We describe a simple device used to compare the sense of brightness in the two eyes. An investigation of brightness-sense with this device in normal persons and patients with optic nerve disease, maculopathies, cataract, and factitious visual impairment shows that brightness testing can provide useful information supplementary and complementary to conventional clinical and laboratory investigations. Impairment of brightness-sense was a consistent finding among patients with optic neuropathies and, in some cases, brightness testing appeared to be more sensitive than other techniques in establishing the presence of disease. Brightness-sense was also used to monitor the course of the patient's illness. Abnormalities were also found among some patients with unilateral maculopathies, but significant intereye differences in brightness-sense were not encountered among normal persons or patients with cataracts. Patients with factitious visual loss gave variable responses, and the nature of their disorder could be identified by the inconsistency of their responses.
我们描述了一种用于比较双眼亮度感知的简单装置。使用该装置对正常人和患有视神经疾病、黄斑病变、白内障及人为视力障碍的患者进行亮度感知调查，结果显示亮度测试可为传统临床和实验室检查提供补充和互补的有用信息。在视神经病变患者中，亮度感知受损是一个一致的发现，并且在某些情况下，亮度测试在确定疾病存在方面似乎比其他技术更敏感。亮度感知还用于监测患者的病程。在一些单侧黄斑病变患者中也发现了异常，但在正常人和白内障患者中未发现双眼亮度感知的显著差异。人为视力丧失的患者给出了不同的反应，并且可以通过他们反应的不一致性来识别其疾病的性质。
