摘要:
PROBLEM TO BE SOLVED: To provide an ophthalmologic examination apparatus capable of detecting whether or not a predetermined examination region is correctly observed and to provide an examination method for operating the ophthalmologic examination apparatus.SOLUTION: An ophthalmologic examination apparatus comprises: an examination optical system including an anterior eye part observing optical system for observing an anterior eye part of a subject eye 2 an optical system moving mechanism 95 for rotationally moving the examination optical system a display part 110 for displaying an image of the anterior eye part of the subject eye 2 a position specification part 109 for accepting a specification of a region to be examined of the subject eye 2 a rotation angle calculating part 111 for calculating, as a rotation angle, an angle to be satisfied at examination time between an eye axis of the subject eye 2 and an optical axis of the anterior eye part observing optical system on the basis of the position information of the region to be examined and an ideal display position calculating part 131 for calculating an ideal display position of a specific spot of the image of the anterior eye part to be displayed on the display part 110 while the examination optical system is rotationally moved by the rotation angle from a reference position. In the ophthalmologic examination apparatus, the display part 110 is so configured as to be able to display both the image of the anterior eye part and the information based on the ideal display position at the same time, with the examination optical system rotationally move by the rotation angle.COPYRIGHT: (C)2014,JPO&INPIT【課題】予め設定された被検部位を正しく観察できているかどうかを検出可能な眼科用検査装置及びそのような検査方法を実現する。【解決手段】 被検眼2の前眼部を観察する前眼部観察光学系を含む検査光学系と、検査光学系を回転移動させる光学系移動機構95と、被検眼2の前眼部画像を表示する表示部110と、被検眼2の被検部位の位置の指定を受け付ける位置指定部109と、被検部位の位置情報に基づいて、検査時に満たすべき被検眼2の視軸と前眼部観察光学系の光軸の間の角度を回転角として算定する回転角算定部111と、基準位置から前記回転角だけ検査光学系を回転移動した状態で表示部110上に表示されるべき前眼部画像上の特定箇所の理想表示位置を算定する理想表示位置算定
