Abstract
Differences in ocular pulses from both eyes are well known to be associated with pathology; correlation of ocular pulse amplitude with the degree of carotid stenosis is made by a new method. Detection of ocular pulse is done by noncontact air-propagated ultrasound. Experimental results with dogs show detection of 10 to 15% carotid stenosis. By this method, one can screen for potential stroke in its incipient stages.
