Dry (Nonexudative) AMD
What Is Dry AMD and How Does It Progress
The macula is a small area at the center of your retina responsible for sharp, central vision. In dry AMD, the cells in your macula begin to thin and break down. Waste products accumulate beneath the retina, forming yellow deposits called drusen.
Over time, these changes can cause the macula to lose its ability to function properly. You may notice that reading, driving, or recognizing faces becomes harder. Dry AMD rarely causes total vision loss because your peripheral vision usually remains intact.
Dry AMD accounts for about 80 to 90 percent of all AMD cases and progresses slowly over many years. Wet AMD, on the other hand, develops when abnormal blood vessels grow beneath the retina and leak fluid or blood. Wet AMD can cause rapid and severe vision loss.
- Dry AMD involves gradual thinning and breakdown of macular tissue
- Wet AMD involves abnormal blood vessel growth and leakage
- Most people with wet AMD had prior dry AMD, although wet AMD can sometimes be diagnosed without a known history of dry changes
- Wet AMD requires urgent treatment to prevent permanent damage
We classify dry AMD into three stages based on the size and number of drusen and the extent of retinal changes. In early dry AMD, you have small or medium drusen but usually no vision symptoms. Intermediate dry AMD involves larger drusen or pigment changes, and you may begin to notice mild vision problems.
Advanced dry AMD, also called geographic atrophy, occurs when significant areas of the macula have deteriorated. It is important to note that the term advanced AMD can refer to either geographic atrophy (advanced dry AMD) or neovascular AMD (wet AMD), and imaging helps us distinguish between the two. At the advanced dry stage, you will likely experience noticeable central vision loss that affects daily activities. Regular monitoring helps us track your progression and intervene when necessary.
- Early dry AMD: small to medium drusen, usually no symptoms
- Intermediate dry AMD: larger drusen or pigment changes, mild vision problems may begin
- Advanced dry AMD (geographic atrophy): significant macular tissue loss, noticeable central vision impairment
Drusen are tiny yellow or white deposits that form under the retina. We often find them during routine eye exams, even before you notice any symptoms. Small drusen are common as you age and do not always lead to AMD.
Larger or more numerous drusen, however, indicate a higher risk of progression. We use special imaging to measure and monitor your drusen over time. Tracking these changes helps us determine how quickly your dry AMD is advancing and whether you might benefit from vitamin supplements or other interventions.
Recognizing the Symptoms and Warning Signs
Dry AMD often begins without obvious symptoms, especially in the early stage. You might notice very subtle changes such as needing slightly more light to read or taking a bit longer to adjust when moving from bright to dim lighting. Because these changes are gradual, many people do not realize anything is wrong until the condition has progressed.
That is why regular comprehensive eye exams are so important, particularly after age 50. We can detect drusen and early macular changes long before you notice any vision problems, giving you the best chance to slow progression.
As dry AMD advances, you may begin to notice that straight lines appear wavy or distorted. This symptom, called metamorphopsia, happens when the macula becomes uneven due to drusen or tissue breakdown. However, new or suddenly worse distortion is especially concerning for conversion to wet AMD and warrants prompt evaluation, even if you have already been diagnosed with dry AMD. You might also find that colors seem less vibrant or that a blurry spot appears in the center of your vision.
- Straight edges like door frames or window blinds may look bent
- Text on a page might appear curved or jumbled
- A dim or blank area can develop in your central field of view
- New or suddenly worse distortion is not typical of stable dry AMD and should be checked urgently
Because dry AMD affects your central vision, tasks that require seeing fine details become difficult. You may struggle to read small print, even with your regular glasses. Recognizing familiar faces across a room or seeing expressions clearly can also become challenging.
Many people with intermediate or advanced dry AMD find that words seem to disappear in the middle of a sentence or that letters blend together. If you notice these symptoms, it is time to schedule an eye exam so we can evaluate your macula and discuss strategies to help you maintain your independence.
