Chloroquine has been associated with keratopathy more than hydroxychloroquine. Older studies have shown a decrease in corneal sensation in approximately 50% of patients taking chloroquine. Toxicity from hydroxychloroquine may be seen in two distinct areas of the eye the cornea and the macula. The cornea may become affected relatively commonly by an innocuous cornea verticillata or vortex keratopathy and is characterized by whorl-like corneal epithelial deposits. These changes bear no relationship to dosage and are usually.
