PURPOSE: One of the main agenda questions of the conference is to address the types of visual problems that make a difference to driving. The purpose of this presentation is to provide a comprehensive review of data from patient studies investigating the relationship between vision and driving performance.
METHODS: By reviewing the findings from studies from patients having central and/or peripheral vision loss due to diseases such as juvenile-onset and age-related macular degeneration, retinitis pigmentosa, homonymous hemianopsia, diabetic retinopathy and glaucoma, the specific roles of visual acuity losses, visual field impairments, contrast sensitivity reductions, and wavefront aberrations can be elucidated.
RESULTS: In organizing the review in a meta-analytic fashion, according to the visual criteria of visual acuity, visual fields, and contrast sensitivity, information will be provided as to how these data may assist in establishing empirically-based guidelines for driver‘s licensure. Studies of devices focused on compensation for these deficits, as well as for wavefront aberrations will be presented. Recent work has shown the positive effects of addressing higher-order wavefront aberrations on tasks of lower contrast and lower illumination, including dusk and nighttime driving.
CONCLUSION: A review of the findings from these studies provides for a greater understanding of the risks that may be associated with driving with visual impairment. |
