• A case of progressive bilateral visual loss of abrupt onset and rapid course is described. Extensive neuroroentgenographic evaluation was normal, and the results of exploratory craniotomy were unremarkable, except for a slight ovality of the left optic nerve. A biopsy of the left optic nerve showed a glioblastoma, apparently originating in the anterior optic pathways.
