Lymphoma-associated retinopathy

Abstract

Objective: To describe the clinical, electrophysiologic, and serologic findings in a patient with retinal degeneration associated with Hodgkin's lymphoma.

Design: Case report with ancillary immunohistochemical studies.

Methods: A 24-year-old woman experienced night blindness and fundus abnormalities 1 week after initiation of chemotherapy for Hodgkin's lymphoma. Visual fields and full-field electroretinograms (ERGs) were monitored over a 10-year period. Serum antibodies were studied on Western blot reactions on a solubilized extract of bovine retina. Serum antibodies were also evaluated through indirect immunohistochemistry on rhesus monkey retina.

Results: Visual field and ERG amplitudes, initially abnormal, became reduced further over 10 years. Serum antibodies were identified that reacted to a retinal protein or proteins approximating 65 kd; these antibodies showed immunologic activity against photoreceptors.

Conclusions: A progressive paraneoplastic retinopathy can occur in association with Hodgkin's lymphoma. The pathogenesis of the retinal degeneration appears to be related to a serum antibody that is reacting to a retinal protein or proteins of approximately 65 kd.
