Condition focus: Retinal Injury & Disease – Translational Overview
As photobiomodulation research progressed from cellular studies to clinical applications, comprehensive integration of mechanistic understanding with therapeutic outcomes became essential for guiding clinical translation. This review synthesized evidence from the authors’ pioneering work on near-infrared photobiomodulation across diverse retinal injury and disease models, bridging bench-to-bedside applications. The analysis integrated findings from methanol-induced retinal toxicity, light-induced retinal degeneration, inherited retinal dystrophies, diabetic retinopathy, and age-related macular degeneration to identify common therapeutic mechanisms and optimal treatment parameters.
The review established that near-infrared light (particularly 670 nm) consistently protects retinal cells through cytochrome c oxidase activation, leading to enhanced ATP production, reduced oxidative stress, decreased inflammation, and improved cellular survival across diverse pathological conditions. Dose-response relationships demonstrated therapeutic windows with optimal effects at specific energy densities, while timing studies revealed both preventive and rescue treatment efficacy. The mechanistic framework showed that photobiomodulation addresses fundamental metabolic dysfunction underlying varied retinal pathologies rather than disease-specific mechanisms, explaining therapeutic breadth. Clinical translation challenges were identified including treatment protocol standardization, patient selection criteria, and outcome measure optimization. The analysis provided a comprehensive translational roadmap supporting photobiomodulation’s progression from experimental therapy to clinical practice.
