| Abstract | n engl j med 373;17 nejm.org october 22, 2015 1677 — ocular ischemia resulting from the intravenous injection of drugs of abuse. A 26-year-old woman presented to our emergency department with blurred tunnel vision after the intravenous injection of cocaine and methamphetamine into her neck vessels.1,2 She indicated that her use of this site of injection was longstanding and that she had unintentionally punctured her carotid artery on several occasions. On presentation, her visual acuity was 20/30 in both eyes. On examination, visual-field testing revealed constriction of peripheral vision in both eyes and no pupillary defects. Optic neuropathy with pallor of both optic disks was identified. The retinal arteries were markedly narrowed and beaded in appearance, and the retinal veins were mildly dilated. Pinpoint erythematous marks were noted at the injection sites, and ultrasonography of the vessels and soft tissues on both sides of the neck revealed no abnormality. We suggest that clinicians obtain a detailed history of both recent and past injection-drug use when evaluating patients with acute or chronic optic neuropathy. |
