We performed visual contrast sensitivity testing with Regan's low-contrast letter charts on 30 patients with optic neuropathies and good Snellen visual acuity. Results of this testing were compared with color vision and the presence of an afferent pupillary defect. Regan's low-contrast letter charts were found to be 93% sensitive for detecting subtle optic neuropathies, with the apparent false-negative findings being readily explainable. Color vision testing was abnormal in only 49% of eyes with known optic neuropathies.
我们使用里根低对比度字母图表对30例视神经病变且Snellen视力良好的患者进行了视觉对比敏感度测试。将该测试结果与色觉及传入性瞳孔障碍情况进行了比较。发现里根低对比度字母图表检测细微视神经病变的敏感度为93%，明显的假阴性结果很容易解释。在已知患有视神经病变的眼睛中，只有49%的色觉测试异常。
