Concussion Treatment: Convergence Deficiency


By: Joel Luedke

Found this on Mike Reinold's website by a guest writer and it was something I had neither heard of or  thought about in the treatment and management of concussions. Concussion Treatment: Convergence Insufficiency



In the article it talks about the four visual components: Accommodation, Vergence, Divergence, and Convergence.



The article talks about convergence solely which is the ability to move medially, towards the nose, which allow for single vision of closer objects, the ability to cross your eyes.  The article talks about working on convergence to help with relieve of concussion symptoms in a quicker manner.  This will help address the daily activities of athletes that bother them even after they feel good at complete rest.



"Normal" convergence is starting to get diplopia within 4-6 cm from the nose-meaning, they are able to move both eyes medially to focus on the target, keeping it as one, up until that point.  For those with concussion, it is common to get diplopia at 15-20cm or not at all.



The author, Shaun Logan DPT, reviews more on treatment of convergence deficiency in his article here:  Concussion Treatment: Convergence Insufficiency




Update: 1/28/16

This is something we have begun to implement a screening on along with our concussion protocol at UWL.  It is very interesting and one that is a 'new' wave of looking at multiple facets of what could be causing concussion symptoms and possibly prolonging them.  When your eyes can't do what they are supposed to we need to be able to identify it and so that way we can go back and work to correct it.  The corrections are highly interesting consisting of actual training and also adjustments to lenses to help readjust your vision.

Incredibly pioneering stuff going on.
