Disclosed is an eyeground observation device enabling acquisition of an OCT image with a high accuracy even if the eye to be examined moves or blinks during scan. The eyeground observation device (1) has a function of forming a tomogram and a three-dimensional image of the eyeground (Ef) during scanning with a signal light (LS) and a function of forming a moving image (observation image K) of the eyeground (Ef) during OCT measurement. The eyeground observation device (1) comprises an x-correcting unit (231) and a y-correcting unit (232) both for correcting the position in the direction of the eyeground surface of the three-dimensional image on the basis of the observation image (K) and a z-correcting unit (233) for correcting the position in direction of the eyeground depth of the three-dimensional image on the basis of a tomogram (Gi) of the eyeground (Ef) formed from the result of detection of the interference light (LC) of separately-swept signal light (LS) and reference light (LR).
