PROBLEM TO BE SOLVED: To provide highly reliable eye characteristics information quickly even when an alignment state is unstable.SOLUTION: An ophthalmologic apparatus includes: light projecting means having a light source for projecting measuring light to an eye to be examined and a light projecting optical system light receiving means for causing a light receiving element to receive the light reflected from the eye to be examined based on the light projecting means through a predetermined optical system information acquiring means for acquiring eye information on the eye to be examined from the light receiving result of the light receiving element and alignment detecting means for detecting the alignment state of the eye to be examined and a light receiving optical system. The ophthalmologic apparatus continuously conducts the alignment detection by the alignment detecting means during the period from the start of the measurement to the end of the measurement, and is provided with control means for controlling at least one of the light projecting means, the light receiving means, and the information acquiring means on the basis of the detection result of the alignment detecting means acquired during the period from the start of the measurement to the end of the measurement.COPYRIGHT: (C)2014,JPO&INPIT【課題】 アライメント状態が不安定であっても信頼性の高い眼特性情報を速やかに提供できる。【解決手段】 被検眼に向けて測定光を投光するための光源と投光光学系を有する投光手段と、投光手段に基づく被検眼からの反射光を所定の光学系を介して受光素子に受光させる受光手段と、受光素子の受光結果から被検眼の眼情報を得るための情報取得手段と、被検眼と受光光学系とのアライメント状態を検出するアライメント検出手段と、を有し、測定開始から測定終了までの間にアライメント検出手段によるアライメント検出を継続的に行うとともに,測定開始から測定終了までの間に得られる前記アライメント検出手段の検出結果に基づいて、投光手段,受光手段,情報取得手段の少なくとも1つを制御する制御手段を備える。【選択図】 図10
