title: [Spatial contrast sensitivity in the differential diagnosis of optic neuritis].
abstract: Contrast sensitivity was examined in patients with optic neurites of different etiology. Achromatic and chromatic (red-black, green-black, and blue-black) sinusoidal patterns were presented in succession against the black background at a frequency of 1-22 cycles/degree on the monitor of an IBM computer. Contrast sensitivity was found altered during exacerbation of optic neuritis on both involved and intact eyes, this indicating a possible involvement of the chiasmal region. The authors discuss a new approach to investigation of the mechanisms of impairment of the optic nerve in optic neuritis in the presence of disseminated sclerosis and neuritis of obscure etiology.
