Amiodarone is a class III antiarrhythmic drug that is commonly used for a wide variety of cardiac arrhythmias. Amiodarone will induce mitochondrial deposits in the deep epithelial layer of the cornea. These deposits will form a whorl-like epitheliopathy called "corneal verticillata," or vortex keratopathy. The deposits are barely visible without the aid of a slit lamp and rarely result in any reduction in vision or ocular discomfort. The corneal verticillata are typically found on routine eye exam and are not an indication for discontinuation of the medication. Most patients using amiodarone will develop corneal deposits. Upon discontinuation of the medication, the deposits typically resolve.
