Macular Degeneration (AMD)

What Is Macular Degeneration?

The macula is the small central area of your retina — the tissue that lines the back of your eye. It’s responsible for your sharp, detailed central vision: the vision you use to read, recognize faces, drive, and see fine detail. The rest of your retina handles your peripheral (side) vision.

In AMD, the macula deteriorates over time. As it does, your central vision becomes blurry, distorted, or develops blank spots — while your peripheral vision typically stays intact. That’s why AMD doesn’t usually cause total blindness, but it can make everyday tasks like reading, driving, and seeing faces increasingly difficult.

Dry AMD vs. Wet AMD

There are two forms, and they behave very differently.

Dry AMD

Dry AMD is by far the more common form — about 85–90% of AMD cases. It happens when small yellow deposits called drusen accumulate under the retina, and the macular tissue gradually thins. Dry AMD usually progresses slowly, and many people with early dry AMD have minimal or no symptoms for years. In more advanced stages, it can cause noticeable central vision changes.

There is currently no medical treatment that reverses dry AMD. But that doesn’t mean nothing can be done — monitoring, nutritional supplementation, and lifestyle changes can make a meaningful difference in how the disease behaves over time. That’s where we come in.

Wet AMD

Wet AMD is less common but more urgent. It happens when abnormal blood vessels grow underneath the retina and leak fluid or blood, causing rapid damage to the macula. Wet AMD can cause sudden changes in vision — straight lines looking wavy, a dark spot appearing in your central vision, or a noticeable drop in clarity.

Wet AMD requires prompt treatment with injections (anti-VEGF medications) given by a retina specialist.

About 10–15% of people with dry AMD eventually develop wet AMD. That’s one of the most important reasons we monitor dry AMD patients regularly — so we can catch conversion early, when treatment is most effective.

How We Monitor Your AMD

If you have dry AMD, regular monitoring is the most important thing we can do. At your visits, we:

• Examine your macula — your doctor looks at the retina directly through a dilated pupil, checking for changes in drusen, pigment, or any signs of fluid that could indicate conversion to wet AMD.
• Check your vision — including how your central vision is functioning and whether there’s been any change.
• Retinal imaging when indicated — for intermediate or advancing AMD, we may use OCT (optical coherence tomography) to get detailed cross-sectional images of your macula. OCT lets us detect subtle structural changes long before you’d notice them yourself. Your doctor will let you know when imaging is appropriate for your stage.
• Review your Amsler grid — we’ll give you a simple grid to use at home between visits. It takes 30 seconds to check, and it’s one of the best early warning tools for detecting sudden changes.

How often you need to be seen depends on the stage and activity of your AMD. For early dry AMD, annual monitoring may be sufficient. For more advanced stages, we may want to see you every 3–6 months.

What You Can Do to Protect Your Vision

This is the conversation we have with every AMD patient, because the research is clear — there are things you can do that make a real difference.

AREDS2 vitamins

The Age-Related Eye Disease Study (AREDS2) showed that a specific combination of vitamins and minerals — vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin — can reduce the risk of intermediate dry AMD progressing to advanced AMD by about 25%. That’s significant. If you have intermediate or advanced dry AMD, we’ll recommend an AREDS2 formula and help you choose a quality supplement. (If you have early AMD, the evidence for supplementation is less clear, and we’ll talk through whether it makes sense for you.)

Diet

Don’t smoke

Smoking is one of the strongest modifiable risk factors for AMD. Smokers are 2–4 times more likely to develop AMD, and smoking accelerates progression. If you smoke, quitting is the single most impactful thing you can do for your macular health.

Protect your eyes from UV light

Wear sunglasses with UV protection when you’re outdoors. Cumulative UV exposure is a risk factor for AMD.

Exercise

Regular physical activity is associated with a lower risk of AMD progression. It also supports cardiovascular health, which matters because the macula depends on healthy blood flow.

Monitor your vision at home

We’ll give you an Amsler grid — a simple printed grid you check one eye at a time. If you ever notice the lines looking wavy, bent, or missing, call us that day. This is your early warning system for wet AMD conversion.

Your Vision Is More Than Your Retina

This is something we want every AMD patient to hear: even if you see a retina specialist, you still need a primary eye care team.

A retina doctor focuses on your retina — and if you have wet AMD, that relationship is essential. But your eyes have a lot more going on than your macula. You may also be developing cataracts. You may need your glasses updated. You may have glaucoma risk factors that need monitoring. You may have dry eye that’s affecting your comfort and quality of vision.

We manage all of that. We’re the team that looks at the whole picture — your vision, your eye health, your comfort, your daily function — and makes sure nothing gets missed while your retina doctor focuses on the macula.

Many of our AMD patients see us for their comprehensive eye care and a retina specialist for their AMD-specific treatment. That’s the right setup. We coordinate care, share imaging, and make sure everyone is on the same page. What we don’t want is for you to assume that because you see a retina doctor, you don’t need regular eye exams with us. You do — and for good reason.
