Light-Based Hope in Macular Degeneration: Valeda (Photobiomodulation) Therapy for Dry AMD

Macular degeneration, medically known as age-related macular degeneration (AMD), is a progressive eye condition that affects the macula, the central part of the retina responsible for sharp and detailed vision. As this area deteriorates over time, patients may experience blurred central vision, difficulty reading, and challenges in recognizing faces.

AMD is most commonly seen in individuals over the age of 50 and can significantly impact quality of life in advanced stages.

There are two main types:

1. Dry AMD – The most common form, accounting for approximately 85–90% of cases
2. Wet AMD – A less common but more aggressive form with clearer treatment pathways

For many years, dry AMD posed a major challenge due to the lack of effective treatment options. However, emerging technologies are now reshaping this landscape.

Why Has Dry AMD Been Difficult to Treat?

The primary issue in dry AMD lies in the gradual deterioration of retinal cells. This includes:

1. Loss of function in retinal cells
2. Degeneration of photoreceptor cells
3. Reduced cellular energy production due to mitochondrial dysfunction

Although the disease progresses slowly, the damage is often irreversible. Traditionally, management has been limited to:

1. Nutritional supplements (AREDS formulations)
2. Lifestyle modifications
3. Regular monitoring

These approaches help slow progression but do not actively restore retinal function.

What Is Valeda (Photobiomodulation) Therapy?

The Valeda Light Delivery System is a next-generation treatment developed for dry AMD. It is based on a technology called photobiomodulation (PBM).

This innovative approach uses specific wavelengths of light to stimulate biological activity within retinal cells.

What Is Photobiomodulation?

Photobiomodulation is a non-invasive therapy that involves applying low-level light at specific wavelengths to influence cellular activity.

In simple terms:

Light energy stimulates cells and helps them function more efficiently.

How Does Valeda Therapy Work?

The Valeda system delivers light at three different wavelengths:

1. 590 nm (yellow light)
2. 660 nm (red light)
3. 850 nm (near-infrared light)

These wavelengths target retinal cells and:

1. Stimulate mitochondria (the cell’s energy center)
2. Increase ATP production
3. Reduce inflammation and oxidative stress
4. Support cell survival and function

Result:

Improved retinal performance and potential enhancement in visual function.

Advantages of Valeda Therapy

Unlike traditional approaches, Valeda offers a patient-friendly and non-invasive solution.

Key benefits include:

1. No surgery required
2. Painless procedure
3. Minimal risk of side effects
4. Quick sessions in a clinical setting
5. Immediate return to daily activities

These features make it particularly attractive for international patients seeking efficient and comfortable treatment options.

What Does the Treatment Process Look Like?

Valeda therapy is typically administered in structured treatment cycles.

A standard protocol includes:

1. Multiple sessions per week
2. Each session lasting approximately 5–10 minutes
3. Treatment cycles spanning several weeks

During the session, the patient sits comfortably in front of the device and is exposed to controlled light therapy. The procedure is completely painless.

Who Is a Suitable Candidate?

Valeda therapy is especially suitable for:

1. Patients with dry AMD
2. Individuals in early to intermediate stages
3. Those experiencing a decline in visual quality

However, not every patient is a candidate. A comprehensive retinal examination and imaging assessment are essential before treatment planning.

What Do Clinical Studies Show?

Clinical studies on photobiomodulation and the Valeda system have demonstrated promising results, including:

1. Improvements in visual acuity
2. Enhanced contrast sensitivity
3. Support for retinal function

Notably, the LIGHTSITE studies provide strong clinical evidence supporting the effectiveness of this therapy.

Valeda Therapy in Health Tourism

Eye treatments are a rapidly growing segment in health tourism, and advanced technologies like Valeda are becoming a key driver for international patient flow.

Why patients choose Turkey:

1. International-standard ophthalmology clinics
2. Experienced retinal specialists
3. More accessible costs compared to Europe
4. Short, travel-friendly treatment protocols

This allows patients to combine treatment with travel, creating a seamless healthcare experience.

What to Expect After Treatment

Valeda therapy is not an instant cure. However, patients may observe gradual improvements such as:

1. Better visual clarity
2. Improved reading ability
3. Enhanced performance in daily activities

The primary goal is to slow disease progression and preserve existing vision.

Why Early Diagnosis Matters

Early detection is critical in macular degeneration.

When treatment begins at an early stage:

1. Outcomes are more favorable
2. Cell loss is minimized
3. Vision can be better preserved

Delaying intervention reduces the potential benefits of advanced therapies like Valeda.

Conclusion: A New Era Powered by Light

For many years, dry AMD was considered a condition that could only be monitored rather than actively treated.

Today, with innovations like Valeda photobiomodulation therapy:

1. Active treatment options are becoming available
2. Patients have new hope for preserving vision
3. Health tourism is entering a new, technology-driven phase

Light-based therapies are not just an alternative—they represent a shift toward regenerative and supportive eye care.
