What is divergent strabismus?
There are a number of treatments available for a divergent squint, which is otherwise known as divergent strabismus. People suffering this condition have one eye that turns outwards, which can cause embarrassment and poor vision in the affected eye if left untreated.
How does strabismus affect the brain?
When this occurs, two different images are sent to the brain — one from each eye. This confuses the brain. In children, the brain may learn to ignore (suppress) the image from the weaker eye. If the strabismus is not treated, the eye that the brain ignores will never see well.
What part of the brain is affected by strabismus?
Strabismus can be caused by problems with the eye muscles, the nerves that transmit information to the muscles, or the control center in the brain that directs eye movements. It can also develop due to other general health conditions or eye injuries.
Does strabismus affect depth perception?
For example, children who have strabismus have trouble with depth perception because their eyes are misaligned. So, glasses can help some of them by helping straighten their eyes. However, other children may need surgery to straighten their eyes, and they might still need to wear glasses after the surgery.
What causes divergent strabismus?
Strabismus can occur due to muscle dysfunction, farsightedness, problems in the brain, trauma or infections. Risk factors include premature birth, cerebral palsy and a family history of the condition.
What causes divergent squint?
Exotropia occurs when there’s an imbalance in eye muscles or when there’s a signaling issue between the brain and eye. Sometimes a health condition, like cataracts or stroke, can cause this to occur. The condition may also be inherited.
Is strabismus neurological?
Most strabismus is the result of an abnormality of the poorly understood neuromuscular (including brain) control of eye movement. Less commonly, a problem with the actual eye muscle causes strabismus.
What happens if strabismus is not corrected?
Strabismus usually can be fixed when found and treated early. If it’s not treated, the brain eventually will ignore the visual images of the weaker eye. This change — called amblyopia, or “lazy eye” — can make vision blurry, cause double vision, and harm a child’s depth perception (seeing in 3D).
What does a person with strabismus see?
When a kid has strabismus, the eyes don’t focus together on the same object and each eye sends a different picture to the brain. As a result, the brain might see two images (double vision) or the object looks blurry. Kids’ brains are really smart, and they don’t like getting two different pictures instead of one.
What is the main cause of strabismus?
Stroke (the leading cause of strabismus in adults) Head injuries, which can damage the area of the brain responsible for control of eye movement, the nerves that control eye movement, and the eye muscles. Neurological (nervous system) problems. Graves’ disease (overproduction of thyroid hormone)
Is lazy eye the same as strabismus?
Most people automatically use the term Lazy Eye when an eye crosses or turns outward. As stated above, an eye that moves on its own is a sign of Amblyopia or Lazy Eye, but Strabismus is the condition that one or both eyes turns inwards (esotropia) or out (exotropia).
