Dry AMD vs Wet AMD
Age-related macular degeneration comes in two forms, dry and wet. They share symptoms but differ in how they develop, how fast they move, and how they are treated. Knowing which is which, and what warning signs to watch for, helps you protect your central vision.
Key Takeaways
- AMD has two forms, dry and wet, and they differ in cause, speed, and treatment.
- Dry AMD is the large majority of cases and progresses slowly through early, intermediate, and late stages.
- Wet AMD is less common but more serious, with abnormal blood vessels that leak and can damage central vision quickly.
- Any stage of dry AMD can turn into wet AMD, which is why ongoing monitoring matters.
- Wet AMD is treatable, especially when caught early, so sudden central vision changes need prompt care.
- A dilated eye exam diagnoses and tracks both forms, and an Amsler grid helps you watch for changes at home.
Quick Answer: dry vs wet AMD
Dry AMD is the slow, common form, where the macula gradually thins and small deposits called drusen build up. Wet AMD is the less common, faster form, where abnormal blood vessels grow under the retina and leak fluid or blood. Dry AMD is managed with nutrition, lifestyle, and monitoring. Wet AMD is treated with injections. Any dry AMD can turn into wet, so if straight lines suddenly look wavy, see an eye doctor right away.
Dry AMD (Atrophic)
Dry AMD is the most common form, accounting for the large majority of cases. It happens as the macula slowly thins with age and yellow deposits called drusen build up beneath the retina. It moves through three stages: early, which usually has no symptoms; intermediate, where some people notice mild blur or trouble in low light; and late, where central vision can become blurry or develop blank spots. The advanced stage of dry AMD is sometimes called geographic atrophy. Dry AMD usually progresses slowly over years, and it is managed with nutrition, healthy habits, and regular monitoring.
Wet AMD (Neovascular)
Wet AMD is less common but more serious, and it is always a late stage of the disease. It happens when abnormal blood vessels grow under the retina and leak fluid or blood, which can damage the macula quickly and cause faster vision loss than dry AMD. The good news is that treatment options are available. Wet AMD is usually treated with anti-VEGF medicines that an eye doctor injects into the eye, and in some cases photodynamic therapy, a combination of injections and laser. Treatment works best when it starts early, which is why sudden changes should never wait.
Dry vs Wet AMD at a Glance
| Feature | Dry AMD | Wet AMD |
|---|---|---|
| How common | The large majority of cases | Less common |
| What happens | Macula thins; drusen build up | Abnormal vessels leak fluid or blood |
| Speed | Slow, over years | Can be fast |
| Stages | Early, intermediate, late | Always late stage |
| Treatment | Nutrition, lifestyle, monitoring; no treatment yet for late dry AMD | Anti-VEGF injections; sometimes photodynamic therapy |
| Urgency | Routine monitoring | Sudden changes need prompt care |

How Dry AMD Can Turn Into Wet AMD
Dry and wet AMD are not completely separate. Any stage of dry AMD can convert to wet AMD, sometimes suddenly. That is why monitoring is so important even if your AMD is mild and stable. The classic warning sign of a change is straight lines starting to look wavy or crooked, or a new blurry or blank spot near the center of your vision. If that happens, contact your eye doctor right away, because catching wet AMD early gives treatment its best chance to preserve vision.
How Each Is Diagnosed and Tracked
Both forms are found and followed with a dilated eye exam, where your doctor widens your pupils to look at the retina. An imaging test called optical coherence tomography (OCT) takes detailed pictures of the macula and can reveal fluid from wet AMD or thinning from dry AMD. At home, many people use an Amsler grid, a simple square chart, to check their central vision regularly between visits. Early AMD often has no symptoms, so regular exams remain the most reliable way to stay ahead of it.
Dry Eye Rescue Tip
Test one eye at a time. Because your two eyes cover for each other, you can miss an early change if you only look with both eyes open. Cover one eye, focus on a fixed point or an Amsler grid, then switch. Catching a small change in a single eye is exactly how people catch wet AMD early.

Frequently Asked Questions
What is the main difference between dry and wet AMD?
Dry AMD is a slow thinning of the macula with drusen deposits. Wet AMD involves abnormal blood vessels that leak under the retina and can damage vision quickly. Wet AMD is less common but more serious.
Which type is more common?
Dry AMD is far more common, making up the large majority of cases. Wet AMD is less common but causes a larger share of serious vision loss.
Can dry AMD turn into wet AMD?
Yes. Any stage of dry AMD can convert to wet AMD, sometimes suddenly, which is why ongoing monitoring is important even when AMD seems mild.
What is the warning sign of wet AMD?
Straight lines suddenly looking wavy or crooked, or a new blurry or blank spot in your central vision. If this happens, see your eye doctor right away.
How is each type treated?
Dry AMD is managed with nutrition, lifestyle, and monitoring, and there is no treatment yet for late dry AMD. Wet AMD is treated with anti-VEGF injections and, in some cases, photodynamic therapy.
What is geographic atrophy?
Geographic atrophy is the advanced stage of dry AMD, where areas of the macula have thinned and lost function, leading to blank spots in central vision.
How are dry and wet AMD diagnosed?
Through a dilated eye exam and often an OCT scan, which images the macula and can show fluid from wet AMD or thinning from dry AMD.
Can I monitor AMD at home?
Yes. Many people use an Amsler grid to check central vision between visits, testing one eye at a time. It helps catch changes, but it does not replace regular exams.
Where can I find a doctor for AMD?
Use the Dry Eye Rescue Doctor Locator to find an eye care professional near you for a dilated exam, diagnosis, and monitoring.
