Abstract:

Context.— Crash risk in older drivers has been associated with visual acuity loss, but only weakly so, suggesting other factors contribute. The useful field of view is a measure that reflects decline in visual sensory function, slowed visual processing speed, and impaired visual attention skills.

Objective.— To identify whether measures of visual processing ability, including the useful field of view test, are associated with crash involvement by older drivers.

Design.— Prospective cohort study with 3 years of follow-up, 1990-1993.

Setting.— Ophthalmology clinic assessment of community-based sample.

Patients.— A total of 294 drivers aged 56 to 87 years at enrollment.

Main Outcome Measure.— Motor vehicle crash occurrence.

Results.— Older drivers with 40% or greater impairment in the useful field of view were 2.2 . . . [Full Text of this Article]
