Changes in certain areas of the fundus are frequently accompanied by changes in the spectral distribution of the reflected light. In many diseases of the fundus, it is desirable to have an objective definition of the color of the fundus during a particular phase of the disease. An instrument designed by Carl Zeiss, Oberkochen, West Germany, provides a satisfactory solution to the problem of measuring color on the fundus. Transformational equations make it possible to convert the measurement parameters obtained by visual comparison into standardized color measurement values. The measurement error is slighter than necessary for clinical examinations. Incipient cataracts cause only a slight shift of the color co-ordinates.
眼底某些区域的变化常常伴随着反射光光谱分布的变化。在许多眼底疾病中，需要对疾病特定阶段的眼底颜色进行客观定义。由西德奥伯科亨的卡尔·蔡司公司设计的一种仪器，为测量眼底颜色的问题提供了令人满意的解决方案。变换方程使将通过视觉比较获得的测量参数转换为标准化颜色测量值成为可能。测量误差比临床检查所需的误差更小。初期白内障只会使颜色坐标发生轻微偏移。
