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.

It is seen in Fabry disease or in case of prolonged amiodarone intake. Causes Amiodarone Fabry’s disease Chloroquine Hydroxychloroquine Indomethacin Phenothiazines etc. 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. 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. 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.

Hydroxychloroquine, sold under the brand name Plaquenil Sanofi-Aventis, is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2 Retinal toxicity associated with HCQ use is relatively rare, estimated at 1 percent after five years and rising with continued therapy. 3 However. Cornea verticillata; Vertex keratopathy Chloroquine toxicity is characterized by whorl-like corneal epithelial deposits. Medications of the chloroquine family, including chloroquine Nivaquine. The cornea may become affected relatively commonly by an innocuous cornea verticillata or vortex keratopathy and is characterized by whorl-like corneal epithelial deposits. These changes bear no relationship to dosage and are usually reversible on cessation of hydroxychloroquine.
