Visual Field Assessment

Many eye and brain disorders can cause peripheral vision loss and other visual field abnormalities. Visual field tests are performed by eye care professionals to detect blind spots (scotomas) and other visual field defects, which can be an early sign of these problems.

The size and shape of a scotoma offer important clues about the presence and severity of diseases of the eye, optic nerve and visual structures in the brain. For example, optic nerve damage caused by glaucoma creates a very specific visual field defect.

Other conditions associated with blind spots and other visual field defects include diseases of the retina, optic neuropathy, brain tumors and stroke.
