PROBLEM TO BE SOLVED: To improve examination efficiency by shortening an examination time by reducing loads on an examinee and an examiner in a visual field examination.

SOLUTION: A perimeter 1 is provided with a fixation state determination means 5 for individually determining a fixation state of an examinee in association with displayed individual optotypes. The fixation state determination means 5 individually determines the fixation state every time an optotype is presented. Thus, even when the fixation state is determined to be defective, re-examination or the like is performed on only a point where the optotype is presented. Thus, in comparison with a case in which the whole examination is retried from the start as a conventional way, burden on the examinee and the examiner is made lighter, an examination time is made shorter and the examination efficiency is improved.

【課題】視野検査において被検者や検査者の負担を軽くし、検査時間を短くして検査効率を上げる。
【解決手段】本発明に係る視野計1は、表示される個々の視標に関連づけて被検者の固視状態を個別に判定する固視状態判定手段5を備えており、該固視状態判定手段5は、視標が表示される度に 個別に 固視状態を判定するようになっている。したがって、固視状態の不良が判定されたとしても、その視標が呈示されたポイントにつき再検査等を行えば良いので、従来のように検査全体を最初からやり直す場合に比べて、被検者や検査者の負担は軽くて済み、検査時間も短くて済み、検査効率を上げることができる。
