Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Hydroxychloroquine HCQ is a commonly used drug for the treatment of systemic lupus erythematosus SLE. Renal involvement is common in SLE. We present a 25-year-old woman with lupus nephritis on peritoneal dialysis whose lupus was quite silent for almost three years, and secondary to HCQ she developed severe hypoglycaemic episodes, which were completely resolved after stopping HCQ.
