Visual Processing and PressVision

What is Visual Processing?

Our visual system functions as two interconnected pieces. What occurs in the eye is considered to be the hardware component of vision and what occurs in the brain is considered to be the software component. This is a bit simplistic because in humans at least 10 to 15% of the information regarding what we see is passed on to the visual centers of the brain from sources other than the eyes. We refer to this as subcortical vision, and it includes pivotal centers for balance and movement.

It is widely recognized now that in sensory systems the distinction between what occurs in the brain and what occurs through the end organ is crucial. When we speak of a child with auditory processing problems, no one says "Oh, do you mean she needs a hearing aid?" It is understood by ENTs, audiologists, speech-language pathologists, and educators that how the brain processes incoming sound is quite distinct from the condition of the ears, and they must work in concert.

Yet somehow we persist with a very antiquated notion that if the condition of the eyes is normal, everything is fine with vision. This one misconception results in a false sense of security that allows thousands of children to continue to struggle with learning. Much as ENTs do not proclaim that all aspects of hearing must be fine if the ears are normal, eye doctors should not conclude that all aspects of vision must be fine if the eyes are normal.
