A comparison of sensitivities to chromatic and luminance stimuli has been carried out in patients with a past history of optic neuritis. Patients were selected with differing degrees of stable residual visual deficits, and with marked interocular differences in sensitivity. Threshold contrast sensitivity was measured to sinusoidal luminance gratings and to chromatic red/green and blue/yellow gratings, all with the same spatial frequency of 1 cycle per degree. A psychophysical criterion was used to ensure that detection of the chromatic grating was determined only by its colour differences. When the difference between the sensitivity to luminance and chromatic gratings was compared between the more and less severely affected eyes of each subject, it was found that, overall, chromatic sensitivity was more severely impaired than luminance sensitivity in the disorder. Sensitivities to the red/green and the blue/yellow stimuli were found to be affected equally.
对有视神经炎病史的患者进行了对颜色和亮度刺激的敏感性比较。选择了具有不同程度稳定残余视力缺陷且两眼敏感性存在明显差异的患者。测量了对正弦亮度光栅以及红色/绿色和蓝色/黄色颜色光栅的阈值对比敏感度，所有光栅的空间频率均为每度1周期。采用心理物理学标准以确保颜色光栅的检测仅由其颜色差异决定。当比较每个受试者受影响程度较重和较轻的眼睛对亮度和颜色光栅的敏感度差异时，发现总体而言，该疾病中颜色敏感度的受损程度比亮度敏感度更严重。发现对红色/绿色和蓝色/黄色刺激的敏感度受到同等影响。
