What is a Visual Fields Test?

One test that is performed at during a comprehensive annual eye exam is the visual field test. This is a extremely important test because it tests the neurological function of your eye and visual system. After images are focused on the back of your eye, or retina, they are sent through the optic nerve as electrical impulses to the occipital lobe of the brain. The occipital lobe is located in the back of the head near the base of the skull.

If anything, such as a tumor or aneurysm, is affecting the optic nerve as it travels through the brain, it will show up on the visual field test as a blind spot. The visual field test will also pick up loss due to inflammation in the optic nerve from some conditions such as multiple sclerosis and damage to the optic nerve from high eye pressures in glaucoma. Typically all of these causes of visual field defects have a specific pattern of loss that lead your optometrist to the diagnosis of what may be affecting your optic nerve.
