PROBLEM TO BE SOLVED: To provide a visual field examination device capable of reducing a time required for visual field examination and acquiring an accurate examination value, its control method, and a visual field examination program.SOLUTION: There is provided a visual field examination device including: a first probability density function acquisition unit for executing a step (1) for acquiring a probability density function f (x1) for a result value x1 acquired by a first visual field examination； a stimulation threshold determination unit for executing a step (2) for setting a stimulation threshold t1 from a range of x1 so that probability density of the probability density function f (x1) is divided； an examination result acquisition unit for executing a step (3) for acquiring an examination result on whether or not a result of the t1 or more can be acquired in the first visual field examination； a second probability density function acquisition unit for executing a step (4) for acquiring a probability density function f (x2) obtained by subtracting the probability density of t1 or more, or of less than t1 in the probability density function f (x1)； and a determination unit for executing a step (5) for determining whether or not a standard deviation σ of the probability density function f (x2) has become a state in which it is less than a predetermined value. There is also provided a control method of the visual field examination device, and a visual field examination program.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】視野検査に要する時間を短縮でき且つ正確な検査値を得る、視野検査装置、その制御方法及び視野検査プログラムを提供する。【解決手段】１回目の視野検査にて得られる結果値ｘ１に対する確率密度関数ｆ（ｘ１）を得る工程（１）を行う第１の確率密度関数取得部と、確率密度関数ｆ（ｘ１）の確率密度が分かれるようにｘ１の範囲から刺激閾値ｔ１を設定する工程（２）を行う刺激閾値決定部と、１回目の視野検査にてｔ１以上の結果が得られるか否かの検査結果を得る工程（３）を行う検査結果取得部と、確率密度関数ｆ（ｘ１）にてｔ１以上又はｔ１未満の確率密度を減じてなる確率密度関数ｆ（ｘ２）を得る工程（４）を行う第２の確率密度関数取得部と、確率密度関数ｆ（ｘ２）の標準偏差σが所定値未満に収まる状態になったか否かを判定する工程（５）を行う判定部と、を有する視野検査装置、その制御方法及び視野検査プログラムを提供できる。【選択図】図１
