Abstract: 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.
