Purpose: Study the peculiarities of the course of ocular ischemic syndrome on the background of cerebrovascular disease.Methods: The material for this study was the results of complex examinations of 37 patients (49 eyes) with OIS in combination with CCI. In order to study peculiarities of the course of OIS with CCI, in addition to a comprehensive ophthalmologic examination, used UC DM extracranial and intracranial segments of the great vessels of the brain, oftalmodopplerografy, MRI tractography. Quantitative characteristics of blood flow in the vessels of the eye and the brain were maximal systolic, end diastolic velocity, resistance index, carotid-ophthalmic ratio.Results: Analysis of the results of the study revealed a change in visual function in all patients to varying degrees, depending on the ratio of thedegree of destruction of MCA and ACA, OphAr, CRA and PSCA and maturities to experts. The data obtained Doppler examination of extracranial and intracranial segments of the great vessels and MR tractography correlated with changes oftalmodopplerografy, breach of visual acuity, and defects in the VF.Conclusion: Pathological changes of the extracranial and intracranial segments of arteries have a negative impact not only on the parametersof cerebral vascular circulation, but also exacerbate the violation of the parameters of blood circulation vessels of the eye, leading to the progression of OIS. Important in the development CCI and progression of OIS holds the consistency of collateral circulation. So, good consistency of collateral hemodynamics eliminates ischemia of brain and eyes tissue, and suffer less visual function.
