PROBLEM TO BE SOLVED: To solve the problem that if an anterior eye part adaptor lens is attached, internal fixation is also focused on the anterior eye part in photographing the anterior eye part so that fixation is not possible in photographing the anterior eye part.SOLUTION: An ophthalmologic apparatus for acquiring a tomographic image of an eye to be examined based on interference light acquired by multiplexing return light from the eye to be examined to which measurement light is applied, and reference light corresponding to the measurement light includes: a measurement optical system for guiding the measurement light to the ocular fundus or the anterior eye part of the eye to be examined a fixation optical system that shares part of an optical path with the measurement optical system for guiding a fixation mark that urges fixation of the eye to be examined to the eye to be examined and focus position changing means at least arranged in an optical path that is not shared by the measurement optical system and the fixation optical system for making a focus position of the measurement light and a focus position of the fixation mark different.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】前眼部アダプターレンズを取付けると前眼部撮影時は内部固視も前眼部にフォーカスが合ってしまい、前眼部撮影時に固視は出来なかった。【解決手段】測定光を照射した被検眼からの戻り光と、測定光に対応する参照光とを合波して得られた干渉光に基づいて被検眼の断層画像を取得する眼科装置に対して、被検眼の眼底又は前眼部に測定光を導く測定光学系と、測定光学系と一部の光路を共用し、被検眼の固視を促す固視標を被検眼に導く固視光学系と、測定光学系と固視光学系とが共用しない光路に少なくとも配置されて、測定光の合焦位置と固視標の合焦位置とを異ならせる合焦位置変更手段と、を配する。【選択図】図2
