Optic Nerve Dysfunction in a Child Following Low-Dose Maternal Warfarin Exposure

Abstract

Because the embryopathy associated with maternal warfarin use seems dose-dependent, some physicians advocate low-dose warfarin for pregnant women requiring anticoagulation. The current case, however, highlights that optic nerve dysfunction (as well as other signs of warfarin embryopathy) can occur after low-dose maternal warfarin exposure.
