A prospective, population-based study of the role of visual impairment in motor vehicle crashes among older drivers: the SEE study.

摘要: PURPOSE: To determine the role of vision and visual attention factors in automobile crash involvement. METHODS: Drivers aged 65 to 84 years were identified during baseline interview (1993-1995) Salisbury Eye Evaluation (SEE) Study. Crash involvement through December 1997 was determined from Maryland State motor vehicle records. Vision tests at included distance acuity normal low luminance, contrast sensitivity, glare stereoacuity, fields. Visual evaluated with Useful Field View Test (UFOV; Awareness, Chicago, IL). Survival analysis used relative risk a as function demographic variables, miles driven, vision, attention. RESULTS: One hundred twenty (6.7%) 1801 drivers involved observation interval. Glare sensitivity binocular field loss significant predictors (P < 0.05). For those moderate or better (<3 letters for <20 points missed fields) increased reduced fields were, paradoxically, associated reduction risk, whereas poorer levels risk. Worse UFOV score CONCLUSIONS: loss, Acuity, stereoacuity not crashes. These results suggest that current screening drivers' licensure, based primarily on acuity, may miss important aspects impairment. Language: en
