AMD Stages
Understanding AMD Stages
We use a staging system to describe how far AMD has progressed in your eyes. The system looks at the size and number of drusen, which are yellow deposits under your retina, and whether there are changes in the pigment layer of your macula.
Staging lets us predict your risk of vision loss and choose the best monitoring or treatment plan. The three main stages are early, intermediate, and late AMD, with late AMD divided into dry and wet types.
AMD typically begins with small drusen that do not affect your vision. Over months or years, drusen can grow larger or increase in number, and your retina may develop pigment changes.
Not everyone with early AMD moves to late AMD. Some people stay at early or intermediate stages for many years, while others progress more quickly depending on their genes, lifestyle, and other risk factors.
Different stages call for different actions. Early AMD may need only lifestyle changes and regular monitoring, while intermediate AMD often benefits from special vitamins.
- Late dry AMD may be treated with newer therapies to slow cell loss
- Late wet AMD requires injections to stop abnormal blood vessels
- Your stage determines how often we schedule follow-up exams
- Knowing your stage helps you recognize warning signs that need urgent attention
Certain vision changes require same-day evaluation because they may signal rapid progression or complications. Contact our office immediately if you notice any of these warning signs, and if symptoms are severe or occur after hours, seek emergency eye care.
- Straight lines suddenly look wavy, bent, or distorted, especially if this is new or rapidly worsening
- A new dark spot, blank area, or shadow appears in your central vision
- Vision in one eye drops suddenly over hours or days
- You see new flashes of light, a shower of floaters, or a curtain or veil blocking part of your vision
- After an injection, you have increasing pain, worsening redness, light sensitivity, or discharge
Early AMD (Drusen Without Vision Loss)
In early AMD, small or medium-sized drusen appear under your retina. These deposits form when waste products build up between the retina and the layer of blood vessels that nourish it.
Your macula, the part of the retina responsible for sharp central vision, can still function normally at this stage. Most people do not notice changes in their eyesight during early AMD.
Early AMD usually causes no symptoms. You might read, drive, and see faces without any trouble.
- Your vision may remain 20/20 or close to it
- Colors and contrast typically appear normal
- You may have no awareness that anything is wrong until an eye exam
- Drusen are detected only when we look inside your eye with special instruments
Certain factors make it more likely that early AMD will advance to later stages. Age over 60, smoking, and a family history of AMD increase your risk.
Other factors include high blood pressure, obesity, and a diet low in fruits and vegetables. Some research suggests that sun exposure may play a role, though it is less established than smoking and genetics. Knowing your risk factors helps you take steps to slow progression.
We typically recommend eye exams once a year if you have early AMD. During each visit, we dilate your pupils and examine your retina to check for changes in drusen or new pigment abnormalities.
Photographs of your retina and optical coherence tomography scans let us compare your eyes over time. If we see signs of progression, we may increase the frequency of your visits.
Making healthy choices can help protect your vision. Quitting smoking is the single most important step you can take to lower your risk of AMD progression.
- Eat leafy greens, fish rich in omega-3 fatty acids, and colorful fruits and vegetables
- Maintain a healthy weight and stay physically active
- Control your blood pressure and cholesterol
- Wear sunglasses that block ultraviolet light when outdoors; some people also choose blue-light filtering, though the benefit for AMD is not yet established
- Keep your blood sugar stable if you have diabetes
Intermediate AMD (Larger Drusen or Pigment Changes)
Intermediate AMD is diagnosed when we find large drusen or many medium-sized drusen in your macula. We may also see clumping or loss of pigment in the retinal pigment epithelium, the layer that supports your photoreceptor cells.
These changes indicate a higher risk of progressing to late AMD. At this stage, your retina is under more stress, and waste removal is less efficient than in early AMD.
Some people with intermediate AMD begin to notice subtle changes in their vision. You might need brighter light for reading or notice that it takes longer for your eyes to adjust when you move from bright sunlight to a dim room.
