    Plaquenil visual field defects


    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.

    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. Although visual field defects in HCQ toxicity can be highly variable in terms of the depth of defect, all our patients showed a similar pattern on 10-2 white, with the same areas affected. However, one needs to look carefully for subtle decreases in threshold in the area at risk 2–6 degrees from center. A localized defect in the visual field bordered by an area of normal vision. This occurs with a variety of eye diseases e.g. retinal diseases and glaucoma; optic nerve diseases, and other conditions. Localized defect in the visual field bordered by an area of normal vision.

    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.

    The Humphrey visual field 10-2 white stimulus was reliable, showing bilateral, although asymmetric, patchy parafoveal visual field defects Figures 4a and 4b. She was educated on the ocular effects of Plaquenil and the continuous monitoring and management. The corresponding prescribing physician was also advised on the findings. Results Seventeen eyes from 10 patients illustrated abnormalities with OCT and normal HVF testing. These OCT alterations included 1 attenuation of the parafoveal ellipsoid zone and 2 loss of a clear continuous interdigitation zone. Several eyes progressed to advanced parafoveal outer retinal disruption and/or paracentral visual field defects. Visual field abnormalities occurred in 35 patients. Five patients developed hydroxychloroquine ocular adverse effects, of which 4 were visual field defects and 1 was significant vortex keratopathy. None of these patients developed visual symptoms, changes in visual acuity, or fundus abnormalities resulting from drug toxic effects nor did they have any color vision defects.

    Plaquenil Hydroxychloroquine - Side Effects, Dosage. Plaquenil is the brand name for the prescription drug hydroxychloroquine. It's used to treat and prevent malaria infection, and to reduce symptoms and progression of autoimmune diseases such as lupus, rheumatoid arthritis, and others. Malaria is spread by mosquitoes.
