Wet (Neovascular) AMD
Understanding Wet AMD and How It Differs from Dry AMD
In wet AMD, fragile new blood vessels begin to grow beneath the macula, the central part of your retina responsible for sharp, straight-ahead vision. These vessels are abnormal and weak, so they leak fluid and blood into the delicate layers of your retina. When fluid accumulates, it lifts and damages the macula, causing vision to become blurry or distorted.
Over time, this leaking and swelling can create scar tissue that permanently harms your central vision. Quick diagnosis and treatment are essential to stop further damage.
Dry AMD develops slowly as cells in the macula break down over many years. Wet AMD, by contrast, involves the sudden growth of leaky blood vessels that can damage your vision in weeks or months. About 10 to 15 percent of people with dry AMD will eventually develop the wet form.
We watch patients with dry AMD closely because catching the transition to wet AMD early gives us the best chance to protect your remaining vision.
The term 'neovascular' means 'new blood vessel.' In this condition, your eye mistakenly sends signals that trigger fresh blood vessel growth where it does not belong. These new vessels are the hallmark of wet AMD and the main target of our treatments.
Understanding this term helps you recognize why stopping new vessel growth is central to managing wet AMD.
Wet AMD can worsen rapidly, sometimes over just a few days or weeks. You might notice sudden changes like wavy lines, dark spots, or difficulty reading. Because progression is often swift, we treat wet AMD as an urgent condition that needs immediate attention.
Early treatment can slow or even stop the disease from advancing, which is why we encourage you to contact us the moment you notice any vision changes.
Warning Signs and Symptoms of Wet AMD
One of the earliest and most common signs of wet AMD is seeing straight lines bend, buckle, or appear wavy. You might notice this when looking at window frames, door edges, or lines of text. This distortion happens because fluid under your macula disrupts the normal arrangement of light-sensing cells.
If straight lines suddenly look crooked, call our office right away for an urgent evaluation.
Many people with wet AMD develop a gray, dark, or blank area in the center of their vision. This spot may make it hard to recognize faces, read, or see fine details. The blank area occurs where leaking fluid and bleeding have damaged the macula.
Central blind spots can appear suddenly and worsen quickly without treatment.
Wet AMD can reduce the vibrancy and contrast of colors. Reds may look less bright, or everything may seem faded and gray. This happens because the damaged macula cannot process color information as effectively.
While color changes alone are not always alarming, combined with other symptoms they suggest you should schedule an appointment soon.
If you experience a rapid drop in vision, especially in one eye, treat it as an emergency. Large bleeds or extensive fluid leakage can cause abrupt vision loss. Immediate care may help limit permanent damage.
For noticeable new distortion or a sudden central dark spot, contact us for same-day urgent evaluation. For profound or complete vision loss, particularly if accompanied by neurologic symptoms such as weakness, speech difficulty, or confusion, or if you cannot reach eye care promptly, go to the emergency room or call emergency services.
Risk Factors for Developing Wet AMD
Your risk of wet AMD rises sharply after age 60. Genetics also play a major role. If a parent or sibling has macular degeneration, your own risk increases significantly. We cannot change your age or family history, but knowing these risk factors helps us monitor you more closely.
Regular eye exams become even more important if you have relatives with AMD.
Smoking is one of the strongest controllable risk factors for wet AMD. Smokers are several times more likely to develop the disease than non-smokers. Conditions that affect your blood vessels, such as high blood pressure and high cholesterol, also raise your risk.
Quitting smoking and managing cardiovascular health can lower your chances of developing wet AMD and slow its progression if you already have it.
Wet AMD typically develops in the setting of underlying AMD, often following dry AMD changes, though it may be diagnosed without a prior dry AMD diagnosis. If you have been diagnosed with dry AMD, especially the intermediate or advanced form, you face a higher risk of converting to the wet type. We will teach you how to monitor your vision at home so you can catch the transition early.
Regular follow-up visits allow us to detect changes before you notice major symptoms.
