Problem to be solved: to simplify the switching operation of the photographing mode between the fundus photographing mode and the anterior eye photographing mode, to reduce the burden of the examiner and to shorten the switching time.Light source for emitting lightAn optical divider for dividing light from a light source into measurement light and reference lightThere is a focusing portion for changing the focusing state of the measurement light to the eye to be examined.A measurement optical system for projecting measurement light onto an eye to be examinedA control unit for generating a tomographic image using interference signals based on interference light between the measurement light and reference light is provided.Control sectionShooting modeIt includes a mode switching section which switches between the fundus photographing mode for photographing the fundus and the preocular photographing mode for photographing the anterior segment.In focusIn the fundus photographing modeThe measurement light can be focused on the fundus of the eye to be examined with an abnormal refractive index within a predetermined rangeIn anterior eye mode,Focus state of the measurement lightIn the fundus photographing mode, the eyeball on the fundus of the eye having a predetermined far viewing side refractive index value within a predetermined range is brought into focus in the case where the measurement light is focused.Ophthalmic optical coherence tomography.Diagram【課題】眼底撮影モードと前眼撮影モードの間の撮影モードの切替操作を簡便化することで、検者の負担を軽減させるとともに切替時間を短縮する。【解決手段】光を射出する光源と、光源からの光を測定光と参照光に分割する光分割器と、被検眼に対する測定光の合焦状態を変更する合焦部を有し、測定光を被検眼に投影する測定光学系と、測定光と参照光との干渉光に基づく干渉信号を用いて断層画像を生成する制御部とを備え、制御部は、撮影モードを、眼底を撮影する眼底撮影モードと前眼部を撮影する前眼撮影モードとで切り替えるモード切替部を含み、合焦部は、眼底撮影モードにおいて、所定の範囲内の屈折異常値を有する被検眼の眼底に測定光を合焦可能であり、前眼撮影モードでは、測定光の合焦状態を、眼底撮影モードにおいて所定の範囲内の所定の遠視側屈折異常値を有する被検眼の眼底に測定光を合焦させる場合の合焦状態にする、眼科光干渉断層撮影装置。【選択図】図１
