To describe and establish control data from controls for a simultaneous interocular brightness sense test in which the apparent brightness of two independently viewed light patches was compared.
Dichoptic viewing was achieved by dissociation of right and left eyes using a septum and cross-polarization. Brightness matches were obtained by using adjustments to the illumination of the left retina while the illumination of the right retina was kept constant. OBSERVERS: Ninety-one control observers (age range, 20 to 91 years) participated in the study to provide normal brightness-matching data.
Effects from ocular dominance, age, and long- and short-term adaptation were negligible, but the test was sensitive to anisocoria. Just noticeable differences in dichoptic brightness matching were proportional to retinal illuminance; this finding was consistent with the Weber-Fechner law.
The test is quick and simple to complete and appears to offer considerable scope for the assessment of visual function when differences in the functional integrity of the optic nerves of the right and left eyes are suspected.
描述并建立用于双眼同时亮度感知测试的对照数据，该测试比较了两个独立观察的光斑块的表观亮度。
通过使用隔板和交叉偏振分离右眼和左眼来实现双眼分视。通过调整左视网膜的照明同时保持右视网膜的照明恒定来获得亮度匹配。
91名对照观察者（年龄范围20至91岁）参与了该研究，以提供正常的亮度匹配数据。
眼优势、年龄以及长期和短期适应的影响可忽略不计，但该测试对不等瞳敏感。双眼亮度匹配中刚刚可察觉的差异与视网膜照度成正比；这一发现与韦伯-费希纳定律一致。
该测试完成快速且简单，当怀疑左右眼视神经功能完整性存在差异时，似乎为视觉功能评估提供了相当大的空间。
