After one suffers a traumatic brain injury, many additional physical problems can occur as a result including vision problems. After traumatic brain injury, it is possible for the nerves or muscles that control eye movement to be injured. It is possible for the victim of a brain injury to experience a visual impairment such as double vision (diplopia), or the occurrence of two images at the same time. This condition can affect reading, walking, driving and other daily activities. In some cases, double vision isn’t constant and the symptoms may only occur during certain settings.
There are two types of double vision: monocular and binocular. In monocular double vision, the vision problem affects only one eye and does not go away when looking in different directions. When the affected eye is covered, the double images disappear. Binocular double vision affects both eyes.
