PROBLEM TO BE SOLVED: To provide an effective measuring and diagnosis support to a medical doctor by measuring the artery-vein diameter ratio of a comparison eyeground image in the same measuring place of the same subject, while referring to a reference eyeground image given the place of measurement of the artery-vein diameter ratio as information. SOLUTION: Image data for two eyeground images of identical subject that is photographed by an interval, character and symbol data including a reference eyeground image ID, the measurement point coordinates of the artery-vein diameter ratio in the reference eyeground image, a comparison eyeground image ID, and patient information are input to a control section 406 through a data input section 403. On the basis of the measurement point coordinate in the reference eyeground image, a search reference point of the measurement point in the comparison eyeground image is set. Subsequently, the measurement point of the artery-vein diameter ratio in the comparison eyeground image is detected, and the artery-vein diameter ratios in all the artery-vein diameter ratio measurement points in the two eyeground images are obtained. Thereafter, changes with respect to passage of time for the artery-vein diameter ratios are obtained and displayed. |
