[Psychophysical symptoms of demyelinating diseases of the optic nerve in multiple sclerosis].

Visual system channels were examined in 25 patients with multiple sclerosis. A new complex of symptoms was detected, reflecting the acute stage and the chronic demyelinizing process, which includes disorders of contrast, color, and spatial contrast sensitivity and stereoscopic vision. This can be useful in differential diagnosis of optic nerve diseases and evaluation of the visual system function in multiple sclerosis and prediction of the disease course.
