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. Who can do plaquenil test Chloroquine phospahe absorbance nm Toxic maculopathy is a form of retinal toxicity that is associated with antimalarial agents such as plaquenil and chloroquine. Both medications are commonly used to treat patients with systemic autoimmune diseases that include the following Plaquenil-induced toxic maculopathy was first described in 1967. Because the retinal damage from plaquenil is usually irreversible if present for a more prolonged period of time, it is important to detect the disease in its early stages. Executive Summary Recent data have highlighted that hydroxychloroquine retinopathy is more common than previously reported. The prevalence in long term use patients appears to be around 7.5% and depending on dose and duration of therapy 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.

FAF imaging may show distinct alterations due to toxic retinal effects of long-term chloroquine and hydroxychloroquine therapy. 84 Various methods have been proposed to detect early stages of chloroquine retinopathy. Abstract. 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. Jan 05, 2020 Hydroxychloroquine retinopathy is most influenced by daily dose and duration of use. Risk for toxicity is less with 5.0 mg/kg real weight/day for hydroxychloroquine and 2.3 mg/kg real weight/day for chloroquine. Patients are at low risk during the first 5 years of treatment.
