Symptomatic retrochiasmatic lesions due to demyelinating disease are rare in multiple sclerosis. The most
common cause of visual disturbance in multiple sclerosis is optic neuritis which typically presents with pain around
the eye that worsens with movement, dyschromatopsia and monocular decreased visual acuity. We describe a
patient who presented with bilateral blurry vision who was found to have a left congruous homonymous sectoranopia
due to a right lateral geniculate nucleus demyelinating lesion.
