ABSTRACT
The aim of the study was to evaluate blood flow in ocular vessels and the carotid arteries of patients with various clinical forms of ischemic ocular lesion (IOL). The subjects were 165 patients with IOL aged 35 to 70 years. Of these, in 115 patients the lesion was acute, and in 50 patients it was chronic. Ultrasound examination using Doppler color mapping (DCM) and energetic mapping (EM) was performed to evaluate ocular and carotid blood flow. The use of DCM and EM made it possible to detect hemodynamically significant changes in acute and chronic IOL in carotid arterial pathology. Duplex scanning of the carotid arteries allowed for timely diagnostics of occlusive-stenotic carotid arterial lesion and determination of atherosclerotic plaque type. DCM and EM are highly informative methods of diagnostics of pathological vascular changes in IOL.

The paper describes management results of 56 patients with occlusive and stenotic atherosclerotic lesions of carotid arteries, complicated by different forms of ocular ischemia. Complex assessment (duplex scanning, color Doppler mapping, transcranial Doppler) before and a year after carotid endarterectomy revealed a significant improvement in objective parameters of ocular hemodynamics: registration of antegrade blood flow in ophthalmic artery, the rise of maximal systolic blood flow velocity and decrease of resistance index in ophthalmic, central retinal and posterior ciliary arteries.
