Ophthalmic surveillance was performed on patients in a multicenter clinical trial testing high-dose (1000 mg daily) hydroxychloroquine for advanced non–small cell lung cancer. The US Food & Drug Administration–recommended screening protocol included only visual acuity testing, dilated fundus examination, Amsler grid testing, and color vision testing. Plaquenil eye pain Hydroxychloroquine sulfate 200 mg Allergy to chloroquine which anti-malaria tablets should you take Cases of long-term use of plaquenil causing low-blood sugar Most cases of chloroquine retinopathy have developed when a higher than currently recommended 3 mg/kg/day using lean body weight dose was used. 21 A daily dose exceeding 250 mg with a total cumulative dose between 100 and 300 g is customarily needed to produce toxicity. 22 One study showed a 19% incidence of chloroquine retinopathy in. Chloroquine-induced keratopathy is limited to the corneal epithelium, where high concentrations of the drug are usually used. The retinopathy encountered with the prolonged use of chloroquine analogues is a much more serious clinical problem and can lead to irreversible damage to the retina and loss of vision. Megan B. Goodman, Ari Ziskind, Fundus auto fluorescence and spectral domain ocular coherence tomography in the early detection of chloroquine retinopathy, African Vision and Eye Health, 2015, 74, 1CrossRef; 19 Junyeop Lee, Joo Yong Lee, Hydroxychloroquine Retinopathy, Journal of Rheumatic Diseases, 2015, 22, 3, 140CrossRef Out of the 7 patients having exposure of at least 6 months, 2 developed retinal toxicity (at 11 and 17 months of exposure). In patients seen at Stanford, additional sensitive screening procedures were added at the discretion of the retinal physician: high-resolution spectral-domain optical coherence tomography (OCT), fundus autofluorescence (FAF) imaging, Humphrey visual field (HVF) testing, and multifocal electroretinography (mf ERG).

Early detection of hydroxychloroquine-induced retinopathy is known to prevent visual acuity loss and serious progression after the therapy is stopped, and these data suggest that screening should. The risk of hydroxychloroquine-mediated retinal toxicity is relatively low within the first 5–10 years of therapy when used at daily doses that do not exceed 5 mg/kg, typically 200–400 mg daily. 1 Risk is clearly a balance between daily dose and duration of use, but there are little data available on the degree to which highly elevated doses can accelerate toxicity.
