As a group, drivers with obstructive sleep apnea (OSA) have an increased risk for motor vehicle crashes, but determining individual crash risk is difficult. We tested the hypothesis that drivers with OSA have impaired visual attention, as indexed by reduced useful field of view (UFOV), a predictor of high-risk driving. Forty-one drivers with untreated OSA and 50 comparison drivers were assessed by UFOV. OSA drivers performed significantly worse than controls on all UFOV subtests and had reduced UFOV as indicated by a higher mean total UFOV score (p = 0.0017). However, only 4 OSA and 2 control drivers had values indicative of high crash risk (UFOV reduction >23%). Drivers with OSA have reduced UFOV compared to drivers without neurological or sleep disorders. However, as UFOV identifies few high-risk drivers, its role in assessing crash risk in an unselected population of drivers with OSA appears to be limited.
总体而言，患有阻塞性睡眠呼吸暂停（OSA）的驾驶员发生机动车碰撞事故的风险增加，但确定个体碰撞风险却很困难。我们检验了这样一个假设：患有OSA的驾驶员存在视觉注意力受损，这可通过有用视野（UFOV）缩小来衡量，而UFOV缩小是高风险驾驶的一个预测指标。通过UFOV对41名未经治疗的OSA驾驶员和50名对照驾驶员进行了评估。在所有UFOV子测试中，OSA驾驶员的表现明显比对照组差，并且平均总UFOV得分更高，这表明他们的UFOV缩小（p = 0.0017）。然而，只有4名OSA驾驶员和2名对照驾驶员的值表明存在高碰撞风险（UFOV缩小> 23%）。与没有神经或睡眠障碍的驾驶员相比，患有OSA的驾驶员UFOV缩小。然而，由于UFOV只能识别出少数高风险驾驶员，其在评估未经过筛选的OSA驾驶员群体碰撞风险中的作用似乎有限。
