Strabismus is caused by a lack of coordination between the muscles in the eyes. This can happen due to:
- Problems, imbalances, or injuries of the muscles that move the eyes
- Uncorrected refractive errors (ie, the need for glasses)
-
Nervous system disorders that affect vision, such as:
- Problems or injury of the nerves that control the eye muscles
- Tumor in or near the eye or brain
- Strokes
or bleeding in the brain
- Increased pressure in the brain
- Myasthenia gravis
-
Hormone problems, such as:
- Vision loss in one eye (one blind eye will often turn in or out)
A risk factor is something that increases your chance of getting a disease or condition.
