Patient Population: Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed after drug cessation. O hydroxychloroquine Generic plaquenil problems The estimated risk of hydroxychloroquine retinopathy in patients on chronic hydroxychloroquine therapy ranges from 0.4% to 8.0%. 1 Toxicity is thought to be dependent on cumulative total dose. 3 Additional factors that can precipitate early toxicity are concomitant renal disease and use of tamoxifen. 3 Figure 1.

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 most common side effect associated with its use is retinal toxicity. SD-OCT is an objective test for toxicity that complements 10-2 visual field testing. 10-2 visual testing is probably more sensitive, but is heir to interpretational difficulties and variability not so much a problem with SD-OCT. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.
