Low-level Light Therapy of the Eye and Brain

“Beneficial in vivo effects of LLLT on the eye have been found in optic nerve trauma, methanol intoxication, optic neuropathy, retinal injury, retinitis pigmentosa, phototoxicity, and age-related macular degeneration. Beneficial in vivo transcranial effects of LLLT on the brain have been observed in anoxic brain injury, atherothrombotic stroke, embolic stroke, ischemic stroke, acute traumatic brain injury, chronic traumatic brain injury, neurodegeneration, age-related memory loss, and cognitive and mood disorders. No adverse side effects have been reported in these beneficial applications of LLLT in animals and humans. The authors conclude that LLLT is a safe and beneficial approach, based on scientifically sound mechanisms of action of red to near-infrared light on cytochrome oxidase, with neurotherapeutic promise for a wide range of ophthalmological, neurological, and psychological conditions.”
