PROBLEM TO BE SOLVED: To perform examination without being influenced by a direction of a visual line of a subject.SOLUTION: A visual field acuity examination device includes: a laser projection part having a light source for emitting a light beam and a scanning mirror for scanning the light beam and generating an image light beam for examination, which projects the image light beam for examination onto the retina of a subject as an image for examination; a driving part for moving the laser projection part; a visual line direction detection part for detecting a direction of a visual line of the subject; and a control part for causing the driving part to move the laser projection part according to the visual line direction.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】被験者の視線の方向に影響されずに検査を行うことを目的としている。【解決手段】光線を出射する光源と、前記光線を走査して検査用画像光線を生成する走査ミラーと、を有し、前記検査用画像光線を検査用画像として被験者の網膜に投影するレーザ投影部と、前記レーザ投影部を移動させる駆動部と、前記被験者の視線方向を検出する視線方向検出部と、前記駆動部に、前記視線方向に応じて前記レーザ投影部を移動させる制御部と、を有する視野視力検査装置である。【選択図】図4
