Abstract
The present invention intends to provide a fundus camera which enables an examiner to easily place a position for presenting the fixation target at an intended position. The fundus camera comprises an observation optical system having an objective lens and a photographic element for photographing a fundus of an eye to be examined via the objective lens, the fundus being illuminated by illumination light for observation, a monitor on which an image of the photographed fundus is displayed, a fixation-target presenting optical system for presenting a fixation target via the objective lens so that the fixation target is visually identified by the eye, a fixation-target moving unit by which a position for presenting the fixation target is moved to a desired position, a first display control unit by which the position of the fixation target to be moved is superposed on the fundus image to be displayed on the monitor, and a second display control unit by which a guide index for moving the fixation target is displayed at a desired position on the monitor.
