Study of Photobiomodulation to Treat Dry Age-Related Macular Degeneration — LIGHTSITE1  

Age Related Macular Degeneration Clinical Trial

Official title: A Double-Masked, Randomized, Sham-Controlled, Parallel Group, Single-Center Study to Assess the Safety and Efficacy of Photobiomodulation in Subjects With Dry Age-Related Macular Degeneration

Status Completed

Clinical Trial Summary

The purpose of this research study is to determine if photobiomodulation is an effective treatment of Dry Age-Related Macular Degeneration (AMD) and vision loss associated with the disease.

Clinical Trial Description

The LumiThera LT 300® Light Delivery System is a stationary desktop instrument used to emit energy in the visible and near infrared spectrum. The LT-300® is designed for the ophthalmologist to use in the treatment of the eye with photobiomodulation (PBM), a process by which cellular mechanisms are induced by light. PBM is being utilized in many indications, such as wound healing, soft tissue injuries, joint pain, myofascial pain, nerve injuries, muscle fatigue for temporary improvement in blood flow and reduction in inflammation. The mechanism of PBM at the cellular level has been ascribed to the activation of mitochondrial respiratory chain components resulting in stabilization of metabolic function and initiation of a signaling cascade, which promotes cellular proliferation and cytoprotection. The LT-300® will provide a preset treatment of PBM to the subject's eye and retinal tissue through the open and closed eyelid.

Approximately 30 subjects meeting the eligibility requirements of the study will be randomly assigned in a 1:1 ratio to receive standard of care treatment for Dry AMD plus PBM treatment with the LT-300 system, or standard of care treatment for Dry AMD plus Sham treatment with the LT-300 system. Subjects randomized to each group will receive two 3-week treatment sessions (9 treatments per session) and follow-up visits extending to one year. The primary objective of the study is to evaluate the safety and efficacy of PBM with respect to visual and anatomical outcomes of subjects with Dry AMD. ;
