Amblyopia

Amblyopia is also known as a lazy eye, it’s a disorder insight in which the brain fails to process inputs from one eye and over time favors the other eye. After the underlying cause is resolved, vision isn’t restored right away, as the mechanism also involves the brain.


Amblyopia is detected when a parent or caretaker make notice of a child’s poor vision. Most of the time, it’s detected in the preschool vision screening. At the screening, they usually send home a paper to the parent with details on the discovery of amblyopia and direct them to get treatment.

Treatment usually takes place early on, the earlier the age, the better the results. By age 10, the visual system is normally stable and vision does not improve much with treatment.


There are different types of amblyopia; all forms result in reduced vision in the affected eye. Some of the different types are Strabismic amblyopia, deprivation amblyopia, refractive amblyopia, or a combination of all 3. There is also one that can affect both eyes, called bilateral amblyopia. Wearing glasses is very important and vision should be checked frequently. Amblyopia usually improves, however, it could take several years to complete treatment.


Strabismic amblyopia is when the eyes aren’t straight, it turns in, out, up or down. The brain learns to ignore that the eye isn’t straight. Vision drops drastically in the affected eye.


Deprivation amblyopia develops when a cataract or similar condition interfere with younger children, which deprives the child of clear vision. This is not treated at an early stage; most children never really learn to see well. Deprivation amblyopia is the least common condition.
Refractive amblyopia is the most common condition of amblyopia. It’s developed with uncorrected refractive errors, most of the time can be corrected with the right pair of glasses to correct the error.


Bilateral amblyopia can occur in children with large amounts of uncorrected Hypermetropia or astigmatism present in both eyes. The most common treatment for this condition is glasses. In some cases, there are other treatments that need to be taken on once the Doctor prescribes glasses and vision doesn’t improve. This condition is less common.
