Abstract
Ophthalmodynamometry, or the measurement of ophthalmic artery pressures, has been demonstrated to be of value for diagnosis of stenosis or occlusion of the internal carotid artery.1,2 Since it has been estimated that more than 20% of infarctions of the cerebral hemispheres are caused by such lesions, ophthalmic artery pressures should be measured in all patients with symptoms of cerebral vascular insufficiency. Many physicians have not mastered the technique of ophthalmodynamometry because they fear the possibility of injury to the patient by application of the foot of the pressure gauge to the sclera of the eye or because they lack skill in the use of an ophthalmoscope. In order to circumvent these two drawbacks, I have found the following to be a quick and easy method for determining the relative arterial pressures in the two eyes. Instead of the customary method of using an ophthalmoscope to visualize the central retinal