One of the earliest signs of dry AMD is needing brighter light to read, sew, cook, or do other close-up work. Your eyes may take longer to adjust when you move from a bright environment to a darker one. These changes often happen so slowly that you might not connect them to an eye problem.
While needing extra light is common with normal aging, a sudden or significant increase in your lighting needs can indicate macular changes. We recommend paying attention to these shifts and mentioning them at your next eye exam.
If you experience a sudden change in your vision, such as a rapid increase in blurriness, a new dark spot in your central vision, or a sudden onset of distorted lines, contact our eye doctor right away. These symptoms can signal conversion from dry AMD to wet AMD, which requires urgent treatment.
- Sudden blurring or distortion in one or both eyes
- A new or expanding blind spot in your central vision
- Rapid worsening of your ability to read or see faces
- Any abrupt change in vision quality or color perception
Who Is at Risk for Dry AMD
Age is the single biggest risk factor for dry AMD. The condition is rare before age 50, but your risk increases significantly with each passing decade. By age 75, a substantial number of people have some form of AMD, and the risk continues to climb into your 80s and beyond.
While we cannot stop the aging process, knowing your risk can motivate you to adopt healthy habits and schedule regular eye exams. Early detection gives you the best opportunity to slow progression and preserve your vision for as long as possible.
If your parents or siblings have AMD, your risk is higher than average. Researchers have identified several genes that influence your likelihood of developing the condition. Having one or more of these genetic variants does not guarantee you will get AMD, but it does increase your susceptibility.
We encourage you to share your family history during your eye exam. Knowing that AMD runs in your family helps us tailor your monitoring schedule and discuss preventive strategies. We will recommend more frequent screenings if you have a strong family history. Genetic testing for AMD is not routinely recommended because it usually does not change our treatment approach, but we may discuss it in select circumstances such as research participation or unusually early onset of disease.
Smoking is the strongest modifiable risk factor for dry AMD. Studies show that current smokers are two to three times more likely to develop AMD than people who have never smoked. Smoking reduces blood flow to the retina, increases oxidative stress, and accelerates the breakdown of macular tissue.
- Tobacco smoke introduces harmful chemicals that damage retinal cells
- Smoking lowers antioxidant levels that normally protect your macula
- Even secondhand smoke exposure can increase your risk
- Quitting at any age can reduce your risk and slow progression if you already have early AMD
Your eyes rely on a healthy circulatory system to deliver oxygen and nutrients to the retina. Conditions like high blood pressure, high cholesterol, and heart disease can affect the tiny blood vessels in your eyes. Poor circulation and chronic inflammation may be associated with an increased risk of macular changes, although the exact relationships are still being studied.
Managing your cardiovascular health through regular checkups, medication if needed, and lifestyle changes can benefit both your heart and your eyes. We often work with your primary care doctor to ensure your overall health supports your vision.
What you eat can influence your risk of developing or worsening dry AMD. Diets low in fruits, vegetables, and omega-3 fatty acids may increase your risk, while diets rich in antioxidants and healthy fats appear protective. Obesity, especially abdominal fat, also raises your risk of progression.
Nutritional deficiencies in key vitamins and minerals may leave your retina more vulnerable to oxidative damage. We may recommend dietary changes or specific supplements based on your stage of AMD and overall nutritional status.
In addition to age, family history, smoking, and cardiovascular health, several other factors may influence your risk of developing dry AMD. While not all of these factors are modifiable, being aware of them can help you and your eye doctor assess your overall risk profile and tailor your screening and prevention plan.
- Race and ethnicity: dry AMD is more common in people of European ancestry compared to other groups
- Light iris color: people with blue or light-colored eyes may have a slightly higher risk
- Cumulative lifetime sun exposure: the evidence is mixed, but many experts recommend UV protection as a reasonable precaution
- Dietary patterns: diets low in antioxidants and omega-3 fatty acids may increase susceptibility
- Refractive status: some studies suggest that farsightedness (hyperopia) may be associated with higher AMD risk
How We Diagnose Dry AMD
Diagnosing dry AMD begins with a thorough eye exam that includes checking your visual acuity, measuring your eye pressure, and reviewing your medical and family history. We will ask about any vision changes you have noticed, even if they seem minor. This conversation helps us understand how your eyes are functioning in daily life.
