Age-related Macular Degeneration (AMD)

Introduction

Age-related macular degeneration, usually shortened to AMD, is a long-term eye condition that affects the central part of your vision. If you or a family member has been diagnosed with AMD, you are likely thinking about what comes next — what treatment looks like, how the condition may change over time, and how to protect the vision you have.

AMD is one of the leading causes of vision loss in people over the age of 50 worldwide. It does not cause complete blindness in most people. Side vision, also called peripheral vision, is usually preserved. But the central vision — the part you use for reading, recognising faces, driving, and seeing fine detail — can become blurred, distorted, or develop a blank patch over time.

The good news is that AMD is much more treatable today than it was twenty years ago, especially the wet form. Regular monitoring, lifestyle measures, and timely treatment can slow progression for many people and preserve useful vision for years. This article walks through what AMD is, the two main types, how it is diagnosed and treated, and what daily life with the condition can look like.

What Is AMD?

To understand AMD, it helps to know a little about the back of the eye. Light entering your eye is focused onto the retina, a thin layer of light-sensing tissue lining the inside of the eyeball. In the centre of the retina is a small but very important area called the macula. The macula is responsible for sharp, detailed central vision — the kind you use for reading, threading a needle, or seeing someone’s expression clearly.

In AMD, the macula gradually becomes damaged. The cells that detect light start to break down, and in some forms of the disease, abnormal blood vessels grow beneath the retina and leak fluid or blood. The result is loss of central vision. The rest of the retina — and therefore most of your side vision — usually keeps working.

AMD is called “age-related” because it is strongly linked to ageing. It typically develops after age 50 and becomes more common with each passing decade. There are other macular conditions that affect younger people (such as Stargardt disease or juvenile macular dystrophies), but these are different diseases and are not part of AMD.

Types of AMD

Dry AMD (Non-neovascular AMD)

Dry AMD is the more common form, accounting for around 85 to 90 percent of cases. It develops slowly, often over many years. The earliest sign that an eye doctor sees during an examination is the build-up of small yellow deposits under the retina called drusen. Drusen are made of fats and proteins, and small amounts are a normal part of ageing. Larger and more numerous drusen are a sign of AMD.

• Early AMD — small or medium-sized drusen are present, but vision is typically not affected and the person may not notice any change.
• Intermediate AMD — larger drusen and pigment changes are visible in the retina. Some people start to notice mild blurring, difficulty reading in low light, or needing more light for close work.
• Late (advanced) dry AMD — areas of the macula lose their light-sensing cells. This is called geographic atrophy. Central vision loss in this stage is more noticeable and can interfere with daily activities.

Dry AMD can remain stable for a long time, progress slowly, or in some people advance to the wet form.

Wet AMD (Neovascular AMD)

Wet AMD is less common but tends to cause faster and more severe vision loss if not treated. In wet AMD, abnormal new blood vessels grow under the retina from the layer beneath, called the choroid. These vessels are fragile and leak fluid or blood into and under the macula. The leakage damages retinal cells and distorts vision.

Wet AMD can develop in someone who previously had dry AMD, or it can appear without much warning. Symptoms include sudden blurring, a dark or empty patch in the centre of vision, or straight lines (like door frames or grid patterns) that appear wavy or bent. Wet AMD is considered an urgent condition because treatment works best when started early.

Causes and Risk Factors

The exact cause of AMD is not fully understood. It is thought to result from a combination of ageing, genetics, and environmental factors that together damage the cells of the macula over time.

The main risk factors include:

• Age — the strongest risk factor. Risk rises sharply after age 60.
• Family history — having a parent or sibling with AMD increases your risk. Several genes have been linked to the condition.
• Smoking — smokers are at significantly higher risk of developing AMD and of progressing to the advanced stages. This is one of the most important modifiable risk factors.
• High blood pressure and cardiovascular disease — conditions that affect blood vessels also appear to affect the small vessels supplying the retina.
• Diet low in green leafy vegetables, fish, and antioxidants — nutrition plays a role, particularly in dry AMD.
• Obesity — linked to higher progression risk.
• Light skin and light eye colour — people of European ancestry have higher rates of AMD, though the condition occurs in all populations.
• Long-term, intense sunlight exposure — some studies suggest a small role, though the evidence is mixed.
• Female sex — women have slightly higher rates, partly because they live longer on average.

