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.

Abstract 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. 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, paracentral reductions in amplitude, indicative of depressed retinal function, are the most specific waveform pattern for HCQ retinopathy Fig. 7. Dr. Corte provides a quick reference guide based on the AAO's updated screening guidelines for chloroquine and hydroxychloroquine Plaquenil retinopathy. As optometrists, it is important that we are aware of the possible ocular complications that can occur from the use of high risk medications. 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. Plaquenil testing optometry PowerPoint.

It can decrease the pain and swelling of arthritis. It may prevent joint damage and reduce the risk of long-term disability. Hydroxychloroquine is in a class of medications that was first used to prevent and treat malaria. Hydroxychloroquine Plaquenil. Quick Reference Screening for Chloroquine & Hydroxychloroquine.. Eye screening for patients taking hydroxychloroquine Plaquenil. Sep 23, 2015 Dr. Corte provides a quick reference guide based on the AAO's updated screening guidelines for chloroquine and hydroxychloroquine Plaquenil retinopathy. As optometrists, it is important that we are aware of the possible ocular complications that can occur from the use of high risk medications. Apr 15, 2018 Plaquenil is typically prescribed as 200mg or 400mg daily. Clinicians should use real weight rather than ideal weight when calculating dosage because ideal weight can cause an overdose in thin individuals. 1 The target dosage is usually less than or equal to 5mg/kg of real weight. She suffered from Sjogren syndrome and inflammatory arthritis and was currently treated with prednisone and methotrexate. She was previously treated with hydroxychloroquine Plaquenil 200mg bid 6.5mg/kg for 10 years, which was stopped one year prior to presentation.
