Spatial contrast sensitivity function appears to give the most general description available for the basic aspect of spatial visual performance. Classical measurement of visual acuity is unable to give us a fine appreciation of visual function. Visual acuity is only one aspect of the complex process of sight. We have tested contrast sensitivity to detect silent lesions of the visual pathway. In multiple sclerosis we have demonstrated a bilateral involvement in almost all cases. In primary open angle glaucoma contrast sensitivity is affected before perimetry data are able to show any defect. We have the same results in early stages of diabetic retinopathy. Contrast sensitivity testing shows great promise for detection of eye defect in drivers and industry workmen.
空间对比敏感度函数似乎能对空间视觉性能的基本方面给出最全面的描述。传统的视力测量无法让我们很好地评估视觉功能。视力只是复杂视觉过程的一个方面。我们已经测试了对比敏感度以检测视觉通路的隐匿性病变。在多发性硬化症中，我们几乎在所有病例中都证实有双侧受累。在原发性开角型青光眼中，在视野检查数据显示任何缺损之前，对比敏感度就已受到影响。在糖尿病视网膜病变的早期我们也得到了相同的结果。对比敏感度测试在检测司机和产业工人的眼部缺陷方面显示出巨大潜力。
