The sensitivity of the VISTECH chart in the detection of hidden visual loss is debated. We tried to evaluate the diagnostic value of the test by using different illumination levels. Twelve MS-patients with normal acuity but a pathological VEP were examined at 9 different illuminations. We did not identify more abnormalities among patients, using VISTECH test at other illumination levels than the one recommended by the manufacturer.
VISTECH视力表在检测隐匿性视力丧失方面的敏感性存在争议。我们试图通过使用不同的照明水平来评估该测试的诊断价值。对12名视力正常但视觉诱发电位（VEP）异常的多发性硬化症患者在9种不同照明条件下进行了检查。我们发现在其他照明水平下使用VISTECH测试时，与制造商推荐的照明水平相比，并未发现患者中有更多异常情况。
