OCULAR COMPLICATIONS OF CHLOROQUINE THERAPY.
Ocular complications of long-term chloroquine therapy were observed in 18 of 45 patients so treated. This therapy was used in patients with rheumatoid arthritis, lupus erythematosus, sarcoidosis, discoid lupus and other chronic "collagen disease". Thirteen patients had reversible corneal opacifications, and seven had irreversible retinal changes, with visual loss and visual field defects. Pathological evidence of chloroquine retinopathy was obtained in one patient. Physicians are therefore warned to use this drug only after careful consideration. If it is used, repeated ocular examinations should include assessment of visual acuity, visual fields on a tangent screen and fundus examination through a dilated pupil.
