Wood JM, Black AA, Dingle K, et al. - Researchers conducted this systematic review to determine the effect of a range of vision disorders and visual impairments, including but not limited to those that are most prevalent in the community, like cataract, age-related macular degeneration, glaucoma, diabetic retinopathy and hemianopic field loss, on motor vehicle crash (MVC) risk and on-road driving performance. The inclusion criteria for MVC risk (N = 36), on-road performance (N = 9), and both MVC risk and on-road performance (N = 3) were met by 48 studies. Less than half of these studies were deemed to be of ‘good' quality. Because of the small number of studies and frequently contradictory findings, it was impossible to draw firm conclusions for the majority of vision disorders. However, evidence from several ‘good' and ‘fair' quality studies suggested that binocular visual field impairment increased MVC risk. The impact of cataract, glaucoma, age-related macular degeneration, and homonymous field loss on MVC risk was mixed, and there was no evidence of increased MVC risk with mild VA impairment.
