The visual system connects with the sensory system to provide information for coordination of balance, movements and thoughts.

The figure below is a simplified drawing of how the brain is laid out.  The functional areas of the brain are not isolated but connected in many ways.  The visual pathways are connected to at least 34 other centres in the brain that are dealing with physiological dynamics other than vision:

Connecting Vision and Body

The “traditional model” of optometry considers visual dysfunction as a structural problem whereas the “developmental model” recognises that vision is a dynamic process, which controls the action of the entire body and, in turn, is influenced by feedback from other sensory systems. Vision is not a static receptor of information but an interactive one. 70% of all sensory nerves in the entire body receives impulses from the eyes. Learning difficulties, behavioural problems, poor coordination and developmental delay may be the result of retained neonatal reflexes (also known as primitive reflexes).
