PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of accurately measuring a plurality of sites in an eye to be examining without changing a working distance.SOLUTION: An ophthalmologic apparatus includes an objective lens, an OCT optical system, an image forming part, and a control part. The OCT optical system that includes an optical scanner divides a light from a light source into a measurement light and a reference light, projects the measurement light deflected by the optical scanner onto the eye to be examined through the objective lens, and detects an interference light between a return light of the measurement light from the eye to be examined and the reference light. The image forming part forms a tomographic image of the eye to be examined on the basis of a result of the detection of the interference light. The control part controls at least the OCT optical system. The OCT optical system includes a plurality of lenses having mutually different refractive powers, which are selectively arranged between the objective lens and the optical scanner according to imaging sites, and a focusing lens arranged between the objective lens and the optical scanner, and moved in an optical axis direction in response to a change in the imaging site.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】作動距離を変更することなく被検眼における複数の部位を高精度に計測することが可能な眼科装置を提供する。【解決手段】眼科装置は、対物レンズと、ＯＣＴ光学系と、画像形成部と、制御部とを含む。ＯＣＴ光学系は、光スキャナーを含み、光源からの光を測定光と参照光とに分割し、光スキャナーにより偏向された測定光を対物レンズを介して被検眼に投射し、被検眼からの測定光の戻り光と参照光との干渉光を検出する。画像形成部は、干渉光の検出結果に基づいて被検眼の断層像を形成する。制御部は、少なくともＯＣＴ光学系を制御する。ＯＣＴ光学系は、互いに異なる屈折力を有し、撮影部位に応じて対物レンズと光スキャナーとの間に選択的に配置される複数のレンズと、対物レンズと光スキャナーとの間に配置され、撮影部位の変更に対応して光軸方向に移動される合焦レンズと、を含む。【選択図】図１
