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. Hydroxychloroquine or sulfasalazine Plaquenil side effects kidney How dangerous is hydroxychloroquine Plaquenil sleeplessness The new guideline on screening for hydroxychloroquine and chloroquine retinopathy is written in response to evidence from the United States that shows that hydroxychloroquine retinopathy is more common than previously recognised. Implementation of the guideline’s recommendations will prevent iatrogenic visual loss. The new guideline also makes recommendations regarding the techniques and. If a 24-2 or 30-2 field is performed, be way of overlooking the 2-degree field of sparing seen on 10-2 fields; in these tests, a small central defect may be seen instead. The area of risk on a 10-2 Humphrey visual field is typically two to six degrees from the center in non-Asian patients, although exceptions of course exist. Visual Fields Early drug toxicity can cause bilateral, relative paracentral scotomas4 Defects can be present BEFORE definitive signs are seen on fundus examination. A white-on-white 10-2 threshold visual field is recommended.19 • Want to pay close attention 2-6 degrees from fixation21 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.

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. Recommendations on Screening for Chloroquine and.. Early Plaquenil Toxicity Detected without Bull’s Eye Maculopathy. Humphrey visual field findings in hydroxychloroquine toxicity. To quantify the variability of scotomas detected by 10–2 visual field VF testing with a red target in patients taking hydroxychloroquine without and with retinopathy. Retrospective review of clinical charts and VFs. Twenty-four patients taking. Apr 20, 2011 Subjective testing of the central visual field was recommended to uncover early functional changes associated with paracentral scotomas. Paracentral scotomas have been reported prior to the associated maculopathy, so an amsler grid test or central 10-2 visual field perimetry was recommended. 2,5 Upon the detection of the visual field defects, the hydroxychloroquine was stopped. She was taking hydroxychloroquine 5.0 mg/kg/day with a duration of 10 years with a cumulative dose of 1460g putting her at increased risk for hydroxychloroquine retinal toxicity.
