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.

Chloroquine and the less toxic hydroxychloroquine are used to manage inflammatory conditions such as rheumatoid arthritis and systemic lupus erythematosus. HCQ is widely used for the treatment of rheumatic diseases, particularly lupus and RA. It is generally well tolerated, but retinopathy is a concern. Retinopathy is rare, but is sight threatening, generally irreversible and may progress even after cessation of therapy. Hydroxychloroquine is a medication used to treat several conditions, including active rheumatoid arthritis, juvenile idiopathic arthritis, discoid and systemic and cutaneous lupus erythematosus, solar urticarial. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use.

They are related drugs with similar clinical indications for use and similar manifestations of retinal toxicity, although their therapeutic and toxic doses differ. Nov 01, 2015 Hydroxychloroquine is metabolized and secreted by both the liver and the kidneys. Therefore, disturbed renal or hepatic function might reduce HCQ clearance and increase the propensity for toxicity. Older age may also be associated with increased risk of macular toxicity, possibly due to the pre-existence of age-related macular changes that might not allow for the identification of early signs of toxicity.
