Dry and Wet AMD
Understanding Dry and Wet AMD
Dry AMD is the more common form, affecting about 80 to 90 percent of people with macular degeneration. It develops when the macula, the central part of your retina responsible for sharp vision, begins to thin and break down over time. In its advanced stage, called geographic atrophy, patches of the macula waste away and enlarge over time.
- Light-sensitive cells in the macula slowly deteriorate
- Vision loss usually happens gradually over many years
- The condition may start in one eye and later affect the other
- Most people with dry AMD in early and intermediate stages maintain functional vision for daily tasks
Geographic atrophy can significantly impact reading and face recognition even when wet AMD has not developed.
Wet AMD occurs when abnormal blood vessels grow beneath the retina and leak fluid or blood. These vessels form because the eye tries to create new blood supply to the macula, but the new vessels are fragile and cause damage instead of helping.
This form is less common but more serious because it can cause rapid vision loss. We also call it neovascular AMD because of the new vessel growth involved.
The two types create distinct patterns of vision change. Dry AMD typically causes a slow blurring of central vision, making it harder to read or recognize faces over months or years.
Wet AMD often strikes more suddenly. You may notice straight lines appearing wavy, a dark or blank spot in your central vision, or colors seeming less bright. These changes can develop over days or weeks rather than years.
Yes, dry AMD can progress to the wet form in some people. About 10 to 15 percent of those with dry AMD will develop wet AMD in at least one eye.
- The risk increases with advanced dry AMD
- Wet AMD can develop even when dry AMD seems stable
- Having wet AMD in one eye raises the risk in the other eye
- Regular monitoring helps us catch this shift early
Recognizing Symptoms of Each Type
Early dry AMD often causes no noticeable symptoms at all. As the condition advances, you might need brighter light for reading or notice that it takes longer for your eyes to adjust when moving from bright to dim spaces.
Central vision may become slightly blurred or hazy. You might struggle to recognize faces from across a room or find that printed words look less crisp than before.
Drusen are small yellow deposits that form under the retina. We often spot them during routine eye exams before you notice any vision problems.
- A few small drusen are common with normal aging
- Larger or more numerous drusen signal higher AMD risk
- You cannot see or feel drusen yourself
- Only a dilated eye exam reveals these deposits
Wet AMD often announces itself with visual distortion. Straight lines such as doorframes, window blinds, or lines of text may suddenly appear bent or wavy.
A gray, dark, or blank area might appear in the center of your vision. Some people describe it as a smudge or cloud that will not clear. These symptoms mean fluid or blood is affecting the macula and require prompt attention.
Call our office right away if you experience sudden changes in your central vision. Any rapid increase in distortion, a new dark spot, or abrupt blurring needs same day or within 24 hours evaluation.
- Straight lines that suddenly look curved or broken
- A dark or empty patch blocking your central view
- Rapid worsening of blurriness over days
- Colors appearing washed out or less vibrant than usual
- Trouble reading even with your regular glasses
- New flashes of light, a sudden shower of floaters, or a curtain in your vision are separate emergencies that need same day care
Risk Factors for Dry and Wet AMD
Age is the single strongest risk factor for AMD. The condition rarely appears before 55, but risk climbs significantly after 60 and continues to rise with each passing decade.
If you have a parent or sibling with AMD, your own risk is higher. Certain genes increase susceptibility, though having these genes does not guarantee you will develop the disease. Family history helps us understand your personal risk profile.
Smoking doubles or even triples your risk of developing AMD and makes existing AMD worse. The harmful effects persist years after quitting, though stopping still offers significant benefits.
- High blood pressure strains the delicate blood vessels in your eyes
- High cholesterol may contribute to drusen formation
- Obesity increases inflammation that can damage the retina
- Heart disease and AMD share several common risk pathways
What you eat influences your retinal health. Diets low in colorful vegetables and omega-3 fatty acids may raise AMD risk, while diets rich in leafy greens and fish appear protective.
Prolonged exposure to bright sunlight over decades might increase risk, though the evidence is less clear than for other factors. Wearing sunglasses that block UV light is still a sensible precaution for overall eye health.
We do not fully understand why some people with dry AMD progress to the wet form while others do not. Advanced dry AMD with large drusen or pigment changes in the retina raises the likelihood.
Inflammation and oxygen deprivation in the retina may trigger the growth of abnormal blood vessels. Once wet AMD appears in one eye, the other eye faces increased risk as well.
How We Diagnose Dry and Wet AMD
A comprehensive dilated eye exam is essential for detecting AMD. We place drops in your eyes to widen the pupils, which gives us a clear view of the retina and macula.
Using special lenses and bright lights, we examine the back of your eye for drusen, pigment changes, or any signs of fluid or bleeding. The exam is painless, though your vision will be blurry and light-sensitive for a few hours afterward.
