Neuro-ophthalmic complications of interleukin 2 therapy

We describe three patients who experienced several types of visual problems while receiving interleukin 2 therapy for melanoma or lymphoma. Their symptoms included diplopia, binocular negative scotomata, scintillating scotomata, and palinopsia. All symptoms eventually resolved following discontinuation of therapy. It appears that focal neurologic deficits that affect the visual system may complicate interleukin 2 administration.
