目的.双光望远镜（BTS）由一个小型望远镜（或多个望远镜）组成，安装在一对眼镜镜片的高处。超过40个州允许中央视力下降的人获得某种形式的生物驾驶执照。本研究的目的是确定以前的驾驶经验，视力和机动车碰撞（MVC）的bioptic司机在俄亥俄州之间的显着关联。我们对接受视力检查并随后获得活检许可的患者进行了回顾性研究。我们从俄亥俄州机动车管理局获得了驾驶记录，以确定MVC的参与。采用时间-事件分析和考克斯比例风险回归模型研究了视力指标、年龄、性别、既往经验和MVC之间的关系。我们确定了237个活检驱动程序（65%男性）。初次检查时的年龄范围为16至81岁，平均视力约为20/120。每个驾驶员的MVC数量从0到11不等，其中124名（52%）驾驶员至少有一个MVC。视力和对比敏感度不是MVC的显著预测因子。没有驾驶经验的驾驶员更有可能参与MVC（P < 0.001），在调整年龄和性别后，这种关联仍然显着（P = 0.01）。在10年的时间里，没有经验的司机每年的MVC率稳步下降。以前的非活检驾驶经验，但不是视力或对比敏感度，与每年的MVC率活检司机。
PURPOSE. Bioptic telescopic spectacles (BTS) consist of a small telescope (or telescopes) mounted high in a pair of spectacle lenses. More than 40 states allow for some form of bioptic driving licensure for people with decreased central vision. The purpose of this study was to determine significant associations among previous driving experience, vision, and motor vehicle collisions (MVCs) for bioptic drivers in Ohio.METHODS. We conducted a retrospective study of patients who received a vision examination and subsequently obtained bioptic licensure. We obtained driving records from the Ohio Bureau of Motor Vehicles in order to determine MVC involvement. Relationships among vision measures, age, sex, previous experience, and MVCs were investigated using time-to-event analysis and the Cox proportional hazards regression model.RESULTS. We identified 237 bioptic drivers (65% male). Age at initial exam ranged from 16 to 81 years, and mean visual acuity was approximately 20/120. The number of MVCs per driver ranged from 0 to 11, with 124 (52%) drivers having had at least one MVC. Visual acuity and contrast sensitivity were not significant predictors of MVC. Drivers without previous driving experience were significantly more likely to have been involved in an MVC (P < 0.001), and this association remained significant after adjusting for age and sex (P = 0.01). The rate of MVC per year decreased steadily over a 10-year period for drivers without previous experience.CONCLUSIONS. Previous nonbioptic driving experience, but not visual acuity or contrast sensitivity, was associated with yearly MVC rate in bioptic drivers.
