[Acquired disorders of contrast sensitivity and color vision in mild optic neuropathies].
In mild optic neuropathies (with full Snellen visual acuity), contrast sensitivity to low spatial frequencies is reduced and the scatter of the threshold determination is increased. Perception of desaturated colors is also reduced. Pattern visual evoked potentials to small checks only reveal a loss of foveal neural channels.
