PROBLEM TO BE SOLVED: To make it possible to perform realignment operation even if an optical alignment index image disappears.SOLUTION: An ophthalmologic apparatus comprises: an optical head which includes an anterior ocular observation optical system for acquiring an anterior ocular segment image of a subject's eye, and fundus observation optical system for acquiring an optical index image of an alignment index projected onto the subject's eye and a fundus image of the subject's eye; display means for displaying an anterior ocular segment image and a fundus image in a switching manner; and alignment detection means for detecting the amount of misalignment between the subject's eye and the optical head, on the basis of the anterior ocular segment image. The ophthalmologic apparatus further comprises display control means for displaying, in areas outside the display area of the fundus image on the display means, electronic index images as many as the number indicated by the result of comparison between the detected amount of misalignment and a plurality of misalignment allowable amounts preset with respect to amounts of horizontal and vertical deviations.SELECTED DRAWING: Figure 1 |
