Strabismus is a condition in which the eyes do not properly align with each other. The eyes don’t work together to look at an object or a person.

Strabismus is also known as cross-eyes or lazy eye. Up to 5 percent of children may be diagnosed with Strabismus. Strabismus usually occurs later in life. People may initially have double vision but that will eventually clear as the brain ignores the visual input from the affected eye.

What Causes Strabismus?

Strabismus can be caused by muscle weakness of the eyes. Each eye has six external muscles that control the eye movement. The muscles are controlled by cranial (brain) nerves. Strabismus occurs when there are neurological (stroke) or anatomical problems (tumors) that interfere with the function of the external muscles.

Babies who are delivered with forceps may suffer cranial nerve damage that affects the eyes. A stroke or brain tumors can cause strabismus. Family genetics also play a role in misaligned binocular vision.

Signs and Symptoms of Strabismus

  • Double vision
  • Blurred vision
  • Lazy eye (amblyopia)
  • Poor peripheral vision
  • Eyestrain
  • Headache
  • Vision loss

    Treatment for Strabismus

    Strabismus is treated by vision correction lenses (eyeglasses), medications or surgery.
