The short answer
Macular degeneration (often called AMD) damages the macula — the small center part of the retina that gives you sharp, straight-ahead vision for reading and seeing faces. There are two types. Dry AMD is the most common and usually changes slowly. Wet AMD is less common and can take vision faster. Early AMD often has no signs, so a dilated eye exam is how it’s found. If straight lines suddenly look wavy, call your eye doctor right away.
Your central vision is the part you use to read a text message, recognize a friend across the room, or thread a needle. Macular degeneration affects exactly that part. The National Eye Institute calls it a leading cause of vision loss for older adults.
The good news: finding it early gives you and your eye doctor the most options. The hard part is that early AMD doesn’t hurt and often has no signs, so many people don’t know anything is wrong until it’s further along.
This guide explains what macular degeneration is, who’s most at risk, the warning signs to watch for, and the real options for slowing it down and protecting the sight you have.
Key Takeaways
- Macular degeneration damages the macula, the center part of the retina that gives you your sharpest vision.
- There are two main types: dry (most common, usually slower) and wet (less common, usually faster).
- Age, family history, smoking and being white (Caucasian) raise your risk.
- Early AMD often has no symptoms, so regular dilated eye exams matter.
- There’s no cure, but treatment can slow it — and for wet AMD, eye injections can help protect vision.
- Straight lines that suddenly look wavy are a warning sign. Call right away.
What Is Macular Degeneration?
Think of your eye like a camera. The retina is the film at the back that captures light, and the macula is the tiny bullseye at the very center. It’s packed with the cells that give you fine detail and color. When the macula breaks down, your central vision blurs or gets blank spots, while your side (peripheral) vision usually stays.
That difference matters. The National Eye Institute says AMD doesn’t cause complete blindness. But losing sharp central vision can make it harder to read, drive, see faces and do close-up work — which is why it affects everyday independence so much.
The most common form is age-related macular degeneration, or AMD. It builds up over many years, which is why it mostly shows up later in life.
What’s the Difference Between Wet and Dry Macular Degeneration?
Dry AMD (most common)
Most people with AMD have the dry type. The light-sensing cells in the macula slowly thin out, and small yellow deposits called drusen build up underneath. Vision loss is usually slow, over years. Dry AMD has early, middle (intermediate) and late stages. A late form called geographic atrophy can cause serious central vision loss.
Wet AMD (less common, usually faster)
In wet AMD, abnormal blood vessels grow under the retina and leak fluid or blood, which damages the macula. It usually causes faster vision loss — sometimes over days or weeks. Dry AMD can turn into wet AMD, so even a mild diagnosis needs regular checkups.
Who Is at Risk for Macular Degeneration?
The National Eye Institute says your risk is higher if you:
- Are 55 or older
- Have a family history of AMD
- Are white (Caucasian)
- Smoke
Smoking is the big one you can change. Quitting helps at any age. High blood pressure, high cholesterol and an unhealthy diet are also worth talking about with your doctor.
What Are the Symptoms of Macular Degeneration?
Early dry AMD usually doesn’t cause any symptoms. You can have it and feel like your vision is normal — which is why an exam can catch it before you would.
As it gets worse, watch for:
- Blurry or fuzzy central vision that glasses don’t fix
- Straight lines — door frames, blinds, tile lines — that look wavy or bent
- A dim, blurry or blank spot in the middle of what you’re looking at
- Colors that look less bright than they used to
- Needing more light to read, and more trouble in dim rooms
- Trouble recognizing faces
Straight lines look wavy? Call right away.
Straight lines that suddenly look wavy or crooked can be a sign of wet AMD, and wet AMD can’t wait. Don’t hold off until your next visit — call 727-738-5900.

How Is Macular Degeneration Diagnosed?
- Dilated eye exam. Drops widen your pupils so the doctor can look at the retina and macula. This can show drusen and other early changes long before you’d notice anything.
- OCT scan. A quick scan, like a detailed cross-section photo, that shows fluid, thinning and the layers of the retina. It’s also used to track AMD over time.
- Fluorescein angiography. Used if wet AMD is suspected. A dye is injected into a vein in your arm and travels to your eye, showing any leaking blood vessels.
- Amsler grid. A simple grid of straight lines with a dot in the center that you can check at home.
What Is an Amsler Grid and How Do I Use It?
An Amsler grid is a square of straight lines with a dot in the middle. It helps you notice changes in your central vision between visits.
- Keep it somewhere you’ll see it, like the fridge, in good light.
- Wear your reading glasses if you use them.
- Cover one eye and look at the center dot with the other. Then switch eyes.
- If lines look wavy, blurry, bent or missing — or if anything has changed since last time — call your eye doctor.
An Amsler grid doesn’t replace an eye exam. It’s a way to catch changes sooner.
How Is Macular Degeneration Treated?
