    Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

    Dosage. The 2002 recommendations considered a daily dose at or below 6.5 mg/kg/day of hydroxychloroquine to be low-risk for subsequent toxicity. Hydroxychloroquine is dispensed in 200 mg tablets, so an “average” 70-kg patient using the common dose of 200 mg bid actually would be receiving a slight overdose according to this threshold. The toxic dosage for chloroquine was derived from hydroxychloroquine retinal toxicity studies, although no definitive data have shown pharmacologic equivalence. 1 The first reports of retinal toxicity attributed to chloroquine appeared during the late 1950s. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress. It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects.

    Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

  7. Factors that increase the risk of developing hydroxychloroquine associated retinal toxicity include daily dose, cumulative dose, renal or liver impairment, older age, and prior retinal disease. Specifically, a daily dose of 6.5mg/kg based on ideal body weight and a cumulative dose of 1000g of hydroxychloroquine or 460g of chloroquine are both considered risk factors for retinal toxicity.

    Recommendations on Screening for Chloroquine and Hydroxychloroquine Retinopathy Retinal toxicity from chloroquine CQ and its analogue, hydroxychloroquine HCQ, has been recognized for many years. Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been. Chloroquine and hydroxychloroquine both belong to the quinolone family and share similar clinical indications and side effects, including retinal toxicity. Chloroquine-induced retinal toxicity was first described in 1959 and the retinal toxic effects of hydroxychloroquine were later described in 1967 3, 4. PURPOSE To define the risk of hydroxychloroquine HCQ-related retinal toxicity in patients with rheumatoid arthritis RA and systemic lupus erythematosus SLE who are receiving recommended dosages of the drug or =6.5 mg/kg/day.
