PROBLEM TO BE SOLVED: To provide a technique capable of easily performing observation of a rear eye part of an eye to be examined accurately in a wide visual field.SOLUTION: An ophthalmologic apparatus of an embodiment comprises: an optical unit comprising a scanning optical system which deflects a light output from a light source in a prescribed deflection angle range, and can radiate a light from the light source and deflected by the scanning optical system to a rear eye part of the eye to be examined a movement mechanism for moving the optical unit in a prescribed movement angle range with a pupil position of the eye to be examined or the vicinity thereof as a reference position and a control part for controlling the scanning optical system so as to deflect the light from the light source based on the deflection pattern in each sub scan area of plural sub scan areas obtained by dividing a scan area, and controlling the movement mechanism so as to move between the sub scan areas based on a movement pattern.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】広い視野で高精度な被検眼の後眼部の観察を簡便に行うための技術を提供する。【解決手段】実施形態に係る眼科装置は、光源からの光を所定の偏向角度範囲内で偏向する走査光学系を含み、走査光学系により偏向された光源からの光を被検眼の後眼部に照射可能に構成された光学ユニットと、被検眼の瞳位置またはその近傍位置を基準に光学ユニットを所定の移動角度範囲内で移動させる移動機構と、スキャン領域を分割することにより得られた複数のサブスキャン領域の各サブスキャン領域内で偏向パターンに基づいて光源からの光を偏向するように走査光学系を制御し、移動パターンに基づいてサブスキャン領域間を移動するように移動機構を制御する制御部と、を含む。【選択図】図1
