LLLT stabilized visual fields and improved subjective visual function in retinitis pigmentosa patients without adverse effects, expanding clinical evidence.
Near-infrared 670 nm light significantly increased ATP production in aging retinal tissue, providing quantitative evidence for mitochondrial recharging.
After four initial treatments of LLLT, visual acuity increased to 20/20 in each eye. Visual fields normalized except for a mid-peripheral absolute concentric scotoma. Five years after discontinuation of LLLT, a relapse was observed. LLLT was repeated (another four treatments) and restored the initial success.
This case report describes the effects of low-level laser therapy (LLLT) in retinitis pigmentosa (RP). 670 nm LED superior to 830 nm for retinal/optic nerve protection, reducing reactive oxygen species and oxidative DNA damage.
670 nm preserved photoreceptor function and slowed degeneration in P23H retinitis pigmentosa model through mitochondrial redox state preservation.
670 nm reduced complement C3 deposition and pathway activation in retinal degeneration, attenuating inflammation and enhancing photoreceptor preservation.
670 nm treatment preserved retinal ganglion cells and visual function in mitochondrial optic neuropathy model through enhanced mitochondrial enzyme activity.
670 nm pretreatment preserved photoreceptor function and reduced cell death in light-induced retinal degeneration through mitochondrial enhancement.
