Abstract: An ophthalmic apparatus includes an illumination optical system including a slit in which a slit-shaped aperture is formed and an iris aperture in which two apertures are formed at positions away from an optical axis position, the iris aperture being arranged at a position substantially conjugate optically to an iris of a subject's eye between a light source and the slit, and configured to generate slit-shaped illumination light using light from the light source and to guide the illumination light to a fundus of the subject's eye; and an imaging optical system including an imaging aperture in which an aperture is formed, and configured to guide returning light of the illumination light to an image sensor, the returning light being guided from the fundus by pupil division and passing through the aperture formed in the imaging aperture. A width of the slit-shaped aperture, a distance between the two apertures, and a size of the aperture in the imaging aperture are set so that an overlap region of a light flux region of the illumination light and a light flux region of the returning light is located on a side of the fundus from a posterior surface of lens of the subject's eye within the eye of the subject eye.

Abstract: A medical system of an aspect example includes a portable data storage, first information processing equipment, and telecommunication equipment. Medical information is stored in the portable data storage. The medical information includes authentication information of a subject who has undergone a medical examination and examination data acquired from the subject by the medical examination. The first information processing equipment is connected to a telecommunication network. The telecommunication equipment is configured to transmit at least part of the medical information stored in the portable data storage that has been moved to an available area of the telecommunication network, to the first information processing equipment via the telecommunication network.
