Abstract

【課題】ＯＣＴ画像の計測時に被検眼が信号光の走査の軌跡を追従することを防止する。 【解決手段】眼底観察装置１は、低コヒーレンス光Ｌ０を信号光ＬＳと参照光ＬＲとに分割し、被検眼Ｅを経由した信号光ＬＳと参照ミラー１７４を経由した参照光ＬＲから干渉光ＬＣを生成して検出し、その検出結果に基づいて眼底Ｅｆの断層画像を形成する。眼底観察装置１は、信号光ＬＳを走査する走査ユニット１４１と、固視標を呈示するＬＣＤ１４０及び光学系を備える。眼底観察装置１は、信号光ＬＳを走査しつつ固視標を呈示した状態で眼底Ｅｆの画像を取得し、この画像に基づいて固視の適否を判定する。それにより、被検眼Ｅの固視の確実化を図り、ＯＣＴ画像取得時に被検眼Ｅが信号光ＬＳの走査の軌跡を追従することを防止する。
