PROBLEM TO BE SOLVED: To appropriately perform eye fixation for an eye to be examined by appropriately presenting a fixation target.
SOLUTION: The ophthalmologic apparatus has a fixation target projecting optical system for projecting the fixation target, and performs the examination for the examined eye in the fixated state. The fixation target projecting optical system includes a fixation target display part for electrically displaying the fixation target image for fixating the examined eye an optical member having optical diffusing properties disposed in a light path on the front surface of the fixation target display part or between the fixation target display part and the examined eye for obscuring the borders between pixels of the fixation target image displayed in the fixation target display part and a projection optical system for projecting the fixation target image displayed in the fixation target display part on the fundus of the examined eye via the optical member by a prescribed magnification.
