title: Amaurosis fugax and retinal vasculitis associated with methamphetamine inhalation.
abstract: A 26-year-old male drug abuser developed amaurosis fugax followed by retinal vasculitis in the right eye after nasal inhalation of methamphetamine. He gradually recovered, but required prolonged systemic corticosteroid therapy. We believe that the amaurosis fugax was due to drug-induced vasospasm and that the retinal vasculitis was a drug-induced hypersensitivity vasculitis.
