S04.4: Injury of abducent nerve

Various nerves run from the brain to the sensory organs in the head, and to organs in the body. These nerves are called cranial nerves. These nerves are important in seeing, tasting or hearing, for example. But the cranial nerves also control important functions in the body, such as in the lungs and heart.

Various nerves control the muscles used to move the eyes. You have injured one or more of these nerves. As a result, you may no longer be able to move your eyes properly. If you cannot move your eyes properly, you can have problems with your sight. For example, you may have double vision.
