    Although their therapeutic and toxic doses differ, they are related drugs with similar clinical indications for use and similar manifestations of retinal toxicity.

    Most cases of chloroquine retinopathy have developed when a higher than currently recommended 3 mg/kg/day using lean body weight dose was used. 21 A daily dose exceeding 250 mg with a total cumulative dose between 100 and 300 g is customarily needed to produce toxicity. 22 One study showed a 19% incidence of chloroquine retinopathy in patients taking a mean daily dose of 329 mg. 23 On the other hand, with strict adherence to a low dose per day, the incidence of retinal abnormalities is. Retinal toxicity from chloroquine CQ and its analogue, hydroxychloroquine HCQ, has been recognized for many years. Chloroquine toxicity remains a problem in many parts of the world, but is seen less frequently in the United States where the drug largely has been replaced by HCQ. However, a very close eye needs to be kept on this child as life-threatening toxicity may evolve rapidly. It is prudent to intubate a patient with a potentially significant chloroquine overdose if there is any significant depression of consciousness level or cardiovascular instability.

    Retinopathy may be asymptomatic or may cause central or paracentral scotomas leading to difficulty reading or performing fine visual tasks (due to parafoveal metamorphopsia).

  6. Bull's-eye maculopathy due to hydroxychloroquine toxicity. Chloroquine and hydroxychloroquine can cause toxic retinopathy due to their binding of melanin in the retinal pigmented epithelium RPE as well as direct toxicity to retinal ganglion cells. Early findings include mottling of the RPE and blunted foveal reflex.

    The usefulness of hypokalemia as an indicator in the evaluation of chloroquine toxicity was studied in a retrospective series of 191 acute chloroquine poisonings. Results indicated that the risk of severe poisoning and death are proportional to the degree of hypokalemia. Hydroxychloroquine can cause irreversible retinal toxicity, resulting in bilateral bull’s eye retinopathy, but is regarded as less toxic to the retina than chloroquine and it does not cause the corneal deposits seen with chloroquine therapy. Chloroquine retinopathy, is a form of toxic retinopathy damage of the retina caused by the drugs chloroquine or hydroxychloroquine, which are sometimes used in the treatment of autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus. This eye toxicity limits long-term use of the drugs.
