Hi . That must be incredibly disappointing. I'm not personally familiar with the course of treatment, but several in the community have tried red light therapy, using the Valeda system. Here is a forum post in which a member notes improvement after nine sessions: https://maculardegeneration.net/forums/valeda-light-therapy. Hopefully, others will chim in with their own experiences. What has your doctor said? - Lori (Team Member)
