An apparatus is provided capable of forming three-dimensional images of the fundus oculi. The image forming part (220) of the computational control unit (200) forms images of the surface of the fundus oculi (Ef) based on results of detecting the fundus oculi catoptric light from the illumination light produced by the fundus camera unit (1A), in addition to forming tomographic images of the fundus oculi (Ef) based on the results of detecting the interference light (LC) from the OCT unit (150). The controlling part (210) synchronizes the timing of detecting the fundus oculi catoptric light from the illumination light produced by the fundus camera unit (1A) with the timing of detecting the interference light (LC) from the OCT unit (150). The correction processing part (240) corrects the image positions of the tomographic images based on the results of detecting the interference light (LC) from the OCT unit (150) on the basis of two-dimensional images based on the results of detecting the fundus oculi catoptric light from the illumination light produced by the fundus camera unit (1A). The image processing part (230) forms three-dimensional images of the fundus oculi (Ef) based on tomographic images for which the image positions have been corrected.
