Purpose The safety of bioptic telescopes for driving remains controversial. The ring scotoma, an area to the telescope eye due to the telescope magnification, has been the main cause of concern. This study evaluates whether bioptic users can use the fellow eye to detect in hazards driving videos that fall in the ring scotoma area. Methods Twelve visually impaired bioptic users watched a series of driving hazard perception training videos and responded as soon as they detected a hazard while reading aloud letters presented on the screen. The letters were placed such that when reading them through the telescope the hazard fell in the ring scotoma area. Four conditions were tested: no bioptic and no reading, reading without bioptic, reading with a bioptic that did not occlude the fellow eye (non-occluding bioptic), and reading with a bioptic that partially-occluded the fellow eye. Eight normally sighted subjects performed the same task with the partially occluding bioptic detecting lateral hazards (blocked by the device scotoma) and vertical hazards (outside the scotoma) to further determine the cause-and-effect relationship between hazard detection and the fellow eye. Results There were significant differences in performance between conditions: 83% of hazards were detected with no reading task, dropping to 67% in the reading task with no bioptic, to 50% while reading with the non-occluding bioptic, and 34% while reading with the partially occluding bioptic. For normally sighted, detection of vertical hazards (53%) was significantly higher than lateral hazards (38%) with the partially occluding bioptic. Conclusions Detection of driving hazards is impaired by the addition of a secondary reading like task. Detection is further impaired when reading through a monocular telescope. The effect of the partially-occluding bioptic supports the role of the non-occluded fellow eye in compensating for the ring scotoma.

“…() found that hazard perception test scores declined with age in a sample of drivers aged between 65 and 84 years. Preece, Horswill, and Geffen () found that drivers with traumatic brain injuries were significantly slower at responding to hazards compared with a matched control group. Even individuals with mild traumatic brain injury have been found to be significantly worse at hazard perception than a matched sample of individuals with orthopaedic injuries (Preece, Horswill, & Geffen, ).…”

Improving Fitness to Drive: The Case for Hazard Perception Training

On one hand, individuals who are unfit to drive should not be allowed behind the wheel. On the other hand, being unable to drive can have significant negative consequences for some individuals, including an increased mortality risk. One potential solution to this dilemma is to use training interventions to improve fitness-to-drive. The problem is that, in general, post-licensing driver training and education has a disappointing track record in terms of improving road safety. However, one type of intervention that may have the potential to buck this trend is hazard perception training. Hazard perception, which is the driver's ability to anticipate dangerous situations on the road ahead, has been found to predict both crash risk and on-road driving performance, and can account for variance in both of these criteria that other key fitness-to-drive measures cannot. Crucially, there is evidence that hazard perception competence can be improved by brief computer-based interventions, even for driver groups who are more likely to face fitness-to-drive challenges, such as individuals aged over 65 years or adults with attention deficit hyperactivity disorder. This article puts the case for potentially using such interventions to help individuals with fitness-to-drive difficulties.

“…Any malfunction of physical or cognitive skills may reduce driving performance (Wiebo H. Brouwer & Withaar, 1997;Shenouda, Hendrickson, Davenport, Barber, & Bell, 2012;Webster, Rapport, Godlewski, & Abadee, 1994), slow reaction time (Stokx & Gaillard, 1986), reduce driving skill (Stokx & Gaillard, 1986), and increase crash risk. Research shows that many cognitive processes, which are necessary for driving, will be affected by concussion (Bottari, Lamothe, Gosselin, Gélinas, & Ptito, 2012;Preece, Horswill, & Geffen, 2010). Not only would concussion affect the driving performance, but it also may exacerbate concussion symptoms (Rose, Weber, Collen, & Heyer, 2015).…”

“…In the case of fit-to-drive assessment, no research has been done. Most existing research tests the driving ability and driving performance after a concussion (Bottari et al, 2012;Novack et al, 2006;Preece et al, 2010;Sivak et al, 1981;Stokx & Gaillard, 1986), or discusses possible residual impairments after a concussion recovery (Schneider & Gouvier, 2005). None directly assess if a patient is fit-to-drive.…”

Driving after a brain injury is controversial. Since diagnosing a concussion and tracking the healing trend is challenging, whether or not a patient is fit-to-drive after the injury is open to interpretation. The primary purpose of the present research was to investigate the effect of a concussion on teen drivers' hazard anticipation skill. Twenty-four participants were recruited for this study in two groups: the concussed teen driver group and the non-concussed teen driver group. They were asked to wear an eye-tracker and drive with a driving simulator. The drive included several scenarios with potential latent hazards. While driving, the participants were expected to scan the latent hazards with their eyes and fixate at the hazardous area. The results show significant differences (p < 0.05) in the hazard anticipation skills between the two groups on two primary aspects: 1). The concussed group showed more random eye movements while the non-concussed participants had more deliberate eye fixations with less distractions and saccadic jumping. 2) The concussed patients showed a significantly poorer performance in anticipating the potential hazards. In conclusion, results indicate concussions can affect the hazard prediction skills of the teens, which in turn makes the driving task riskier for this group of drivers.

Assessment of drivers' ability to anticipate traffic hazards after traumatic brain injury

Abstract: Individuals with TBI were slower to anticipate traffic hazards than age-matched uninjured controls. This finding signifies the need for hazard perception testing and training as part of driving rehabilitation after TBI.
