Complex Diagnostic of Ocular Blood Flow in Patients with Subclinical Atherosclerosis
Abstract
Purpose: to evaluate parameters of ocular blood flow in subclinical atherosclerosis. Materials and methods. We observed 45 patients aged from 40 to 65 years. The methods of investigation of the blood flow in orbital vessels and carotid arteries included duplex ultrasonography, Color Doppler Imaging and spectral Doppler analysis. Retinal vascular caliber was measured by using digital retinal photographs. Results. Color Doppler Imaging and spectral Doppler analysis of ocular blood flow showed significant increase of vascular resistance in central retinal artery and short posterior ciliary arteries, dilatation of retinal venular caliber in cases of subclinical atherosclerosis. Retinal venular caliber was significantly larger in individuals with subclinical atherosclerosis. Conclusion. Ultrasound methods of investigation of ocular blood flow and measurement of retinal vessel caliber showed the changes of choroidal and retinal circulation in patients with subclinical atherosclerosis.
