analyzed. Exogenous factors provoking dysfunctions of visual and vestibular analyzers are discussed. Correlation between visual disorders and cerebral hemodynamic disorders and vertebrogenic changes in various patterns of transitory ischemic attacks is analyzed. The number of complaints of visual analyzer dysfunction is increased by 1/3 in the patients with dyscirculatory abnormalities. One of the key symptoms of hypofunction of the stem mesencephalic compartments is paralysis or paresis of the eyeball convergence, which was recorded in 38% patients.
