A Prospective, Population-Based Study of the Role of Visual Impairment in Motor Vehicle Crashes among Older Drivers: The SEE Study
The purpose of this study was to determine the role of vision and visual attention factors in automobile crash involvement.
This was a prospective, population-based study conducted on 1801 drivers aged 65 to 84 years.
120 (6.7%) of the sample drivers were involved in a crash during the observation interval.
Glare sensitivity and binocular field loss were significant predictors of crash involvement (P < 0.05).
Participants with moderate or better vision increased glare sensitivity or reduced visual fields were, paradoxically, associated with a reduction in crash risk.
For participants with poorer levels of vision, increased glare sensitivity or reduced visual fields were associated with increased crash risk.
Worse UFOV score was associated with increased crash risk.
Glare sensitivity, visual field loss, and UFOV were significant predictors of crash involvement.
