Abstract: An illumination system of the ophthalmological device of an exemplary embodiment projects illumination light that has been outputted from a light source onto an anterior eye part of an examined eye. An interference photography system photographs an interference pattern that is formed on the cornea by the illumination light. An anterior eye part photography system photographs the anterior eye part onto which the illumination light is being projected. A first optical path coupling element couples the optical path of the interference photography system and the optical path of the anterior eye part photography system. A control part aligns an observation interference image that is at least a portion of an interference image that has been acquired by the interference photography system and an anterior eye part image that has been acquired by the anterior eye part photography system and makes a display device display the aligned images. The control part also makes the display device display observation location information that indicates the location of the observation interference image on the anterior eye part image.

Abstract: This fundus imaging device includes two or more curved mirrors, an illumination optical system, an image sensor, and a control unit. The illumination optical system irradiates the fundus of an eye under examination with slit-shaped illumination light via the two or more curved mirrors, and illuminates the fundus while moving the illuminated region. The image sensor can be disposed at a fundus-conjugate position, which is substantially optically conjugate with the fundus, and receives return light from the eye under examination. The control unit controls at least the illumination optical system. The longitudinal direction of an image formed by the illumination light on the fundus is substantially parallel to a plane that includes two or more focal points of the two or more curved mirrors. The control unit controls the illumination optical system so that the abovementioned image moves in a direction intersecting the longitudinal direction on the fundus.
