Amblyopia

I have had amblyopia in my left eye since childhood.
Although I wore glasses, I stopped wearing them after high school.
I only started wearing glasses again recently, but I have noticed that my vision is getting worse, and even my right eye's vision is starting to decline.
I would like to know if amblyopia can be treated and if it is possible to recover or prevent further deterioration of vision.

Regarding your question, the answers are as follows:
1.
What is amblyopia? Amblyopia refers to a condition where one or both eyes have a visual acuity that cannot be corrected to 0.8 or better with glasses, despite the absence of any pathological changes in the eye structures.

2.
The critical period for eye development is between the ages of 3 to 6 years, and the eyes typically mature before the age of 10.
Therefore, treatment for amblyopia is most effective during this critical developmental period (3 to 6 years).
If treatment is initiated after this period, the outcomes are usually less favorable.
3.
Amblyopic patients may have poorer vision; however, as long as there are no concurrent complications that could threaten vision, their visual status should remain stable, without sudden deterioration or blindness.
4.
In your case, if you have been wearing glasses for treatment until high school (around age 15), your vision should remain stable.
However, regarding the recent changes in your vision, it is important to determine whether there are any complications that could threaten your eyesight or if the changes are simply due to a shift in prescription.
It is advisable to undergo further examination to reach a conclusion.
Wishing you good health,

More Info

Amblyopia, commonly known as "lazy eye," is a condition characterized by reduced vision in one eye that is not correctable by glasses or contact lenses. It typically develops in childhood, often due to factors such as strabismus (misalignment of the eyes), significant differences in refractive error between the two eyes, or other visual impairments. The brain essentially favors one eye over the other, leading to a lack of visual development in the affected eye.

The good news is that amblyopia can often be treated, especially when diagnosed early. Treatment options vary depending on the underlying cause and the age of the patient. Here are some common approaches:
1. Corrective Lenses: Glasses or contact lenses can help correct refractive errors. For children, wearing the appropriate prescription can significantly improve vision in the amblyopic eye.

2. Patching: One of the most common treatments for amblyopia is the use of an eye patch over the stronger eye. This forces the brain to use the weaker eye, promoting visual development. The duration and frequency of patching depend on the severity of the amblyopia and the age of the child.

3. Atropine Drops: In some cases, atropine drops may be used in the stronger eye to blur its vision, encouraging the use of the weaker eye. This method can be more convenient than patching for some families.

4. Vision Therapy: This involves a series of visual exercises designed to improve coordination and focus between the eyes. Vision therapy can be particularly beneficial for children with amblyopia due to strabismus.

5. Surgery: In cases where strabismus is present, surgical intervention may be necessary to align the eyes properly. This can help improve the effectiveness of other treatments.

The critical factor in treating amblyopia is age. The earlier the treatment begins, the better the chances of recovery. While treatment is most effective in children, some studies suggest that even adolescents and adults may experience improvements in vision with appropriate therapy, although the outcomes may not be as favorable as in younger patients.

Regarding your situation, it is concerning that you have noticed a decline in vision in both eyes, especially after not wearing your glasses for an extended period. It is crucial to have a comprehensive eye examination by an eye care professional. They can assess the current state of your vision, determine if amblyopia is still present, and recommend a tailored treatment plan.

In summary, amblyopia can often be treated, and with the right interventions, it is possible to improve vision and prevent further deterioration. However, the effectiveness of treatment diminishes with age, so it is essential to seek professional help as soon as possible. Regular follow-ups and adherence to the prescribed treatment plan are vital for achieving the best possible outcomes.
