Answer

The universally accepted treatment of giant cell arteritis (GCA) is high-dose corticosteroid therapy. [56, 23, 9, 25, 141] The major justification for the use of corticosteroids is the impending danger of blindness in untreated patients. Patients who present with visual symptoms have a 22-fold increased chance of visual improvement if therapy is started within the first day. Damage may be irreversible if treatment is delayed beyond 48 hours.
