Is hyperactivity a vision problem?

I know a boy who is autistic (and hyperactive). When he is in a car he
is very quiet, but when he is in the house he runs here and there. It
is as if he sees the world moving when he doesn't.

Perhaps he sees the world moving when he is still and so he has to
move for it to make sense.Has anyone ever done research on the visual
problems of hyperactive kids? If so,please let me know.

I certainly never experienced such a perception when I was a hyperactive
(but not autistic) kid. I vaguely recall that amblyopia (suppression of
one eye) *may* be more common in hyperactive kids than in the general
population, but I've never heard it posited as a *cause* of hyperactivity;
if the association is really there, it's likely the result of a common
underlying cause rather than direct causation between the two symptoms. In
any case it wouldn't produce sensations of false motion.

It's possible that in an autistic kid what seems to be hyperactivity isn't
the result of ADHD at all, but rather of attempts to self-stimulate. This
is actually a pretty good illustration of why real medical diagnosis isn't
done with symptom checklists; most symptoms can have many possible causes,
and a real diagnosis isn't based on jumping at the first one that occurs to
the practitioner.
