Age Related Macular Degeneration Amd

Overview

Age-related macular degeneration (AMD) is a common eye condition that affects the part of the eye responsible for sharp, central vision — the macula. It usually develops slowly as you get older and can make it harder to read, drive, or see faces clearly.

Yes. AMD is the most common cause of sight loss among adults aged 50 and older in the UK and many other countries.

It mainly affects older people, particularly those over 60. You are also more likely to develop it if you smoke, have a family history, or have high blood pressure.

Symptoms

Common symptoms

• Blurred or reduced central vision
• Difficulty reading or seeing fine details, even with glasses
• Straight lines appear wavy or bent
• Colours look dimmer or less vivid
• Difficulty recognising people's faces
• A dark or empty spot in the centre of your vision

Symptoms in children

• AMD is an age-related condition and almost never happens in children. If a child has similar symptoms, it is likely to be another eye problem and should be checked by a paediatric eye specialist.

Symptoms in older adults

• Early signs include needing brighter light for reading, finding it harder to adapt from bright to dim light, and noticing that words look smudged or shapes seem distorted.
• If you are older and notice any new or sudden changes in your vision, get it checked quickly.

Causes

Main causes

• In dry AMD, the macula slowly thins and small yellow deposits form underneath. The light-sensitive cells gradually stop working.
• In wet AMD, abnormal blood vessels grow under the retina and leak fluid or blood, causing damage and rapid symptoms.
• The exact cause is not known, but it involves a combination of ageing, genetics, and lifestyle factors.

Risk factors

• Getting older, especially being over 60
• Smoking, which greatly increases your risk
• Having a family history of AMD
• Having high blood pressure or cardiovascular disease
• Being overweight
• A diet low in fruits, vegetables, and omega-3 fatty acids

When to see a doctor

See a doctor urgently if:

• Seek urgent same-day advice from an eye clinic or your GP if you have a sudden change in your vision, such as blurred central vision, distortion, or a new dark patch.
• If you have sudden vision loss or other emergency symptoms, call your local emergency number immediately.

Book a routine appointment if:

• Make an appointment for an eye examination if you have persistent, gradual changes in your reading vision or difficulty seeing fine details.
• If you are over 60 and haven't had an eye test in the last year, book one as a routine check.

Diagnosis

AMD is diagnosed through a detailed eye examination by an optometrist (eye health professional) or an ophthalmologist (eye specialist). They will ask about your symptoms and medical history, then examine the back of your eyes.

Tests that may be done

• Visual acuity test: reading letters on an eye chart to check how sharp your central vision is.
• Amsler grid: looking at a small grid to check for wavy lines or missing areas.
• Examination of the retina after dilating (widening) your pupils with eye drops.
• Optical coherence tomography (OCT): a quick, painless scan that gives detailed images of the layers of the retina.
• Fluorescein angiography: a special camera takes pictures after a dye is injected into your arm, to check for abnormal blood vessels in wet AMD.

What to expect at your appointment

Most eye tests are painless and done while you are awake. The dilating drops may take up to half an hour to work and can cause light sensitivity and blurry vision for a few hours. You may need someone to drive you home. Your optometrist or specialist will explain the results and next steps clearly.

Treatment

There is no cure for AMD yet, but early treatment can slow it down and help protect your sight. The best option depends on the type and stage of your AMD. Your eye specialist will talk through the risks and benefits with you.

Self-care at home

• Stop smoking — this is one of the most effective ways to slow further damage.
• Wear sunglasses or a brimmed hat in bright sunlight.
• Use brighter lighting at home and while reading.
• Use magnifying glasses, large print books, or other low-vision aids.
• Keep a healthy weight and stay active.

Medical treatments

For wet AMD, the standard treatment is a course of injections into the eye. These medicines block the growth of the abnormal blood vessels that leak and damage the macula. The injections are given in the eye clinic and are usually repeated over time. For dry AMD, there is no specific medical treatment yet, but some vitamin and mineral supplements — if recommended by your eye specialist — may reduce the risk of progression in certain stages. Always discuss any treatments or supplements with a qualified healthcare professional.

When is surgery considered?

Surgery is rarely used for AMD. For a very small number of people with certain features of wet AMD, operations such as removing blood from the eye or moving the macula may be considered, but these are uncommon and only offered after careful discussion with a specialist.

Living with this condition

Living with AMD means learning to make the most of the sight you have. Try looking slightly to one side instead of straight ahead to use your clearer side vision. Use stronger lighting, magnifying lenses, and make your home easier to navigate. Many devices and apps can read text aloud. An occupational therapist or low-vision service can help you find practical solutions.

Lifestyle tips

• Stay connected with family and friends, even if you worry about your sight.
• Keep up with hobbies that don't need sharp central vision, like listening to music or podcasts.
• Join a support group for people with vision loss, in person or online.
• Keep all eye appointments and report any new symptoms quickly.

Diet and exercise

A Mediterranean-style diet rich in leafy green vegetables, fruits, nuts, fish, and healthy oils is good for eye and blood vessel health. Regular exercise helps control blood pressure and weight, which can also help protect your eyes. If you are thinking about supplements, ask your specialist whether they are suitable for you.

Mental health and emotional wellbeing

Vision loss can be frustrating and is linked to anxiety and depression. It's completely normal to feel upset or worried. Talk to your GP or eye clinic about how you feel — they can offer counselling or connect you with peer support. If you are feeling in crisis, reach out to your local mental health helpline or emergency services.

Prevention

You cannot always prevent AMD, especially because age and genetics play a role. But you can lower your risk by not smoking, protecting your eyes from sunlight, keeping your blood pressure and cholesterol in a healthy range, and eating a balanced diet.

Vaccines

There is no vaccine to prevent AMD.

Screening programmes

Regular eye tests are your best form of screening. They can spot early signs of AMD before you notice vision changes. Ask your optometrist about how often you should be tested, especially if you are over 60 or have a family history.

Complications

If left untreated

• Untreated wet AMD can lead to rapid and permanent loss of central vision.
• Scarring or bleeding in the macula may occur, making reading and facial recognition very difficult.
• Severe sight loss increases the risk of falls, social isolation, and difficulty managing daily routines.

Long-term outlook

The outlook for AMD is better than many people think. Dry AMD usually progresses slowly, and many people keep good vision for many years. Wet AMD can often be stabilised with prompt treatment. And even if central vision is lost, your side vision remains, which can help you continue doing many daily tasks with the right support. Scientists are constantly researching new treatments, so there is reason for hope.
