Crossed Eyes Causes & Risks

Causes

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:
  • Diabetes
  • Thyroid disease
• 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.
