    摘要： An ophthalmic apparatus includes a light source, an iris aperture, a condensing member, a slit, and an image sensor. The light source is positioned substantially conjugate optically to an iris of an eye to be examined. The iris aperture is positioned substantially conjugate optically to the light source. In the iris aperture, an aperture is formed at an eccentric position from an optical axis. Illumination light from the light source passes through the aperture. The condensing member is positioned between the light source and the iris aperture. A slit is positioned substantially conjugate optically to a fundus of the eye to be examined. In the slit, a slit-shaped aperture is formed. The illumination light having passed through the aperture passes through the slit-shaped aperture. The image sensor is configured to receive returning light from the fundus illuminated by the illumination light having passed through the slit.

    摘要： An ophthalmologic apparatus includes a main body including a measurement optical system that measures eye characteristics of a subject eye; an anterior ocular segment camera provided in the main body to acquire an anterior ocular segment image by imaging an anterior ocular segment; and a controller that includes an alignment controller configured to control to adjust a relative positional relationship between the subject eye and the main body based on the anterior ocular segment image. The alignment controller includes an imaging start mode controller that is configured, when it is determined that the subject eye does not appear in the anterior ocular segment image in an imaging start mode by the anterior ocular segment camera, to calculate a predicted position of the subject eye based on image recognition of a face part in the anterior ocular segment image and to control movement toward the calculated predicted position.

    摘要： A slit lamp microscope of some embodiment examples includes an illumination system, first photographing system, first movement mechanism, and controller. The illumination system includes a slit forming unit that forms a slit for generating slit light and projects the 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 first movement mechanism moves a movable portion that includes at least the slit forming unit. The controller performs a first control for the first movement mechanism to move the movable portion and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other.

    摘要： The object of the present invention is to develop an ophthalmologic microscope of a new method that increases the degree of freedom in the optical design in the Galilean ophthalmologic microscope provided with an OCT optical system. The present invention provides an ophthalmologic microscope, wherein an observation optical system, an objective lens, and an OCT optical system are placed in such a way that the optical axis of the OCT optical system does not penetrate through objective lens, and the optical axis of the observation optical system and the optical axis of the OCT optical system are non-coaxial, and wherein the ophthalmologic microscope further comprises a SLO optical system that scans a light ray which is a visible ray, a near infrared ray, or an infrared ray and guides the light to the subject's eye so as to become substantially coaxial with the optical axis of the OCT optical system.
