What Is The Best Treatment For Macular Degeneration? By Dr Rupal Morjaria, Consultant Ophthalmologist

If you have been diagnosed with macular degeneration, one of the first questions you may understandably ask is:

“What is the best treatment for macular degeneration?”

You may be worried about your eyesight, unsure whether the condition will get worse, or confused by the different treatments you have heard about.

The answer depends largely on which type of macular degeneration you have.

Age related macular degeneration (AMD) can broadly be divided into two types: dry AMD and wet AMD.

They affect the same central part of the retina, but they behave differently and require different approaches to treatment.

As a Consultant Ophthalmologist and Medical Retina Specialist, I regularly assess and treat patients with macular degeneration.The first step is understanding which type you have, how it is affecting your vision and what can be done to protect your sight.

The short answer

There is no single treatment that is best for everyone with macular degeneration.

For wet age related macular degeneration (wet AMD), the main treatment is usually injections of medicine into the eye. These are known as anti vascular endothelial growth factor injections (anti VEGF injections).

These medicines help control the abnormal blood vessels that can leak fluid or blood beneath the retina.

For dry age related macular degeneration (dry AMD), treatment is different. There is currently no routine treatment that can reverse the condition. Instead, the focus is on monitoring, reducing relevant risk factors, supporting your vision and recognising any significant changes as early as possible.

Understanding whether you have dry or wet AMD is therefore essential when considering the best treatment for your eyes.

What is macular degeneration?

The retina is the light sensitive layer of tissue at the back of the eye.

At the centre of the retina is a small area called the macula. This is responsible for the detailed central vision you use when reading, recognising faces, driving and looking directly at something.

Age related macular degeneration affects this central area.

You may notice:

• Blurred central vision

• Difficulty reading

• Straight lines appearing wavy or distorted

• Difficulty recognising faces

• A dark, grey or blurred area in the centre of your vision

• Reduced ability to see fine detail

Macular degeneration does not affect everybody in exactly the same way. Some changes develop slowly over many years, while others can affect vision much more quickly.

What is the difference between dry and wet macular degeneration?

This is one of the most important things to understand following an AMD diagnosis.

Dry AMD is the more common form and usually develops gradually. Changes occur within the macula over time and the condition can range from relatively early changes to more advanced loss of central vision.

Wet AMD develops when abnormal blood vessels grow underneath the retina. These blood vessels can leak fluid or blood, which can damage the macula and cause a more rapid change in central vision.

Someone with dry AMD can later develop wet AMD.

This does not happen to everyone, but it means that a sudden change in vision when you already have dry AMD should not be ignored.

What is the best treatment for wet macular degeneration?

For many people with active wet AMD, the main treatment is anti vascular endothelial growth factor injections (anti VEGF injections).

Vascular endothelial growth factor (VEGF) is a substance within the body that can encourage the development of new blood vessels.

In wet AMD, abnormal blood vessels can develop beneath the retina and leak fluid or blood.

Anti VEGF medicines are designed to block this process and reduce the activity of these abnormal blood vessels.

The aim is to control the disease and protect as much central vision as possible.

Some patients also experience an improvement in their vision following treatment, although this cannot be guaranteed.

The outcome depends on factors including how advanced the condition is, how much damage has already occurred and how the eye responds to treatment.

Will I need more than one eye injection?

Wet AMD usually requires ongoing monitoring and many patients require repeated injections.

Treatment is not necessarily the same for everyone.

Initially, injections may be given relatively regularly. Your treatment schedule can then be adjusted according to how your eye responds.

This is where retinal imaging becomes particularly important.

Optical Coherence Tomography (OCT) is a scan that produces detailed images of the retina and macula. It allows us to look for changes such as fluid within or beneath the retina and helps us assess how the condition is responding to treatment.

The decision about whether another injection is required can therefore be guided by both your vision and what we can see within the macula.

Can eye injections cure wet macular degeneration?

Anti VEGF injections can be very effective at controlling wet AMD, but they do not cure the underlying condition.

The aim of treatment is generally to stop or reduce the activity of the abnormal blood vessels and protect vision from further damage.

This is why continued monitoring is important even when your vision feels stable.

Treatment also cannot always reverse damage that has already occurred.

If the macula has developed significant permanent damage or scarring, some visual loss may remain even when the active wet AMD has been successfully controlled.

This is one reason why early assessment of new symptoms is so important.

What can be done for dry macular degeneration?

