This is a relatively late change, and good screening can detect toxicity before any bull’s eye is visible. On the other hand, visible bull’s-eye retinopathy. Spectral-domain optical coherence tomography demonstrating advanced hydroxychloroquine retinopathy with parafoveal loss of the external limiting membrane, disruption of the outer ellipsoid zone, thinning of the outer nuclear layer and disruption to the underlying retinal pigment. Hydroxychloroquine, sold under the brand name Plaquenil (Sanofi-Aventis), is an antimalarial drug that has gained widespread use in treating various autoimmune diseases, including systemic lupus erythematosus and rheumatoid arthritis.
