Amiodarone is a commonly used antiarrhythmic used to treat atrial fibrillation and ventricular tachycardias. While this agent can present with pulmonary, thyroid, and hepatic side effects, it can also, less commonly cause neurologic toxicity, particularly optic neuropathy. Optic neuropathy can manifest as acute vision loss. The management of amiodarone-associated optic neuropathy (AAON) includes early recognition of symptom manifestation so that the medication can be discontinued promptly. Here, we describe a case of a 64-year-old male who developed acute onset complete left-sided vision loss after initiation of amiodarone.
Keywords: acute vision loss; amiodarone associated optic neuropathy; drug-induced optic neuropathy; neurological side effects of amiodarone; side effects of amiodarone; sudden vision loss; toxic optic neuropathy.
