Parent Teacher Conferences

Getting feedback from your child’s teacher is a vital part of the educational process so everyone can work together to ensure your child’s success.  Unfortunately, when a child has an undiagnosed vision problem at the root of his or her difficulties it can make academic success nearly impossible. 


Over 60% of children who struggle with reading and learning have vision problems which are typically 100% correctable, yet when undetected, these children continue to struggle and perform poorly on standardized tests.


Often a child with a vision problem that interferes with learning has excellent verbal skills causing parents and educators to think the child must be “lazy”, “not trying hard enough”, “AD(H)D”, “learning disabled”, etc. 


Vision screenings test a child’s ability to identify individual letters (acuity).  In reality, having 20/20 eyesight merely means you can see a certain size letter at a distance of 20 feet. 


Vision is a complex process that involves over 15 visual skills which are critical to academic success.

Vision Therapy for Traumatic Brain Injury

I recently published a case report in the peer-reviewed journal Optometry and Vision Development about a young man who suffered a head injury from a car accident 11 years ago.  He reported symptoms of chronic asthenopia, headaches, eye pain which developed after the accident.  Despite routine eye exams for glasses, he continued to struggle with these symptoms.  When I performed a neuro-optometric vision examination I found oculomotor, binocular, and accommodative dysfunctions which were very treatable with optometric vision therapy.  I prescribed a program of vision therapy to be performed in addition to his physical therapy program.  He started vision therapy immediately and found that it provided significant relief from his vision symptoms.

Vision therapy (VT), is the branch of optometric care devoted to developing, improving and enhancing people’s visual performance.  Good eye coordination and teaming skills are imperative to success in school or the work place.

Clear eyesight, or “20/20 vision”, isn’t all that’s required for close vision tasks.  Kids must have a variety of scanning, focusing and visual coordination skills for learning and for getting meaning from reading.  If these visual skills have not been developed, or are poorly developed, learning is difficult and stressful, and youngsters typically react in a combination of ways.    Joseph is a very bright boy who came to our office because he was struggling with reading and disliked school in general.  This is his success story:

Dear Dr. Tong,

I want to thank you deeply for all the help you’ve given to my son Joseph.  Before vision therapy, Joseph hated doing homework.  Every assignment was a struggle.  He would cry out of frustration when trying to copy words from one page to another.  He had great difficulty reading unless I sat with him and held a bookmark under the words to help him keep his place.  He resisted reading, and disliked school in general, even though he has always been a very intelligent and articulate boy.  After only a few sessions of vision therapy, Joseph’s reading improved dramatically.  He now enjoys reading, and voluntarily reads stories to this younger sister.  He is able to do written work without difficulty, and starts and completes his homework without being told.  He now has a very pleasant disposition in comparison to his former high frustration level.  Vision therapy has helped the whole atmosphere at our home.  Thank you!
