Chronic use of chloroquine and hydroxychloroquine in the treatment of rheumatic disease carries a small risk of sight-threatening pigmentary retinopathy. To obtain safety data for its use in pregnancy, we did ophthalmic examinations in 21 children born to women who took these drugs during pregnancy. Average daily maternal doses of the two drugs were 317 mg hydroxychloroquine and 332 mg chloroquine. The mean duration of gestational exposure was 7.2 months. No ophthalmic abnormality was detected in these children. Therapeutic use of these drugs during pregnancy may not pose a significant risk of ocular toxicity to offspring.
