title: An unusual junctional scotoma.
abstract: A 28-year-old woman presented with painful unilateral left visual loss, impaired color vision, left afferent pupillary defect, and normal ocular fundus. Although optic neuritis was first suspected, visual fields disclosed a junctional scotoma related to chiasmal demyelination, due to a probable multiple sclerosis.
