Aging-related changes of the kinetic visual field

Study of the kinetic visual field of humans and the effect of aging upon it is strongly needed in order to identify the cause of traffic accidents while focusing on these characteristics. In this paper, differences in the kinetic visual field between younger and older people were measured and analyzed after identifying problems with the conventional definition of the kinetic visual field and modifying the kinetic perimeter system. In addition, by measuring simple reaction time when the kinetic visual field is measured in order to minimize the effect of individual differences in response time, it was confirmed that older people are greatly affected by deteriorating visual performance caused by aging, particularly in upward visual field rather than downward visual fields in all target conditions. Visual field angle reductions in the temple sides of upward visual fields were of particular note.
