Abstract

One of the most common symptoms of multiple sclerosis is visual loss. But the most previous reported cases are unilaterai visual loss due to optic neuritis or retrobulbar optic neuritis or visual field defect due to chiasmal or optic tract lesion. We report a 34 year old female patient who had developed sudden onset of blindenss because of optic chiasm and optic tract lesion. She also complained of involuntary right hand movement and mild left hemiparesis. On T2-weighted image of MRI we found abnormal high sigmal intensities on the optic chiasm, bilateral optic tract, internal capsule and periventricular white matter. Her total blindness has not recovered until the last follow nine months after the initial event.
