Syntonic Phototherapy (Light Therapy)

Syntonic Phototherapy, often referred to as light therapy, is a treatment used for vision problems following concussion. Treatment consists of laying beneath a lamp, with the lights off. A colored light filter will be taped over the lamp or the patient will wear a pair colored glasses for approximately 20 minutes. The color used will vary based on the problem being treated. Typically red stimulates the sympathic nervous system, while indigo activates the parasympathetic system. Visual deficits seen in post concussion syndrome that may benefit from light therapy are accommodation, binocularity, visual processing, and functional visual field. This is just one tool in the developmental optometrist tool box. Ask your local provider if it's right for you.