After the initial assessment, we will dilate your pupils with special eye drops. Dilation allows us to examine the back of your eye, including the macula, in detail. The process is painless, although you may experience blurry vision and light sensitivity for a few hours afterward.
During a dilated exam, we use a bright light and magnifying lenses to look directly at your retina and macula. We can see drusen, pigment changes, and areas of atrophy that indicate dry AMD. This hands-on examination remains one of the most important tools for detecting and monitoring the condition.
- We examine the size, number, and location of drusen
- We look for pigment clumping or loss in the macula
- We check for any signs of geographic atrophy or wet AMD
- We compare findings to previous exams to track changes over time
The Amsler grid is a simple tool that looks like graph paper with a dot in the center. When you focus on the dot, the lines should appear straight and evenly spaced. If the lines look wavy, broken, or missing, it may indicate macular changes.
We use the grid in the office to check for distortions, and we may give you one to use at home. Regular self-testing can help you catch sudden changes early, especially if you are at risk for conversion to wet AMD. If you notice any new distortions, contact us right away.
Optical coherence tomography, or OCT, is a non-invasive imaging test that creates detailed cross-sectional images of your retina. It works much like an ultrasound but uses light waves instead of sound. OCT allows us to see the individual layers of your retina and measure their thickness with precision.
This technology is especially helpful for detecting early thinning of the macula, identifying fluid that might signal wet AMD, and monitoring geographic atrophy. We can compare OCT scans over time to see exactly how your macula is changing, which helps guide your treatment and follow-up schedule.
Fundus photography involves taking high-resolution color images of the back of your eye. These photographs provide a permanent record of the appearance of your retina, including the size, shape, and location of drusen. We can use these images to monitor changes from one visit to the next.
In some cases, we may use specialized imaging techniques such as fundus autofluorescence, which highlights areas of retinal stress or damage. These advanced imaging tools help us detect subtle changes that might not be visible during a standard exam.
Treatment and Management Options
If you have advanced dry AMD with geographic atrophy, we may recommend FDA-approved intravitreal injection therapies that can slow the growth of GA lesions. These medications do not restore vision you have already lost, but they may help preserve remaining central vision by slowing the rate at which the atrophy expands. Treatment involves ongoing injections into the eye, typically given monthly or every other month depending on the specific medication and your individual treatment plan.
Because these therapies require continued monitoring and regular visits, we will work closely with you to ensure the treatment schedule fits your needs and goals. Not everyone with dry AMD is a candidate. These medications are approved specifically for geographic atrophy confirmed on clinical examination and imaging, not for early or intermediate dry AMD.
- Goal is to slow GA lesion growth, not to improve vision or reverse damage
- Dosing frequency is typically monthly or every other month, individualized to your case
- Ongoing OCT scans and dilated exams are required to monitor response and safety
- Main risks include eye infection (endophthalmitis), intraocular inflammation, rare retinal vasculitis, and temporary eye pressure elevation
- There is an increased risk of developing wet AMD during treatment, so prompt evaluation of any new distortion or blind spot is essential
- Consistent follow-up and adherence to the recommended schedule are critical for safety and benefit
Intravitreal injections are generally safe, but any procedure that involves entering the eye carries some risk. The most serious risk is endophthalmitis, a rare but vision-threatening infection inside the eye. Other potential complications include increased eye pressure, inflammation, bleeding, and floaters. We take every precaution to minimize these risks, including sterile technique and careful post-injection monitoring.
