    Hydroxychloroquine sulfate HCQ, Plaquenil is an analogue of chloroquine CQ, an antimalarial agent, used for the treatment of systemic lupus erythematosus, rheumatoid arthritis and other autoimmune disorders. Its use has been associated with severe retinal toxicity, requiring a discontinuation of therapy. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress. It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Although the incidence of macular toxicity is infrequent with Plaquenil use at a dosage of 200mg or 400mg q.d. its visual impact can be devastating. 2,3 The associated classic retinal toxicity is described as a bull’s eye maculopathy ring of depigmented retinal pigment epithelium that spares the foveal area.

    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.

The most common side effect associated with its use is retinal toxicity, which may be irreversible. Several authors have questioned the utility of screening for hydroxychloroquine toxicity given the low yield, high cost, and the difficulty in diagnosing the condition early enough to prevent damage. 43–46 Nevertheless, toxicity does occur, and if retinal and functional changes are detected early, severe visual impairment can be averted. 47, 48 Use of static perimetry through the vertical meridian with a red test object may be the best method to detect an early paracentral scotoma. 49. Since retinal toxicity is usually irreversible, early detection of retinal toxicity and cessation of the offending agent is the best treatment. Corneal toxicity presents as an intraepithelial deposition of the drug into the cornea, which rarely affects vision 1.
