    Disease Entity. Hydroxychloroquine Plaquenil and chloroquine cause ocular toxicity to various parts of the eye such as the cornea, ciliary body, and retina. Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported. Chloroquine is rapidly and almost completely absorbed from the gastrointestinal tract, and only a small proportion of the administered dose is found in the stools. Approximately 55% of the drug in the plasma is bound to nondiffusible plasma constituents. Excretion of chloroquine is quite slow, but is increased by acidification of the urine. The two main ocular effects of chloroquine are reversible corneal deposits and irreversible retinal toxicity. Corneal deposits. Corneal deposits occur rapidly in 90% of patients on chloroquine. They are usually asymptomatic; however, patients can experience transient halos and heightened light sensitivity.

    In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology. Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine.

This possibly indicates that it is the drug itself which is deposited in the corneal.
