title: Cancer-associated retinopathy.
abstract: Antiretina antibodies have been found in the serum samples of four patients with cancer experiencing concomitant loss of vision (cancer-associated retinopathy [CAR] syndrome). These immunoglobulins bound an antigen from normal pooled retina having a molecular weight of 23,000 daltons, which we describe as the CAR antigen. No corresponding antibodies could be found in serum samples obtained from patients with cancer not experiencing vision loss, from patients having retinitis pigmentosa, or from normally sighted individuals who did not have cancer. The early detection of rising antibody titers against the CAR antigen could prove important in the identification of patients likely to suffer from CARs.
