Why would your eyes not move right to left or up and down?

The eyes are controlled by six muscles that work together to move them in different directions. If any of these muscles are damaged or paralyzed, the eyes may not be able to move right to left or up and down.

Some possible causes of eye muscle problems include:

* Strabismus, which is a condition in which the eyes do not align properly.

* Myasthenia gravis, which is a neuromuscular disorder that causes muscle weakness.

* Graves' disease, which is an autoimmune disorder that affects the thyroid gland.

* Botulism, which is a foodborne illness that can cause muscle paralysis.

* Head injury, which can damage the nerves that control the eye muscles.

* Stroke, which can damage the brain areas that control the eye muscles.

If you are experiencing problems with your eye movements, it is important to see an eye doctor for evaluation. The doctor can determine the cause of the problem and recommend the appropriate treatment.
