Age-related macular degeneration (AMD): Symptoms, treatment

If you’ve ever stretched your arm to read a menu, congratulated yourself on your
“long arms,” and then realized the words are still blurry, welcome to the club of
getting older. Now imagine that blur sitting right in the center of your vision,
not at arm’s length. That’s closer to what age-related macular degeneration (AMD)
can feel like a slow, sneaky thief of sharp central vision.

The good news? We know a lot about AMD: who is at risk, what the early symptoms
look like, and which treatments and lifestyle changes can help protect your sight.
This guide walks you through AMD symptoms, causes, treatment options, and real-life
experiences so you can move from “Wait, what is that?” to “Okay, I have a plan.”

What is age-related macular degeneration?

Age-related macular degeneration is a chronic eye disease that affects the
macula, the small but mighty central part of the retina at the back
of your eye. The macula is responsible for sharp, straight-ahead vision the kind
you use to read, recognize faces, drive, and scroll through your phone for longer
than you meant to.

In AMD, the macula gradually becomes damaged. Your peripheral (side) vision usually
stays intact, but your central vision can become blurry, distorted, or develop
dark spots. AMD is a leading cause of vision loss in older adults, especially
those over age 60.

Types and stages of AMD

AMD isn’t just one thing. It comes in different types and stages, which helps eye
doctors figure out the best treatment and monitoring plan.

Dry (atrophic) AMD

Dry AMD is the most common type, accounting for about 80–90% of cases. In dry AMD:

• Small yellow deposits called drusen form under the retina.
• Over time, the light-sensitive cells in the macula slowly break down.
• Vision changes tend to be gradual think months to years, not overnight.

Dry AMD usually progresses through three stages:

• Early AMD: Drusen are present, but you may have no symptoms.
  This is where regular eye exams can catch trouble before you notice anything.
• Intermediate AMD: Drusen are larger and more numerous. You
  might start to notice mild blurring or need brighter light for reading.
• Late AMD (geographic atrophy): Areas of the macula waste away,
  causing blind spots in the center of your vision.

Wet (neovascular or exudative) AMD

Wet AMD is less common but more serious. It occurs when abnormal, fragile blood
vessels grow under the macula and leak blood or fluid. That leakage lifts and
distorts the retina, leading to:

• Sudden or rapid worsening of central vision
• Dark or empty spots in the center of your sight
• Wavy or distorted straight lines (that classic “bent doorframe” look)

Wet AMD can develop from dry AMD at any time, which is why anyone with AMD needs
consistent monitoring, even when things seem stable.

Common symptoms of AMD

In the early stages, AMD is sneaky. You can have significant changes in your eyes
before you notice changes in your vision. As the disease progresses, you may
experience:

• Blurry or fuzzy central vision: Faces, words on a page, or
  details on a screen look hazy, even with your glasses on.
• Difficulty reading or seeing fine details: You might find
  yourself increasing font sizes, boosting brightness, or using stronger light.
• Straight lines look wavy or distorted: Door frames, floor tiles,
  or the lines in a notebook look bent or warped.
• Dark or empty area in the center of your vision: It may feel
  like someone placed a smudge or spot right in the middle of what you want to see.
• Colors look less vivid: Over time, colors may not “pop” the way
  they used to.

Because AMD typically affects both eyes (although not always at the same rate), one
eye can quietly compensate for the other. That’s why checking each eye separately
by covering one eye at a time can be surprisingly revealing.

Who is at risk? Causes and risk factors

We don’t have a single, simple cause of AMD. Instead, it’s a mix of age, genetics,
and lifestyle. Some factors you can’t control; others you absolutely can.

• Age: The biggest risk factor. AMD is most common in people
  over 60, but changes can start earlier.
• Family history and genetics: If a parent or sibling has AMD,
  your risk is higher. Certain genetic variations are strongly linked to the
  disease.
• Smoking: Smoking is one of the strongest modifiable risk
  factors. It damages blood vessels and increases inflammation in the retina.
• Cardiovascular health: High blood pressure, high cholesterol,
  obesity, and inactivity are all tied to increased AMD risk.
• Race and ethnicity: AMD is more commonly diagnosed in White
  adults, although it can affect people of all backgrounds.
• Diet and lifestyle: Diets low in fruits, vegetables, and
  omega-3 fats and high in processed foods may increase risk. A Mediterranean-style
  eating pattern appears protective.

You can’t go back in time and pick different parents. But you can stop
smoking, move more, eat better, and get regular eye exams and those choices
matter.

