Red Light Therapy for Glaucoma: Science, Safety, and What the Research Shows outlines how photobiomodulation supports retinal ganglion cell health in glaucoma — neuroprotection mechanisms, peer-reviewed evidence, safety, and compatibility with prescribed care.
Photobiomodulation offers broad applicability for optic neuropathies through cytochrome c oxidase activation, with advantages over pharmacological interventions.

Red light has been shown to provide neuroprotective effects. Axotomizing the optic nerve initiates retinal ganglion cell (RGC) degeneration, and an early marker of this is dendritic pruning.
Mitochondrial dysfunction is common pathogenic feature across optic neuropathies; photobiomodulation offers enhancement without genetic manipulation.
670 nm preserved 40% more retinal ganglion cells following optic nerve crush injury through enhanced mitochondrial function and reduced oxidative stress.
To our knowledge, this is the first demonstration that 670-nm NIR light can reduce oxidative stress and improve function in the CNS following traumatic injury in vivo.
670 nm treatment preserved retinal ganglion cells and visual function in mitochondrial optic neuropathy model through enhanced mitochondrial enzyme activity.
