What Happens in Vegas Goes to Your Office


The Annual COVD meeting is fast approaching, and one of the lectures toward which I’m looking forward with great anticipation will be by Zoi Kapoula.  As I blogged about previously, Zoi is an internationally regarded authority in the research of vergence control and postural stability.  I’m hoping that this will be one of many lectures where what we hear and see in Vegas won’t stay in Vegas, but will follow us to our offices.  In my seminar on vision to OTs, PTs, and SLPs, I make reference to Ayres’ Test done as Standing Balance Eyes Open vs. Eyes Closed.  We talk about the visual support of balance, with particular reference to postural sway and midline shift.  I’ve speculated about the influence of binocular control on postural sway, and yesterday Dr. Michael Margareten circulated a nice article from the Journal of Vision on the subject.

While the gain in the VOR system is a big part of postural control, and relates heavily to the influence of lenses and prisms, there are numerous visual factors.  Zoi Kapoula will be reviewing saccades and vergence in a developmental context and in doing a search of my files I came across this diagram from NeuroCom that we’re going to discuss in our office to put the visual components of balance control into perspective.  Thought you might enjoy it.
