| 27 | Cohort (R) | n=294, aged 55+ | Formal | Age/crash frequency only | Driver crash risk: drivers with substantial visual field loss were 6 times more likely to have incurred 1 or more crashes. Other vision measures were poor predictors of crash risk |
| 28 | Case-control | n=1400, 2636, aged 70+ | Formal | Yes | Driver crash odds: visual acuity was not a significant predictor of accident risk |
| 29 | Cohort (P) | n=2739, aged 49+ | Formal | Yes | Driver crash risk: neither visual acuity nor ability to see contrast in the best eye were significantly associated |
| 30 | Case-control (review) | aged 55+ | Formal | Yes | Driver crash odds: useful field of view between 41%-60%, the injurious crash risk OR 16.5 (95% CI 5.8 to 47.3), glaucoma OR 3.6 (95% CI 1.0 to 12.6). Other vision measures were not significantly associated |
| 31 | Case-control | n=279 cases, aged 55+ | Formal | Yes | Driver crash risk: relative risk of being a crasher in the prior 5 years compared to non-crasher with cataract RR 2.48 (95% CI 1.00 to 6.14) |
| 26 | Case-control | n=177, 471, children | Reported abnormal vision | Yes | Pedestrian injury odds: the adjusted odds ratio for the risk of injury abnormal vision was OR 4.25 (95% CI 1.68 to 10.8) |
| 32 | Cohort (R) | n=1878, aged 65+ | Formal | Yes | Driver crash risk: visual field was the only vision variable associated with crash involvement OR 1.33 (conference abstract only available) |
| 33 | Case-control | n=107, adults | Informal | Yes | Driver crash odds: did not have significantly higher on-road accident rates |
