Multiwavelength Photobiomodulation Improves Multiple Aspects of Visual Function in Early-Stage Dry Age-Related Macular Degeneration

PBM treatment of patients with earlier stage dry AMD showed improvements on multiple visual outcome measures and no adverse effects. Earlier stage AMD populations may not show robust magnitude effects as their starting vision does not show serious deficits, however; as a result of the degenerative and progressive nature of the disease, repeat treatment and continued monitoring of these outcomes are of interest. These beneficial effects were improved with repeated PBM treatment series.
