PROBLEM TO BE SOLVED: To provide an ophthalmological apparatus capable of smoothly and easily performing manual alignment of the device optical system with respect to a subject's eye in a conventional manner without causing increase in the costs and size of the apparatus.SOLUTION: An ophthalmological apparatus according to an embodiment includes an optical system for inspection, a display unit, a subject's eye position acquisition unit, and a control unit. The optical system for inspection includes a photographic optical system for photographing a fundus of a subject's eye. The subject's eye position acquisition unit acquires a three-dimensional position of the subject's eye. The control unit acquires information on a positional deviation of the optical system for inspection with respect to the subject's eye on the basis of the three-dimensional position, and displays an alignment index image on the screen of the display unit on a pseudo basis to perform alignment of the optical system for inspection with respect to the subject's eye, depending on the positional deviation information. The control unit further has a plurality of display modes for displaying the alignment index image in a different display manner, and displays the alignment index image in a display mode selected from among the plurality of display modes on the screen of the display unit on a pseudo basis.SELECTED DRAWING: Figure 3 |
