Researchers recently reported on early optical coherence tomography OCT abnormalities due to HCQ toxicity that may develop through normal visual field VF testing. 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. 1 By some estimates, more than 150,000 patients are on long-term therapy with this medication in America alone. 2 Retinal toxicity associated with HCQ use is. Novel Image Analysis Platform May Detect Early Signs of Retinal Toxicity Secondary to Hydroxychloroquine Use. Ellipsoid zone mapping, a new image visualization/analysis platform on optical coherence tomography, may be an effective screening tool to identify subtle retinal changes indicative of toxicity from hydroxychloroquine treatment, Cleveland Clinic research indicates.

As shown by this study and by Marmor and Melles, cases of early HCQ toxicity that display visual field changes attributable to HCQ toxicity in the setting of a ‘normal SD-OCT’ may in fact have early changes on SD-OCT as described in this report. We did not, however, observe any cases of HCQ retinopathy in which the visual field was normal.