Diets low in leafy greens, fish, and colorful vegetables may increase your AMD risk. Long-term ultraviolet light exposure may be associated with higher AMD risk, though the relationship is not fully established. Wearing UV-protective sunglasses is a sensible general eye-health measure. Obesity and lack of exercise are additional risk factors linked to inflammation and poor circulation.
Making healthier lifestyle choices supports your overall eye health and may reduce disease progression.
How We Diagnose Wet AMD
We start by checking your vision and examining the back of your eye with specialized lenses and lights. During this exam, we look for signs of abnormal blood vessels, fluid, or bleeding in your macula. Your symptoms and medical history also guide our evaluation.
A thorough exam helps us distinguish wet AMD from other conditions that cause similar vision problems.
Optical coherence tomography, or OCT, is a quick, painless scan that creates detailed cross-sectional images of your retina. It shows us exactly where fluid has collected and how much swelling is present. OCT is one of our most important tools for diagnosing wet AMD and tracking how well treatment is working.
We often repeat OCT scans at follow-up visits to monitor changes over time.
For this test, we inject a yellow dye called fluorescein into a vein in your arm. As the dye travels through your bloodstream, a special camera takes rapid photos of your retina. The images reveal where abnormal blood vessels are leaking and help us pinpoint the exact location and type of new vessel growth.
The dye temporarily causes your skin and urine to appear yellow or orange for up to 24 hours. Some people experience mild nausea. Allergic reactions are rare but can occur, so let us know if you have a history of dye reactions, asthma, or allergies before the test.
We may use this test when planning certain treatments or if OCT results are unclear.
The Amsler grid is a simple chart with a pattern of straight lines and a central dot. By covering one eye and looking at the grid, you can spot distortions or blank areas in your vision. We may give you a copy to use at home between appointments.
Checking the grid regularly helps you notice changes early so you can alert us right away.
Treatment Options for Wet AMD
Anti-VEGF medicines block a protein called vascular endothelial growth factor, which signals your eye to grow new blood vessels. By stopping this protein, we can halt the growth of abnormal vessels and reduce leakage. Injections are given directly into your eye and represent the current standard first-line treatment for wet AMD.
Most patients need repeated injections over months or years to keep the disease under control.
We numb your eye with drops and clean the surface thoroughly to prevent infection. The actual injection takes only a few seconds, and most people feel little to no pain. You may notice mild pressure or a brief sting.
You can usually go home shortly after the procedure, though you may need someone to drive you. Some practices may prescribe antibiotic drops, but the most important step is to watch for symptoms and contact us if you notice any warning signs.
While anti-VEGF injections are generally well tolerated, they do carry risks. These include infection inside the eye, inflammation, retinal tear or detachment, bleeding in the eye, temporary rise in eye pressure, and rare systemic risks such as blood clots or stroke. Serious complications are uncommon, but early recognition is important.
After your injection, knowing what is normal and what requires urgent attention helps you respond appropriately.
- Common and expected: scratchy or gritty feeling, mild irritation
- Common and expected: small red or bloodshot area on the white of your eye, a few new floaters
- Call us urgently if you have: worsening or severe pain
- Call us urgently if you have: increasing redness, vision getting worse, or increased light sensitivity
- Call us urgently if you have: pus or discharge from your eye
Some patients receive injections on a fixed schedule, such as every four to eight weeks. Others follow a treat-and-extend approach, where we gradually lengthen the time between injections if your condition stays stable. We tailor the schedule to your specific response and disease activity.
Regular follow-up exams and imaging help us decide when your next injection is needed.
Photodynamic therapy combines a light-sensitive drug with a special laser to seal abnormal blood vessels. We reserve this treatment for certain uncommon types of wet AMD or when anti-VEGF injections alone are not enough. It is less commonly used than it was in the past because injections are generally more effective.
If you receive photodynamic therapy, you will need to avoid bright light and direct sunlight for a period after treatment because the medication makes your skin temporarily sensitive to light.
