The diagnosis in this case is amiodarone corneal verticillata, producing corneal epithelial eruption and abscess secondary to a sudden large increase in dosage. Upon further history, the patient explained that she began seeing a new cardiologist six weeks earlier; that doctor tripled her daily dosage of amiodarone from 100mg to 300mg.
