Four cases are reported in which patients with temporal arteritis had impaired vision which was further compromised when they assumed the sitting or standing position. The possible complication of atheromatous stenosis of the cervical arteries in temporal arteritis is discussed. The use of the supine or shock position in treating recent loss of vision due to arterial occlusive disease is advised.
