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. Plaquenil and hair growth Plaquenil first dose The presence of bull’s-eye maculopathy indicates the disease has been progressing for years, resulting in foveal thinning and likely vision loss. 8 SD-OCT is a highly sensitive and reproducible imaging modality used in the detection of Plaquenil retinal toxicity. The preferential loss of photoreceptor IS/OS junction makes SD-OCT an ideal tool. Plaquenil hydroxychloroquine belongs to a group of medicines called quinolines. Plaquenil is used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. Plaquenil hydroxychloroquine is an anti-malaria oral medication that is more commonly prescribed in the US for inflammatory conditions like systemic lupus erythematosus, rheumatoid arthritis, and Sjogren's Syndrome. This medication can help combat the crippling side effects of chronic inflammation, but it is not without its own potential risks. 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.

Apr 20, 2011 Although the incidence of macular toxicity is infrequent with Plaquenil use at a dosage of 200mg or 400mg q.d. its visual impact can be devastating. 2,3. The associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area. In early toxicity there are no visible signs, but field, OCT and mfERG changes can be detected. If abnormalities are present only unilaterally, investigate other causes besides hydroxychloroquine toxicity see “Differential Diagnosis of Bull’s-Eye Maculopathy”.
