What is strabismus in adults?
Strabismus means that both eyes don’t look at the same thing at the same time. One eye may look straight ahead while the other eye looks in another direction. It is sometimes called “cross-eye” or “walleye.” It happens when the eye muscles don’t work together to move both eyes in the same direction at the same time. This sends two different images to the brain.
What are the symptoms of strabismus in adults?
The most common symptoms are:
• Blurred or double vision.
• Problems with seeing out of the side of your eyes (peripheral vision).
• Problems with seeing how far things are away from you (depth perception).
• Seeing two different images, one on top of the other (visual confusion).
• Lazy eye (amblyopia).
• Eyes that don’t move together.
• Squinting or closing one eye.
What causes strabismus in adults?
Sometimes adults have strabismus from childhood. Childhood strabismus often has no known cause. But it tends to run in families.
Adults may develop strabismus from eye or blood vessel damage. Other causes include loss of vision, a tumor in the eye or brain, Graves' disease, stroke, and diabetes. Some muscle and nerve disorders can also cause it.
