The purpose of this research is to make adjustments to the objective automatic perimetry method using saccadic eye movement, so that it can be applied to clinical situations. In this study, we have conducted four experiments using several variables and collected basic data necessary for applying the new perimetry method in clinical situations. As a result, the following four findings were obtained from experiments: (1) in some people, it might be difficult for saccadic eye movement to occur when the target duration is short; but (2) it is possible that saccadic eye movement will immediately occur towards the target position with the use of reinforcement; (3) it is possible that the use of cartoon figure as a fixation point in the perimetry would presumably allow field of vision measurement; and (4) it is possible to assess the field of vision without the use of a fixation point. The improved objective automatic perimetry system now has the potential for wider clinical application.
