One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine Plaquenil, a chloroquine derivative. The risk of developing retinal toxicity has been found to be dependent on the daily HCQ dose and the duration of use. The risk of retinal toxicity is 1% for those who use HCQ for up to 5 years and 2% for those who use HCQ for 5–10 years, but it rises to almost 20% after 20 years of HCQ use.
