Lazy Eye / Strabismus / Amblyopia
The term "Lazy Eye" is often confused. Many people understand lazy eye to mean an eye that turns in or out. The medical term for that is Strabismus. Amblyopia, which is different, means that the "wiring" between the eye and the brain was not developed and therefore visual information is not being procesed by the brain.
These two can be present at the same time. They can also occur separately. Someone can have:
| Strabismus with Amblyopia | This is common when one eye turns in relative to the other. |
| Strabsimus without Amblyopia | This occurs commonly when one eye turns out relative to the other. |
| Amblyopia without Strabismus | This frequently occurs when there is a large difference in power between the two eyes or if there is a high refractive condition in both eyes, such as high hyperopia in both eyes. Both eyes appera to point straight and therefore it is not aobvious to others. |
What is Strabismus ?
Strabismus means that the two eyes are not pointing to the same spot or position.
- This may occur all of the time (constant) or some of the time (intermittent).
- It can be the same eye that is mis-pointing (unilateral) or it can alternate, meaning that at times one eye points straight and at other times the other eye points straight. This is called alternating strabismus.
What is Amblyopia?
Amblyopia means that the information from one, or both eyes have not had the opportunity to develop the wiring from the eye to the brain.
Refractive Amblyopia:
-
Bilateral (both eyes) Amblyopia can occur if there is a high refractive condition that is about the same in both eyes.
-
Unilateral (one eye) Amblyopia occurs if there is a large difference between the two eyes. Usually, the eye with the higher refractive condition is the amblyopic eye, meaning the one that did not develop.
Strabismic Amblyopia:
When the two eyes do not point at the same position, then the Strabismus can bring on Amblyopia.
People are often told that nothing can be done past a certain age. This is simply not true. It is certainly easier to address at a younger age, but both children and adults can be helped, even when they have had surgery to "correct" the lazy eye.
