Abstract Photobiomodulation (PBM) also known as low-level level laser therapy is the use of red and near-infrared light to stimulate healing, relieve pain, and reduce inflammation. The primary chromophores have been identified as cytochrome c oxidase in mitochondria, and calcium ion channels (possibly mediated by light absorption by opsins). Secondary effects of photon absorption include […]
Biphasic Dose Response in Low Level Light Therapy
Abstract The use of low levels of visible or near-infrared light for reducing pain, inflammation, and edema, promoting healing of wounds, deeper tissues, and nerves, and preventing cell death and tissue damage has been known for over forty years since the invention of lasers. Despite many reports of positive findings from experiments conducted in vitro, […]
Biphasic dose response in the anti-inflammation experiment of PBM
Abstract Non-invasive laser irradiation can induce photobiomodulation (PBM) effects in cells and tissues, which can help reduce inflammation and pain in several clinical scenarios. The purpose of this study is to review the current literature to verify whether PBM can produce dose effects in anti-inflammatory experiments by summarizing the clinical and experimental effects of different […]
Anti-inflammatory effects of low-level laser therapy (LLLT) with two different red wavelengths (660 nm and 684 nm) in carrageenan-induced rat paw edema
Abstract It has been suggested that low-level laser therapy (LLLT) can modulate inflammatory processes. The aim of this experiment was to investigate what effects red laser irradiation with two different wavelengths (660 nm and 684 nm) on carrageenan-induced rat paw edema and histology. Thirty two male Wistar rats were randomly divided into four groups. One group received a sterile saline injection, […]
Non-invasive Treatment of Early Diabetic Macular Edema by Multi-Wavelength Photobiomodulation with the Valeda Light Delivery System
Abstract Purpose : The complex pathophysiology of DME results in extracellular fluid accumulation and in decreased visual function. Light-based Photobiomodulation (PBM) provides a non-invasive treatment strategy that directly targets the underlying pathology through light-sensitive cellular cascades. The Valeda Light Delivery System is successful in the treatment of AMD (cf. LIGHTSITE I & II). We here present an […]
Photobiomodulation—Underlying Mechanism and Clinical Applications
The purpose of this study is to explore the possibilities for the application of laser therapy in medicine and dentistry by analyzing lasers’ underlying mechanism of action on different cells, with a special focus on stem cells and mechanisms of repair. The interest in the application of laser therapy in medicine and dentistry has remarkably […]
Photobiomodulation Therapy for Age-Related Macular Degeneration and Diabetic Retinopathy: A Review
Abstract Purpose Photobiomodulation therapy (PBT) has emerged as a possible treatment for age-related macular degeneration (AMD) and diabetic retinopathy (DR). This review seeks to summarize the application of PBT in AMD and DR. Methods The National Clinical Trial (NCT) database and PubMed were queried using a literature search strategy and reviewed by the authors. Results […]
The Potential of Visible and Far-Red to Near-Infrared Light in Glaucoma Neuroprotection
Alternative treatment strategies are necessary to reduce the severity of glaucoma, a group of eye conditions that progressively damage the optic nerve and impair vision. The aim of this review is to gain insight into potentially exploitable molecular mechanisms to slow down the death of retinal ganglion cells (RGCs), a fundamental element in the pathophysiology […]
Energy Metabolism in the Inner Retina in Health and Glaucoma
Glaucoma, the leading cause of irreversible blindness, is a heterogeneous group of diseases characterized by progressive loss of retinal ganglion cells (RGCs) and their axons and leads to visual loss and blindness. Risk factors for the onset and progression of glaucoma include systemic and ocular factors such as older age, lower ocular perfusion pressure, and […]
Photobiomodulation for Hypertension and Alzheimer’s Disease
Although the cause(s) of Alzheimer’s disease in the majority of cases remains elusive, it has long been associated with hypertension. In animal models of the disease, hypertension has been shown to exacerbate Alzheimer-like pathology and behavior, while in humans, hypertension during mid-life increases the risk of developing the disease later in life. Unfortunately, once individuals […]
