Understanding Age-Related Macular Degeneration and Geographic Atrophy
Age-related macular degeneration is a major challenge in eye health, especially for older adults. This progressive condition affects the macula, the central part of the retina responsible for sharp vision. As retinal cells deteriorate, individuals experience gradual changes in their sight.
There are two main forms: dry and wet AMD. The dry form, which accounts for approximately 90% of cases, develops gradually over time. Unlike wet AMD, which has some treatments, dry AMD lacked effective options until recent breakthroughs.
The Challenge of Dry AMD and Central Vision Loss
Dry AMD involves the breakdown of light-sensitive cells in the macula. When these cells deteriorate, central vision becomes blurred.
Patients struggle with reading small print or recognising faces. These issues worsen as the condition progresses, making daily tasks such as cooking or driving more challenging.
The emotional toll extends beyond practical limits. Losing clear vision can significantly impact independence and quality of life, leading to feelings of isolation and frustration.
What is Geographic Atrophy?
Geographic atrophy is the advanced stage of dry AMD, where central macula cells die, creating expanding blind spots.
These cell loss areas appear as defined patches on retinal imaging. “Geographic” describes their map-like look, while “atrophy” indicates tissue wasting.
Approximately 5 million people globally have geographic atrophy, with no current treatment to halt or reverse degeneration, highlighting a significant need in eye care.
| Aspect | Dry AMD | Geographic Atrophy |
|---|---|---|
| Progression | Slow deterioration over the years | Advanced stage with rapid vision loss |
| Affected Area | Entire macula region | Specific patches in the central macula |
| Treatment Options | Limited preventive measures | No approved treatments available |
| Global Prevalence | Millions affected worldwide | Approximately 5 million people |
| Visual Outcome | Gradual central vision decline | Complete blindness in affected areas |
Clinical trial participants often have total central vision loss in one eye, relying solely on peripheral vision, which limits daily functioning.
New interventions aim to fill this treatment gap, offering hope for restoring vision and potentially transforming lives.

How the Revolutionary Wireless Retinal Implant Works
Modern ophthalmology has achieved what once seemed impossible through micro-engineering. The PRIMA System represents a sophisticated approach to addressing vision loss in dry AMD, combining advanced technology with biological integration, particularly beneficial for patients involved in the AMD clinical trial.
This innovative treatment works by creating prosthetic vision through a carefully orchestrated process. It bypasses damaged photoreceptor cells while preserving natural peripheral vision.
The Three Components of the PRIMA System
The complete system comprises three interconnected elements that work in harmony. Each component plays a crucial role in restoring functional sight for patients.
The wireless retinal implant measures just 2mm by 2mm and sits beneath the retina. This tiny chip contains photovoltaic cells that convert light into electrical signals.
Special augmented-reality glasses feature a built-in camera and digital projector. These capture visual information from the environment and process it through artificial intelligence algorithms.
A pocket processor acts as the system’s computational centre. It analyses visual data and determines what information to send to the retinal implant.
The Surgical Procedure: Implanting the Retinal Chip
Vitreoretinal surgeons perform the implantation in under two hours.
They start with a vitrectomy to remove the eye’s vitreous jelly, creating space for the micro-chip.
The device is inserted under the retinal tissue for optimal interaction with healthy cells.
Experts at Moorfields Eye Hospital state the procedure is safe, with most patients experiencing minimal discomfort.
From Infrared Light to Prosthetic Vision: The Process Explained
After a month, specialists activate the system. The glasses’ camera captures visual information.
AI algorithms process this data, focusing on key elements to enhance user experience.
The glasses project an infrared beam onto the retinal implant, eliminating the need for external cables.
Photovoltaic cells convert infrared light into impulses, stimulating retinal neurons.
The brain interprets these as visual patterns, allowing users to use their natural peripheral vision with artificial sight.
This approach significantly advances treatment for geographic atrophy, offering new possibilities for advanced macular degeneration.
Clinical Trial Results: Demonstrating Central Vision Restoration
European trials provide evidence for vision restoration in advanced macular degeneration, involving thirty-eight participants with severe impairment.
These individuals had vision worse than 20/320 before receiving the innovative treatment. The twelve-month investigation provided remarkable insights into the device’s effectiveness.
Key Outcomes from the European Study
Thirty-two participants completed the trial with outstanding results. Twenty-seven regained reading capability through the implanted system.
Visual acuity improved in twenty-six cases, with an average gain of five lines on eye charts.
One case showed twelve lines of improvement, a dramatic enhancement in sight.
Eighty-four percent regained the ability to read letters and numbers. Daily usage included reading books and labels.
| Measurement | Results | Significance |
|---|---|---|
| Participants completing the trial | 32 patients | 84% success rate |
| Reading ability restoration | 27 individuals | Life-changing impact |
| Average visual improvement | 5 chart lines | Clinically meaningful |
| Maximum improvement recorded | 12 chart lines | Exceptional outcome |
| Daily usage applications | Reading & navigation | Functional restoration |
