A 64- YEAR-OLD man experienced a 5-day history of recurrent episodes of transient visual loss in his right eye. He described the spells as resembling a black curtain falling across his vision, lasting seconds, and recovering within 1 minute. These attacks had been occurring several times per hour; he estimated that there had been at least 100 episodes. He had no relevant medical history and was taking no medication. He had not experienced headache, temporal pain, jaw claudication, or myalgias.