OCT is a quick, non-invasive imaging test that produces detailed cross-sectional pictures of your retina. Think of it like an ultrasound, but using light waves instead of sound.
- The scan takes only a few minutes per eye
- It reveals the layers of the retina in fine detail
- We can spot fluid, swelling, or thinning not visible otherwise
- Serial scans help us track changes over time
- OCT angiography (OCTA) can visualize abnormal blood vessels without dye
When we suspect wet AMD, fluorescein angiography helps pinpoint leaking blood vessels. We inject a yellow fluorescent dye into a vein in your arm, then take rapid photographs as the dye travels through the blood vessels in your retina.
The test shows exactly where abnormal vessels are located and whether they are actively leaking. This information guides treatment decisions and helps us monitor your response to therapy. Most people tolerate the test well, but brief nausea can occur and allergic reactions are rare. Your skin and urine may appear yellow for several hours.
Other imaging we may use includes OCT angiography, which shows blood flow without dye, and indocyanine green angiography to evaluate polypoidal choroidal vasculopathy or when fluorescein views are limited.
An Amsler grid is a simple chart with a pattern of straight lines and a central dot. We often give you one to use at home for daily self-monitoring.
By checking the grid with each eye separately, you can detect subtle changes in your central vision between office visits. If lines start to look wavy or areas go missing, contact us promptly so we can examine you.
- Wear your reading glasses and hold the grid at your normal reading distance
- Cover one eye at a time
- Use the same lighting and distance each time
- Note any new waviness, blurring, or missing areas and the date, then contact us promptly
Treatment Approaches for Each Type
For intermediate or advanced dry AMD, we may recommend a specific formula of vitamins and minerals based on the AREDS2 research study. This combination includes vitamin C, vitamin E, zinc, copper, and the carotenoids lutein and zeaxanthin. AREDS2 is recommended for intermediate AMD in one or both eyes or advanced AMD in one eye, not for early AMD or people without AMD.
These supplements can slow the progression of dry AMD in people who already have moderate disease. They do not cure AMD or restore lost vision, but they may help preserve the vision you still have. Not everyone needs these supplements, so ask us whether they are right for you.
- Do not start supplements without confirming you meet criteria
- Avoid formulas with beta-carotene if you are a current or former smoker
- High dose zinc can cause stomach upset or urinary issues. Copper is included to prevent anemia
- Supplements do not replace a healthy diet
Geographic atrophy (GA) is the advanced form of dry AMD. It causes well defined areas of retinal cell loss that expand over time, leading to central blind spots that make reading and face recognition difficult. GA does not involve fluid leakage like wet AMD.
Two intravitreal complement inhibitors can slow GA growth. Pegcetacoplan and avacincaptad pegol are given as repeated in office injections.
- These medicines slow the enlargement of atrophy. They do not restore lost vision
- Typical dosing: pegcetacoplan monthly or every other month; avacincaptad pegol monthly
- Possible side effects include increased risk of new or worsening wet AMD, intraocular inflammation, and transient eye pressure rises. Rare severe inflammation has been reported
- Call us right away if you notice new distortion, a sudden drop in central vision, severe eye pain, many new floaters, or worsening redness after an injection
- Suitability depends on the size and location of GA, your progression rate, and your goals. We will discuss expected benefit, risks, and visit frequency
Anti-VEGF medications are the primary treatment for wet AMD in 2025. These drugs block vascular endothelial growth factor, a protein that stimulates abnormal blood vessel growth. Common medicines include aflibercept, faricimab, ranibizumab, and off-label bevacizumab.
- We inject the medication directly into the eye in the office
- The procedure uses numbing drops and takes only a few minutes
- The medicine helps dry up leaking fluid and stop new vessel growth
- Most people tolerate the injections well with minimal discomfort
- Treatment can stabilize or even improve vision in many cases
Serious risks are uncommon but include infection inside the eye (endophthalmitis), retinal detachment, significant inflammation, bleeding, and sustained eye pressure rise. Call us the same day if you have severe eye pain, worsening redness, many new floaters, light sensitivity with pain, or a sudden drop in vision.
Treatment schedules vary based on how your eyes respond. Initially, you may need injections every four to eight weeks.
Many people start with a series of monthly loading doses, then move to a treat-and-extend plan. If the retina stays dry on OCT, we lengthen visits in 2 to 4 week steps up to 12 to 16 weeks depending on the medication. If fluid returns, we shorten the interval.
After the fluid is controlled, we may be able to extend the interval between injections or switch to a monitoring schedule. Some people need ongoing treatment for months or years, while others achieve long periods of stability. Newer options like faricimab and aflibercept 8 mg can support longer intervals for eligible patients. We tailor the plan to your individual response.
Laser treatments and photodynamic therapy were more common before anti-VEGF injections became available. Today, these approaches may be considered in specific cases where injections are not effective or appropriate.
