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.

Ophthalmology Chloroquine retinopathy, is a form of toxic retinopathy damage of the retina caused by the drugs chloroquine or hydroxychloroquine, which are sometimes used in the treatment of autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus. This eye toxicity limits long-term use of the drugs. The use of hydroxychloroquine HCQ, an antimalarial drug utilized for a range of rheumatologic and dermatologic diseases, is associated with a low incidence of retinopathy 0.5% when used at recommended doses 6.5 mg/kg per day. 1 It has largely replaced chloroquine because of decreased ocular toxicity at high dosages, 2 but can still lead to potentially irreversible visual loss. 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.
