A recent study investigated accident rates of individuals suffering from advanced glaucoma. The study was conducted in Japan and showed that potential drivers should pass a visual test in order to drive to make sure their peripheral vision is adequate. The research was recently presented at the 116th Annual Meeting of the American Academy of Ophthalmology.

The study included two groups of 36 individuals being tested on a driving simulator. One of the groups had advanced glaucoma. According to the Glaucoma Research Foundation, glaucoma is a disease that damages the optic nerve and partially or severely restrict a person's peripheral vision. Glaucoma, however, does not affect a person's central vision or vision acuity and the affected person could therefore pass the only vision test required throughout many countries know as the visual acuity test.

The study showed that, in both groups, the most likely scenario of an accident occurring was when a child, car or object suddenly came into the drivers path. However, those with advanced glaucoma had more than twice the odds of a collision when compared to the normal vision group.

In addition to more stringent eye tests, motorists are encouraged to have their vehicles tuned up at a local auto body shop to ensure safety while on the road. Individuals should especially have brakes checked with the upcoming cold weather and adverse driving conditions.
