Abstract: Provided are a disease risk evaluation method, a disease risk evaluation system and a health information processing device, whereby it becomes possible to detect the latent onset tendency in a healthy stage in advance and to quantify the prospective disease risk of a disease of interest. Each of the disease risk evaluation method, the disease risk evaluation system and the health information processing device according to the present invention includes a plurality of steps, i.e., a step for classifying into a group in which the susceptibility to developing a specific disease is high and a group in which the susceptibility to developing the specific disease is low regardless of the degree of progression of the disease from a healthy stage until the onset of the disease, and a step for further classifying the degrees of the development of the disease in a group in which the incidence risk is determined as high. Each of the disease risk evaluation method, the disease risk evaluation system and the health information processing device is characterized by being achieved by changing the type of data to be used in a data-driven analysis in each of the steps.

Abstract: A slit lamp microscope of some embodiment examples includes an illumination system, photography system, and movement mechanism. The illumination system projects slit light onto an anterior segment of an eye. The photography system includes an optical system and image sensor. The optical system directs light coming from the anterior segment onto which the slit light is being projected. The image sensor includes a light detecting plane that receives the light directed by the optical system. The movement mechanism moves the illumination and photography systems. The subject plane along the optical axis of the illumination system, the optical system, and the light detecting plane satisfy the Scheimpflug condition. The photography system acquires a plurality of images of the anterior segment by performing repetitive photography in parallel with movement of the illumination and photography systems performed by the movement mechanism.

Abstract: A slit lamp microscope of an aspect example includes an illumination system, first photographing system, fixation system, movement mechanism, and controller. The illumination system projects slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The fixation system outputs fixation light for fixation of the subject's eye. The movement mechanism moves the illumination system and the first photographing system. the controller performs a first control for the movement mechanism to move at least the illumination system and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other while causing the fixation system to output the fixation light.
