Chloroquine is now uncommonly used in favor of its derivative hydroxychloroquine. In the United States, hydroxychloroquine is most often used for its anti-inflammatory effects in rheumatology and dermatology. Where is chloroquine resistant malaria Itching from plaquenil Chloroquine 150 mg Hydroxychloroquine Maculopathy An Update on Screening and Diagnosis A brief guide for imaging SHIRI SHULMAN, MD. 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. Chloroquine and hydroxychloroquine can cause toxic retinopathy due to their binding of melanin in the retinal pigmented epithelium RPE as well as direct toxicity to retinal ganglion cells. Early findings include mottling of the RPE and blunted foveal reflex. As the retinopathy progresses, a bull's-eye maculopathy develops, as seen in these. Ocular findings of HCQ retinal toxicity as detected by various screening modalities. A female patient was diagnosed with HCQ retinal toxicity at the age of 53 years, having taken HCQ for 12 years at 400 mg/day. While early toxicity may be asymtomatic, patients with more advanced stage of toxicity may complain of color vision changes or paracentral scotomas. Its toxic effects on the retina are seen in the macula.

During this exam, patients should receive a fundus examination; visual fields and spectral-domain optical coherence tomography SD-OCT should be added if maculopathy is present. And before treatment is initiated with hydroxychloroquine, a complete ophthalmic examination should be performed to determine any baseline maculopathy. Ophthalmologists should also follow the most current screening guidelines established by the Academy, 1 recently revised in light of new findings. Symptoms and Signs. Symptoms. Background/Aims Hydroxychloroquine HCQ retinopathy may result in severe and irreversible vision loss, emphasising the importance of screening and early detection. The purpose of this study is to report the novel finding of early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop in the setting of normal Humphrey visual field HVF testing.
