Changes in certain areas of the ocular fundus are frequently accompanied by changes in the spectral distribution of the reflected light. In many diseases of the ocular fundus, it is desirable to have an objective difinition 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 ocular fundus. Transformational equations make it possible to convert the measurement parameters obtained by visual comparison into standardized color measurment values. The measurement error is slighter than necessary for clinical examinations. The possible influence of the ocular lens's own color on the color co-ordinates measured on the fundus was examined. Measurement of fundus color in three suitable situations showed no differences in color coordinates on the fundus between aphakic eyes of younger patients and eyes containing lenses. Incipient cataracts cause only a slight shift of the color co-ordinates. More marked cataracts cannot lead to erroneous interpretation of the measurement results, since measurement with this method is no longer technically possible in such cases.
眼底某些区域的变化常常伴随着反射光光谱分布的改变。在许多眼底疾病中，需要在疾病的特定阶段对眼底颜色进行客观定义。由德国西部奥伯科亨的卡尔·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。变换方程使得将通过视觉比较获得的测量参数转换为标准化的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。研究了晶状体自身颜色对眼底测量颜色坐标的可能影响。在三种合适的情况下对眼底颜色进行测量，结果显示年轻患者的无晶状体眼与有晶状体眼的眼底颜色坐标没有差异。初期白内障只会导致颜色坐标略有偏移。更明显的白内障不会导致测量结果的错误解读，因为在这种情况下用这种方法进行测量在技术上已不再可行。
