title: Demyelinative chiamal lesions.
abstract: To clarify the clinical syndrome of demyelinative chiasmal involvement, six case histories were analyzed and the literature was reviewed. This entitity is characterized by especial predilection for women in the third to fifth decades; visual deficites of a chiasmal pattern that may be modest to marked, with a generallly good prognosis for functional recovery; and other signs and symptoms, not necessarily severe, of scattered lesions of the neuraxis. Neuroradiological studies, especially laminography of the sellar area and computerized tomography, must be employed to rule out a suprasellar mass lesion. The efficacy of systemic corticosteroid therapy is moot, but it seems reasonable to use such agents during acute stages, especially where vision is severely reduced on both sides.
