Does 'normal' vision improve with spinal manipulation?
OBJECTIVE
To discuss a patient whose spinal abnormalities may have caused subliminal visual field loss.


METHODS
A 22-yr-old man suffered from a painful neck. His vision was in the normal range, as measured by computerized static perimetry.


RESULTS
To define a guideline for a proposed investigation into visual field changes with spinal adjustment, his visual fields were tested before and after a normal office spinal manipulation. After this procedure, there was a measurable rise in the visual sensitivity of both eyes.


CONCLUSIONS
The use of computerized static perimetry changes to measure the cerebral effects of spinal manipulation is recommended for future chiropractic research.
