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.

Dec 04, 2014 Visual fields. The subjective component to HCQ retinopathy screening is an automated visual field testing the central 10° of vision. The earliest signs of HCQ retinopathy on a central visual field may present as a cluster of paracentral points with decreased sensitivity. These points may be only mildly depressed. 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.

Nov 18, 2011 To analyze Humphrey visual field HVF findings in hydroxychloroquine HCQ retinal tests were interpreted retrospectively in this observational case series of 15 patients with HCQ toxicity. Patients seen at Lahey Clinic were identified by. 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. 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.
