CAN LIGHT THERAPY HEAL EYE DAMAGE?

Laser therapy for eye damage ? Low level laser therapy not damaging Many of us worry about the possibility of cool lasers causing eye damage. This is an interesting study because it supports past research that cool or low level laser therapy (LLLT) and LED light are not damaging to the eyes. Laser therapy heals cellular damage In this study, rats were raised in dim light and then exposed to bright continuous light for 24 hours to create eye damage. Then, the animals were treated with 670nm light at the dose of 9 J/cm². As you might expect, the bright light caused damage to the rats’ eyes. Of interest is the fact that the cool, infrared light treatment or low level laser therapy healed the cellular damage. The researchers expressed the belief that infrared light is protective against light induced retinal damage even when it is applied after exposure. They also expressed the belief that it has the potential to become an important treatment to prevent or treat light damage to the retina. The researchers also felt that it could be beneficial in the prevention and treatment of retinal conditions involving many inflammatory mechanisms. Invest Ophthalmol Vis Sci. 2011 Mar […]
