简要总结
This study will evaluate a new approach to training people with visual field loss to scan when driving
详细描述
Homonymous visual field loss is the loss of vision on the same side in both eyes. The most common types are hemianopia (the loss of one half of the field of vision) and quadrantanopia (the loss of one quarter of the field of vision). Hemianopia and quadrantanopia may cause difficulties in seeing objects on the side of the field loss. People with these types of field loss can compensate by scanning (looking) toward the side of the field loss. However, sometimes they might not scan sufficiently well resulting in delayed responses to hazards when driving. The purpose of this research study is to evaluate a new approach, "reminder-cue scanning training", to training people with homonymous visual field loss to scan when driving.
Participants will receive reminder-cue scanning training in the driving simulator.Typically there will be three training sessions within about a 2-week period. In addition, participants will complete an evaluation in the driving simulator before and after the training.
