Study Summary

This trial is a continuation of a previous study on the use of photobiomodulation in people with dry age-related macular degeneration. It is open to participants from multiple centers.

Who is the study for?
This trial is for individuals who completed the CSP005 study, have dry age-related macular degeneration (AMD) with certain vision scores, and can follow the study requirements. They must not have other eye diseases that affect vision or a history of light sensitivity, recent invasive eye surgery, serious illnesses, cancer in the past 5 years (with exceptions), or substance abuse.Check my eligibility
What is being tested?
The LIGHTSITEIIIB trial tests ongoing use of photobiomodulation (PBM) using the Valeda Light Delivery System on people with dry AMD who participated in a previous related study. It's an open-label extension meaning participants and researchers know what treatment is being used.See study design
What are the potential side effects?
Potential side effects are not explicitly listed but may include discomfort due to light exposure from PBM therapy. Participants should not have known light sensitivity or skin conditions exacerbated by light.
