Bilateral optic disc edema or swelling is termed papilledema, and is caused by elevated intracranial pressure. Any etiology that causes increased intracranial pressure may produce papilledema. However, if one optic disc has been afflicted with a previous condition resulting in optic atrophy, this may prevent observable disc swelling in that eye. The clinical picture of unilateral papilledema in one eye, and optic atrophy in the fellow eye, is referred to as Foster Kennedy syndrome. Foster Kennedy syndrome is commonly attributed to subfrontal masses on the side of the optic atrophy, resulting in the clinical presentation described below. In cases where an intracranial lesion or subfrontal mass has been ruled out, a noncompressive cause or pseudo-Foster Kennedy syndrome may be present, and results from a nontumor etiology. We report herein on a case of pseudo-Foster Kennedy syndrome, where the papilledema in one eye was associated with uncontrolled hypertension, and where the optic pallor in the fellow eye, is secondary to non-arteritic anterior ischemic optic neuropathy (NAION).
