PURPOSE
Bioptic telescopic spectacles can be used by people with central visual acuity that does not meet the state standards to obtain an unrestricted driver's license. The purpose of this study was to examine the relationships among visual and demographic factors, training hours, and the results of road testing for bioptic drivers.
METHODS
A retrospective study of patients who received an initial daylight bioptic examination at the Ohio State University and subsequently received a bioptic license was conducted. Data were collected on vision including visual acuity, contrast sensitivity, and visual field. Hours of driver training and results of Highway Patrol road testing were extracted from records. Relationships among vision, training hours, and road testing were analyzed.
RESULTS
Ninety-seven patients who completed a vision examination between 2004 and 2008 and received daylight licensure with bioptic telescopic spectacles were included. Results of the first Highway Patrol road test were available for 74 patients. The median (interquartile range) hours of training before road testing was 21 (17) hours (range, 9 to 75 hours). Candidates without previous licensure were younger (p < 0.001) and had more documented training (p < 0.001). Lack of previous licensure and more training were significantly associated with having failed a portion of the Highway Patrol test and points deducted on the road test.
CONCLUSIONS
New bioptic drivers without previous nonbioptic driving experience required more training and performed more poorly on road testing for licensure than those who had previous nonbioptic licensure. No visual factor was predictive of road testing results after adjustment for previous experience. The hours of training received remained predictive of road testing outcome even with adjustment for previous experience. These results suggest that previous experience and trainer assessments should be investigated as potential predictors of road safety in bioptic drivers in future studies.
目的
中心视力未达国家标准的人员可使用双目间接检眼镜获得无限制驾驶执照。本研究旨在探讨视觉和人口统计学因素、训练时长与双目间接检眼镜驾驶者路考结果之间的关系。
方法
对在俄亥俄州立大学接受初次日间双目间接检眼镜检查并随后获得双目间接检眼镜驾驶执照的患者进行回顾性研究。收集包括视力、对比敏感度和视野在内的视觉数据。从记录中提取驾驶员培训时长和公路巡逻队路考结果。分析视觉、训练时长和路考之间的关系。
结果
纳入了97例在2004年至2008年间完成视力检查并通过双目间接检眼镜获得日间驾驶执照的患者。74例患者有首次公路巡逻队路考结果。路考前训练的中位数（四分位间距）时长为21（17）小时（范围为9至75小时）。以前未取得过执照的考生更年轻（p < 0.001）且有更多记录在案的训练（p < 0.001）。以前未取得过执照和更多的训练与公路巡逻队部分考试不及格及路考扣分显著相关。
结论
与有过非双目间接检眼镜驾驶执照的人相比，没有非双目间接检眼镜驾驶经验的新双目间接检眼镜驾驶者需要更多训练，且在执照路考中的表现更差。在调整先前经验后，没有视觉因素能预测路考结果。即使调整了先前经验，所接受的训练时长仍能预测路考结果。这些结果表明，在未来研究中，应调查先前经验和培训师评估作为双目间接检眼镜驾驶者道路安全潜在预测因素的情况。
