Malignant lymphocytic lymphoma rarely involves the eye. In two patients we found ocular signs and symptoms as the initial presentation of systemic disease. In the first patient periorbital swelling and ptosis of one year's duration ultimately proved to be the result of malignant lymphoma. After resolution of swelling and ptosis with chemotherapy, the patient returned with diffuse iris involvement and uveitis with a hypopyon. In the second patient an acute change of refractive error proved to be the result of a lymphomatous deposit in the choroid. In both instances common symptoms were the initial manifestations of a diffuse malignant disease.
