title: Long-term course of chloroquine retinopathy after cessation of medication.
abstract: Seven patients with chloroquine retinopathy were examined ten years after their therapy with chloroquine or hydroxychloroquine, or both, had been discontinued and an additional five patients with chloroquine retinopathy were similarly examined from two to eight years after their therapy had been discontinued. Visual acuity, visual fields, and ophthalmoscopic examinations were compared to those performed at the time therapy was discontinued. These long-term observations confirmed the previously published observations based on short-term studies that chloroquine retinopathy tends to remain stable after therapy is discontinued, although a few patients in the early stages of retinopathy may show regression and occasionally a patient with a more advanced stage of the disease may show progression.
