Head injuries may result in loss of the Peripheral Vision.

Head injuries may result in loss of the Peripheral Vision. ‪Peripheral Vision‬ problems means that one doesn't have a normal, wide-angle field of vision, even though the central vision may be fine. Moderate and severe cases of peripheral vision loss create the sensation of seeing through a narrow tube, a condition commonly referred to as "tunnel vision." Symptoms of peripheral vision loss also can include difficulty seeing in dim light and decreased ability to navigate while you are walking.

If one witnesses a sudden decrease in peripheral vision, see the eye doctor immediately. Sudden loss of peripheral vision may indicate a detached retina, which is a medical emergency that must be treated as soon as possible to avoid permanent vision loss.
