    Nov 01, 2015 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.

The patient had been taking 400 mg of hydroxychloroquine daily for 10 years for the management of systemic lupus. On examination, a telltale sign of hydroxychloroquine toxicity is a bilateral change in the retinal pigment epithelium of the macula that gives the commonly described appearance of a bull’s-eye. This is a late finding, however, and too late for screening to be useful.

    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.

    Hydroxychloroquine HCQ is the anchor drug for the treatment of systematic lupus erythematosus SLE and is prescribed for the majority of patients 1. Its primary toxicity is retinal damage, because HCQ binds to and accumulates in the retinal pigment epithelium melanin 2. Combining the results of examinations, HCQ retinal toxicity was deter-mined by 1 ophthalmologist, an expert in retinal diseases. The pattern of retinal toxicity was described as a parafoveal pattern, pericentral pattern, or mixed pattern of retinal toxicity, according to the location of retinal damage. Hydroxychloroquine has significantly less retinal toxicity and has largely replaced chloroquine as a treatment of inflammatory disease. Unfortunately, the retinal damage from these medications is largely irreversible, so it is critical to detect early retinal toxicity in the hopes of limiting the extent of visual loss.
