Paraneoplastic Retinopathy Associated with Andretinal Bipolar Cell Antibodies in Cutaneous Malignant Melanoma. Serial assessment of clinical visual function, electroretinography, and assays of anti-retinal antibodies. Electroretinography revealed no responses of the right eye and attenuated responses of the left eye, especially those recorded under scotopic conditions. Anti-bipolar antibodies were detected. Subsequent evaluation uncovered adenocarcinoma of the colon. Several months after resection of the tumor and chemotherapy, no evidence existed of cancer or anti-bipolar cell antibodies, and electroretinography responses were markedly improved.
The presence of anti-bipolar cell antibodies in a patient with retinal dysfunction is not specific of melanoma-associated retinopathy. Effective treatment of cancer may result in elimination of associated anti-retinal antibodies and improved retinal function.
