    Jan 05, 2020 Risk for toxicity is least with less than 6.5 mg/kg/day for hydroxychloroquine and 3 mg/kg/day for chloroquine. Patients are at low risk during the first 5 years of treatment. Cumulative use in excess of 250 grams increases the risk for toxic retinopathy. Other risk factors include obesity, kidney or liver disease, older age. Although the drug has a relatively safe systemic profile, its use is associated with an increased incidence of macular toxicity––particularly if an individual has been on Plaquenil therapy for many years. 1,2 Specifically, a 2010 study indicated that the overall risk of Plaquenil macular toxicity increases by about 2% for every 10 to 15. Aug 29, 2014 Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure.

    While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula.

    Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. HCQ toxicity remains uncommon, but increases markedly with the duration of therapy and exceeds 1% after 5–7 years. Toxicity was unassociated with age, daily dosage, or weight. Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure.
