[Evaluation of 524 cervicoencephalic Doppler studies in ocular pathology].

524 persons showing pathological ocular symptoms (hypertony, transient amaurosis, macular alterations, retinal vascular alterations, pigmentary retinopathy) underwent a cervicoencephalic Doppler test with echotomography. The results confirm the frequency and importance, in many cases, of latent cervicoencephalic degeneration: 12-27% of the subjects had important or very important atheromatous vessels, 25-42% with carotid endarterial plates, 1-10% with carotid stenosis (higher than 80%), 12-24% with alterations of the ophthalmic arteries. Such a noninvasive investigation is a very useful means to explore the hemodynamic and physiological status of the vascular surroundings of the eye and of the central arteries of the retina; it could be a very valuable tool for preventive and curative therapy.
