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. Generic plaquenil ingredients Hydroxychloroquine 200 mg acetaminophen 400 mg Today it is recommended that every single person on Plaquenil get a visual field 10-2 test, plus one of the three other highly sensitive screening tests the FAF fundus autofluorescence imaging, the SD-OCT spectral domain optical coherence, or the multifocal electroretinogram mfERG,” Thomas says. May 02, 2018 The AAO guidelines go on to recommend the use of the multifocal electroretinogram multifocal ERG or mfERG as a functional test that can provide objective corroboration for visual fields by documenting parafoveal or extramacular electroretinogram depression in early retinopathy. 1 It is worth noting that the American Academy of Rheumatology AAR also recommends multifocal ERG be used as an objective test during the retinal exam. 6 Multifocal ERG vision testing is a type of light induced. Dec 04, 2014 mfERG may be the most sensitive test for early HCQ retinopathy, and numerous studies have evaluated the use of mfERG in the screening of HCQ retinopathy.19,20 Unlike full-field ERG, mfERG can localize deficiencies to the central macula, thereby detecting the subtle changes characteristic of early HCQ retinopathy.21,22 Specifically. 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.

This has similar sensitivity to visual fields and can provide objective confirmation of suspected paracentral field loss. Hydroxychloroquine Plaquenil Toxicity and Recommendations.. Hydroxychloroquine retinopathy A review of imaging. How Do Ophthalmologists Look for Plaquenil Damage? - American.. Dec 15, 2004 Multifocal ERG testing can detect abnormal function in chloroquine retinopathy even when the full-field ERG appears normal and visible macular alterations are subtle. The mfERG of patients with retinopathy can be altered in many ways including generalized depression of the mfERG, loss of the central peak waveform, as well as a pericentral loss. To describe the changes revealed by multifocal electroretinography ERG in patients taking hydroxychloroquine. PATIENTS AND METHODS Six patients being treated for various inflammatory conditions with hydroxychloroquine for periods ranging from 8 months to 7 years were consecutively evaluated. Other ERG tests, such as the photopic negative response PhNR and pattern ERG PERG may be useful in assessing retinal ganglion cell function in diseases like glaucoma. The multifocal ERG is used to record separate responses for different retinal locations.
