HCQ binds to melanin in the retinal pigment epithelium (RPE), and this binding may serve to contribute to or prolong toxic effects. Methods A retrospective case–control study was performed to identify eyes with HCQ retinopathy/toxicity at Cleveland Clinic. Nov 01, 2007 · Retinal Toxicities Caused by Systemic Medications but the drugs bind to melanin in the retinal pigment epithelium (RPE) and affect photoreceptor metabolism. There are two types of RD: rhegmatogenous and nonrhegmatogenous. Arch McNamara, Franco Recchia, Carl D. While most cases of toxicity have been reported for chloroquine, hydroxychloroquine has supplanted it as the more commonly used treatment agent for both RA and SLE. Hydroxychloroquine (HCQ) retinopathy is of concern because of the potential seriousness of visual loss and the medicolegal consequences of failure to detect toxicity.
