Outline of Final Research Achievements

To assess motor vehicle collision (MVC) risk in older drivers with visual field impairment, 107 patients (mean = 62.8, S.D. = 13.8) underwent driving simulator (DS) testing with eye tracking and the Humphrey Field Analyzer 24-2 SITA-S program (HFA 24-2). We calculated the integrated visual field (IVF) based on HFA 24-2 data. The concordance/discordance between MVCs in the DS and the IVF was determined by examining eye tracking data in a recording of the DS test.
In older patients with visual field impairment, severe visual field impairment in the better eye, and had less eye movement were at higher risk for MVC. Discordance between DS MVCs and the IVF increased with age. Older drivers aged >70 years should understand their risk of MVCs due to visual field impairment and other factors.

Academic Significance and Societal Importance of the Research Achievements

加齢に伴い、判断力、運動能力が低下していることに加えて、視野障害があり、加齢に伴い進行することにより、自動車事故のリスクがあがることが分かった。一方で、視線の動きの大きい視野障害患者の事故は少なく、安全運転の指導により、事故を減らすことができる可能性があることが分かった。
