Contrast sensitivity, as far as tested with pattern-VEPs, and light-difference sensitivity, psychophysically tested with the Octopus in the visual field center, seem to reflect different visual functions, because they are disturbed to a different degree in discrete neuropathies: light-difference sensitivity may be within normal range and a careful numerical analysis is needed in order to find pathologic differences. With VEPs, on the other hand, it is easier to detect a loss of normal neural conduction.
就用图形视觉诱发电位（pattern-VEPs）所测试的对比敏感度而言，以及就用Octopus在视野中心进行心理物理学测试的光差异敏感度而言，它们似乎反映了不同的视觉功能，因为在不同的神经病变中它们受到干扰的程度不同：光差异敏感度可能在正常范围内，需要进行仔细的数值分析才能发现病理差异。另一方面，对于视觉诱发电位而言，检测正常神经传导的丧失更容易。