If you have already been diagnosed with AMD, you are likely familiar with some of the early symptoms. This section focuses on the changes that may signal progression or a switch from dry to wet AMD — the changes that should prompt you to contact your eye doctor without delay.

Symptoms of AMD progression include:

• Blurred or hazy central vision, especially when reading or recognising faces
• A dark, blank, or empty spot in the centre of your vision
• Straight lines appearing wavy, bent, or distorted — for example, door frames, window edges, or the lines on a grid
• Colours appearing less bright or less distinct
• Increased difficulty adapting to low light or moving from a bright to a dim environment
• Needing brighter light to read or do close work
• Words or letters that look broken, missing, or jumbled when reading

A sudden change in any of these symptoms — particularly new distortion, a new dark spot, or rapid blurring — should be treated as urgent. It may indicate the development of wet AMD, where prompt treatment makes a real difference to the outcome.

Many eye specialists give patients a small printed Amsler grid, a square of straight lines with a dot in the centre, to check their vision at home. Looking at the grid with one eye at a time can help you notice early changes between appointments.

Diagnosis

AMD is diagnosed through a detailed eye examination by an ophthalmologist (eye doctor) or retinal specialist. Several tests are used together to confirm the type of AMD and assess its severity.

Visual Acuity Test

This is the familiar letter chart used to measure how clearly you can see at distance and at near. It gives a baseline measurement of your central vision.

Dilated Eye Examination

Eye drops are used to widen your pupils so the doctor can examine the back of the eye in detail. Drusen, pigment changes, areas of atrophy, and abnormal blood vessels can be seen this way. Your vision will be blurry and light-sensitive for a few hours after dilation.

Optical Coherence Tomography (OCT)

OCT is the most important imaging test in AMD. It uses light waves to take very detailed cross-section pictures of the retina, layer by layer. OCT can show small amounts of fluid, swelling, drusen, and thinning of the retinal layers. It is painless and quick, and it is used both for diagnosis and to monitor treatment response over time.

OCT Angiography (OCT-A)

A newer form of OCT that shows the blood vessels in and beneath the retina without injecting any dye. It is useful for detecting the abnormal vessels of wet AMD.

Fluorescein Angiography

A dye is injected into a vein in your arm and photographs of the retina are taken as the dye travels through the blood vessels of the eye. Leaking abnormal vessels show up clearly. This test is used less often now that OCT-A is widely available, but it is still useful in some cases.

Amsler Grid

As mentioned earlier, this simple grid is used both in the clinic and at home to detect distortion or blank patches in central vision.

The combination of these tests allows the doctor to determine whether you have dry or wet AMD, how advanced it is, and which eye is more affected. AMD often affects both eyes, but not always at the same rate.

Treatment and Management

Treatment for AMD depends on the type and stage. Dry AMD does not yet have a cure, but progression can sometimes be slowed. Wet AMD has effective treatments that can preserve and sometimes improve vision when started early.

Treatment for Dry AMD

AREDS2 supplements. The Age-Related Eye Disease Study (AREDS) and its follow-up AREDS2, conducted by the United States National Eye Institute, showed that a specific combination of vitamins and minerals can reduce the risk of intermediate dry AMD progressing to advanced AMD. The AREDS2 formulation contains vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin. These supplements are not a cure and do not reverse damage that has already occurred, but they are commonly recommended by ophthalmologists for patients with intermediate or advanced AMD in at least one eye. They are generally not advised for people with early AMD or no AMD, because the benefit has not been shown for those groups. Whether AREDS2 supplements are right for you is a clinical decision based on the stage of your AMD.

Newer treatments for geographic atrophy. Until recently, there were no specific treatments for late-stage dry AMD (geographic atrophy). In some countries, injectable medications have been approved that slow the rate at which the atrophic areas expand. Availability varies by region, and these treatments are still relatively new. Your retinal specialist can tell you what is available and whether it is appropriate in your situation.

Lifestyle and risk-factor management. For dry AMD at all stages, controlling modifiable risk factors is an important part of care. This is discussed in more detail below.

Treatment for Wet AMD

Anti-VEGF injections. The mainstay of treatment for wet AMD is a class of medications called anti-VEGF drugs. VEGF stands for vascular endothelial growth factor, the signal that drives the growth of the abnormal blood vessels in wet AMD. Anti-VEGF medications block this signal, causing the vessels to shrink and stop leaking. The medication is delivered as an injection directly into the eye (intravitreal injection).

