Cornea VerticillataThis is a whorl-like opacity in the corneal epithelium seen in patients on long-term treatment with medication such as amiodarone, chloroquine, phenothiazines and indomethacin. It is also seen in patients with Fabry disease and its carrier state. The condition is generally asymptomatic, harmless and reversible on stopping the drug. The whorl-like pattern shows the direction of migration of corneal epithelial cells. Occasionally the condition had been known to cause glare and surface discomfort which response to topical lubricants.
