Strabismus or crossed eye causes may be due to muscular, nerve or other general health problems discuss in detail.

What causes strabismus?

  • Eye muscle problems,
  • Nerve problem that transmits information to the muscles,
  • Problem with the brain's control center that controls the eye movements
  • Other general health conditions or eye injuries

Risk factors for developing strabismus

  • Family history - individuals with parents or siblings who have strabismus are more likely to develop it.
  • Refractive error - people who have a significant amount of uncorrected farsightedness (hyperopia) may develop strabismus, because of the additional amount of eye focusing required to keep objects clear.
  • Medical conditions - people with conditions such as Down syndrome and cerebral palsy. Alternatively, who have suffered with a stroke or head injury.

Although there are many types of strabismus that can develop in children or adults, the two most common forms are accommodative esotropia and intermittent exotropia.

Esotropia and its symptoms

Accommodative esotropia mostly occurs because of uncorrected farsightedness or hyperopia. Because the eyes focusing system is linked to the system that controls where the eyes point, the extra focusing effort needed to keep images clear in farsightedness may cause the eyes to turn inward.

Signs and symptoms of accommodative esotropia may include seeing double vision, urge to close or cover one eye when doing close work, and tilting or turning of the head.

Exotropia and its symptoms

Intermittent exotropia may develop due to an inability to coordinate both eyes together. The eyes may have a tendency to point beyond the object being viewing.
Signs and symptoms of intermittent exotropia may include headaches, difficulty reading, and eyestrain. They also may have a tendency to close one eye when viewing at distance or in bright sunlight.