We will discuss whether this option is right for you if your case has unique features.
Newer anti-VEGF medications and sustained-release devices are designed to last longer, reducing the number of injections you need each year. Some of these longer-acting options are now available for selected patients, and ongoing research continues to improve treatment convenience and outcomes.
Gene therapies and other innovative approaches are being studied in clinical trials but are not yet part of routine standard care. We stay current on the latest advances to offer you the best available evidence-based treatment and can discuss investigational options if appropriate.
Managing Your Vision and Daily Life with Wet AMD
Checking your vision daily with an Amsler grid or by simply noticing how straight lines look can help you catch new problems early. Always test each eye separately by covering the other. If you see new distortions, blank spots, or blurriness, contact our office immediately.
Early detection of changes allows us to adjust your treatment before permanent damage occurs.
Eating a diet rich in leafy greens, fish high in omega-3 fatty acids, and colorful fruits and vegetables supports your macula. We may recommend a specific vitamin and mineral supplement formulated for AMD, especially if you have intermediate or advanced disease. These supplements are typically based on the AREDS2 research and are not appropriate for everyone with AMD.
If you are a current or former smoker, you should avoid supplements containing beta-carotene due to increased lung cancer risk. Always review any supplements with us before starting them, as they can interact with medications or affect certain medical conditions such as kidney disease.
- Choose dark leafy greens like spinach and kale
- Include fish such as salmon or tuna at least twice a week
- Avoid smoking and limit alcohol to protect your eyes further
- Discuss AMD-specific supplements with us to ensure they are safe and appropriate for you
- If recommended, choose formulas without beta-carotene if you have ever smoked
If wet AMD has reduced your vision significantly, low vision specialists can teach you to use magnifiers, special lighting, and high-contrast materials. Electronic devices and smartphone apps can also enlarge text and improve your ability to read and navigate.
Rehabilitation services help you maintain independence and quality of life. We can refer you to a low vision specialist who will tailor tools and strategies to your needs.
Simple changes can make daily tasks safer and easier when you live with wet AMD.
- Install brighter lighting in reading areas and hallways
- Remove tripping hazards like loose rugs and clutter
- Use large-print labels and high-contrast markers
- Organize your space consistently so you can find items easily
- Join support groups for practical tips and emotional encouragement
Reach out immediately if you notice sudden worsening of distortion, new dark spots, or a drop in vision. Flashes of light or a curtain or shadow across your visual field may indicate a retinal tear or detachment and require same-day emergency evaluation. Pain, redness, or discharge after an injection also warrants urgent contact.
Do not wait for your next scheduled appointment if symptoms change. Quick communication allows us to intervene early and protect your sight.
Frequently Asked Questions
There is currently no cure for wet AMD, but treatment can stop or slow vision loss in many patients. Some people even regain a portion of lost vision with prompt, ongoing injections. The goal of therapy is to preserve as much functional vision as possible and prevent further damage.
Wet AMD affects your central vision but typically does not cause total darkness blindness. Your peripheral vision usually remains intact, allowing you to navigate and perform many daily activities. However, severe central vision loss can occur even with treatment, and outcomes vary based on how early treatment starts and how well the disease responds. With treatment and low vision aids, many people retain enough sight to maintain independence, though some will experience significant vision impairment.
Most patients report little to no pain during injections because we use numbing drops beforehand. You may feel brief pressure or a slight sting, but the discomfort is usually minimal and over quickly. Any soreness after the procedure is typically mild and short-lived.
Yes, if you develop wet AMD in one eye, your risk is higher for the other eye as well. We will monitor both eyes closely at every visit. Self-testing each eye separately at home helps you catch early signs in your second eye so we can start treatment right away.
Skipping or delaying injections can allow abnormal blood vessels to grow again and leak more fluid, leading to further vision loss. Staying on schedule gives you the best chance of preserving your sight. If you must miss an appointment, contact us as soon as possible to reschedule.
