Unit for obtaining and displaying fundus image, comprising: a display; a means for obtaining fundus image, having an objective; a memory means for storing a plurality of fundus images concerning the same eye to be examined, obtained through said means for obtaining fundus image, where positional relations between an optical axis of an eyeball of said eye to be examined and an optical axis of said objective are different from each other; wherein the means for obtaining fundus image further comprises a base provided with a camera body so as to be free to move within predetermined bounds in horizontal direction such that said positional relations between the optical axis of the eyeball of said eye to be examined and the optical axis of said objective being changeable from such a state that both are corresponded with each other to such a state that the optical axis of said objective lens is shifted from the optical axis of said eye to be examined in horizontal right/left direction; an image playback portion for repeatedly displaying said plurality of fundus images in such a state the optical axis of said objective lens is shifted from the optical axis of said eyeball in horizontally right/left direction, stored in said memory means in order on said display for a time set on each said fundus image so as to produce a three-dimensional pseudo image; a CUP contour position designating means for designating a CUP contour position on said three-dimensional pseudo image that is displayed on said display; a position specifying means for specifying said CUP contour position designated on said three-dimensional pseudo image based upon a specific fundus image of said plurality of fundus images; a CUP contour computing means for computing a CUP contour based upon said specified CUP contour position; and a position displaying means for displaying said computed CUP contour on said specific fundus image, wherein said display time that is set on said specific fundus image is longer than one of the other fundus image. a display; a means for obtaining fundus image, having an objective; a memory means for storing a plurality of fundus images concerning the same eye to be examined, obtained through said means for obtaining fundus image, where positional relations between an optical axis of an eyeball of said eye to be examined and an optical axis of said objective are different from each other; said positional relations between the optical axis of the eyeball of said eye to be examined and the optical axis of said objective being changeable from such a state that both are corresponded with each other to such a state that the optical axis of said objective lens is shifted from the optical axis of said eye to be examined in horizontal right/left direction; an image playback portion for repeatedly displaying said plurality of fundus images in such a state the optical axis of said objective lens is shifted from the optical axis of said eyeball in horizontally right/left direction, stored in said memory means in order on said display for a time set on each said fundus image so as to produce a three-dimensional pseudo image; a CUP contour position designating means for designating a CUP contour position on said three-dimensional pseudo image that is displayed on said display; a position specifying means for specifying said CUP contour position designated on said three-dimensional pseudo image based upon a specific fundus image of said plurality of fundus images; a CUP contour computing means for computing a CUP contour based upon said specified CUP contour position; and a position displaying means for displaying said computed CUP contour on said specific fundus image, wherein said display time that is set on said specific fundus image is longer than one of the other fundus image.
