[Case of Horton's arteritis with development of simultaneous bilateral amaurosis]

The Authors report a case of temporal arteritis which started with a sudden onset of bilateral amaurosis. They considered this case worth recording, on account of its unusual and striking way of manifestation. Moreover, the importance of an early diagnosis of the disease is underlined, since an adequate steroid therapy, carried out in time, often allows to avoid the serious complications which may arise, particularly blindness. Recent epidemiological studies which showed the elevated incidence of the disease in patients above the age of 50, underline the necessity of considering temporal arteritis as one of the diagnostical possibilities, even if the symptomatology is defective or unclear.
