Optic neuropathy with vision loss is an uncommon but serious event currently considered a probable amiodarone-associated adverse drug reaction. We report a case of a 72-year-old woman with irreversible, bilateral, and sequential vision loss experienced while taking amiodarone. This case involves challenge, discontinuation and subsequent rechallenge with amiodarone. It provides evidence for reclassifying optic neuropathy as a certain adverse drug reaction. Despite relatively low incidence of vision loss in patients receiving amiodarone, we agree with recommendations of baseline and periodic ophthalmic examinations during therapy. Due to potentially irreversible vision loss, patients taking amiodarone should seek medical attention for visual changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
