A fundus oculi observation device 1 splits a low-coherence light L0 into a signal light LS and a reference light LR, generates an interference light LC from the signal light LS propagated through an eye E and the reference light LR propagated through a reference mirror 174 to detect the interference light LC and, based on the result of the detection, forms a tomographic image of a fundus oculi Ef. The device 1 includes a scan unit 141 configured to scan with the signal light LS, and an LCD and optical system that present a fixation target. The device 1 acquires an image of the fundus oculi Ef in a state that scan a fixation target is presented while scanning with the signal light LS, and based on the image, determines whether fixation is proper or not.
