Amblyopia

Hello Dr.
Ke,
I would like to ask some questions regarding amblyopia.
Recently, I discovered that I have a significant amblyopia issue during a medical examination for military service.
After wearing glasses, my right eye measures 0.6 and my left eye measures 0.3, with the refractive error being -7.75 for the right eye and -3.75 for the left eye.
However, during a second examination where they administered a pupil dilator, the results indicated that after ciliary muscle paralysis, my corrected vision is 0.6 (-700) for the right eye and 0.3 (-300-150x180) for the left eye, with astigmatism in the left eye similar to amblyopia.
There is a 400-degree difference between my two eyes, but even after correction, I still do not reach 0.8 in both eyes.
My best vision seems to be as it is now.
Sometimes, I have difficulty seeing clearly while driving at night.

I am considering undergoing laser surgery for vision correction, but I wonder if someone with severe amblyopia like mine can undergo such a procedure.
I would like to know what kind of improvement I can expect if I proceed with the correction.
At 22 years old, am I destined to wear glasses for the rest of my life, or is there a possibility of treatment through current medical technology? I am very afraid that one day my vision will gradually deteriorate.
What kind of surgeries might be available to me? Could you please provide your advice?

Hello: Laser refractive surgery can correct refractive errors, but it will not improve best-corrected visual acuity.
Even after undergoing laser surgery, your best vision may still be 0.6 and 0.3.
Amblyopia is fixed and will not gradually worsen, but it is important to investigate why your vision is only 0.6 and 0.3.
It would be helpful to know the visual acuity of your parents and siblings.
Anisometropia may be hereditary, and an ophthalmologist can help identify the underlying causes to determine if there is a possibility for your offspring to improve their vision.
Sincerely, Dr.
Komeilan, Ophthalmology.

More Info

Amblyopia, commonly referred to as "lazy eye," is a visual development disorder that occurs when one eye fails to achieve normal visual acuity, even with the help of corrective lenses. This condition typically arises during childhood and can lead to significant visual impairment if not treated early. As you are now 22 years old and have recently been diagnosed with severe amblyopia, it is understandable to have concerns about your vision and treatment options.

Understanding Amblyopia
Amblyopia is often characterized by a significant difference in the refractive power between the two eyes, which can lead to the brain favoring one eye over the other. In your case, the difference in refractive error between your right eye (-7.75) and left eye (-3.75) is substantial, which is a common cause of amblyopia. The brain may suppress the input from the weaker eye to avoid double vision, resulting in reduced visual acuity in that eye.

Treatment Options
1. Corrective Lenses: The first line of treatment for amblyopia is usually the prescription of corrective lenses. In your case, wearing glasses can help improve the clarity of vision in both eyes. However, as you have noted, even with glasses, your vision has not reached the desired level.

2. Occlusion Therapy: This involves patching the stronger eye to force the brain to use the weaker eye. This method is most effective in younger children but can still be beneficial for older individuals, depending on the severity of amblyopia.

3. Vision Therapy: This is a structured program of visual activities designed to improve eye coordination and focusing abilities. It may include exercises that help strengthen the weaker eye and improve visual processing.

4. Surgical Options: In some cases, surgery may be considered, especially if there are underlying issues such as strabismus (misalignment of the eyes). However, surgery alone does not treat amblyopia; it must be combined with other therapies.

5. Laser Surgery: You mentioned the possibility of undergoing laser surgery. While laser surgery can correct refractive errors, it is generally not recommended for amblyopia, especially if the condition is severe. The effectiveness of laser surgery in improving vision in amblyopic eyes is limited, and it does not address the underlying issues of visual development.

Future Outlook
At 22 years old, your visual system is fully developed, which means that the potential for improvement may be limited compared to younger individuals. However, this does not mean that you cannot achieve better visual outcomes. Many adults with amblyopia have benefited from various treatments, including vision therapy and corrective lenses.

Concerns About Vision Loss
It is natural to worry about the future of your vision, especially with a diagnosis of amblyopia. While amblyopia itself does not typically lead to blindness, it can result in significant visual impairment. Regular eye examinations and appropriate treatment can help manage your condition and maintain your vision.

Recommendations
1. Consult an Eye Specialist: It is crucial to work with an ophthalmologist or optometrist who specializes in amblyopia and adult vision therapy. They can provide a comprehensive evaluation and tailor a treatment plan specific to your needs.

2. Explore All Treatment Options: Discuss all available treatment options, including the potential benefits and limitations of each. Be open about your concerns and goals for your vision.

3. Consider Vision Therapy: If you have not already, inquire about vision therapy as a potential option to improve your visual function.

4. Stay Informed: Keep up with advancements in treatments for amblyopia and other eye conditions. New techniques and therapies are continually being developed.

In conclusion, while amblyopia presents challenges, there are treatment options available that may help improve your vision. It is essential to seek professional guidance and explore all avenues to achieve the best possible outcome for your visual health.
