Preliminary research indicates that SOME individuals presenting ADD
behaviors have a problem that may be called "constricted visual
performance field". This may be described as being something like
More research is needed on this. However it seems that some
individuals being diagnosed as suffering ADD may have a vision field
problem that can be easily shown. Of course the visual field problem
may be a result of the ADD, however there are a growing number of cases
where, when the fields are expanded with various methods, including
proper eyeglasses, the individual experiences considerable improvement.
In summary: Some of the individuals being treated for ADD are likely
to have an easily shown visual field problem. If it is only one in a
hundred, it is worth taking five minutes with all of them to find out
for that one.
I think it is highly unlikely that any significant number of children
diagnosed with ADHD owe their symptoms to this eye disorder.
In the first place, one would not expect to see developmentally
inappropriate signs of hyperactivity in these children, evidence for
which often goes back to _infancy_ in children diagnosed with ADHD.
Sure, it is unfortunate for the few individuals who do have this
problem (or a problem with gluten intolerance, other food allergies,
hypothyroidism, autism, etc.) to be misdiagnosed as ADHD.
But all these other causes combined can not explain the ADHD
phenomenon in the _vast majory_ of those who present the symptoms.
Finally, if the prevalence of the disorder you're desribing is
anywhere near 1:100, I think it would have been recognized long ago.
