Age-Related & Acquired Retinal Conditions

Age-Related Macular Degeneration (AMD)

One of the leading causes of vision loss among older adults worldwide. It affects the macula, the central part of the retina responsible for sharp, detailed vision used for reading, recognising faces, driving, and performing many everyday tasks.

Understanding Age-Related Macular Degeneration

Age-Related Macular Degeneration (AMD) is one of the leading causes of vision loss among older adults worldwide. It affects the macula, the central part of the retina responsible for sharp, detailed vision used for reading, recognising faces, driving, and performing many everyday tasks.

AMD develops gradually as the retina changes with age. While it does not usually cause complete blindness because peripheral (side) vision is often preserved, it can significantly affect central vision and a person’s ability to live independently.

The condition exists in two main forms:

  • Dry AMD, the most common form, which develops gradually over time.
  • Wet AMD, a less common but more aggressive form that can cause rapid vision loss if left untreated.

An advanced stage of Dry AMD is known as Geographic Atrophy (GA), where areas of retinal cells progressively degenerate.

Significant advances in retinal research have transformed the diagnosis and management of AMD. Effective treatments are now available for Wet AMD, while new therapies for Geographic Atrophy are providing hope for slowing disease progression.

Retina International works with patient organisations, clinicians, researchers, policymakers, and industry partners worldwide to improve awareness of AMD, promote equitable access to diagnosis and treatment, and ensure that the voices of people living with macular disease help shape research and healthcare decisions.

What is Age-Related Macular Degeneration?

Age-Related Macular Degeneration is a progressive retinal disease that affects the macula, the small central area of the retina responsible for high-resolution central vision.

The macula enables us to:

  • Read text
  • Recognise faces
  • Drive safely
  • See fine detail
  • Distinguish colours
  • Perform close-up tasks

As AMD progresses, damage to the macula causes central vision to become blurred or distorted. Peripheral vision usually remains unaffected, meaning people rarely become completely blind from AMD.

There are two main forms of the disease:

Dry AMD

Dry AMD accounts for approximately 80–90% of all AMD cases. It develops gradually as retinal cells become damaged and deposits known as drusen accumulate beneath the retina.

Over time, some people with Dry AMD develop Geographic Atrophy, an advanced stage characterised by irreversible loss of retinal cells.

Wet AMD

Wet AMD develops when abnormal blood vessels grow beneath the retina. These fragile vessels leak blood and fluid, damaging the macula and causing rapid central vision loss if not treated promptly.

Although Wet AMD affects fewer people than Dry AMD, it is responsible for the majority of severe vision loss associated with AMD.

80–90%

Dry AMD accounts for approximately 80–90% of all AMD cases.

Over 50

AMD most commonly affects people over the age of 50, with risk increasing as people get older.

2 main forms

AMD occurs in Dry and Wet forms, with Wet AMD causing faster and often more severe vision loss.

Symptoms

How AMD can affect vision

Symptoms vary depending on the stage and type of AMD. Early AMD may cause few or no noticeable symptoms. As the disease progresses, people may experience:
Blurred central vision

Reading and recognising faces may become increasingly difficult.

Distorted vision (metamorphopsia)

Straight lines may appear bent or wavy.

Difficulty seeing fine detail

Tasks requiring precision, such as sewing or reading small print, may become challenging.

Reduced contrast sensitivity

Objects may appear less distinct from their background.

Dark or blank areas in central vision

Advanced AMD may cause blind spots within the central visual field.

Difficulty adapting to changes in light

People may require more time to adjust between bright and dim environments.

Symptoms of Wet AMD often develop suddenly and require urgent assessment by an eye care professional.

Diagnosis

Identifying AMD

Early diagnosis is essential for preserving vision, particularly in Wet AMD. Diagnosis may include:
Comprehensive eye examination

An ophthalmologist or optometrist examines the retina for signs of AMD.

Optical Coherence Tomography (OCT)

OCT provides detailed cross-sectional images of the retina, allowing clinicians to identify fluid, retinal swelling, or areas of degeneration.

Fundus photography

Retinal photographs document changes over time.

Fundus autofluorescence (FAF)

FAF imaging helps identify retinal pigment epithelium damage, particularly in Geographic Atrophy.

Fluorescein angiography

This imaging test may be used to identify abnormal blood vessels associated with Wet AMD.

Amsler Grid

An Amsler Grid can help detect distortion or changes in central vision and is commonly used for home monitoring.

Treatment & Management

Supporting independence

Treatment depends on the type and stage of AMD.
Dry AMD

There is currently no cure for Dry AMD.

Management focuses on:

  • Regular monitoring
  • Healthy lifestyle choices
  • Smoking cessation
  • Nutritional support where appropriate
  • Low vision rehabilitation

Some people may benefit from nutritional supplements based on clinical guidelines.

Geographic Atrophy

Recently approved therapies can help slow the progression of Geographic Atrophy in some individuals.

Researchers continue to investigate additional treatments that may preserve retinal cells.

Wet AMD

Wet AMD is commonly treated using anti-VEGF medicines, delivered through injections into the eye.

These medicines reduce abnormal blood vessel growth and leakage, helping preserve vision and, in some cases, improve visual outcomes.

Early diagnosis and ongoing treatment are essential for achieving the best possible results.

Vision rehabilitation

Low vision services and assistive technologies can help people maintain independence and continue everyday activities.

Living With AMD

Supporting independence, and participation

Living with AMD often involves adapting to gradual changes in central vision.

Many people continue to lead active and independent lives with appropriate treatment, support, and rehabilitation.

Support strategies may include:

  • Low vision services
  • Magnifiers and assistive technology
  • Accessible digital devices
  • Orientation and mobility support
  • Emotional wellbeing services
  • Peer support groups

Regular eye examinations and adherence to treatment plans are important for maintaining vision and quality of life.

Patient organisations also provide valuable education, practical advice, and opportunities to connect with others affected by AMD.

Take the Next Step

Age-Related Macular Degeneration affects millions of people worldwide, but advances in research, earlier diagnosis, and improved treatments are changing the outlook for many individuals.

By working together across the global retinal community, Retina International is helping accelerate innovation, strengthen patient advocacy, and improve outcomes for people living with AMD.
