Earlier literature on the prevalence of cq or hcq retinopathy included few patients on long-term therapy and only recognized severe toxicity (bull’s-eye changes). these reports have been superseded now by a large study of 2361 patients who used hcq for more than 5 years and were evaluated with 10-2 visual fields or spectral-domain optical coherence tomography (sd oct) so that toxicity could be recognized before there were any visible signs on fundus examination. 2 the overall prevalence of toxicity in this study population was 7. 5%, although it varied greatly with the daily dose and duration of use. daily dose (more properly, daily use, as measured by actual pharmacy dispensing) was the most critical determinant of risk, and the risk was more closely correlated with real weight than ideal weight. very thin patients in particular are at increased risk when dose is calculated by ideal weight (as previously recommended). patients in this new study2 mostly had been prescribed routine dos
