Abstract: An ophthalmic system of an embodiment includes a slit lamp microscope and an information processing apparatus. The slit lamp microscope includes an image acquisition device that acquires a three dimensional image by photographing a subject's eye, and a first communication device that transmits the three dimensional image to the information processing apparatus. The information processing apparatus includes a second communication device that receives the three dimensional image transmitted by the first communication device, a display controller that displays a first image based on the three dimensional image on a display device, a partial region designation processor that designates a partial region of the first image, and a rendering processor that renders the three dimensional image based on the partial region to construct a second image. The display controller displays the second image on the display device.

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.
