H51.9: Disorder of binocular movement, unspecified

You cannot move one or both eyes properly.

The brain controls eye movement. It is responsible for moving both eyes at the same time and in the same direction. This is vital for our vision. Damage to certain parts of the brain can lead to problems with eye movement.

In your case, eye movement is impaired. Eye movement can be impaired in various ways. One or both eyes can be affected. For example, you may no longer be able to look in a certain direction. The eye movement can be impaired when looking to the side or upwards or downwards. When you want to see an object nearby, the eyes unconsciously point more inwards towards the nose. This unconscious movement can also be impaired.
