    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.

    Hydroxychloroquine or chloroquine ingestion can cause atrophy of the retinal pigment epithelium in the form of a bull’s eye maculopathy in cases of chronic use. Early detection of toxicity prior to the development of the bull’s eye is important, as loss of visual acuity is usually irreversible at that stage. May 16, 2011 Retinal photograph showing classic “bull’s eyeretinopathy of hydroxychloroquine toxicity, which represents atrophy of the retinal pigment epithelium. This is a relatively late change, and good screening can detect toxicity before any bull’s eye is visible. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. It is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus.
