The evaluation of the individual contrast sensitivity function may prove useful in cases affected by lesions of the optic pathways, even when the usual neuro-ophthalmological tests (i.e. visual acuity, visual field examination) are normal. The contrast sensitivity function represents an alternative method to assess the power of spatial resolution of the visual system: in particular, it enables to measure the sensitivity at high, medium and low ranges of spatial frequencies, this being unique to such a procedure. The possible physiological mechanisms underlying the contrast sensitivity function as well as its pathological changes are reviewed.
即使常规神经眼科检查（即视力、视野检查）正常，对视神经通路病变患者进行个体对比敏感度函数评估可能仍有用处。对比敏感度函数是评估视觉系统空间分辨能力的另一种方法：特别是，它能够测量高、中、低空间频率范围的敏感度，这是该方法所独有的。本文综述了对比敏感度函数潜在的生理机制及其病理变化。
