    On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye.

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. A baseline ocular examination is recommended within the first year of starting PLAQUENIL. The baseline exam should include best corrected distance visual acuity BCVA, an automated threshold visual field VF of the central 10 degrees with retesting if an abnormality is noted, and spectral domain ocular coherence tomography SD-OCT.

The adult dose of Plaquenil to suppress malaria is 400 mg on the same day each week. The pediatric weekly suppressive dosage is 5 mg/kg of body weight. The adult dose of Plaquenil to treat an acute attack of malaria is an initial dose of 800 mg followed by 400 mg in six to eight hours and 400 mg for two more days. Irreversible retinal damage observed in some patients who had received hydroxychloroquine sulfate; significant risk factors for retinal damage include daily doses of hydroxychloroquine sulfate greater than 6.5 mg/kg 5 mg/kg base of actual body weight, durations of use greater than five years, subnormal glomerular filtration.

    Mechanisms of drug action and resistance The major action of chloroquine is to inhibit the formation of hemozoin Hz from the heme released by the digestion of hemoglobin Hb. The free heme then lyses membranes and leads to parasite death. Chloroquine resistance is due to a decreased accumulation of chloroquine in the food vacuole.
