PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of performing wide-angle and highly accurate OCT measurement using a concave mirror, and a control method thereof. An ophthalmologic apparatus includes an acquisition unit and a control unit. The acquisition unit includes a concave mirror and an optical scanner that deflects the measurement light and guides the measurement light to the reflection surface of the concave mirror. The acquisition unit uses the optical coherence tomography based on the measurement light reflected by the reflecting surface of the concave mirror to perform the A scan on the eye to be inspected located at the eye position or the conjugate position thereof to obtain the data of the eye to be inspected. get. The control unit causes the acquisition unit to perform the A scan according to the deflection operation state of the optical scanner. [Selection diagram] Figure 1【課題】凹面鏡を用いてより広角で高精度なＯＣＴ計測が可能な眼科装置、及びその制御方法を提供する。【解決手段】眼科装置は、取得部と、制御部とを含む。取得部は、凹面鏡と、測定光を偏向して凹面鏡の反射面に導く光スキャナーとを含む。取得部は、凹面鏡の反射面により反射された測定光による光コヒーレンストモグラフィを用いて被検眼位置又はその共役位置に配置された被検眼に対してＡスキャンを実行することにより被検眼のデータを取得する。制御部は、光スキャナーの偏向動作状態に応じて取得部にＡスキャンを実行させる。【選択図】図１
