Relationship between visual skills and childhood conditions:
Attention Deficit Disorder and Visual Skills
research reported by Dr. David B. Granet at the April, 2000, meeting
of the American Academy of Pediatric Ophthalmology & Strabismus
indicated that a visual disorder known as Convergence Insufficiency
is three times more common in children diagnosed with Attention
Deficit Disorder (ADD/ADHD) than in the general population.
Convergence Insufficiency is characterized by a
person's inability to maintain proper alignment of both eyes on objects
as they approach from far to near. A Convergence Disorder likely
results in Intermittent Central Suppression(ICS) and is correctable
by our vision training method. Many of the symptoms typically used
to diagnose ADD/ADHD are also recognized as symptoms of learning-related
visual problems.
Dyslexia is a common diagnosis of children who
can not read well. ICS is an on and off (intermittent) nerve shutdown
(suppression) from one eye to the brain. This allows the suppressed
eye to momentarily drift away from the words being read. When the
nerve signal from the eye is again sent to the brain, the eye is
not looking at the correct location on the line, causing confusion
in the direction of reading, skipping words, misreading words, etc.
This may also result in reversals of letters or numbers when reading
and writing.
Eye-hand coordination problems Often in elementary
years, teachers may note that a child has unusual difficulty coloring within
the lines, drawing, writing, cutting with scissors, and other skills
that require the eyes and hands to work together. Sometimes these
children also have difficulty determining slight differences and
recognizing similarities in visual material.
Learning Disabilities
Educators who note a serious discrepancy between a child's
intellectual ability (IQ) and his or her academic ability or performance
in one or more subject areas may determine that the child is learning
disabled. This is a generic term that may represent any of a number
of specific learning problems observed by teachers and parents. While
there are many possible causes, the child should be screened for
ICS and other visual pathway problems as part of a comprehensive
evaluation.
What does this mean? This means that any child who is diagnosed
as dyslexic, learning disabled, ADD/ADHD, or has eye-hand (visual-motor)
coordination problems, or is suspected of having one or more of these
conditions, should be screened for ICS and/or a convergence disorder.
This is especially true if the child scores over 30 on the Visual
Skills survey in this web site.
Experts have long believed that the nervous systems are atypical
(different) in dyslexic, ADD/ADHD, and other learning disabled individuals.
The goal of vision therapy is to retrain the brain to function in
a more typical manner so that the individual can learn in the same
way as other children in the classroom.
