Abstract
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.
摘要
在轻度视神经病变（Snellen视力正常）中，对低空间频率的对比敏感度降低，阈值测定的离散度增加。对不饱和颜色的感知也会降低。仅对小方格的图形视觉诱发电位显示中央凹神经通道的丧失。
