Age-Related Macular Degeneration (AMD): Symptoms, Types and Treatment
As a medical retina specialist, I see first-hand the profound impact that Age-Related Macular Degeneration (AMD) can have on a person’s life. AMD is the leading cause of sight loss in the UK, most commonly affecting people over the age of 50. Understanding this condition is crucial for protecting your sight.
At Clarity Healthcare, we believe that early awareness and prompt treatment are the most powerful tools we have for managing Age-Related Macular Degeneration.
What Is Age-Related Macular Degeneration?
Age-Related Macular Degeneration is an eye condition that damages the macula, causing blurred or distorted central vision while side vision is usually unaffected.
The macula is a small area at the centre of the retina, the light-sensitive tissue at the back of the eye. Although tiny, it is responsible for your sharp, detailed central vision, the precision you rely on for reading, recognising faces and driving.
When AMD damages the macula, your peripheral (side) vision typically remains intact, so AMD rarely causes complete blindness. However, the loss of central detail can make everyday activities increasingly difficult as the condition progresses.
What Are the Symptoms of AMD?
Common symptoms of AMD include:
- Blurred or distorted central vision
- Straight lines appearing wavy or bent
- A dark or blank spot in the centre of your vision
- Difficulty reading or recognising faces
- Colours appearing less vivid
Symptoms may develop gradually or appear suddenly. A sudden change in your central vision should always be assessed promptly.
What Are the Two Types of AMD?
There are two main types of Age-Related Macular Degeneration: dry AMD and wet AMD.
Dry AMD
Dry AMD is the most common form. It develops slowly over many years as cells in the macula are gradually damaged, often alongside a build-up of yellow deposits called drusen. There is currently no treatment that can reverse dry AMD, but stopping smoking, eating a healthy diet and, for some people, taking specific vitamin supplements may help to slow its progression.
Wet AMD
Wet AMD is less common but more serious. It occurs when abnormal blood vessels grow beneath the macula and leak fluid or blood, which can cause rapid and severe loss of central vision. Although wet AMD can develop quickly, it is often treatable, especially when diagnosed early. Dry AMD can sometimes progress to wet AMD, which is why monitoring your vision is so important.
How Is Wet AMD Treated?
Wet AMD is usually treated with intravitreal injections of anti-VEGF medication, which stop abnormal blood vessels from growing and leaking.
For patients with wet AMD, timely treatment is key to stabilising, and in some cases improving, vision. As a medical retina specialist, my focus is on delivering modern, evidence-based therapies, primarily through intravitreal injections.
What Is an Intravitreal Injection?
An intravitreal injection delivers medication directly into the vitreous, the clear gel that fills the inside of the eye. The medications used are known as anti-VEGF agents (such as Vabysmo, Eylea or Ximluci), and they work by blocking the growth and leakage of abnormal blood vessels.
The idea of an injection in the eye can sound daunting, but the procedure is quick and carefully managed, and the eye is numbed with anaesthetic drops beforehand. Treatment usually needs to be repeated over months or years to maintain its effect. Anti-VEGF therapy has transformed the management of wet AMD, helping many patients keep useful vision that would otherwise have been lost.
How Can You Protect Your Sight From AMD?
The key to preventing AMD from progressing, or living well with it, is a combination of awareness and action:
- Have regular eye examinations. Early diagnosis is essential, so make sure you have regular eye tests, especially if you are over 50.
- Monitor your vision at home. Check each eye separately and watch for sudden changes, such as straight lines looking wavy or a blank spot in your central vision. If you notice a change, seek medical advice promptly.
- Reduce your risk factors. Smoking is one of the biggest risk factors for AMD, so stopping smoking is one of the most effective steps you can take. A diet rich in dark, leafy green vegetables and oily fish, combined with regular exercise, can also play a valuable supporting role.
A Personalised Approach to AMD Care
I take a personalised approach with every patient, taking time to understand your individual medical history before discussing management options. Where appropriate, this may include holistic care alongside medical treatment.
Frequently Asked Questions About AMD
Can Age-Related Macular Degeneration cause total blindness?
AMD rarely causes total blindness because it affects central vision while peripheral (side) vision is usually preserved. However, advanced AMD can significantly affect reading, driving and recognising faces.
Is AMD painful?
No. AMD is not usually painful, which is why regular eye examinations and monitoring for changes in your vision are so important.
Do eye injections for wet AMD hurt?
Most patients feel only brief pressure or mild discomfort. The eye is numbed with anaesthetic drops before the injection, and the procedure itself takes only a few minutes.
Can dry AMD turn into wet AMD?
Yes, dry AMD can progress to wet AMD in some people. If you have dry AMD and notice a sudden change in your central vision, seek medical advice promptly.
Support and Resources for People With AMD
If you or a family member has been diagnosed with macular degeneration, support is available. The Macular Society and the RNIB provide excellent, up-to-date information on the condition, diet, local support groups and current research.
