Mass visual field screening in a driving population.

With the cooperation of the California Department of Motor Vehicles and Synemed, Inc., visual field screening tests were administered to 1,027 eyes of driver's license applicants using the Fieldmaster Model 101-PR automated perimeter. Approximately 5% of the eyes tested demonstrated significant visual field loss. These results indicate that mass visual field screening in a driving population is feasible and may become a valuable technique for early detection of eye disease in large populations. It may also be an important factor in traffic safety.
