We report 2 patients with sickle cell anemia who showed retrocquatorial localized red retinal lesions. In 1 patient these lesions were associated with closure of the retinal precapillary arteriole and capillary bed. In both patients these lesions receded during the course of therapy with a selective arteriolar vasodilator, nifedipine.These observations are discussed in relation to the possible pathogenesis of the retinopathy seen in patientswith sickle cell anemia.
