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. Chloroquine maculopathy dose Hydroxychloroquine side effects dry eyes Chloroquine diphosphate intercalator dna Chloroquine primaquine combination HCQ retinopathy is typically asymptomatic in patients who are in the early stages of the disease, according to a 2015 study published in the Indian Journal of Ophthalmology by Hemang K. Pandya, MD. These usually consisted of alteration in retinal pigmentation which was detected on periodic ophthalmologic examination; visual field defects were also present in some instances. A case of delayed retinopathy has been reported with loss of vision starting one year after administration of hydroxychloroquine had been discontinued. If you take Plaquenil, it is very important to see an ophthalmologist regularly. Your ophthalmologist will check your retina for problems before serious damage occurs. Next 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.

Plaquenil toxicity cumulative doseHydroxychloroquine cancer stem cells Plaquenil hydroxychloroquine is in a class of drugs called disease-modifying anti-rheumatic drugs, which are used to decrease inflammation, pain and joint damage. While today it is used to treat autoimmune conditions, such as rheumatoid arthritis and lupus, it was originally used as an anti-malaria drug. Plaquenil Side Effects on Your Eyes and Vision.

Hydroxychloroquine, on the other hand, is much less toxic to the retina and there have been fewer reported eye problems. In general, a baseline ophthalmic examination should be performed upon initiation of therapy. Baseline Examination All patients should have a baseline ophthalmologic examination within the first year of initiating HCQ or CQ therapy with thorough risk factor assessment and fundus examination of the macula to rule out underlying disease. Baseline visual field and SD OCT are recommended if abnormalities are present e.g. macular lesions, glaucoma, etc that could affect screening tests. Furthermore, the advent of novice sensitive diagnostic modalities has led to a revision of the recommended guidelines for patients using Plaquenil see “2011 Plaquenil Screening Tests”. 7 A dilated fundus examination is critical in detecting and documenting established macular or retinal disease; however, due to low sensitivity, it should not be used as a screening test alone.
