Photobiomodulation shows the power of light

[...]several studies with strong and moderate evidence in the past 5 years have shown encouraging results in treating eye diseases, such as AMD,11,12 retinopathy of prematurity, and diabetic macular edema, with a technique known as photobiomodulation (PBM).7-10 PBM has also been used in the last 20 years for musculoskeletal pain, injury, dysfunction, and wound healing; to improve acute muscle performance and reduce muscle damage after exercise;7 and for neuropathic pain, lymphedema, and oral mucositis1,3-15 PBM, or low-level light therapy, is the application of monochromatic light to a part of the body with the aim of repairing tissues and reducing inflammation, edema, and pain.7 The process is not a heat therapy, but is more akin to photosynthesis in plants. Intriguingly, this protocol seems to offer an extremely promising approach to prevent VA from worsening and to promote tissue repair in the dry form of AMD. [...]the approach has the enormous advantage of being entirely noninvasive. According to this hypothesis, at certain wavelengths, irradiation could regenerate retinal cells. [...]modulated light can offer a novel, valid therapeutic approach for dry AMD, which may facilitate the repair of damaged tissues in the retina and promote the survival and function of epithelial cells within the retinal pigmented epithelium.19
