A bstract : Interest in the extracerebral circulation, particularly in the elderly, has led to new methods of estimating blood pressure in the carotid arteries. The method described here involves use of the ophthalmodynamograph, which simultaneously monitors orbital blood pressure and brachial artery blood pressure. The study was made on 66 patients in a geriatric day hospital. The 53 females (average age, 76) and 13 males (average age, 70) had multiple disease. The five most common diagnoses were cerebrovascular accident with hemiplegia (18 cases), osteoarthritis (10 cases), cerebral arteriosclerosis (9 cases), ischaemic heart disease with congestive failure (9 cases), and parkinsonism (6 cases). In 120 eyes, the orbital diastolic pressure varied from 50 mm to 135 mm Hg, being between 80 and 100 mm in 50 per cent and below 80 mm in 27 per cent. The orbital diastolic pressure often was greater than the brachial; in 10 cases the difference was greater than 20 mm. When the diastolic pressures in the two eyes were compared, 9 cases showed a difference greater than 10 mm and 24 cases a difference greater than 6 mm. Problems exist regarding the interpretation of certain waveform changes in the tracings. However, the apparatus is reliable, safe, and easier to use than most available techniques for studying blood flow in this region.
