A fundus observation device comprises: an image forming part comprising a first image forming part and a second image forming part, the first image forming part forming a 2-dimensional surface image of fundus oculi of an eye through optical processing, the second image forming part optically scanning a surface region of the fundus oculi corresponding to at least a part of the 2-dimensional surface image to form a tomographic image of the fundus oculi; a controller configured to control the image forming part; and a storage configured to store control information including control instructions to be sent from the controller to the image forming part, when one of the 2-dimensional surface image and the tomographic image is formed. The controller, at the time of formation of new one of the 2-dimensional surface image and the tomographic image of the fundus oculi, instructs the image forming part to form the new one of the 2-dimensional surface image and the tomographic image based on the control information stored in the storage.
