Answer

Vision damage that occurs before initiation of therapy is often irreversible, [43] especially in patients who have other ischemic complications. [44] In patients whose vision loss is initially unilateral, the second eye may become affected even after the initiation of treatment (possibly because those vessels have already been affected by arteritis) in 6-13% of patients. [45]
