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. Can you stop taking plaquenil Phototherapy and hydroxychloroquine combination Plaquenil, hydroxychloroquine HCQ, is an anti-malarial medication that has been proven to be useful in the treatment of patients with rheumatoid arthritis RA, systemic lupus erythematosus SLE and other inflammatory and autoimmune diseases. Plaquenil-induced toxic maculopathy was first described in 1967. Because the retinal damage from plaquenil is usually irreversible if present for a more prolonged period of time, it is important to detect the disease in its early stages. 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. 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.

Retinal Physician - Hydroxychloroquine Maculopathy An Update.. Bull's-eye maculopathy due to hydroxychloroquine toxicity. Expanded spectral domain-OCT findings in the early detection of.. 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. Methods Data from. If the maculopathy continues to progress, concentric zones of hyperpigmentation and depigmentation seen below can form, causing irreversible toxicity. Later disease findings include peripheral bone spicules, vasculature attenuation, and disc pallor can mimic retinitis pigmentosa1 Examples of other patients with Bull’s Eye Maculopathy Sep 12, 2014 These findings were suggestive of hydroxychloroquine retinopathy, and the patient was advised to discontinue hydroxychloroquine. At 6-month follow-up, the patient’s visual acuity remained 20/20.
