Each year, the College of Optometrists in Vision Development promotes August as Vision and Learning Month. What’s this all about?
With school starting soon, it’s an excellent time for an eye exam. After all, up to 80% of learning comes through the visual system. The problem parents and their kids run into is that many kids have “20/20” visual acuity (meaning they can read the smallest letters on the eye chart) yet still have vision problems that can get in the way at school.
What type of eye doctor evaluates the 17 visual skills necessary for school success? A Developmental Optometrist specializes in testing and treating all of the visual skills necessary in the classroom. Seeing clearly and having healthy eyes (which is tested by your primary care optometrist or ophthalmologist) are important, but just a starting point.

There’s still time– schedule your child’s back-to-school eye exam today!

R.M., a 28-year-old man, was getting headaches more and more frequently when using a screen. As someone who spent most of his workday on the computer, this was a problem. A previous eye doctor told him he was out of luck, too old to fix his problem. R.M. had amblyopia, and his new eye doctor had referred him to me.
Last weekend was the 61st Annual Kraskin Invitational Skeffington Symposium (KISS), held in Bethesda, MD. One of the most exciting presentations was given by Dr. Paul Harris, a prolific author, developmental optometrist and professor at Southern College of Optometry. He reported that a group of scientists and clinicians are preparing a publication with new clinical guidelines on the treatment of amblyopia.
The old paradigm for amblyopia treatment is something most people are familiar with to some degree– patching. I think most adults can think back and remember a child at school wearing a stick-on eye patch, and probably getting teased about it. While patching can temporarily improve visual acuity (how many letters you can read off the eye chart), it does nothing to improve the other visual problems present in amblyopia, such as difficulties with eye strain, visual crowding, contrast sensitivity, and using the eyes as a team (among others).
Newer research has shown that not only is patching not the best method of treating amblyopia, it’s not even necessary except during active therapeutic activities. Instead, treating the entire visual system –as a system— produces superior results that last. The key is that amblyopia is not a “lazy eye”, but rather a problem in how the brain uses the two eyes.
It’s interesting that using whole system, or binocular vision, techniques is described as “NEW“, when Developmental Optometry has been doing this clinically for a hundred years.
Developmental optometrists had been using binocular vision perceptual learning techniques for decades before the concept hit the mainstream in research. In the last 25 years, perceptual learning as it relates to vision therapy has been discussed more and more in the fields of psychology and vision science. Many computer games have been developed that capitalize on perceptual learning to develop true and lasting visual skills. However, I and my developmental optometry colleagues have found that working in 3D space (rather than a flat 2D screen) generates a knowledge of “Where am I?” and “Where is it?” that more easily translates into real-world visual scenarios.
Another important acknowledgement in the current scientific literature is that there is no cutoff age for improvement of visual skills and development of binocular 3D vision. Instead, using a binocular vision approach to therapy in conjunction with appropriate compensation of refractive error (glasses or contact lenses), yields excellent results. This mirrors what we have seen clinically. Adult patients frequently reach normal or near-normal levels of visual performance, and in nearly all cases see significant improvements in quality of life.
Publishing new treatment guidelines, taking into account all of the data supporting established developmental optometry clinical therapies, will bring amblyopia remediation out of the dark ages and provide hope to so many patients who have been told, “It’s too late for you.”
As for R.M., as he completed vision therapy, he no longer experienced headaches and eye strain. He was more productive at work, and very happy that his efforts had paid off. He wasn’t too old, after all!
For the nerds, some additional papers on perceptual learning, adult amblyopia, and vision:
K. describes the results of vision rehabilitation after an autoimmune disease flare-up left her visual world in disarray.
The science of brain plasticity is abundant with new ideas! Dr. Green and I just returned from the NORA (Neuro-Optometric Rehabilitation Association) conference in Denver. We spent four full days learning about the vision repercussions of whiplash, concussion, stroke, and other neurological injuries. There is so much more for us to learn, but we were able to bring home some great new ideas to help all of our patients in the therapy room.
We learned new ways to interpret the information from the VEP (Visual-Evoked Potential), a specialized
form of EEG that actually measures the brainwaves created by visual input. It tells us how much visual signal is getting through, and how strong that signal is. We’ve also learned that it can give us information about what the brain is doing when it’s waiting for the visual signal, and how we can change that with specialized lenses.
The VEP is appropriate for any neurological insult; strabismus, amblyopia, and some other vision disorders. If you’d like more information or would like to know if you are a candidate, please email me or call (301) 951-0320.
Another great new learning opportunity is on the horizon. In June, I will be attending a workshop outside of Chicago where I will be learning about Syntonic Phototherapy. This is a technique in which specific wavelengths of light are used to change the person’s nervous system response and can greatly augment vision therapy. You may be familiar with how Seasonal Affective Disorder is treated with a special light; this is a similar concept but much more specifically tailored to the individual.
School is out soon, but learning never ends!
It is important to understand that while our eyes take in visual information, that information is sent to the brain where it is processed. If the information that is sent to the brain is faulty, it can make learning very difficult.
While learning disability websites list a variety of accommodations that can help children with Visual Information Processing Disorders, it is important for parents and educators to understand that these are signs that a correctable vision problem is playing a role in a child’s learning challenges.
Many individuals with learning disabilities also have ADHD (Attention Deficit Hyperactivity Disorder). One of the signs that a vision problem may be contributing to one’s learning challenges is a short attention span when it comes to reading and near work. This behavior could easily be mistaken for ADHD.
A study published in the November 2013 issue of the Journal of Attention Disorders states that “attention and internalizing problems improved significantly following treatment for Convergence Insufficiency.” Convergence insufficiency is an eye coordination disorder which can make reading difficult and cause symptoms such as eye strain, double vision, loss of concentration, and frequent loss of place when reading and working up close, all which play a negative role in learning.
The National Eye Institute of the National Institutes of Health recently funded a 5-year, 8 million dollar study called the Convergence Insufficiency Treatment Trial – Attention and Reading Study (CITT-ART). This will be a national multi-center clinical trial that involves optometry, ophthalmology, psychiatry, and education in evaluating how this eye-teaming problem impacts a child’s attention and reading performance.
These studies are very exciting because we are sure they will prove what we have seen in our patients over the years: Vision problems, including eye coordination and eye movement disorders, can and do impact the ability to read and pay attention. We are able to help children and adults.

October is Eye Injury Prevention Month, so let’s take a minute to consider a couple of common sense eye safely tips this Halloween.
Is this how you want your costume to turn out?
Using flea-market, beauty shop, or internet purchased contact lenses without a proper fitting is setting yourself up for an ugly eye that lasts well past Halloween night. The FDA is cracking down on unlicensed vendors and educating the public about poorly-fitted lenses. Don’t go blind! Most optometrists can properly fit decorative lenses at a reasonable price.
This costume looks cool, but it would be easy to get hit by a car or fall down the steps when your vision is impaired by this mask. Wigs or scarves should be kept out of kids’ eyes, too.
Choose makeup instead, especially for young children. Check that it’s approved for use around the eyes, or better yet, avoid the eye area.
