title: [Color changes in certain areas of the fundus].
abstract: 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.