How AMD is diagnosed

AMD is usually picked up during a comprehensive, dilated eye exam.
Your eye care professional (optometrist or ophthalmologist) may use:

• Dilated fundus exam: Eye drops widen your pupils so the doctor
  can examine your retina and macula for drusen, pigment changes, or bleeding.
• Visual acuity test: The classic eye chart, but with a focus on
  central sharpness.
• Amsler grid: A square grid of straight lines you look at to
  check for wavy or missing areas in your central vision. Many people with AMD use
  an Amsler grid at home between visits.
• Optical coherence tomography (OCT): A painless imaging test
  that takes cross-sectional pictures of the retina, revealing swelling, fluid,
  or thinning.
• Fluorescein or indocyanine green angiography: A dye is injected
  into your arm and travels to the blood vessels in your eye, allowing the doctor
  to see abnormal blood vessels associated with wet AMD.

Early detection is huge. AMD treatments work best before severe damage occurs, and
lifestyle changes are most effective before vision is significantly impaired.

Treatment options for AMD

There’s no magic “reset” button for AMD yet, but there are effective ways to slow
progression, preserve vision, and maintain independence. Treatment depends on the
type and stage of AMD.

Treatment for dry AMD

For early dry AMD, the focus is usually on monitoring and
lifestyle changes. Your doctor may recommend:

• Regular eye exams and home monitoring with an Amsler grid to catch changes early.
• Quitting smoking if you smoke (yes, again it matters that much).
• Eating a diet rich in leafy greens, colorful fruits and vegetables, whole grains,
  fish, nuts, and healthy fats like olive oil.
• Managing blood pressure, cholesterol, and blood sugar with your primary care
  team.

For people with intermediate or advanced dry AMD in at least one
eye, eye doctors often recommend a specific high-dose vitamin and mineral blend
based on the AREDS2 (Age-Related Eye Disease Study 2) formula. These supplements
typically include:

• Vitamin C
• Vitamin E
• Zinc and copper
• Lutein and zeaxanthin (carotenoids that concentrate in the macula)

These supplements are not a cure, and they don’t help everyone. They’re meant for
specific stages of AMD and should be taken under the guidance of an eye care
professional, especially if you have other medical conditions or take medications.

Research is ongoing into new treatments for late-stage dry AMD (geographic
atrophy), including injectable drugs that may slow the rate of cell loss and
future options like gene or cell-based therapies.

Treatment for wet AMD

Wet AMD gets more aggressive treatment because vision can deteriorate quickly.
Treatment aims to stop or slow the leakage from abnormal blood vessels and, in
some cases, even improve vision.

Anti-VEGF injections

The mainstay of wet AMD treatment is anti-VEGF therapy.
VEGF (vascular endothelial growth factor) is a protein that encourages new blood
vessel growth. In wet AMD, VEGF goes into overdrive, causing those abnormal,
leaky vessels.

Anti-VEGF medications are injected directly into the eye (yes, that sounds
terrifying, but the eye is numbed, and most patients say it’s more weird than
painful). These drugs:

• Reduce leakage and swelling in the macula
• Can stabilize or improve vision in many patients
• Are often given every 4–12 weeks, depending on the drug and your response

Your retina specialist will decide which medication and schedule make most sense
for you, and they may adjust over time based on how your retina looks on OCT
imaging.

Laser and photodynamic therapy

In some cases, especially when abnormal blood vessels are in specific locations,
laser therapy or photodynamic therapy (PDT) may
be an option. These treatments use focused light, sometimes combined with a light-
sensitizing drug, to seal or destroy abnormal vessels and reduce leakage. They’re
used less commonly than anti-VEGF injections but can be helpful for selected
patients.

Emerging and advanced options

Researchers are actively working on longer-lasting drugs, implants that slowly
release medication, and even retinal implants or prosthetic devices for advanced
AMD. While these therapies are still evolving, they offer real hope that future
AMD treatment will be more durable, less burdensome, and more effective.

Low-vision rehabilitation and tools

Regardless of type, if AMD has already affected your vision, you’re not out of
options. Low-vision specialists can help you adapt and maintain independence using:

• Magnifying glasses or electronic magnifiers
• High-contrast reading materials and labels
• Large-print books and devices
• Screen readers and built-in accessibility features on phones and computers
• Training in lighting, contrast, and home modifications to improve safety

Vision rehabilitation doesn’t “fix” the retina, but it can dramatically improve
quality of life. Think of it as physical therapy for your eyes and your daily
routines.

Can AMD be prevented?

There’s no guaranteed way to prevent AMD, but you can stack the odds in your
favor. Eye health and overall health are deeply connected. Helpful steps include:

• Don’t smoke. If you smoke, quitting is one of the best things
  you can do for your eyes (and pretty much every organ).
• Follow an eye-friendly diet. Think Mediterranean style:
  leafy greens, colorful vegetables, berries, whole grains, fish, nuts, seeds,
  and olive oil.
• Move your body. Regular physical activity supports healthy
  blood vessels and blood pressure.
• Manage chronic conditions. Work with your healthcare providers
  to control blood pressure, cholesterol, and blood sugar.
• Wear sunglasses and a hat. Protect your eyes from strong UV
  light when outdoors.
• Get regular dilated eye exams. Especially after age 50 or if
  you have a family history of AMD.

