Ocular pressure studies in the diagnosis of carotid artery disease

This report describes changes seen in the eyes of a group of patients with carotid artery disease and defines the value of recognizing these pressure abnormalities in the diagnosis and management of carotid artery disease. Emphasis is given to small pressure pulses, a 'prolonged initial fall' response in tonography, low retinal artery pressure, lower applanation ocular pressure, and in some instances reduced ocular rigidity. This report is the result of studies performed over 6 yr, utilizing a systematic approach and a sensitive method of permanently recording ocular pressure pulses.
