A former professor at the Southern College of Optometry in Memphis, TN, told me of an interesting experience. He said one of his instructors walked around a classroom, observing posture. His instructor could tell just by looking at their posture what visual problems the students he observed would likely have.
This was especially interesting to me, because I have a mild scoliosis. My spine curves in an “S” going one direction at the top, and balancing itself in a different direction at the bottom so that I am able to stand straight. You’d likely not even notice my scoliosis. But if you looked closely, you’d see that my right shoulder is lower than the left and it droops forward a little.
The Behavioral Optometrist who does my vision therapy confirmed that there is often a relationship between posture and strabismus. She thought my scoliosis was especially interesting also, since it is almost a mirror of the way my eyes compensate.
The outward turn of my eyes alternates from one eye to the other, so that when one eye gets tired and loses focus, the other eye compensates by carrying the focus. That arrangement lasted me well until recently when both eyes seem to tire of the focus more quickly.
Here’s an interesting item I found:
