| Outline of Final Research Achievements |
To assess motor vehicle collision (MVC) risk in patients with visual field impairment using a driving simulator, 27 glaucoma patients and 13 retinitis pigmentosa (RP) patients (total = 40, all with better-eye mean deviation (MD; Humphrey Field Analyzer 24-2 SITA-S) <-12 dB), underwent driving simulator (Honda Motor Co., Tokyo) testing with eye tracking (EMR-9, NAC Image Technology, Tokyo). We assessed MD and binocular Esterman visual field test (EVFT) scores in the patients.
The number of collisions in the simulator correlated with binocular EVFT score in all patients (RP: r=0.74, P=0.004, glaucoma: r=0.47, P=0.02), but with better-eye MD in RP patients only (RP: r=-0.64, P=0.02, glaucoma: r=-0.16, P=0.45). Binocular EVFT score can be used to assess MVC risk.