Dry AMD requires a different approach.

There is currently no routine treatment that can reverse the changes caused by dry AMD.

However, this does not mean that nothing can be done.

Management may involve:

• Monitoring changes in your vision

• Regular eye assessments where appropriate

• Addressing relevant lifestyle factors

• Discussing nutritional supplements when appropriate

• Supporting your remaining vision

• Recognising symptoms that may indicate progression

One particularly important part of managing dry AMD is knowing what changes should prompt further assessment.

If you have dry AMD and suddenly notice that straight lines look wavy, your central vision becomes significantly more blurred or a new dark or missing area appears, this should be assessed promptly.

These symptoms can sometimes indicate that wet AMD has developed.

Can vitamins help with macular degeneration?

This is a common question, particularly because there are many supplements marketed for eye health.

Certain combinations of vitamins and minerals may be recommended for some people with particular stages of AMD.

However, supplements are not a cure for macular degeneration, and they are not automatically appropriate for everybody with the condition.

The most suitable advice depends on the type and stage of AMD you have, alongside your wider health and individual circumstances.

It is therefore sensible to discuss supplements with an appropriate eye care professional rather than assuming that any general eye health vitamin will prevent AMD from progressing.

How do we decide which treatment is right for you?

The words “macular degeneration” alone are not enough to determine the best treatment.

We need to understand what is happening inside your individual eye.

A detailed assessment may consider:

• Whether you have dry or wet AMD

• How advanced the condition is

• Whether there is fluid or bleeding within the retina

• Whether your vision has recently changed

• Whether one or both eyes are affected

• Whether another eye condition is also contributing to your symptoms

Optical Coherence Tomography (OCT) can be particularly useful because it allows the layers of the retina and macula to be examined in detail.

Other conditions can also affect vision at the same time.

For example, a cataract causes clouding of the natural lens inside the eye, while AMD affects the retina at the back of the eye. Someone who has both conditions may therefore experience visual problems for more than one reason.

Similarly, people with diabetes can develop diabetic retinopathy, which occurs when diabetes damages the small blood vessels within the retina. Diabetes can also cause swelling within the macula.

A careful assessment helps distinguish between these conditions so that treatment is directed towards the actual cause of the visual problem.

How do I know if my macular degeneration is getting worse?

Changes to your central vision are particularly important.

You may notice:

• Straight lines beginning to look wavy

• Reading becoming noticeably more difficult

• Faces becoming harder to recognise

• A new blurred or dark area centrally

• Part of an object appearing missing

• A noticeable difference between your two eyes

If these symptoms are new or have developed suddenly, you should seek appropriate eye care advice.

Do not assume that a sudden deterioration is simply a normal part of having macular degeneration.

Can macular degeneration treatment save my vision?

The aim of treatment depends on the type and stage of AMD.

For wet AMD, treatment can often help control the disease and reduce the risk of further loss of central vision. Some patients may also experience improvement.

However, treatment cannot always restore vision that has already been permanently lost through damage to the macula.

With dry AMD, the focus is usually on monitoring progression, identifying significant changes and helping you make the best use of your remaining vision.

This is why realistic expectations are important.

The aim is not simply to offer a treatment. It is to understand what can realistically be achieved for your individual eyes.

Why specialist assessment matters

Macular degeneration can vary considerably from one person to another.

As a Consultant Ophthalmologist and Medical Retina Specialist, I assess and treat conditions affecting the retina and macula, including wet macular degeneration and diabetic eye disease, alongside cataract assessment and surgery.

For someone with AMD, specialist assessment can help establish whether the condition is dry or wet, whether treatment is required and how the health of the macula may affect your vision.

It also provides an opportunity to discuss your concerns in straightforward language and understand what you can realistically expect from treatment or monitoring.

The bottom line

There is no single best treatment for every person with macular degeneration.

The key points to remember are:

• Dry and wet AMD are managed differently

• Wet AMD is commonly treated with anti VEGF eye injections

• These injections aim to control the disease and protect central vision

• Repeat injections may be required

• Dry AMD is generally managed through monitoring and appropriate support

• New or sudden changes in central vision should be assessed promptly

• OCT scans can help diagnose and monitor changes within the macula

• Other conditions, including cataracts and diabetic eye disease, may also contribute to changes in vision

Ultimately, the most useful question may not simply be:

“What is the best treatment for macular degeneration?”

But:

“What type of macular degeneration do I have, and what treatment is most appropriate for my eyes?”
