What is Dry Age-Related Macular Degeneration (AMD)?
Dry Age-Related Macular Degeneration (AMD) affects over 200 million people worldwide and is the leading cause of vision loss in adults over 60. This progressive eye disease targets the macula—the central part of your retina responsible for sharp, detailed vision needed for reading, driving, and recognising faces.
Common Dry AMD Symptoms:
- Central vision loss or blind spots
- Difficulty reading small print or recognising faces
- Straight lines appearing wavy (metamorphopsia)
- Colours appearing faded or less vibrant
- Need for brighter lighting for daily tasks
- Slow adaptation from light to dark environments
Geographic atrophy (GA) represents the advanced stage of dry AMD, where retinal cells die, creating expanding areas of vision loss.
Breakthrough: FDA-Approved Photobiomodulation (light therapy) Therapy for Dry AMD
What is Photobiomodulation Therapy?
Photobiomodulation (light therapy) therapy is a revolutionary non-invasive treatment that uses calibrated wavelengths of red, yellow, and near-infrared light to stimulate healing in retinal cells.
The most widely studied and commercially available system is the Valeda™ Light Delivery System, developed by LumiThera. This device was used in the landmark LIGHTSITE III clinical trial and is now available at Harley Vision.
Key Benefits of photobiomodulation Therapy:
- ✅ No injections or surgery required
- ✅ Painless and comfortable treatment
- ✅ No recovery time needed
- ✅ Clinically proven to improve vision
- ✅ Slows disease progression
How Does Photobiomodulation Work for Macular Degeneration?
Photobiomodulation light therapy targets the underlying cellular dysfunction in dry AMD through three core mechanisms:
- Mitochondrial Enhancement
- Boosts cellular energy production in retinal cells
- Improves metabolic efficiency of photoreceptors
- Enhances cellular repair mechanisms
- Anti-Inflammatory Action
- Reduces chronic inflammation in the macula
- Decreases oxidative stress damage
- Protects against free radical damage
- Cellular Regeneration
- Stimulates natural healing processes
- Promotes healthy cell metabolism
- Supports retinal tissue preservation
Clinical Evidence: LIGHTSITE III Trial Results
The LIGHTSITE III clinical trial—a rigorous, multicentre, sham-controlled study—demonstrated unprecedented results for non-invasive dry AMD treatment:
Vision Improvement:
- Average gain of 5.6 ETDRS letters (~1 line of vision)
- Significant improvement in visual acuity vs. control group

Treatment Overview
Q: What exactly is photobiomodulation therapy? A: Photobiomodulation (PBM) is a revolutionary, non-invasive light-based treatment that uses precisely calibrated red, yellow, and near-infrared wavelengths to stimulate cellular repair in the retina. The FDA-approved Valeda™ system delivers therapeutic light through a comfortable headset, targeting mitochondrial dysfunction and inflammation that drive dry AMD progression. Unlike traditional treatments, PBM actively promotes cellular healing at the molecular level.
Q: How does photobiomodulation differ from injections or vitamin supplements? A: PBM offers a unique advantage over existing treatments. While anti-VEGF injections are invasive and only treat wet AMD, photobiomodulation is completely painless and specifically targets dry AMD. Unlike vitamin supplements that provide passive nutritional support, PBM actively stimulates cellular function, improves energy production, and has been clinically proven to preserve and even improve vision. It’s the first therapy to show both vision improvement and disease slowing in dry AMD.
Q: Is this the same as laser treatment? A: No, photobiomodulation uses low-level therapeutic light that’s completely different from destructive laser treatments. PBM light is gentle, healing, and stimulates natural cellular processes without causing any tissue damage. There’s no heat, no burning, and no risk of complications associated with traditional laser procedures.
Eligibility & Effectiveness
Q: Who is an ideal candidate for photobiomodulation therapy? A: Ideal candidates include patients with intermediate dry AMD who haven’t yet developed central geographic atrophy (GA). Those experiencing early vision changes, difficulty with reading or driving, but who aren’t candidates for wet AMD injections typically benefit most. Patients with stable dry AMD, good overall eye health, and realistic expectations see the best outcomes. A comprehensive retinal assessment with OCT imaging confirms suitability.
Q: Can I have PBM therapy if I already have geographic atrophy? A: PBM therapy is most effective before central geographic atrophy develops. Once significant central GA is present, the treatment may be less beneficial since the retinal cells in those areas have already been lost. However, patients with peripheral GA or early central changes may still be candidates. Each case requires individual assessment by our retinal specialists.
Q: How quickly will I notice vision improvements? A: Most patients begin experiencing subtle improvements in visual clarity, reading comfort, or light sensitivity within 4-8 weeks of starting treatment. Optimal results typically develop over 3-6 months, with some patients reporting continued improvement for up to a year. The vision gains are gradual but meaningful, often allowing patients to return to activities they had difficulty with before treatment.
Q: What specific vision improvements can I expect? A: Clinical studies show patients gain an average of 5.6 letters on eye charts (approximately one line of vision). In practical terms, this often translates to improved reading ability, better facial recognition, enhanced color perception, and reduced difficulty with daily tasks. Many patients report less dependence on magnification aids and improved confidence with activities like driving.
Q: Is photobiomodulation therapy completely safe? A: Yes, PBM therapy has an exceptional safety profile. The LIGHTSITE III clinical trial reported no significant adverse effects, and the treatment has been used safely in thousands of patients worldwide. The light wavelengths used are well within safe parameters, and the non-invasive nature eliminates risks associated with injections or surgery. It’s suitable for patients who may not be candidates for more invasive procedures.