After each injection, contact our office the same day or seek urgent eye care if you notice any of the following warning signs:
- Worsening eye pain or pressure that does not improve with over-the-counter pain relief
- Marked redness, swelling, or discharge from the eye
- Sudden decrease in vision or a new curtain or shadow in your field of view
- Increasing sensitivity to light or a sudden shower of new floaters
- Any symptom that feels different from the mild irritation or scratchiness we discussed as normal
The Age-Related Eye Disease Study 2, or AREDS2, found that a specific combination of vitamins and minerals can reduce the risk of progression to advanced AMD in people with intermediate dry AMD or advanced AMD in one eye. The formula includes vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin.
- We may recommend AREDS2 supplements if you have intermediate dry AMD
- The formula can slow progression to advanced stages
- Supplements do not help if you have only early dry AMD or no AMD at all
- You should use a formula that matches the AREDS2 research doses
Before starting AREDS2 supplements, confirm that the product label matches the AREDS2 formulation, which does not contain beta-carotene. You should also review your medications and medical history with us or your primary care doctor to ensure the supplements are safe for you.
If you have only early dry AMD with small drusen and no other risk factors, AREDS2 vitamins have not been shown to provide benefit. Similarly, if you have no signs of AMD, taking these high-dose supplements is not necessary and may not be safe. Some ingredients, particularly zinc in high doses, can cause side effects or interact with medications.
We evaluate your individual stage of AMD, your overall health, and any medications you take before recommending supplements. If you already eat a diet rich in the nutrients found in AREDS2 formulas, we will discuss whether supplementation is right for you.
- Confirm the label says AREDS2 and does not include beta-carotene, which current and former smokers should avoid
- Discuss with your primary care doctor if you take blood thinners or antiplatelet medications, or if you have a bleeding disorder, because vitamin E may increase bleeding risk
- Zinc can cause stomach upset, nausea, or other gastrointestinal side effects; copper is included to prevent zinc-induced copper deficiency
- Avoid taking additional multivitamins that contain the same ingredients, as excessive doses may be harmful
- If you are pregnant, breastfeeding, or have significant kidney or liver disease, discuss with us before starting any high-dose supplement
Although dry AMD is more common, it can convert to wet AMD in some cases. Wet AMD develops when abnormal blood vessels grow beneath the retina and leak fluid, causing rapid vision loss. Catching this conversion early is critical because prompt treatment with injections can often stop the damage.
We will teach you how to monitor your vision at home using an Amsler grid and instruct you to contact us immediately if you notice sudden changes. Regular follow-up exams allow us to detect early signs of fluid or new blood vessel growth before they cause significant harm.
Several investigational treatments for dry AMD are in various stages of research. These include medications designed to slow geographic atrophy, gene therapies to address inherited risk factors, and stem cell approaches to replace damaged retinal cells. Participating in a clinical trial may give you access to cutting-edge therapies that are not yet available to the general public.
If you are interested in clinical trials, we can discuss whether you might be a candidate and provide information about studies currently enrolling patients. Keep in mind that trial participation involves regular monitoring and may include treatments that are still being tested for safety and effectiveness.
Daily Strategies and Self-Care
A diet high in dark leafy greens like spinach, kale, and collard greens provides lutein and zeaxanthin, antioxidants that concentrate in the macula and help protect it from damage. Fatty fish such as salmon, mackerel, and sardines are rich in omega-3 fatty acids, which support retinal health and reduce inflammation.
- Aim for at least two servings of leafy greens per day
- Include fish in your diet two or three times per week
- Add colorful fruits and vegetables for a variety of antioxidants
- Limit processed foods, saturated fats, and refined sugars
If you smoke, quitting is the single most important step you can take to slow the progression of dry AMD. When you quit, your overall circulation and health begin to improve. Over time, your risk of further macular damage decreases, although it may take years to return to the level of someone who never smoked.
We understand that quitting smoking is challenging, and we are here to support you. Your primary care doctor can offer resources such as counseling, nicotine replacement, or prescription medications to help you succeed. The benefits for your eyes, heart, and overall health make every effort worthwhile.
