The human being is in a constant state of change. The static neurological assessment of the visual field is normally measured by automated instrumentation as explained in the Field of Vision. A functional visual field can be measured by a Campimeter which may determine the amount of visual information that may be actually processed and understood by the visual system. A further ability to use visual processing can be measured from a technique called Binocularity. As the syntonics is administered each session the amount of information processing is measured and graphed.

Of particular interest with the visual field, is where the retinal fibers come together and leave the posterior portion of the eye there is actually a hole created in your field as no receptors are covering where the nerves exit the eye. There should normally be a specific size and position in the retina and is called the blind spot. The blind spot in each eye is same side as the name of the right or left eye you are looking with. Since they are on opposite sides, we never notice that we have a small blind spot when looking.

When this has become displaced or measures larger than normal, it could very well be involved with some disruption in the alignment of the spinal column in particular the neck(cervical) area. There are seven vertebrae in the neck that support the skull and the 2nd and 3rd are located where a portion of the Sympathetic (Voluntary) nervous system has a junction.

When moving your head down it reflexes to the visual mechanism to gain awareness of a change in where space is located, and a reflex to the ocular muscles to turn the eyes inward. If there is not proper alignment of the vertebrae then some wrong signals could be processed confusing some ones location in space and the proper reflexes on moving the eyes for reading and close work.

Dr. Pharr has developed some new understanding of the effect of Cranial Dysfunction’s and cerebral spinal fluid flow, and how the application of Craniopathy techniques may have a direct effect on the visual function of our awareness and perception.

To gain the maximum level of care, any portion of the structural system that may be interfering must be addressed with appropriate referral to specialist, such as Chiropractors, Osteopaths who have the specialized knowledge to correct such problems. A recent more Technical Article can be found that appeared in the Journal of Optometric Phototherapy April, 2000.

If there is actually displacement of the position of the optic nerve (labeled Dural Torque), this can further indicate that the skull(cranium) itself may actually be out of proper alignment. This is a highly specialized form of therapy in adjusting the skull, but it actually makes a slight movement each time we breath, circulating the cerebral spinal fluid.
