To characterize structural changes of HCQ retinopathy with SD-OCT after drug cessation. Setting Private practice and academic institution. Patient Population Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed. Plaquenil Toxicity Plaquenil hydroxychloroquine is a medicine commonly used to treat patients with systemic lupus erythematosus and rheumatoid arthritis. After prolonged use, it can sometimes damage the macula and cause central vision loss. Plaquenil is manufactured in only a 200 mg tablet The typical dosage is either 200 or 400 mg per day 200 mg daily puts anyone under 68 pounds at risk1 400 mg of Plaquenil daily puts anyone under 135 pounds at a higher risk for toxicity Therefore, 200mg of Plaquenil daily is going to be a safe dosage for virtually all adults13 Additionally, another exception occurred while executing the custom error page for the first exception.

Early Plaquenil Toxicity Detected without Bull’s Eye Maculopathy. Time Domain OCT in Hydroxychloroquine Plaquenil Toxicity.. Several risk factors may increase the likelihood of retinal toxicity from Plaquenil such as, age of greater than 60 years, daily dose more than 6.5 mg/kg; use of the drug more than 5 years, obesity, preexisting retinal disease and, renal or liver failure. Our patient demonstrates the importance of using the new recommended screening tools for the detection of early hydroxychloroquine toxicity. 10-2 HVF, SD-OCT, autofluorescence, or mfERG might have detected the hydroxychloroquine retinal toxicity on the day of her presenting symptoms and possibly earlier, potentially limiting the amount of visual loss. In obvious toxicity, the nasal inner subfield showed more thinning than the temporal inner subfield at 12 months after drug cessation p = 0.018, 95 % CI −1 to −8 μm. Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur.