Q: How long do the treatment benefits last? A: The vision improvements and disease-slowing effects typically last 4-6 months after the initial treatment series. This is why we recommend maintenance treatments every 4-6 months. Some patients may experience longer-lasting benefits, while others may need more frequent maintenance. Regular monitoring with OCT imaging helps determine the optimal treatment schedule for each individual.
Treatment Experience & Logistics
Q: What happens during a photobiomodulation session? A: Each session is remarkably comfortable and relaxing. You’ll be seated in a reclining chair and fitted with the Valeda™ headset, which resembles comfortable gaming headphones. The device delivers gentle, invisible light to your eyes for 10-20 minutes while you simply relax. Many patients describe it as meditative, with some even falling asleep during treatment. There’s no discomfort, no eye drops needed, and no recovery time required.
Q: How many treatment sessions will I need? A: The standard initial protocol involves 2-3 sessions per week for 4 weeks (8-12 total sessions). After this initial series, patients typically begin maintenance treatments every 4-6 months based on their response and disease progression. Some patients may benefit from slightly different schedules, which our specialists determine based on OCT monitoring and clinical response.
Q: Will I need someone to drive me home after treatment? A: No, you can safely drive yourself to and from appointments. PBM therapy doesn’t cause any immediate vision changes, eye dilation, or discomfort that would affect your ability to drive. Most patients resume all normal activities immediately after each session.
Q: How should I prepare for treatment sessions? A: No special preparation is required. You can eat normally, take your regular medications, and maintain your usual routine. We recommend wearing comfortable clothing and bringing something to read for the waiting area. If you wear contact lenses, you may want to bring your glasses as an alternative, though contacts don’t interfere with treatment.
Q: Can I continue my normal activities during the treatment period? A: Absolutely. One of the major advantages of PBM therapy is that it doesn’t disrupt your daily life. You can work, exercise, drive, and engage in all your usual activities throughout the treatment period. There are no activity restrictions or lifestyle modifications required.
Financial & Insurance Considerations
Q: Is photobiomodulation therapy available on the NHS? A: Currently, PBM therapy is only available as a private treatment at specialized centers like Harley Vision. While the NHS doesn’t yet cover this treatment, the evidence base is growing rapidly, and future coverage may be considered as more data becomes available and cost-effectiveness is established.
Q: Will my private health insurance cover the treatment? A: Coverage varies by insurance provider and policy. Some private health insurers are beginning to recognize PBM therapy and may provide partial or full reimbursement, especially given its proven clinical benefits and safety profile. We’re experienced in working with insurance companies and can provide all necessary documentation, pre-authorization requests, and clinical justification to support your claim.
Q: What is the cost of photobiomodulation therapy? A: Treatment costs vary based on the number of sessions required and individual treatment plans. We provide transparent pricing during your consultation and offer flexible payment options to make treatment accessible. Many patients find the investment worthwhile given the potential to preserve independence and quality of life that comes with maintained vision.
Q: Are there financing options available? A: Yes, we offer various financing options to help make treatment accessible. These include payment plans that spread the cost over several months, as well as partnerships with medical financing companies. We believe that financial constraints shouldn’t prevent access to sight-saving treatment and work with each patient to find a suitable arrangement.
Integration with Other Treatments
Q: Can photobiomodulation be used alongside AREDS2 vitamins? A: Yes, PBM therapy works excellently in combination with AREDS2 supplements. The vitamins provide nutritional support for retinal health, while photobiomodulation actively stimulates cellular function. This combination approach offers comprehensive dry AMD management, addressing both nutritional deficiencies and cellular dysfunction.
Q: What if I develop wet AMD while receiving PBM treatment? A: If wet AMD develops, you would need anti-VEGF injections to treat the wet component. However, PBM therapy can often be continued alongside wet AMD treatment to continue supporting the areas of dry AMD. Our specialists coordinate comprehensive care to address both conditions effectively.
Q: Can I have PBM therapy if I’m taking blood-thinning medications? A: Yes, blood-thinning medications don’t interfere with PBM therapy since it’s completely non-invasive. Unlike injections, which may require temporary discontinuation of blood thinners, photobiomodulation can be safely performed regardless of your medication regimen.
Q: Are there any medications that interfere with PBM therapy? A: Currently, there are no known medications that interfere with photobiomodulation therapy. The treatment doesn’t interact with systemic medications, eye drops, or supplements. However, we always review your complete medication list during consultation to ensure comprehensive care coordination.
Long-term Outcomes & Follow-up
Q: How will we monitor my progress during treatment? A: We use advanced diagnostic imaging, including OCT scans, to monitor changes in your retinal structure and track treatment response. Visual acuity testing, contrast sensitivity measurements, and quality of life assessments help us evaluate functional improvements. Regular monitoring typically occurs every 3-4 months, with more frequent assessments during the initial treatment period.
Q: What happens if the treatment doesn’t work for me? A: While clinical trials show high success rates, individual responses can vary. If you don’t respond to the initial treatment series, we’ll thoroughly evaluate your case and discuss alternative approaches. Sometimes adjusting the treatment protocol or addressing other factors affecting AMD progression can improve outcomes. Our commitment is to work with you to find the most effective management strategy for your specific situation.
Q: Can the treatment be repeated if my vision declines again? A: Yes, PBM therapy can be safely repeated multiple times. Many patients undergo regular maintenance treatments every 4-6 months for ongoing vision preservation. If vision declines between maintenance sessions, additional treatment courses can be administered. The safety profile allows for long-term, repeated use as needed to maintain optimal outcomes.
