Visual involvement in primary non-Hodgkin's lymphomas.

This paper reviews the modalities of involvement of the visual function in patients with primary non-Hodgkin's lymphomas. They include the lymphomatous uveitis, the invasion of the orbital cavities and cavernous sinuses, and the involvement of the optic nerves, chiasm and optic tracts by lymphomatous lesions. Two cases of primary non-Hodgkin's lymphomas with visual disturbances are reported and the different mechanisms of visual pathway damage and clinical troubles are discussed from a large review of the pertinent literature.
