Abstract
Cancer-associated retinopathy (CAR) is a paraneoplastic syndrome most often associated with small-cell lung carcinoma (SCLC), and it has been reported in patients with other malignancies. Antibodies against recoverin, a 23-kDa protein, have been found in patients with CAR suggesting an autoimmune phenomenon. Herein is the first report of a patient with non-small-cell lung cancer (NSCLC) in whom anti-recoverin antibodies were detected in the serum. Steroid therapy, chemotherapy, and radiation therapy did not help the patient's vision. Progressive loss of vision in patients with lung cancer should, potentially, be tested for CAR.