The injection sounds frightening but is well tolerated by most patients. The eye is numbed with anaesthetic drops and cleaned with antiseptic. A very fine needle is used, and the injection itself takes only a few seconds. Most people describe a brief pressure or stinging sensation rather than pain. You may have some redness, mild discomfort, or floaters for a day or two afterwards.

Several anti-VEGF medications are in clinical use, including ranibizumab, aflibercept, brolucizumab, faricimab, and bevacizumab (used off-label for the eye in many countries). Your retinal specialist will choose the medication based on your specific case, the response of the eye, and what is available.

Anti-VEGF treatment is not a one-time event. Injections are typically given monthly at first, then less often as the eye responds, following one of several established schedules. Major societies including the American Academy of Ophthalmology describe early and consistent treatment as central to good outcomes in wet AMD. Treatment may continue for years.

Photodynamic therapy (PDT). An older treatment in which a light-sensitive drug is injected into the bloodstream and then activated by a laser shone into the eye. PDT is used much less often now that anti-VEGF treatment is available, but it still has a role in certain types of wet AMD, sometimes in combination with anti-VEGF injections.

Laser photocoagulation. A focused laser that seals leaking blood vessels. This was once the main treatment for wet AMD but is rarely used today because it can damage the surrounding healthy retina. It may still be considered in specific situations where the abnormal vessels are away from the centre of the macula.

Low-Vision Rehabilitation

For people whose central vision has already been affected, low-vision rehabilitation can make a meaningful difference to daily life. This is not a treatment for AMD itself but a set of services that help you make the most of remaining vision. Low-vision rehabilitation may include:

• Magnifying devices for reading — handheld, stand-mounted, or electronic
• Specialised lighting recommendations for reading and close work
• Software that enlarges text or reads it aloud on phones, tablets, and computers
• Training in eccentric viewing — using the side parts of the retina more effectively when central vision is reduced
• Home modifications for safety and ease of moving around
• Support and counselling for the emotional adjustment to vision loss

Several lifestyle measures can help slow progression of AMD and protect your remaining vision. These are not optional add-ons — they are part of the standard management plan that ophthalmologists discuss with every patient.

Stop Smoking

Smoking is the single most important modifiable risk factor for AMD. People who smoke develop AMD earlier, progress faster, and respond less well to treatment. Stopping smoking at any stage of the disease is beneficial. Support services, nicotine replacement, and medications can help.

Eat a Diet Rich in Leafy Greens, Fish, and Colourful Vegetables

A diet pattern often described as “Mediterranean style” — high in green leafy vegetables, fruits, whole grains, fish, nuts, and olive oil, and low in processed foods and red meat — has been linked to slower AMD progression in several studies. Specific foods that contain the same nutrients found in AREDS2 supplements (lutein, zeaxanthin, omega-3 fatty acids, vitamin C, vitamin E, zinc) include spinach, kale, broccoli, eggs, oily fish such as salmon and sardines, citrus fruits, and nuts.

Manage Blood Pressure, Cholesterol, and Blood Sugar

These cardiovascular risk factors also affect the small blood vessels in the eye. Working with your physician to keep them well controlled supports both general and eye health.

Maintain a Healthy Weight and Be Active

Regular physical activity and a healthy weight are associated with lower risk of AMD progression.

Protect Your Eyes from Bright Sunlight

Wearing sunglasses that block ultraviolet (UV) light, along with a wide-brimmed hat outdoors, is a reasonable precaution. The evidence on UV light and AMD is not as strong as for smoking or diet, but eye protection is harmless and protects against other eye conditions as well.

Use Your Amsler Grid Regularly

Checking each eye separately with an Amsler grid — many people do this once a day or several times a week — can help you detect distortion or blank spots early. Place the grid on a wall or the refrigerator at a comfortable reading distance, cover one eye, and look at the central dot. Any new wavy lines, missing areas, or distortion should be reported promptly.

Monitoring and Follow-up

AMD is a long-term condition and follow-up is part of life with the diagnosis. The schedule depends on the type and stage.

• Early dry AMD — eye examinations are usually arranged every six to twelve months. Home Amsler grid monitoring is encouraged.
• Intermediate dry AMD — closer monitoring, often every six months, because the risk of progression to wet AMD is higher.
• Wet AMD on anti-VEGF treatment — frequent visits, usually every four to twelve weeks, with OCT scans to assess response and decide on the next injection.
• Stable AMD after a period of treatment — visit intervals may be lengthened, but routine review continues indefinitely.