- Straight lines may start to appear slightly wavy or distorted
- You may see a small blurry or gray spot in your central vision
- Colors might seem less vivid than before
- Fine details may become harder to see
If straight lines become newly wavy or the distortion rapidly worsens, contact us urgently to rule out wet AMD.
We use several tests to confirm intermediate AMD and monitor your macula closely. Optical coherence tomography creates cross-sectional images that show drusen and thinning of retinal layers.
Fundus photography captures detailed color pictures of your retina, and autofluorescence imaging highlights areas of pigment change. If we suspect fluid or new blood vessels, we may order fluorescein angiography or OCT angiography.
If you have intermediate AMD in one or both eyes, or late AMD in one eye, we may recommend AREDS2 vitamins. This specific formula contains vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin.
Large research studies have shown that AREDS2 vitamins can reduce the risk of progression to late AMD by about 25 percent. Not all vitamin supplements are the same, so we suggest choosing a formula that matches the AREDS2 study doses.
AREDS2 vitamins reduce the risk of progression in people with intermediate or advanced AMD, but they do not cure AMD, restore lost vision, or prevent AMD from starting in people without the disease. These vitamins are not typically recommended for early AMD unless your eye doctor advises otherwise.
- Choose a true AREDS2 formula without beta-carotene, especially if you are a current or former smoker
- Discuss the supplement with your eye doctor to check for interactions with medications or medical conditions
- High-dose vitamins can cause side effects, so follow the recommended dose
We recommend that you check your vision regularly using an Amsler grid, a simple chart with a grid of straight lines. Many people test daily or several times per week. Testing each eye separately helps you detect new distortion or blank spots early.
- Use the grid in good lighting while wearing your reading glasses
- Cover one eye and focus on the center dot
- Notice if any lines look wavy, broken, or missing
- Contact our office immediately if you see new changes
Late AMD: Geographic Atrophy (Dry)
Geographic atrophy is a type of late dry AMD where patches of retinal cells die and leave areas of permanent vision loss. These areas of atrophy often start small and grow larger over time.
Because the macula is damaged, your central vision becomes blurry or develops blind spots. The outer parts of your retina usually remain healthy, so you keep your peripheral vision for navigation and movement.
People with geographic atrophy often notice a gradual decline in vision. You may struggle to recognize faces, read small print even with glasses, or see details when looking straight ahead.
- A gray or blank area may appear in the center of your vision
- Straight lines might look distorted or broken
- You need much brighter light for tasks like reading or cooking
- Colors may appear washed out or faded
- If you suddenly notice new distortion or a new dark spot in your central vision, it may signal wet AMD and needs urgent evaluation the same day. A curtain or shadow blocking your vision, or new flashes and floaters, can indicate a retinal tear, detachment, or bleeding, which also requires immediate care
As of 2025, newer treatments are available that may slow the growth of geographic atrophy. These therapies target complement proteins, which are molecules that contribute to inflammation and cell death in the retina.
We may recommend injections given every one to two months. Studies show these treatments can slow the expansion of atrophic areas, but the benefit is modest and varies from person to person. The injections do not restore lost vision and do not stop the disease completely.
- A key risk of these injections is an increased chance of developing wet AMD, so ongoing monitoring is essential
- As with any injection into the eye, there is a small risk of infection, inflammation, bleeding, or retinal problems
- Your eye doctor will discuss whether the potential benefit outweighs the risks in your case
Low vision aids and simple changes at home can help you maintain independence. Magnifiers, large-print books, high-contrast labels, and talking devices make daily tasks easier.
- Use task lighting and reduce glare with adjustable lamps
- Try electronic magnifiers or smartphone apps that enlarge text
- Consider audio books and voice-activated technology
- Work with a low vision specialist to find the best aids for your needs
Late AMD: Wet (Neovascular) AMD
Wet AMD happens when your retina does not get enough oxygen and nutrients from its normal blood supply. In response, your eye grows new blood vessels under or within the retina.
