Outline of Final Research Achievements

This study revealed that functional visual acuity (FVA) was significantly correlated with the results of the useful field of view measured by VFIT-EV（Visual Field with Inhibitory -Elderly Version）and the driving aptitude test ( Presented at the annual meeting of the Association for Research in Vision and Ophthalmology; ARVO in 2014, Asia ARVO in 2015, and the 68th annual congress of Japan Clinical Ophthalmology), and showed that the FVA test may be a promising method to screen the driving aptitude including visual, cognitive(the useful field of view) and motor (reaction time of the driving aptitude test) functions within a short measurement time.
