PURPOSE: To describe further the clinical and immunological features of cutaneous melanoma-associated retinopathy, which is an infrequent form of paraneoplastic syndrome.
METHODS: We studied the salient clinical and immunological aspects of a 66-year-old man with metastatic cutaneous melanoma to lymph nodes of unknown primary site who developed melanoma-associated retinopathy.
RESULTS: There was gradual loss of vision in the left eye. Colour vision and night vision were not affected. Visual fields showed arcuate defects. A full-field electroretinogram demonstrated attenuation of the b-wave amplitude in the left eye. The a-wave was intact. Indirect immunofluorescence techniques showed that the antibody reactions took place mainly in the outer plexiform layer of the retina.
CONCLUSIONS: Bipolar cells seem to be the target in melanoma-associated retinopathy. Contrary to previous reports, night blindness may not be a universal finding.
