Seven subjects were studied to determine the reproducibility of color isopters utilizing a Tubingen perimeter with targets equated for radiant energy and separate for heterochromatic flicker luminance. Achromatic threshold recognition of targets for equal luminance gave smaller isopters with longer wavelengths (red). Color recognition thresholds, on the other hand, showed large blue, midzone red and green, and small yellow isopters. The target recognition and color recognition thresholds for equal energy targets gave smaller red isopters. The data support Traquair's contention that all color isopters would be equivalent if hue, saturation, and intensity were equated. Clinically, the detection of subtle peripheral and central field defects might reside in the use of appropriately selected equally bright-colored targets.
对7名受试者进行了研究，以确定使用图宾根视野计测量色等视线的可重复性，该视野计的目标在辐射能量方面相等，且在异色闪烁亮度方面相互独立。对于等亮度目标，无色阈值识别显示，波长较长（红色）的目标等视线较小。另一方面，颜色识别阈值显示，蓝色等视线大，中间区域的红色和绿色等视线中等，黄色等视线小。对于等能量目标，目标识别和颜色识别阈值显示红色等视线较小。这些数据支持了特拉夸尔的观点，即如果色调、饱和度和强度相等，所有色等视线将是等效的。临床上，细微的周边和中心视野缺损的检测可能在于使用适当选择的同等明亮颜色的目标。