There’s no cure for macular degeneration, so be careful with any product that promises one. But there are treatments, and the right one depends on which type and stage you have.
Dry AMD
For intermediate dry AMD, the National Eye Institute says special dietary supplements (a specific mix of vitamins and minerals, known as the AREDS2 formula) may be able to stop it from turning into late AMD. These aren’t ordinary multivitamins, and they aren’t right for everyone — ask your eye doctor before starting them.
For geographic atrophy, a late form of dry AMD, newer eye injection treatments are now available for some people. Your eye doctor can tell you whether they fit your eyes.
Beyond that, managing dry AMD is about regular checkups, home monitoring and healthy habits.
Wet AMD
The main treatment for wet AMD is medicine called anti-VEGF, which the doctor injects into the eye. It works by stopping the abnormal blood vessels from growing and leaking. The eye is numbed first. The injections are usually repeated on a schedule, and your doctor will explain what to expect for your eyes. Some people are also treated with photodynamic therapy, which combines an injection with a laser.
With wet AMD, speed and consistency matter. Starting treatment early and keeping every appointment are the most important things you can do.
How to Prevent Macular Degeneration: Ways to Lower Your Risk
You can’t change your age or your genes, but the National Eye Institute suggests these steps:
- If you smoke, quit. It’s one of the most important things you can do for your eyes. Free help: 1-800-QUIT-NOW.
- Get regular physical activity.
- Keep your blood pressure and cholesterol in a healthy range.
- Eat healthy foods, including leafy greens like spinach and kale, and fish.
Wearing sunglasses and a hat in the Florida sun is a good habit for your eyes too.
When Should You See an Eye Doctor?
Don’t wait for symptoms. A regular dilated eye exam is the best way to find macular degeneration early, especially if you’re over 55, have family with AMD, or smoke. Your eye doctor will tell you how often to come in.
Call soon if you notice new blur in the center of your vision, a dark or blank spot, or colors that seem washed out. Call right away if straight lines suddenly look wavy or bent.
Living With Macular Degeneration
A diagnosis doesn’t mean the end of the things you enjoy. Many people keep reading, cooking and doing their hobbies with the right tools and support.
Low-vision aids like magnifiers, large-print books and screen readers can help. Bright, even lighting helps at home, and simple contrast tricks — like a dark cutting board for light-colored foods — make daily tasks easier. Low-vision specialists and occupational therapists can teach practical strategies for your vision.
It’s normal to feel frustrated or worried about vision changes. Leaning on family, support groups and your care team helps.
Frequently Asked Questions
What is the difference between wet and dry macular degeneration?
Dry AMD is the most common type and usually changes slowly as the macula thins and deposits build up. Wet AMD is less common and usually takes vision faster, because abnormal blood vessels leak under the retina. Dry can turn into wet, so regular checkups matter either way.
Does macular degeneration cause blindness?
The National Eye Institute says AMD doesn’t cause complete blindness. It affects central vision but usually leaves side vision, so most people can still get around. The hard part is losing the sharp vision used for reading, driving and seeing faces.
Can macular degeneration be reversed or cured?
Not at this time. Damage that has already happened usually can’t be undone. But treatment can slow it down, and for wet AMD, eye injections can help protect the vision you have. Finding it early gives you the most options.
What does vision look like with macular degeneration?
Side vision usually stays, but the center gets blurry, dim or wavy. Straight lines like door frames may look bent. Some people see a blurry or blank spot in the middle of what they’re looking at, like a smudge on the center of a window. Faces and small print can get hard to make out.
What are AREDS2 vitamins, and should I take them?
AREDS2 is a specific mix of vitamins and minerals studied for people with intermediate AMD. The National Eye Institute says it may help stop intermediate AMD from turning into late AMD. It isn’t a general eye vitamin and isn’t meant for everyone — ask your eye doctor before you start.
What are eye injections for macular degeneration like?
Your eye is numbed first, and the injection itself is quick. The medicine helps stop abnormal blood vessels from growing and leaking. Most people need them on a regular schedule. Your doctor will walk you through each step before you start.
What happens if you stop eye injections for macular degeneration?
Don’t stop or skip injections without talking to your eye doctor first. Wet AMD can become active again when treatment stops, and vision that is lost may not come back. Your doctor may change how often you need injections based on how your eye responds.
Is macular degeneration hereditary?
Family history is a risk factor, so if a parent, brother or sister had AMD, your risk is higher. But genes aren’t the whole story — smoking and other habits matter too.
Can diet help macular degeneration?
A healthy diet with leafy greens and fish is one of the steps the National Eye Institute suggests. Diet isn’t a cure, but it’s part of taking care of your eyes.
I have wavy vision today. What should I do?
Call your eye doctor right away instead of waiting. Sudden wavy or bent straight lines can be a sign of wet AMD, and getting seen quickly matters. Call us at 727-738-5900.
