Purpose. To confirm that subjects with primary open-angle glaucoma (POAG) who avoid driving in high-risk situations are less likely to be involved in motor vehicle collisions (MVCs) than those who do not. Methods. This study evaluated 252 consecutive Japanese aged between 40 and 85 years with POAG. All participants were requested to answer a questionnaire on their driving habits, including self-restriction in driving at night, in rain, in fog, on freeways, and lane changing, and history of MVCs. Those who reported restricting their driving in one or more ways constituted the self-restriction group, and those who reported no self-restriction made up the no-restriction group. The prevalence of MVCs and the crash rate (number of MVCs/10,000 km driven) were compared between the two groups. The association between prevalence of MVCs and the number of driving self-restrictions was also evaluated. Results. The association between driving self-restriction and MVCs was observed among the male subjects, not among the female subjects. Among the male subjects, the prevalence of MVCs was significantly higher in the no-restriction group than in the self-restriction group (no-restriction group, 33/107 = 30.8%; self-restriction group, 9/66 = 13.6%, p = 0.01). The crash rate was also significantly higher in the no-restriction group (no-restriction group, 1.4 T 0.8; self-restriction group, 0.4 T 0.3, average T SE, p = 0.01). No restriction was significantly associated with MVCs (multivariable-adjusted odds ratios, 2.43 [95% confidence interval, 1.03 to 5.73]). The number of driving self-restrictions was also associated with MVCs (multivariable- adjusted odds ratios, 0.41 [95% confidence interval, 0.18 to 0.99], per one increment of self-restriction). Conclusions. Driving self-restriction may be associated with a reduced prevalence of MVCs in men with POAG.