Photodynamic therapy uses a light-activated drug to close abnormal blood vessels. Traditional laser treatment seals leaking vessels with heat. Both methods are used much less frequently now because injections usually offer better vision outcomes. Photodynamic therapy can still be helpful for selected cases such as polypoidal choroidal vasculopathy or when injections have limited effect.
Researchers continue to develop new therapies for both dry and wet AMD. Longer-lasting anti-VEGF medications and implantable drug delivery devices are now available to reduce the frequency of injections. Examples include faricimab and high-dose aflibercept for extended dosing, and an implantable ranibizumab delivery system in select patients.
For dry AMD, treatments targeting inflammation and cell death are in clinical trials. Gene therapies and stem cell approaches are also being studied. Your eligibility depends on disease stage, imaging findings, and your ability to return for visits. Ask us if any emerging treatments or trials might be suitable for your situation.
Managing AMD and Protecting Your Remaining Vision
We encourage everyone with AMD to check their vision every day at home. Use your Amsler grid or simply cover one eye and look at something with straight lines, like a doorframe or window.
Repeat with the other eye. If you notice any new distortion, blurring, or dark areas, contact our office the same day or the next morning. Early detection of changes means we can start treatment sooner.
If you have early or intermediate dry AMD, we typically recommend eye exams every six to twelve months. The exact schedule depends on the severity of your condition and whether you have other eye health concerns.
- Regular exams let us track any progression
- We update your imaging to compare changes over time
- Appointments are a chance to discuss new symptoms or concerns
- Consistent monitoring helps catch conversion to wet AMD early
Active wet AMD requires closer follow-up. You will likely visit our office every four to twelve weeks, depending on your treatment plan and how stable your condition is.
At each visit, we check your vision, perform OCT imaging, and decide whether you need another injection. Keeping these appointments is crucial for preserving your sight.
Managing your overall health reduces AMD risk and may slow progression. Work with your primary care doctor to address these factors.
- Keep blood pressure, cholesterol, and blood sugar under control
- Exercise regularly and maintain a healthy weight
- Do not smoke. If you do, ask for help to quit
- Use a wide-brimmed hat and UV-blocking sunglasses outdoors
- Review your medications and supplements with us before starting new ones
If AMD has reduced your vision, low vision aids can help you stay independent. Handheld magnifiers, electronic magnification systems, and special lighting make reading and close work easier.
Large-print books, talking watches, and high-contrast items for daily tasks improve quality of life. We can refer you to a low vision specialist who will assess your needs and recommend specific devices.
Eating a diet rich in dark leafy greens, colorful vegetables, and fish supports retinal health. Foods high in lutein, zeaxanthin, and omega-3 fatty acids are especially beneficial.
- Spinach, kale, and collard greens provide lutein and zeaxanthin
- Salmon, tuna, and sardines deliver omega-3 fats
- Reduce consumption of processed foods and saturated fats
- Wear sunglasses with UV protection when outdoors
- Stop smoking if you currently use tobacco
- Omega-3 supplements have not shown clear benefit for slowing AMD progression. Prefer fish in your diet
Frequently Asked Questions
Wet AMD generally causes more rapid and severe vision loss than dry AMD, but we have effective treatments that can slow or stop wet AMD if started promptly. Dry AMD progresses more slowly, yet advanced dry AMD can also lead to significant vision impairment over time. Both types are serious and require regular monitoring.
We cannot cure wet AMD, but anti-VEGF injections can often stabilize the disease and sometimes improve vision. The goal of treatment is to control abnormal blood vessel growth and prevent further damage. Some people regain reading vision or see better after their fluid resolves, though results vary from person to person.
Geographic atrophy is the advanced form of dry AMD. It causes well defined areas of retinal cell loss that expand over time, creating central blind spots. Injections that block part of the complement system can slow its growth but do not restore lost vision.
AMD affects central vision but typically spares peripheral (side) vision, so total blindness is rare. Many people maintain enough vision to move around safely and perform daily activities, especially with low vision aids. Early detection and treatment, particularly for wet AMD, greatly improve the chances of preserving useful vision.
AMD often starts in one eye and may later develop in the other, though the timing and severity can differ. Some people only experience significant problems in one eye. We monitor both eyes closely because risk factors and changes in one eye can signal increased risk for the fellow eye.
There is no guaranteed way to prevent dry AMD from becoming wet AMD, but taking AREDS2 vitamins if recommended, eating a healthy diet, not smoking, and protecting your eyes from UV light may reduce your risk. Daily home monitoring with an Amsler grid and keeping regular appointments help us detect any conversion quickly so treatment can begin immediately.
No. Blue-light blocking lenses and most over-the-counter eye drops do not cure or prevent AMD. A balanced diet rich in leafy greens and fish supports eye health, and AREDS2 supplements can help if you meet criteria.
