The method of color measurements by visual comparison was first described in 1974, but the original method was not always adequate in documenting fundal changes in patients being treated with vasodilatators. In these cases the color coordinates reached the threshold of the measuring scale or went beyond it in the livid color area. A few years ago the color measuring instrument was supplied with a new filter system for this purpose and was necessary to move the left cornerpoint of the measuring scale far into the blue range. The instrument and the physical data are described, the standard color values x and y being found by transformational equations. The technical error was measured on a phantom eye. In a defined group of 100 normal eyes (=100 testing persons) the standard color values of the temporal and nasal papillary segments were measured. They are graphically demonstrated in the now widened x; y measuring scale. Clinical use and results will be described later.
通过视觉比较进行颜色测量的方法最早于1974年被描述，但原始方法在记录接受血管扩张剂治疗患者的眼底变化时并不总是足够的。在这些情况下，颜色坐标达到测量刻度的阈值或在青紫颜色区域超出该阈值。几年前，为此目的为颜色测量仪器配备了新的滤光系统，并且有必要将测量刻度的左角点移至蓝色范围的深处。描述了该仪器和物理数据，通过变换方程找到标准颜色值x和y。在模拟眼上测量了技术误差。在一组定义的100只正常眼睛（=100名测试人员）中测量了颞侧和鼻侧乳头节段的标准颜色值。它们在现在拓宽的x；y测量刻度中以图形方式展示。临床应用和结果将在后面描述。
