Nice item in Science Daily News on research from Johns Hopkins concerning the connection between vision problems and vestibular function. I blogged previously about recognition of these issues in Optometry and in Occupational Therapy, as elaborated by Developmental ODs in California, and the grandmother of Sensory Integration, Jean Ayres. The Hopkins group did SBO vs. SBC a bit differently – on a foam pad rather than standing on one leg, but their report substantiates the need to consider that the eye bone is connected to the hip bone.
Here is a nice reminder of how the VOR, or Vestibulo-Ocular Reflex, helps the eyes serve as the brain’s global positioning and navigation systems. It’s good to take a step back and realize that eye docs have known for many years that being in motion can smear your vision, even for something as basic as reading an eye chart, as discussed in this article. The nature of smear in visual targets can be distortion, blur, ghosting, instability, or a lag in your brain re-claiming clarity.
We’ll visit this further with some discussion about integrating optometric vision therapy with occupational and physical therapy, embodied in Mary Kawar and Sheila Frick’s visual-vestibular Astronaut Training.
