PROBLEM TO BE SOLVED: To provide a mechanism to reduce distortion and unevenness in brightness caused in a fixation target visually recognized by a subject.SOLUTION: An ophthalmologic apparatus includes a fixation lamp 101 for emitting a fixation light which is a light for fixing a subject's eye, a resonance scanner 108 for scanning the fixation light on the ocular fundus of the subject's eye by being reciprocatingly driven, detection means (a correction PD 114 and a scan state estimation part 210) for detecting information indicating a scan position of the scan based on the reciprocating drive of the resonance scanner 108, and a fixation lamp control part 230 for controlling the fixation light irradiated onto the subject's eye based on the information indicating the scan position detected by the detection means.SELECTED DRAWING: Figure 2【課題】被検者によって視認される固視標に生じる歪みや明るさのムラを低減する仕組みを提供する。【解決手段】被検眼を固視させるための光である固視光を発生させる固視灯１０１と、往復駆動することによって固視光を被検眼の眼底上において走査させる共振スキャナ１０８と、共振スキャナ１０８の往復駆動に基づく走査の走査位置を示す情報を検知する検知手段（補正ＰＤ１１４及び走査状態推定部２１０）と、検知手段で検知された走査位置を示す情報に基づいて、被検眼に照射される固視光を制御する固視灯制御部２３０を備える。【選択図】図２