At each visit, your doctor will check your vision, examine the retina, and usually perform an OCT scan. Bring a list of changes you have noticed and any Amsler grid findings to each appointment.

Complications and Progression

The most important complications of AMD are related to vision loss itself and its consequences.

Progression from dry to wet AMD. About 10 to 15 percent of people with dry AMD develop wet AMD in one or both eyes over time. This is why regular monitoring and home Amsler grid checks matter.

Geographic atrophy. In late dry AMD, areas of the macula lose their light-sensing cells permanently. This causes blank patches in central vision.

Scarring of the macula. In wet AMD, untreated or long-standing leakage can lead to scar tissue, which causes permanent central vision loss.

Falls and injuries. Reduced central vision, especially in low light, increases the risk of falls and accidents. Home modifications, good lighting, and removing trip hazards become important.

Difficulty driving. Many people with moderate or advanced AMD eventually find that driving is no longer safe, particularly at night. This is a difficult adjustment for many patients.

Depression and isolation. Losing the ability to read, recognise faces, or pursue hobbies can have a serious emotional impact. Depression is more common in people with significant vision loss and is treatable. Talking to your doctor about mood changes is important.

Charles Bonnet syndrome. Some people with significant vision loss experience visual hallucinations — seeing patterns, shapes, faces, or scenes that are not there. This is not a mental illness; it is the brain’s response to reduced visual input. It can be unsettling but is harmless. Knowing it exists often makes it easier to live with.

Living with AMD

A diagnosis of AMD changes daily life in ways that vary with the stage of the condition. Many people in the early stages have little or no functional change for years. Others adapt over time as central vision decreases. The following considerations help with everyday living.

Reading and Close Work

Bright, even, glare-free lighting makes a substantial difference. Task lamps placed beside or behind your shoulder, magnifiers (handheld, stand, or electronic), large-print books, and audiobooks are all useful options. Tablets and e-readers allow you to increase font size and adjust contrast.

Using Phones and Computers

Modern smartphones and computers have built-in accessibility features — text magnification, screen readers, high-contrast modes, and voice control. Spending an hour learning these settings can transform daily use of devices.

Driving

The decision to continue driving with AMD depends on your level of vision, lighting conditions, and local rules. Your ophthalmologist can advise on whether your vision meets the legal standard. Many people with AMD switch to driving only in familiar areas, only during daylight, and only on quiet roads before stopping altogether. Public transport, family support, and ride services can help maintain independence.

Home Safety

Good lighting throughout the home, contrasting colours on stair edges, removal of loose rugs, and grab rails in bathrooms reduce the risk of falls. An occupational therapist with low-vision experience can do a home assessment.

Recognising Faces and Social Life

Difficulty recognising faces can be socially uncomfortable. Letting friends and family know you may not recognise them until they speak — and asking them to introduce themselves — reduces awkward moments. Social isolation is a real risk and worth guarding against.

Emotional Adjustment

Grief, frustration, and fear are common reactions to a diagnosis that affects vision. Support groups (in person or online), counselling, and connection with others living with AMD can help. If low mood persists or interferes with daily life, speaking to your doctor about it is important. Depression is treatable.

Preventing Progression and Protecting the Other Eye

Once one eye has been affected by AMD — especially wet AMD — the other eye is at higher risk. Several steps help reduce that risk:

• Stop smoking if you have not already
• Take AREDS2 supplements if your ophthalmologist has recommended them
• Eat a diet rich in leafy greens, fish, and colourful vegetables
• Keep blood pressure, cholesterol, and blood sugar in their target ranges
• Check each eye separately with the Amsler grid regularly, since one eye can compensate for the other and mask early changes
• Attend all scheduled follow-up visits, even when vision feels stable
• Report any new distortion, blurring, or blank spots without delay

If wet AMD develops in the second eye, prompt treatment with anti-VEGF injections gives the best chance of preserving useful vision.

A Note on AMD and Children

AMD is, by definition, a condition of older adults. It does not occur in children. Some children and young adults develop other macular conditions — such as Stargardt disease, Best disease, or juvenile macular dystrophies — that affect the same part of the retina but have different causes and treatments. These are not forms of AMD and are managed differently. If you are looking for information about a macular condition in a child, you will need information specific to that diagnosis rather than AMD.

