Outline of Final Research Achievements

Visual field test with gaze movements do not require a subjective response because they are based on reflexive movements. In this study, we developed a visual field test system with gaze movements to perform a central visual field screening, and then examined the reproducibility of the measurements in healthy adult volunteers. In the traditional method for measuring visual field with gaze movements, the fixation point of view needs to be reset for each gaze movement. On the other hand, the system developed in this study has the advantage of not requiring eye movements to return to the fixation point. The present findings indicate that our newly developed system is a useful device when standard perimetry is difficult to measure.

Academic Significance and Societal Importance of the Research Achievements

一般的な視野検査では中心点の注視と自覚的応答を必要とする。そのため,乳幼児や知的障害者,重度・重複障害者のように,検査の理解や自覚的応答を十分に得ることが難しい場合,視野の定量化が困難という問題がある。この問題を解決できる可能性のある視野検査法として視線追従に基づく視線視野計測法がある。今回,ディスプレイ型装置を用いて固視点へ復帰させるための眼球運動を必要としない光点探索課題によって視線移動を記録する視線視野計測装置と,計測結果を素早く定量化するための解析ソフトウェアから構成される視線視野計測システムを考按することができた。
