Age-related macular degeneration (AMD) comes in two forms. Dry AMD is far more common, making up about 85% of cases, and usually progresses slowly. Wet AMD accounts for about 15% but can cause faster, more serious vision loss because abnormal blood vessels leak under the retina. Both affect central vision, not side vision. Treatments differ: AREDS2 vitamins and newer injections for advanced dry AMD, and anti-VEGF injections for wet AMD.
Introduction
Your mom comes home from her eye exam and mentions that the doctor said “macular degeneration.” She isn’t sure which type of macular degeneration she has or whether she should be worried. You start searching online and quickly run into two terms: dry and wet.
Understanding dry vs. wet macular degeneration is one of the most helpful first steps after a diagnosis. The two types share a name and affect the same part of the eye, but they behave very differently. One tends to move slowly over years. The other can change vision in weeks and needs prompt treatment.
At Anaheim Eye Institute, our fellowship-trained retina specialists have helped Orange County families navigate AMD for decades. This guide explains each type in plain language, which symptoms deserve a quick call to the doctor, and what treatment options exist today, so you can have a more confident conversation at your next appointment.
What Is Macular Degeneration?
Age-related macular degeneration is an eye disease that damages the macula, the small central part of the retina responsible for sharp, straight-ahead vision. It does not cause total blindness, because side vision stays intact, but it can make reading, driving, and recognizing faces difficult.
The retina lines the back of your eye and works like the film in a camera. The macula sits at its center and handles fine detail: reading small print, threading a needle, or seeing the expression on someone’s face.
The American Academy of Ophthalmology describes AMD as a leading cause of vision loss in people over 50. It usually affects both eyes, though often unevenly, so one eye may compensate for the other for a while.
Every person with AMD starts with the dry form. Some people later develop the wet form in one or both eyes. That is why understanding both types matters, even if you’ve only been told you have dry AMD.
Dry Macular Degeneration: Slow and Most Common
Dry macular degeneration is the most common form, accounting for about 85% of AMD cases. It happens when the macula gradually thins with age and small yellow deposits called drusen build up beneath the retina. Vision changes usually develop slowly over many years.
The American Society of Retina Specialists outlines dry AMD in three stages:
- Early AMD: Small to medium drusen are present. Most people have no noticeable symptoms, and it is typically found during a routine exam.
- Intermediate AMD: Drusen become larger, and pigment changes may appear. Some people notice mild blur or need more light to read.
- Late dry AMD (geographic atrophy): Patches of retinal tissue waste away, creating blind spots in central vision. These areas usually start next to the very center of the macula and can expand into it over time.
Not everyone with dry early AMD progresses to later stages. Many people keep useful vision for life, especially with regular monitoring.
Wet Macular Degeneration: Less Common, Faster Moving
Wet macular degeneration makes up about 15% of AMD cases but is responsible for much of the severe vision loss linked to the disease. It occurs when abnormal blood vessels grow under the retina and leak fluid or blood, distorting and damaging the macula.
Doctors also call wet AMD “neovascular” AMD, which simply means new blood vessel growth. These vessels are fragile. When they leak, the macula swells and lifts, which can quickly blur or warp central vision.
Unlike dry AMD, wet AMD can cause noticeable changes over days or weeks. If left untreated, scarring and permanent central vision loss can occur.
The encouraging news is that wet AMD is very treatable when caught early. Modern injection therapy has changed the outlook for many patients, helping them keep and sometimes even improve their vision.
Every case of macular degeneration begins as dry, which is why regular monitoring is important even when vision seems stable.
Dry vs. Wet Macular Degeneration Symptoms
Symptoms overlap between the two types, but the speed of change is often the most significant clue. Dry AMD tends to cause gradual changes. Wet AMD more often causes sudden distortion or blur.
Common AMD symptoms include:
- Blurry or fuzzy central vision, especially when reading
- Straight lines looking wavy or bent, like door frames or lines on a page
- A dark, blurry, or empty spot in the center of your vision
- Needing brighter light for close-up tasks
- Colors seeming less vivid
- Trouble recognizing faces at a normal distance
Wavy or distorted lines are a particular red flag for wet AMD. If they appear suddenly or worsen quickly, call your eye doctor promptly rather than waiting for your next routine visit.
Using an Amsler Grid at Home
Many retina specialists recommend an Amsler grid, a simple chart of straight lines with a dot in the center. You check each eye separately, with your reading glasses on, while looking at the dot.
