    Pasadhika and Fishman evaluated the peripapillary retinal nerve fiber layer RNFL thickness and macular inner and outer retinal thickness using spectral domain optical coherence tomography SD-OCT in patients with long-term exposure to hydroxychloroquine or chloroquine. In obvious toxicity, the nasal inner subfield showed more thinning than the temporal inner subfield at 12 months after drug cessation p = 0.018, 95 % CI −1 to −8 μm. Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur. 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.

    Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Retrospective clinical data review by the Boston Image Reading Center.

    Although hydroxychloroquine retinal toxicity is thought to be rare, recent studies suggest it may have a higher prevalence than previously recognized.

Hydroxychloroquine Plaquenil; HCQ has been an important and effective drug for the treatment of lupus erythematosus and related autoimmune and inflammatory diseases for half a century, although its potential to cause retinal damage continues to raise concern among rheumatologists and ophthalmologists.
