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