I've noticed some
confusion about the VOR, based on feedback I've gotten to my blog posts. So I'm posting some info below which is one
of the better explanations I've found online.... this is taken from the
Encyclopedia Britannica:
Alternative
title: VOR
VOR works
in conjunction with the optokinetic reflex (OKR),
which is a feedback mechanism that ensures that the eye moves in the same
direction and at almost the same speed as an image. Together, VOR and OKR keep
the image stationary on the retina, with VOR compensating for fast
movements and OKR for slower ones.
You can see from this
explanation that the VOR (in combination with the OKR) is very important. This is the main element - to my knowledge -
of vision for which your eyes and ears work together so completely.
It IS possible to have
balance problems that are not connected to vision, AND it's possible to have functional
vision problems that impact your balance that are not connected to your ears. For more info on vision, a good place to
start is the College of Vision Development - www.covd.org - which is an
international institute that provides special training for doctors (Developmental Optometrists), and vision
therapists.
As I've said before,
ophthalmologists and optometrists get little to no training re functional
vision problems, such as Convergence Insufficiency and Strabismus, two very
common diagnoses. If you think that there's
ANY chance you have a problem that does not have to do with your ears, or an
eye disease - get yourself checked!
Based on my experience, neural optometrists and neural
ophthalmologists can sometimes give a correct diagnosis re functional vision
problems, but do not have adequate knowledge re vision therapy. Again, in my experience, they understand the
neurology but not the functional, developmental aspects.
They may recommend VT, but often don't supervise it. This means that the necessary
individualization and titration of exercises may not be on target. Finally, as with any doctor, there are less
qualified folks out there - if you don't like who you're working with, keep
looking!
I'll be posting a blog in
the future that discusses flexibility, integration and stamina in relation to
neurological rehab....
