Amblyopia is the most common cause of monocular vision loss in children [1],

with an estimated prevalence of approximately 2% in the United States [2–4].

A developmental disorder of spatial vision, amblyopia is clinically defined as

decreased best-corrected visual acuity (VA) in 1 or, less frequently, both

eyes, in the absence of any obvious structural anomalies or ocular disease.


The mainstay of amblyopia treatment is optimal refractive correction; significant

gains in visual acuity, beyond the immediate gains from simply eliminating optical blur, often occur with continued wear of the optical correction.

When patching is prescribed, it is reasonable to initially prescribe 2 hours of

daily patching for moderate amblyopia and 6 hours of daily patching for severe


Atropine penalization of the sound eye or full-time wear of a Bangerter filter can

be prescribed for first-line amblyopia treatment or for patients who do not comply

with patching.

The upper age limit for amblyopia treatment is not established, albeit there are

generally greater gains in visual acuity if treatment occurs before 7 years of age.


  • Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

    Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

  • Vision Therapy is well worth the expense, time and effort. Our son had a hard time focusing handwriting neatly. After vision therapy Seth could complete a task in half the time it previously took his abilities to focus and improved greatly and so did his handwriting.

    Also, he was better at listening. As a parent you wanted learning to be fun for our son and vision therapy made this possible.

  • Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

    He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

    It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

    Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

  • Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

    Thank you!
