Many systemic medications may cause retinal toxicity. One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine Plaquenil, a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus. Nov 01, 2015 H ydroxychloroquine HCQ; Plaquenil, Sanofi, Bridgewater, NJ is an antimalarial agent that is also commonly used as a treatment for a variety of rheumatologic and dermatologic conditions, such as rheumatoid arthritis and systemic lupus erythematosus. The most common side effect associated with its use is retinal toxicity, which may be irreversible. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

Plaquenil toxicity monitored 24-2 or 10-2Plaquenil losing weight Aug 06, 2014 Previously described OCT findings in HCQ toxicity include loss of the external limiting membrane, disruption of the outer ellipsoid zone, parafoveal thinning of the outer nuclear layer and RPE damage. 6,7,10 Despite these various changes, numerous studies have supported the notion that relative “foveal resistance” is common in HCQ toxicity, as demonstrated by preservation of the subfoveal outer retinal layers, accounting for the intact central visual acuity that can be seen even in. Multimodal Imaging in Plaquenil Toxicity. Retinal Physician - Hydroxychloroquine Maculopathy An Update.. Protecting your eyesight when taking Plaquenil Lupus.. Time Domain OCT in Hydroxychloroquine Plaquenil Toxicity. Time domain OCT does not have the resolution that spectral domain OCT has, making detection of hydroxychloroquine maculopathy by this modality less sensitive. Nevertheless, time domain OCT machines are more widely available, making it important to be able to recognize toxicity with this test. Newer studies have preferred practice protocols be changed to using spectral-domain OCT technology as the main screening device for detection of early retinal changes in plaquenil toxicity. MEDICAL EYE EXAMINATION Jan 01, 2020 For individuals with significant risk factors daily dose of hydroxychloroquine sulfate greater than 5.0 mg/kg base of actual body weight, subnormal glomerular filtration, use of tamoxifen citrate or concurrent macular disease monitoring should include annual examinations which include BCVA, VF and SD-OCT.
