DRIVER VISUAL LIMITATIONS DIAGNOSIS AND TREATMENT

The primary objectives of the study were to (1) review the role of vision in driving, (2) evaluate the reliability and validity of the Mark II - a prototype battery of eight driving-related vision tests, and (3) evaluate the relationship between poor performance on the Mark II and clinically diagnosed visual impairments. A total of 890 subjects were tested on the Mark II. The results suggested the most reliable tests are the tests for static acuity (under conditions of glare, normal illumination, and reduced illumination), dynamic visual acuity, and detection-acquisition-interpretation (a measure of visual search efficiency). Tests considered less reliable and in need of modifications were those designed to measure threshold for angular movement and movement in-depth, and angular extent of the visual field in the horizontal axis. Regression analyses using accident rate or frequency as criterion variables indicated that - depending on the age group - the multiple correlation between performance on the vision test battery and the criterion variable varied from .12 to .31. The relative contribution of the individual tests to the prediction of accident involvement varied as a function of the age group, the criterion variable and the light condition (day vs. night).
