One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine Plaquenil, a chloroquine derivative. The actual incidence of retinal toxicity from hydroxychloroquine is difficult to pin down because there is usually a long time between being started on the drug and the start of any identifiable retinal toxicity. The overall rate of probable retinal toxicity is in the range of 1 of every 200 people treated. Our study showed that approximately 30% of the patients treated with HCQ had retinal toxicity. There was no association between retinal toxicity and sex, type of rheumatic disease, and daily HCQ dose. However, there was a positive correlation between retinal toxicity and age, cumulative HCQ dose, and duration of HCQ use.

Plaquenil-induced toxicity usually will not occur before five years of. There is an increased risk of HCQ retinopathy with increase in the cumulative dose. Per the prior 2011 AAO guidelines the recommended maximum dose to minimize HCQ retinal toxicity was 6.5 mg /kg based on ideal body weight 2. The advantage of the real body weight formula is that it distributes the risk evenly on a broad range of body habitus.