When to Seek Urgent Care

Most AMD changes happen slowly. But certain changes need prompt attention because they may indicate new wet AMD or another retinal problem where time matters. Contact your eye doctor without delay if you notice:

• A sudden new dark or blank spot in your central vision
• Sudden or rapidly worsening blurring of central vision
• New distortion of straight lines (door frames, edges of objects, grid patterns)
• A sudden shower of new floaters, flashes of light, or a curtain or shadow across part of your vision — these may suggest a different urgent retinal problem such as a retinal detachment
• Sudden eye pain, redness, or marked light sensitivity after a recent intravitreal injection

Wet AMD treated within days to a few weeks of onset usually has a much better outcome than wet AMD treated later. It is always better to be checked and reassured than to delay.

Frequently Asked Questions

Will I go completely blind from AMD?

For the great majority of people, no. AMD damages central vision but spares peripheral vision. Even in advanced cases, side vision is usually preserved well enough to allow people to move around their environment and remain independent with appropriate support. Complete blindness is very rare from AMD alone.

Is AMD inherited? Should my children be screened?

Family history is a known risk factor, and several genes have been linked to AMD. Having a parent or sibling with AMD increases your own risk but does not make the condition certain. Children of people with AMD do not usually need formal genetic testing, but they benefit from knowing the family history, avoiding smoking, eating well, and having regular eye examinations after age 50 (or earlier if symptoms appear).

Are the eye injections painful?

Most people describe the injection as uncomfortable rather than painful. The eye is numbed with anaesthetic drops before the procedure, and the needle is very fine. You may feel pressure or stinging for a moment. Mild redness, irritation, or floaters for a day or two afterwards are common. Serious complications from intravitreal injections are uncommon when performed by experienced specialists.

How long will I need to keep getting injections?

Anti-VEGF treatment for wet AMD is typically long-term. Some people need injections monthly at first, then less often as the eye stabilises. Others need frequent injections for many years. The schedule is adjusted based on how the eye responds, which your specialist will follow using OCT scans. Stopping treatment too early often allows the abnormal vessels to leak again.

Can AMD be cured?

There is no cure for AMD at present. Treatments slow or stop progression and, in wet AMD, can sometimes improve vision — but the underlying condition remains. Research into gene therapy, stem cell treatment, and new drug classes is active, and the treatment landscape has changed considerably over the past two decades.

Should I take AREDS2 supplements?

AREDS2 supplements have been shown to reduce the risk of progression in people with intermediate or advanced AMD in at least one eye. They are not recommended for people without AMD or with only early AMD, because the benefit has not been shown for those groups. Whether they are right for you is a decision to discuss with your ophthalmologist, who knows the stage of your AMD and your overall health. Smokers and former smokers need a specific formulation that does not contain beta-carotene.

Can I still read, watch television, or use my phone?

Yes, in most cases, with adaptations. Good lighting, larger text, magnifiers, audiobooks, and accessibility features on devices all help. A low-vision assessment can identify tools tailored to your level of vision.

Is there anything I can do to reverse the damage already done?

Damage to the macula from AMD is generally not reversible. Treatments aim to preserve the vision that remains and slow further loss. Low-vision rehabilitation helps you make the most of remaining vision.

Does using my eyes a lot make AMD worse?

No. Reading, using a computer, or doing close work does not worsen AMD. Using your eyes does not wear them out. Continue with the activities you enjoy, adapting them as needed.

Are there any new treatments on the horizon?

Active areas of research include longer-acting anti-VEGF drugs (so that injections are needed less often), implants that release medication slowly inside the eye, gene therapies, complement system inhibitors for geographic atrophy, and stem cell therapies. Your retinal specialist can tell you what is currently available and what trials may be relevant.

Conclusion

Age-related macular degeneration is a long-term condition that changes the way you see the centre of your visual world. It does not usually take away the ability to navigate your surroundings, and for many people it does not cause severe vision loss for years. The treatment landscape has improved markedly — anti-VEGF injections for wet AMD have changed outcomes in a way that was not possible two decades ago, and new treatments continue to emerge.

The most important steps with AMD are steady ones: attending follow-up visits, monitoring your vision at home, reporting changes promptly, managing modifiable risk factors (especially smoking), and adapting daily life with tools and support to make the most of the vision you have. Vision loss is also an emotional experience, and seeking support — from family, support groups, or mental health professionals — is part of caring for yourself.

Living well with AMD is possible, and a strong working relationship with an ophthalmologist or retinal specialist who knows your eyes is at the centre of that care.
