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 for lpp Chikungunya disease and chloroquine treatment Recommandation surveillance ophtalmologique plaquenil Massive hydroxychloroquine overdose Hydroxychloroquine is in a class of drugs called antimalarials. It is used to prevent and treat acute attacks of malaria. It is also used to treat discoid or systemic lupus erythematosus and rheumatoid arthritis in patients whose symptoms have not improved with other treatments. The electroretinogram ERG. The global or full-field electroretinogram ERG is a mass electrical response of the retina to photic stimulation. The ERG is a test used worldwide to assess the status of the retina in eye diseases in human patients and in laboratory animals used as models of retinal disease. Aetna considers multi-focal ERG mfERG medically necessary for detecting chloroquine Aralen and hydroxychloroquine Plaquenil toxicity. Aetna considers multi-focal ERG experimental and investigational for all other indications including the following not an all-inclusive list Diagnosis/evaluation of glaucoma 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.

However, the summed amplitude of multifocal ERG can vary significantly among normal subjects. Therefore, topographic abnormalities via a three-dimensional distribution map are useful for the interpretation of multifocal ERG in diseased patients. Multifocal ERG in Practice -. Electroretinography - Medical Clinical Policy Bulletins Aetna. New Plaquenil Guidelines -. Roquine Plaquenil; Sanofi, and generic formulations. The effects of toxic medications can be detected and quantified using ERG. Which type of ERG to apply depends on the mechanism and site of retinal toxic-ity. Identifying retinal toxicity due to chloroquine or hydroxychloroquine is a pertinent application of mfERG. SIGNS OF TOXICITY Dr. Marmor said, “We also recommend use of objective tests such as spectral domain OCT, multifocal ERG and fundus autofluorescence.” He added that older time domain OCT units lack enough sensitivity for Plaquenil toxicity. Go by ideal, not real, weight. Dr. The electroretinogram ERG is a diagnostic test that measures the electrical activity generated by neural and non-neuronal cells in the retina in response to a light stimulus. The electrical response is a result of a retinal potential generated by light-induced changes in the flux of transretinal ions, primarily sodium and potassium. Most often, ERGs are obtained using electrodes embedded in.