The link between ultraviolet light from the sun and macular damage is not fully established, and evidence is mixed. However, wearing sunglasses that block 100 percent of UVA and UVB rays is a reasonable precaution for overall ocular health, especially during peak sunlight hours. A wide-brimmed hat adds extra protection by shading your eyes from above.
Look for sunglasses labeled with UV400 or 100 percent UV protection. Polarized lenses can reduce glare, making it easier to see in bright conditions, but polarization alone does not guarantee UV protection. We can recommend specific eyewear if you need prescription sunglasses or have other eye conditions.
As your central vision declines, simple adjustments to your environment can make daily tasks easier. Magnifying glasses, handheld magnifiers, or electronic devices that enlarge text can help you read books, labels, and bills. Task lighting, such as a bright lamp positioned directly over your work area, reduces eye strain and improves contrast.
Many people find that using a combination of magnification and lighting gives the best results. We can refer you to a low vision specialist who can recommend specific devices and teach you techniques to make the most of your remaining vision.
We will provide you with an Amsler grid and instructions on how to use it at home. We recommend testing each eye separately, ideally daily if you are at higher risk for progression, or at least several times a week otherwise. Cover one eye, focus on the center dot, and check whether the lines appear straight and complete. If you notice new distortions, blank spots, or wavy lines, call our office immediately.
Consistent self-monitoring can help you detect conversion to wet AMD at the earliest possible stage. Early treatment of wet AMD can preserve vision that might otherwise be lost, so do not hesitate to reach out if you see any changes.
The frequency of your follow-up exams depends on the stage of your dry AMD and other risk factors. If you have early dry AMD, we may recommend exams every 12 months. For intermediate dry AMD, we typically suggest visits every 6 to 12 months. If you have advanced dry AMD or are at high risk for conversion to wet AMD, we may want to see you every 3 to 6 months.
Staying on schedule with your exams allows us to track changes in your macula, adjust your treatment plan, and catch any complications early. If you notice vision changes between scheduled visits, contact us right away rather than waiting for your next appointment.
Frequently Asked Questions
Dry AMD very rarely causes complete blindness. The condition primarily affects your central vision, which you use for tasks like reading and recognizing faces, but it usually spares your peripheral vision. This means that even in advanced stages, you will likely retain enough side vision to navigate your environment and maintain a degree of independence.
No, most people with dry AMD will not develop wet AMD. However, a small percentage do experience conversion, especially those with larger drusen or more advanced dry AMD. Regular monitoring and self-testing at home help ensure that if conversion does occur, we can treat it promptly to minimize vision loss.
Yes, as of 2025, there are FDA-approved intravitreal injection therapies specifically for geographic atrophy, the advanced form of dry AMD. These medications can slow the growth of GA lesions but do not restore vision that has already been lost. Treatment requires ongoing injections and regular monitoring visits. Risks include eye infection, inflammation, and an increased chance of developing wet AMD, so close follow-up is essential. We will discuss whether you are a candidate based on the extent of your GA and your overall health and treatment goals.
Currently, there are no eye drops proven to treat or slow dry AMD. Some drops may be in development or early research, but none have received FDA approval for this purpose as of 2025. If new therapies become available, we will discuss them with you during your follow-up visits.
Whether you can drive safely depends on the severity of your central vision loss and the legal vision requirements in your state. Many people with early or intermediate dry AMD continue to drive without problems. As the condition progresses, however, reduced central vision and contrast sensitivity can make driving unsafe, especially at night or in unfamiliar areas. We can assess your vision and help you decide when it may be time to limit or stop driving.
Routine screening for AMD is not necessary in children or young adults unless there is a strong family history of early-onset disease or a known genetic syndrome. Most AMD develops after age 50. That said, if AMD runs in your family, your adult children should have regular comprehensive eye exams starting in their 40s or 50s and adopt healthy lifestyle habits to reduce their risk.
