Summary:To provide a visual field inspection device which can reduce a burden on a user resulting from a visual field inspection and perform a more accurate visual field inspection.SOLUTION: A visual field inspection device 1 comprises: a display 13 which displays a visual target; a sight line detection unit 25 which detects the sight line of a user to output sight line information about a direction of the sight line; a visual recognition determination unit 40 which determines whether or not the user visually recognizes the visual target on the basis of position information of the visual target and the sight line information; and a visual field inspection unit 60 which inspects a visual field range on the basis of the output of the visual recognition determination unit 40 by sequentially displaying the visual target at a prescribed position on the display 13. The visual field inspection unit 60 includes a visual recognition detection feedback part 65 which performs feedback processing of notifying the user of the fact that it is detected that the user visually recognizes the visual target for the prescribed time when it is detected that the user visually recognizes the visual target currently displayed on the display 13 by the output of the visual recognition determination unit 40.SELECTED DRAWING: Figure 1 【課題】視野検査に伴うユーザーへの負担を軽減し、より正確な視野検査を行うことのできる視野検査装置を提供する。【解決手段】視野検査装置1は、視標を表示するためのディスプレイ13と、ユーザーの視線を検出して視線の方向に関する視線情報を出力する視線検出部25と、視標の位置情報と視線情報とに基づき、ユーザーが視標を視認しているか否かを判定する視認判定部40と、ディスプレイ13上の所定の位置に視標を順次表示し、視認判定部40の出力に基づき、視野範囲を検査する視野検査部60と、を備え、視野検査部60は、視認判定部40の出力によりディスプレイ13上に現在表示している視標をユーザーが視認していることを検知すると、検知したことをユーザーに対して所定の時間だけ知らせるフィードバック処理を行う視認検知フィードバック部65を備える。【選択図】図1