These new vessels are fragile and leak fluid or bleed, causing rapid damage to the macula. A protein called vascular endothelial growth factor, or VEGF, drives this abnormal blood vessel growth.
Wet AMD can cause vision to drop quickly, sometimes over just days or weeks. If you notice any sudden changes, contact our office the same day or go to an emergency eye clinic.
- Straight lines suddenly appear very wavy or bent
- A dark or blurry spot appears in your central vision
- Colors look washed out or you have trouble seeing contrast
- Words on a page seem to disappear or jumble together
- One eye has much worse vision than it did a few days ago
The main treatment for wet AMD is anti-VEGF injections, which block the VEGF protein and stop abnormal blood vessels from leaking. We perform these injections in our office using numbing drops and careful sterile techniques.
Most people feel only mild pressure during the injection, which takes just a few seconds. After the injection, you may notice some expected effects that are not dangerous.
- A scratchy or gritty sensation, like something is in your eye
- Mild tearing or watering
- A small red or bloodshot spot on the white of your eye
- Temporary floaters or spots in your vision
Serious complications are rare, but you should contact our office the same day if you develop any of these warning signs. If symptoms are severe or occur after hours, seek emergency eye care.
- Pain that gets worse instead of better
- Redness that increases over time
- Sensitivity to light
- Discharge from your eye
- Sudden drop in vision
Many treatment plans start with monthly injections for the first one to three doses, depending on the medication and how your retina responds. After that, we tailor your schedule based on OCT scans that check for fluid at each visit.
Some people continue monthly injections, while others switch to injections every two or three months. A few patients can extend their treatment interval even longer if their retina stays dry and stable.
If anti-VEGF injections do not fully control the fluid, we may add or switch to a different anti-VEGF medication. Combining medications or adjusting the treatment interval can sometimes improve results.
- Photodynamic therapy may be considered in specific cases for certain lesion types
- Laser treatment is rarely used now because it causes scarring
- Clinical trials may offer access to new drugs or combination therapies
- Low vision rehabilitation helps you make the most of your remaining sight
Frequently Asked Questions
No, many people with early AMD never develop late AMD. Your risk of progression depends on your stage, the number and size of drusen, your genetics, and lifestyle factors such as smoking and diet.
With regular monitoring and healthy lifestyle choices, some people remain stable at early or intermediate stages for many years or even the rest of their lives.
Yes, dry AMD can convert to wet AMD at any time, even if you have been stable for years. Wet AMD can develop suddenly, which is why regular Amsler grid checks and eye exams are so important.
The conversion usually happens when abnormal blood vessels start to grow beneath the retina. Catching this change early improves the chances of preserving vision with treatment.
Yes, some people develop both geographic atrophy and wet AMD in the same eye. This is called mixed or combined AMD.
Each condition is monitored and treated separately, so you may need both low vision support for atrophy and injections for wet AMD.
Yes, clinical studies have shown that complement inhibitor injections for geographic atrophy can increase the risk of developing wet AMD. Because this risk is significant, your eye doctor will monitor you closely with regular exams and imaging.
If wet AMD does develop, it can be treated with anti-VEGF injections. Early detection through monitoring helps preserve vision.
Early AMD usually requires yearly exams, intermediate AMD every six to twelve months, and late AMD every one to three months depending on treatment. We customize your schedule based on your specific risk and whether you are receiving injections.
If you notice any sudden vision changes between scheduled visits, contact us right away for an urgent evaluation.
Yes, researchers are studying new treatments to slow or reverse AMD at all stages. Clinical trials may offer access to experimental drugs, devices, or nutritional supplements not yet available to the general public.
Participating in a trial helps advance science for future patients and may give you access to promising new therapies. Ask your eye doctor whether any trials are appropriate for your stage and situation.
