Photobiomodulation for Dry AMD: How Light Therapy Is Changing Retina Care

For patients with dry age-related macular degeneration (AMD), photobiomodulation (PBM), the first FDA-authorized non-invasive treatment for dry AMD, has emerged as a promising treatment. Understanding how PBM works and its benefits can help you and your retina specialist decide whether it's the right option for you.

What is Photobiomodulation?

PBM is a therapeutic technique that utilizes light therapy to stimulate cellular processes. In individuals with dry AMD, PBM aims to enhance mitochondrial function, which is crucial for retinal cell health. Mitochondria are responsible for producing the energy that powers our cells. When their function declines, as is frequently the case with age or degenerative conditions, vision problems can arise. PBM uses specific wavelengths of light that penetrate the eye's tissues, stimulating the mitochondria and providing retinal cells with a vital energy boost, enabling them to function more efficiently.

Since PBM relies on light for healing and reducing inflammation rather than drugs or invasive procedures, it typically results in fewer side effects and a quicker recovery time than more traditional AMD treatments, such as eye injections or surgery.

Who Could Benefit From PBM?

PBM was authorized by the FDA for the treatment of dry AMD based on the Lightsite III clinical trial, which showed a statistically significant visual benefit for the patients studied.
The criteria for participation in the Lightsite III trial were:

• Visual Acuity: Best-corrected visual acuity between 20/32 and 20/70.
• Retinal Characteristics: Presence of at least three medium drusen (yellow deposits under the retina), one or more large drusen, or non-central geographic atrophy.
• What Qualifies as an Exclusion: Patients do not qualify if they have wet AMD or geographic atrophy that involves the center of the macula.

While PBM is typically used for the kinds of patients that were enrolled in the Lightsite III study, it may also be appropriate for patients with other forms of dry AMD. It’s essential for patients to consult with a retina specialist who can evaluate their specific condition and discuss whether PBM might be a beneficial addition to their treatment plan.

Growing Research and Interest

Recent clinical studies have sparked significant interest in PBM technology. Research indicates that PBM may enhance visual function and offer a new treatment option for patients with dry AMD. While more research is needed to understand the long-term effects and efficacy of PBM fully, the initial results are promising, paving the way for further investigation.
