Condition focus: Retinal Diseases & Clinical Applications
As photobiomodulation clinical applications expanded across ophthalmology, comprehensive assessment of efficacy, safety, and practical implementation became critical for guiding evidence-based practice. This review examined photobiomodulation applications for retinal diseases with emphasis on clinical outcomes, treatment protocols, and patient selection. The analysis synthesized evidence from clinical trials and case series across age-related macular degeneration, diabetic retinopathy, retinitis pigmentosa, and other retinal conditions to evaluate therapeutic potential and identify optimal applications.
The review documented consistent visual function improvements across retinal diseases, with particularly robust evidence in dry AMD where multiple studies demonstrated stabilized or improved visual acuity and contrast sensitivity. Diabetic macular edema trials showed anatomic improvements with reduced central subfield thickness alongside functional gains. Inherited retinal degenerations exhibited disease stabilization and subjective visual improvements in treatment groups. Safety profiles were uniformly favorable with no significant adverse effects reported across studies. However, the review identified substantial protocol variability including wavelength selection, treatment duration, energy density, and frequency, emphasizing the need for standardization. Patient selection criteria and optimal disease stage for intervention remained incompletely defined. The analysis supported photobiomodulation’s clinical utility while highlighting critical gaps requiring systematic investigation to optimize therapeutic implementation.
