Paper Abstract

Syntonic phototherapy is an application of clinical phototherapy that is not well known by most LLLT photobiomodulation researchers and clinicians in spite of its long history. This is because of three main reasons: this approach was beyond the limits of the "reasonable" scientific paradigm, it has not been well researched and it is used mainly by optometrists. Clinical and basic researcher in the last decades about light's impact on cells, tissues, blood, circadian rhythms and mood disorders has broadened the paradigm and increased the acceptance of light as a healing agent. Perhaps now is an appropriate time to describe Syntonic optometric phototherapy with the purpose of exciting research to validate and expand its use. Syntonics uses non-coherent, non-polarized, broad-band light delivered into the eyes to treat brain injury, headache, strabismus, eye pathology, learning disability, mood and developmental syndromes. The eyes permit direct, non-invasive application of light to the retinal blood supply and to non-visual, retinal photoreceptor systems that signal circadian and other brain centers. Patients look at prescribed colors for 20-minutes/day for twenty treatments. Visual field, pupil, and binocular testing, medical history and current symptoms determine the syntonic filter prescription. Presentation describes syntonic theory, phototherapy device, visual field and pupil tests and cases reports with pre- and post-data and case resolution.
