[Ocular changes in systemic atherosclerosis]

Up-to-date aspects of ocular changes in systemic atherosclerosis are reviewed. At the present time despite of wide use of current methods of ocular blood circulation and retina examination there are no papers that allow to estimate dynamics of impairment of visual functions from different viewpoints (clinical, functional, blood flow, morphological etc.) in initial isolated ocular atherosclerosis. Etiology, pathogenesis and ideas about potential effect of systemic atherosclerosis on the eye are discussed. Features of blood flow in optic nerve head compared to retinal vessels are described. According to the last data correlation between the degree of reduction of a-wave of scotopic electroretinogram and deterioration of haemodynamic parameters exists.