If lines appear wavy, broken, or missing, or if a new dark area shows up, contact your eye doctor. The grid isn’t a substitute for an exam, but it can help you notice changes between visits.
Macular Degeneration Treatment Options for Each Type
Macular degeneration treatment depends on the type and stage. There is no cure yet, but today’s treatments can slow progression. For dry AMD, options include AREDS2 vitamins and newer injections for geographic atrophy. For wet AMD, anti-VEGF eye injections are the standard of care.
Treating Dry AMD
AREDS2 supplements. A specific vitamin and mineral formula, studied in the National Eye Institute’s AREDS2 trial, contains vitamins C and E, lutein, zeaxanthin, zinc, and copper. For people with intermediate AMD, or late AMD in one eye, it may lower the risk of progressing to advanced disease. It is not recommended as a preventive for people without AMD, and it does not help early AMD, so speak with your doctor before starting.
Treatments for geographic atrophy. In 2023, the FDA approved two medications for geographic atrophy: Syfovre (pegcetacoplan) and Izervay (avacincaptad pegol). Both are injected into the eye, typically every one to two months. They don’t restore lost vision, but they can slow how quickly the damaged areas grow.
Treating Wet AMD
Anti-VEGF injections. VEGF is a protein that signals the eye to grow new blood vessels. Anti-VEGF medications block that signal, which helps stop leaking and shrink abnormal vessels. The National Eye Institute’s overview of wet AMD treatments notes that these injections are the main treatment and can help many people keep their vision.
The idea of an eye injection worries many patients, and that’s understandable. The eye is fully numbed first, and the injection itself takes only seconds. Treatment typically begins on a monthly basis, and as the eye stabilizes, many patients are able to gradually increase the interval between visits.
Our retina specialists provide these treatments in-house. You can learn more about our approach on our retinal disease and surgery page.
Wet macular degeneration is very treatable when caught early, and many patients keep reading and driving for years.
Risk Factors You Can and Can’t Control
Some AMD risk factors are out of your hands, but others are within your control. Knowing both helps you and your eye doctor decide how closely to monitor your eyes.
Risk factors you can’t change:
- Age: Risk rises significantly after 50 and continues climbing with each decade.
- Family history: Having a parent or sibling with AMD increases your risk.
- Genetics and ancestry: AMD is more common in people of European descent.
Risk factors you can influence:
- Smoking: This habit is one of the strongest controllable risk factors. Quitting at any age helps.
- Diet: Leafy greens, colorful vegetables, and fish rich in omega-3s support eye health.
- Blood pressure and cholesterol: Keeping these in a healthy range supports blood vessel health in the eye.
- Sun protection: Wearing UV-blocking sunglasses is a smart habit, especially under the Southern California sun.
- Regular eye exams: Routine dilated exams catch AMD early, often before you notice symptoms.

Conclusion
The main difference between dry and wet macular degeneration is speed and cause. Dry AMD is common and usually slow, while wet AMD is less common but can change vision quickly due to leaking blood vessels. Whichever type you or a loved one has, regular exams and prompt attention to new symptoms make a real difference.

Frequently Asked Questions
Which is worse, dry or wet macular degeneration? Wet macular degeneration generally causes faster and more severe vision loss because leaking blood vessels damage the macula quickly. However, late-stage dry AMD (geographic atrophy) can also cause significant central vision loss over time. Both types benefit from regular monitoring by an eye doctor.
Can dry macular degeneration turn into wet AMD? Yes. All AMD begins as the dry form, and some people later develop wet AMD in one or both eyes. Sudden wavy lines or new blurry spots can be a sign of this change and should be checked promptly.
Does macular degeneration cause total blindness? AMD typically affects central vision while leaving side (peripheral) sight intact. Even in advanced cases, most people can still get around using their peripheral vision. However, central vision loss can make reading, driving, and recognizing faces difficult.
Are eye injections for wet AMD painful? Most patients say the injections are much easier than they expected. The eye is thoroughly numbed beforehand, and the injection itself takes only a few seconds. Some people feel mild pressure or scratchiness afterward that fades within a day.
Should I take AREDS2 vitamins if I have macular degeneration? AREDS2 supplements are recommended mainly for people with intermediate AMD or late AMD in one eye, where research shows they may slow progression. They haven’t been shown to help early AMD or prevent the disease. Ask your eye doctor whether they make sense for your stage.
