Photobiomodulation (PBM), previously referred to as low-level light therapy, has a 50-year history in medical research and has been investigated for treating a host of medical conditions. It is theorized that photons enter tissue and interact with enzyme cytochrome c oxidase located within mitochondria. Through an undefined mechanism, this is believed to increase cellular metabolism.

PHOTOBIOMODULATION THERAPY FOR LARGE SOFT DRUSEN AND DRUSENOID PIGMENT EPITHELIAL DETACHMENT IN AGE-RELATED MACULAR DEGENERATION: A Single-Center Prospective Pilot Study
Abstract Purpose: To evaluate visual acuity and morphologic changes after photobiomodulation (PBM) for patients affected with large soft drusen and/or drusenoid pigment epithelial detachment associated with dry age-related macular degeneration. Method: Twenty eyes with large soft drusen and/or drusenoid pigment epithelial detachment age-related macular degeneration were included and treated using the LumiThera Valeda Light Delivery System. All […]
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 […]
Photobiomodulation as a Treatment in Dry AMD
The development of innovative treatments for debilitating diseases such as age-related macular degeneration (AMD) is crucial to advance patient care and to reduce burdens on patients, caregivers, and physicians. The dry, or nonexudative, form of AMD affects approximately 85% to 90% of individuals with AMD, and, until now, there have been no approved treatments for […]
Five-year follow-up of low-level laser therapy (LLLT) in patients with age-related macular degeneration (AMD)
Abstract The objective of this study was to examine long-term effects of low-level laser therapy (LLLT) in patients with age-related macular degeneration (AMD). The research was implemented for a period of five years. For LLLT, a He-Ne Laser with continuous emission at 633 nm (0.1 mW/cm2) was used in patients with AMD of all stages […]
Photobiomodulation reduces drusen volume and improves visual acuity and contrast sensitivity in dry age-related macular degeneration
Abstract Purpose: To evaluate the efficacy of photobiomodulation (PBM) treatment for patients with dry age-related macular degeneration (AMD). Methods: Assessments on 42 eyes with dry AMD (age related eye disease study (AREDS) 2-4) were conducted. Multiwavelength light emitting diode (LED) light comprising of yellow (590 nm), red (670 nm) and near-infrared (790 nm) bandwidths was applied to […]
A DOUBLE-MASKED, RANDOMIZED, SHAM-CONTROLLED, SINGLE-CENTER STUDY WITH PHOTOBIOMODULATION FOR THE TREATMENT OF DRY AGE-RELATED MACULAR DEGENERATION
Abstract Purpose: The LIGHTSITE I study investigated the efficacy and safety of photobiomodulation (PBM) treatment in subjects with dry age-related macular degeneration. Methods: Thirty subjects (46 eyes) were treated with the Valeda Light Delivery System, wherein subjects underwent two series of treatments (3× per week for 3-4 weeks) over 1 year. Outcome measures included best-corrected visual acuity, […]
The Potential of Visible and Far-Red to Near-Infrared Light in Glaucoma Neuroprotection
Abstract 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 […]
The Potential Effects of Light Irradiance in Glaucoma and Photobiomodulation Therapy
Abstract Human vision is mediated by the retina, one of the most critical tissues in the central nervous system. Glaucoma is a complex retinal disease attributed to environmental, genetic, and stochastic factors, all of which contribute to its pathogenesis. Historically, glaucoma had been thought of primarily as a disease of the elderly; however, it is […]
The Beneficial Effects of Photobiomodulation to Reduce Intraocular Pressure in Primary Open-Angle Glaucoma
Abstract Purpose: The aim of this trail was to study the efficacy of photobiomodulation (PBM) treatment to reduce the intraocular pressure in subjects with primary open angle glaucoma disease. Methods: Twenty eyes suffering from open angle glaucoma with high IOP level were selected, examined and treated with Thera-RED light diode system. The subjects were divided into two […]
