Contrast sensitivity function (CSF) was measured in 85 normal subjects and in 23 patients with optic neuropathy, using a personal computer and video monitor system. CSF in normal controls showed an inverted U-shaped function against spatial frequency with a peak at about 4-6 cycles/degree. At higher spatial frequencies, contrast sensitivity decreased with increasing age. CSF in patients was compared with Snellen acuity, visual field examination, critical flicker fusion frequency (CFF) and pattern VEP (P-VEP). CSF and P-VEP were more sensitive than the others in detecting visual dysfunction in optic nerve disease. These results suggest that ranges of normal values should be established for each of several age groups, and that CSF is useful for evaluating visual dysfunction.
使用个人电脑和视频监控系统，对85名正常受试者和23名视神经病变患者进行了对比敏感度函数（CSF）测量。正常对照组的CSF显示出针对空间频率的倒U形函数，在约4 - 6周/度处有一个峰值。在较高空间频率下，对比敏感度随年龄增长而降低。将患者的CSF与斯内伦视力、视野检查、临界闪烁融合频率（CFF）和图形视觉诱发电位（P-VEP）进行了比较。在检测视神经疾病的视觉功能障碍方面，CSF和P-VEP比其他指标更敏感。这些结果表明，应为几个年龄组分别建立正常值范围，并且CSF可用于评估视觉功能障碍。
