PROBLEM TO BE SOLVED: To provide a space-saving ophthalmologic apparatus capable of measuring an intraocular distance of a subject's eye.SOLUTION: The ophthalmologic apparatus includes an interference optical system, an optical path splitting member, an optical member, a movement mechanism, and an intraocular distance calculation part. The interference optical system splits light from a light source into reference light and measurement light, applies the measurement light to a subject's eye, generates interference light of return light thereof and the reference light, and detects the generated interference light. The optical path splitting member guides the reference light to a first reference optical path and a second reference optical path. The optical member includes a plurality of optical function parts including one or more translucent parts and one or more light shielding parts. The movement mechanism moves the optical member so as to simultaneously dispose any of the plurality of optical function parts on the first reference optical path and the second reference optical path respectively. The intraocular distance calculation part calculates an intraocular distance of the subject's eye on the basis of detection data of the interference light acquired by the interference optical system.SELECTED DRAWING: Figure 2【課題】省スペースで被検眼の眼内距離を測定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、干渉光学系と、光路分割部材と、光学部材と、移動機構と、眼内距離算出部とを含む。干渉光学系は、光源からの光を参照光と測定光とに分割し、測定光を被検眼に照射し、その戻り光と参照光との干渉光を生成し、生成された干渉光を検出する。光路分割部材は、参照光を第１参照光路及び第２参照光路に導く。光学部材は、１以上の透光部及び１以上の遮光部を含む複数の光学機能部を備えている。移動機構は、第１参照光路及び第２参照光路のそれぞれに複数の光学機能部のいずれかを同時に配置させるように光学部材を移動する。眼内距離算出部は、干渉光学系により取得された干渉光の検出データに基づいて被検眼の眼内距離を求める。【選択図】図２
