They might find it hard to align vertical and horizontal numbers in maths problems. Some might struggle to catch a ball because they can't get the timing quite right.
When should/can we detect a visual tracking problem?
Typically, a child develops the ability to process things visually and track moving objects around the age of 5 to 6. Since it is around this time that children are learning to read and write in school, their visual tracking skills are being developed too.
Why are tracking skills weak?
However, weaker tracking skills mean that reading and comprehension may suffer as their eye movements are not well coordinated so words and numbers may seem to jump around and meanings may become muddled, possibly affecting your child’s overall development and learning.

Why is visual tracking important?
Good visual tracking is essential to proper comprehension of reading material. The eyes have muscles to help move them in the positions that we need as the brain directs that movement. Without the brain understanding where the eyes need to be placed, the brain then starts to adapt the position of the eyes on the page as you will see below.
How to treat oculomotor dysfunction?
Treatment for Oculomotor Dysfunction usually includes a treatment program of vision therapy. Vision therapy involves using lenses, prisms, and specific eye and brain activities designed to improve fixation and saccadic eye movements; integrate oculomotor skills with vergence and accommodative systems; integrate oculomotor skills with information processing. Part of your treatment will be to become more aware of your eyes and how they are moving. This awareness helps to control the eyes. Sometimes patients don't know that they have a visual tracking issue and they just feel that their not as "smart" as other people. Conversely, those that have poor reading comprehension due to visual tracking issues often compensate to make up for the poor reading comprehension. Compensation may be that they write excessive notes to remember, highlighting the text, and heavy annotations.

Can a visual tracking disorder be misdiagnosed?
Because the symptoms of a visual tracking disorder are similar to many other disorders, it is commonly misdiagnosed. Unfortunately, even well-trained nurses, pediatricians, teachers, and other professionals fail to consider vision problems when they see children struggling to read, struggling to pay attention, or struggling to progress in school. They can also fail to see fidgeting, anxiety, and behavior problems as signs of undiagnosed vision disorders. These patients are often diagnosed as having Attention Deficit Disorder or Attention Deficit Hyperactive Disorder. Often times, if we can treat the underlying binocular vision disorder, the symptoms of ADD or ADHD will subside. Therefore it is important that school aged children are seen annually for a comprehensive visual assessment with an optometrist that tests binocular vision and visual skills in addition to acuity and general health of the eye.
Can oculomotor dysfunction be outgrow?
Oculomotor Dysfunction is not a condition you can outgrow. Instead, over time, an individual develops compensatory techniques – such as turning of the head while reading, rather than the head remaining stationary while the eyes move across the page of text. In kids, you can see adaptations more easily.

Rather than seeing one clear image, people with BVD might see an object slightly higher in one eye than the other. The brain rejects double images, so it forces the muscles in your eyes to correct the misalignment. Over time, this puts a strain on your eye muscles, leading to BVD and symptoms like eye tracking problems.

Keep a list so that you can reference specific issues when you speak with your child’s teacher or a specialist. 2 Talk to Your Child’s Teacher#N#Take your list of concerns to your child’s teacher and have a conversation about any visual processing difficulties he or she has noticed in the classroom. Ask whether these issues are getting in the way of your child’s reading comprehension or social development. 3 Request an Evaluation#N#Poor vision and visual processing disorder are different issues that require different interventions, so it’s important to rule out any vision or eye issues by having your child’s sight checked by a pediatrician or ophthalmologist. If vision proves not to be an issue, talk to your child’s school about getting his or her visual comprehension skills measured. 4 Be Proactive and Trust Your Gut#N#As a parent, you are your child’s best advocate. If your child’s school assures you that nothing is wrong, but you sense that there is an issue, don’t be afraid to have your child evaluated for visual processing issues.
