PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of precisely measuring an intraocular distance on an eye to be examined.SOLUTION: An ophthalmologic apparatus comprises: an interference optical system； a target projection system； a control part； and an intraocular distance calculation part. The interference optical system divides a light emitted from a first light source into a reference light and a measurement light, radiates the measurement light to the eye to be examined, then generates an interference light of a return light of the measurement light and the reference light, and then detects the generated interference light. The target projection system selectively projects a first fixation target and a second fixation target in which a visual angle is narrower than that in the first fixation target, to the eye to be examined. The control part switches the first fixation target and the second fixation target. The intraocular distance calculation part determines an intraocular distance on the eye to be examined, based on detection data of the interference light by the interference optical system, in a state in which the second fixation target is presented on a position which is a far point of the eye to be examined.SELECTED DRAWING: Figure 7【課題】被検眼における眼内距離を高精度に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、視標投影系と、制御部と、眼内距離算出部とを含む。干渉光学系は、第１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。視標投影系は、第１固視標及び第１固視標より視角が狭い第２固視標を被検眼に選択的に投影する。制御部は、第１固視標及び第２固視標の切り替えを行う。眼内距離算出部は、被検眼の遠点に相当する位置に第２固視標が呈示された状態において干渉光学系による干渉光の検出データに基づいて被検眼における眼内距離を求める。【選択図】図７
