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. Chloroquine show up on a drug test Can you take plaquenil with alcohol Oct appearance of plaquenil toxicity Plaquenil toxicity symptoms Etinopathy were monitored for 6 months to 82 months after HCQ cessation with multimodal imaging including spectral domain optical coherence tomography and fundus autofluorescence imaging at 488 nm standard and 787 nm near-infrared autofluorescence. Tests of visual function including visual acuity, Humphrey visual field testing, and multifocal electroretinography mfERG were performed. Jun 11, 2009 The talc deposits range from 5 to 10 µm in size and are visualized as refractile yellow opacities in the macula. Ischemic sequelae include peripheral retinal or optic disk neovascularization, vitreous hemorrhage and arteriovenous anastomosis. Patients often present complaining of severe, progressive vision loss. Chloroquine and hydroxychloroquine bind to melanin in the retinal pigment epithelium RPE and cause damage to the macular cones outside of the fovea. The drugs inhibit RPE lysosome activity, reduce phagocytosis of shed photoreceptor outer segments causing an accumulation of outer receptor segments.

Patients suspected of developing retinal toxicity should discontinue chloroquine therapy if possible and undergo further evaluation to confirm toxicity. Take-home points. Patients started on chloroquine or hydroxychloroquine for systemic inflammation are at low but real risk of retinal toxicity from these medications. Retinal toxicity from chloroquine CQ and its analogue, hydroxychloroquine HCQ, has been recognized for many years. The first reports concerned long-term use of CQ for malaria, and later reports showed retinopathy after treatment of anti-inflammatory diseases.1, 2 Chloroquine toxicity remains a problem in many parts of the world, but it is seen infrequently in the United States, where the. Conversely, in both normal adults and patients, we found many thickened structures that were undetect- able in visible wavelength light. To improve imaging of sub-retinal structures, we used infrared light, which passed readily into and out of the deeper fundus layers, with little visual consequence or pupil constriction Wyszecki & Stiles, 1982b.
