15246 Macular Degeneration

Overview

Macular degeneration is an eye condition that affects the central part of your vision. It happens when the macula, the small central area of the retina that lets you see fine details, becomes damaged. This can make reading, driving, and recognizing faces harder, but it does not cause total blindness because your side vision usually remains.

Yes, it is one of the leading causes of vision loss in people over 50 in developed countries. Many people have early signs without noticing at first.

It mostly affects older adults, especially those over 60. It can also run in families. Smoking, high blood pressure, and being overweight increase the risk. It is very rare in children or young adults.

Symptoms

Common symptoms

• Blurred or distorted central vision, such as straight lines appearing wavy
• Difficulty reading or seeing faces clearly
• Dark or empty spots in the center of your vision
• Colors appearing less bright or vivid
• Needing brighter light for close-up tasks

Symptoms in children

• Macular degeneration is extremely rare in children. If a child has similar symptoms, it is usually due to another eye condition and needs a full eye exam.

Symptoms in older adults

• The first signs often include needing more light to read, trouble recognizing people's faces, or words looking distorted. Some people notice a small blind spot in the center of one eye.

Causes

Main causes

• Aging causes the macula to thin and break down over time.
• Tiny yellow deposits called drusen can build up under the retina.
• In the wet form, abnormal blood vessels grow under the retina and leak fluid or blood.

Risk factors

• Being over the age of 60
• Having a family history of macular degeneration
• Smoking (or being exposed to secondhand smoke)
• Having high blood pressure or high cholesterol
• Being obese or eating a diet high in saturated fats
• Having light-colored eyes and being exposed to bright sunlight without protection

When to see a doctor

See a doctor urgently if:

• Call your local emergency number if you have sudden loss of vision, severe distortion, or a dark curtain over your vision — these need immediate medical attention.
• If you have any sudden vision change, seek same-day care from an eye doctor or emergency department.

Book a routine appointment if:

• If you are over 50, have regular eye exams every 1–2 years.
• If you notice gradual blurring, difficulty reading, or changed color perception, book an eye test with your optometrist or GP.
• If you have risk factors like smoking or a family history, ask your doctor about more frequent checks.

Diagnosis

Macular degeneration is diagnosed by an eye care professional during a comprehensive eye exam. This usually involves simple painless tests to look at the back of your eye and the health of your retina.

Tests that may be done

• A visual acuity test using an eye chart
• A dilated eye exam, where eye drops make your pupils wider so the retina can be seen clearly
• An optical coherence tomography (OCT) scan, which takes detailed cross-section images of the retina
• A fluorescein angiography, where a dye is injected into a vein to see blood vessels in the retina (sometimes used if the wet form is suspected)

What to expect at your appointment

The exam is painless. The dilating drops may make your vision blurry and bright lights feel dazzling for a few hours, so it's a good idea to bring someone to drive you home.

Treatment

There is no cure for macular degeneration yet, but treatments can slow its progression and help you make the most of your remaining vision. The dry form is managed with lifestyle changes, support, and sometimes special vitamin and mineral supplements. The wet form may be treated with regular eye injections to reduce abnormal blood vessel growth and prevent further damage.

Self-care at home

• Eat a healthy diet rich in leafy green vegetables, fish, nuts, and fruit
• Stop smoking and avoid secondhand smoke
• Wear sunglasses that block UV light when outdoors
• Use an Amsler grid at home to check your vision regularly and report any changes
• Keep other health conditions like high blood pressure well controlled

Medical treatments

In general, treatments aim to stop the growth of abnormal blood vessels or reduce their leakage. This may involve regular injections into the eye (given by a specialist), or occasionally laser or other light-based therapies. For certain stages of the dry form, an eye specialist may recommend a specific combination of antioxidant vitamins and minerals based on your condition. Always discuss any treatment, including supplements, with your doctor or pharmacist — never take high-dose supplements without medical advice.

When is surgery considered?

Surgery is not a standard treatment for macular degeneration itself. However, cataract surgery may improve overall vision if you also have cataracts. Your eye specialist can tell you if surgery is an option for your situation.

Living with this condition

Living with central vision loss takes adaptation. Use bright, direct lighting for reading and hobbies. Try large-print books, magnifying lenses, e-readers with adjustable text, and talking devices. Arrange your home so items are easy to find and reduce fall risks like loose rugs.

Lifestyle tips

• Stay socially connected — tell friends and family how they can help you feel included
• Ask your eye clinic about low vision rehabilitation services
• Try smartphone apps that read text aloud or magnify objects
• Keep active with gentle exercise like walking or tai chi, if your doctor agrees
• Use contrast — for example, dark cutting boards on light counters — to make tasks easier

Diet and exercise

A Mediterranean-style diet with plenty of leafy greens, fish, whole grains, and nuts may support eye health. Regular exercise helps maintain a healthy weight, blood pressure, and cholesterol, which are all good for your eyes and overall health.

Mental health and emotional wellbeing

It is normal to feel anxious, frustrated, or sad when coping with vision changes. You are not alone. Talk to your doctor or a counselor about these feelings. If you ever feel overwhelmed or have thoughts of harming yourself, reach out to your local emergency services or a mental health crisis line right away — there is always help.

Prevention

You can't always prevent macular degeneration, but you can lower your risk. Don't smoke, eat a balanced diet, wear sunglasses outdoors, exercise regularly, and keep your blood pressure and cholesterol in check. Most importantly, have regular eye exams so any early signs are found as soon as possible.

Screening programmes

Routine eye exams are the main screening method. If you're over 50, have an eye check every 1–2 years. At home, an Amsler grid can help you notice changes in your central vision between appointments.

Complications

If left untreated

• Central vision can become severely impaired, making reading, driving, and recognizing faces very difficult
• Reduced vision raises the risk of falls and fractures
• It may lead to social isolation, anxiety, or depression

Long-term outlook

The outlook is more hopeful than many people expect. With early diagnosis, proper treatment, and good support, most people with macular degeneration continue to lead full and independent lives. The wet form can often be stabilized with treatment, and low vision services can help you adapt. Total blindness from macular degeneration is very rare because side vision is usually preserved.