These steps aren’t just “good for the eyes”; they’re good for your heart, brain,
and overall longevity. Your macula appreciates it and so does the rest of you.

Real-life experiences: Living with AMD day to day

Knowing the science of age-related macular degeneration is one thing. Living with
it or caring for someone who does is another story. Here are some common
experiences that many people with AMD describe, woven into a composite of real-
world challenges and solutions.

“I thought I just needed stronger glasses”

For many people, the first hint of AMD is subtle: words on a page that seem a
little fuzzy, needing brighter light than usual, or feeling like your glasses
suddenly became weaker overnight. It’s easy to blame aging or poor lighting and
delay making an eye appointment.

One common story goes like this: someone notices that the lines on their
crossword puzzle look slightly wavy. They ignore it for a while, hoping it will
go away. During a routine eye exam, the doctor spots drusen and early AMD. The
person walks out thinking, “I came in for new glasses and left with a new
diagnosis.”

The emotional reaction can range from mild anxiety to full-on panic. It’s normal
to worry about losing independence, driving, or reading. A big part of early AMD
care is simply education understanding that early detection gives you more tools
and time to protect your vision.

Getting used to injections

If you’re diagnosed with wet AMD, you might be told you’ll need injections directly
into your eye. That sentence alone can cause a spike in blood pressure. But many
patients say that, after the initial fear, the process becomes surprisingly routine.

Before the injection, numbing drops are used, and sometimes a small anesthetic
injection is given near the eye. The actual anti-VEGF injection takes seconds.
People often describe feeling pressure rather than pain. Afterward, they may feel
scratchiness or mild irritation for a day or two, but most are back to normal
activities quickly.

The bigger adjustment is the schedule. Monthly or every-other-month visits can
feel like a part-time job. Some people organize their lives around “shot day,”
arranging transportation, taking the rest of the day off, and rewarding themselves
with a favorite meal afterward. Over time, they often notice that the injections
stabilize their vision and that payoff helps with motivation.

Small changes that make a big difference

Living with AMD often means tweaking your environment rather than giving up your
favorite activities. People describe:

• Placing brighter lamps near reading chairs or favorite spots at the table.
• Using bold, felt-tip pens instead of ballpoint pens so writing is easier to see.
• Switching to high-contrast cutting boards in the kitchen (for example, dark
  board for light foods and light board for dark foods).
• Increasing text size on phones, tablets, and computers sometimes dramatically.
• Using voice assistants to read texts, reminders, or recipes aloud.

These “little” adjustments can preserve independence in big ways. A low-vision
specialist or occupational therapist can walk through your home and help you
design a space that works with your vision, not against it.

Impact on emotions and relationships

AMD doesn’t just affect eyes; it affects feelings, routines, and relationships.
Some people worry about being a burden or feel embarrassed when they can’t
recognize faces across the room. Others get frustrated when they can’t read
quickly or need help in unfamiliar environments.

Caregivers experience their own set of emotions concern about safety, uncertainty
about how much to help, and sometimes exhaustion from juggling appointments and
daily tasks. Honest conversations help. So does involving family members in eye
appointments so they can hear treatment plans and ask questions.

Support groups, whether in-person or online, can be extremely helpful. Hearing
“me too” from someone who understands the fear of losing vision and hearing how
they’ve adapted can be more powerful than any handout.

Finding a new normal

Over time, many individuals with AMD describe moving from panic to problem-solving.
The first phase is often fear: “Will I go blind?” Later comes a more practical
phase: “Okay, how do I keep doing the things I love, maybe in a different way?”

That might mean listening to audiobooks instead of reading print, using a magnifier
to continue a favorite craft, relying more on public transportation or rides from
friends, or choosing seating in restaurants with better lighting. None of these
changes are easy, but with the right support and tools, people with AMD often
continue to live active, meaningful lives.

Most importantly, AMD does not define who you are. It’s one part of your health
story, not the whole book.

When to see an eye doctor (and what to ask)

You should schedule an eye exam if you:

• Notice blurry or distorted central vision
• See dark or empty spots in the center of your sight
• Have a family history of AMD and are over 50
• Haven’t had a dilated eye exam in several years

At your visit, consider asking:

• Do I have signs of AMD? If so, what type and stage?
• How often should I come back for checkups?
• Are AREDS2 supplements appropriate for me?
• What lifestyle changes would help my eyes the most?
• At what point should we consider low-vision rehabilitation?

And remember: this article is for education, not a diagnosis or treatment plan.
Only a qualified eye care professional who has examined you can give medical
advice specifically tailored to your situation.

Bottom line

Age-related macular degeneration can sound intimidating, but understanding it is
the first step toward managing it. By recognizing symptoms early, staying on top
of eye appointments, embracing treatments like anti-VEGF injections when needed,
and building an eye-healthy lifestyle, you give your macula the best chance to
keep doing its job for as long as possible.
