Short-Term Results of Photobiomodulation Using Light-Emitting Diode Light of 670 nm in Eyes with Age-Related Macular Degeneration.

To evaluate the short-term result of retinal functional behavior in patients with dry age-related macular degeneration (AMD) corrected by photobiomodulation (PBM) with 670 nm light-emitting diode (LED) light. Ten patients with dry AMD underwent a treatment consisting of nine PBM sessions with LED light of 670 nm with two cycles of 50 mW/cm, producing 4 J/cm per dose in 88 sec. The studied eye was compared with the baseline (before therapy), and after nine PBM sessions, the following aspects were evaluated: best-corrected visual acuity (VA), retinal sensitivity, and characteristics of the correction area by the fundus automated perimetry using the Compass system.
