Overview
The goal of this clinical trial is to evaluate effects of consecutive Yellow and Red Light Emitting Diode photobiomodulation in dry age-related macular degeneration (AMD). The main questions it aims to answer are:
- Is Yellow and Red Light Emitting Diode photobiomodulation effective in decreasing drusen volume in patients affected by dry AMD?
- Does Yellow and Red Light Emitting Diode photobiomodulation increase visual acuity and contrast sensitivity in patients affected by dry AMD? Participants will be randomly assigned to a treatment or a sham group.
Treatment consists in two cycles with two phases each:
- 1st phase: 300 seconds of continuous Yellow light with eyes closed + 60 seconds of pulsed Yellow light with eyes opened;
- 2d phase: 300 seconds of continuous Red light with eyes closed + 60 seconds of pulsed Red light with eyes opened.
Cycle 1 consists of 8 sessions (two PBM per week for 4 weeks) and cycle 2 consists of 6 sessions (two PBM per week for 3 weeks).
Researchers will compare patients in the treatment group to those in the sham group to evaluate differences in objective signs and subjective symptoms of dry AMD.
