Effects of Reaction Time on the Kinetic Visual Field
Kinetic visual field refers to the visual range in which a moving target can be seen. The reaction time in traditional Kinetic Perimetry was the time from the target was identified to the subject responded, without taking into account individual simple reaction time (SRT). This is problematic in that it mixes the evaluations of human visual performance with behavior performance. We redefined kinetic visual field by analyzed the components of the RT, and then measured SRT and kinetic visual field of six normal subjects, using a modified Goldman kinetic perimeter. The results showed that the newly defined kinetic visual field was wider than traditional defined, because the newly defined kinetic visual field without including SRT. Thus, Kinetic Perimetry using the newly defined method eliminates individual SRT differences to produce what we believe to be a more accurate evaluation indicator of human visual functions.
