Dry age-related macular degeneration is a gradual eye condition that can blur your ability to see the world clearly in front of you, though it never takes away all of your vision. Understanding what happens inside your eye, how the condition develops, and what steps you can take may help you protect your remaining sight for years to come.
Understanding Dry Age-Related Macular Degeneration
Dry age-related macular degeneration, often called dry AMD, is an eye disease that develops when a tiny part at the back of your eye begins to break down. This part is called the macula, which sits inside the retina—the light-sensitive layer lining the back of your eye. The macula is responsible for your sharp, straight-ahead vision, helping you read, recognize faces, drive, and see fine details directly in front of you.[1][3]
The term “dry” does not mean your eyes feel dry or uncomfortable. It simply describes the type of macular degeneration you have, distinguishing it from the “wet” form. Dry AMD happens when the cells of the macula slowly deteriorate over many years. As these cells die off, they are not replaced or renewed, leading to a slow decline in central vision.[2]
Dry AMD is the most common form of macular degeneration. Nearly 90 percent of people diagnosed with age-related macular degeneration have the dry type. While it can be distressing to lose some of your central vision, people with dry AMD do not become completely blind. Their side vision, called peripheral vision, remains intact, allowing them to move around and maintain much of their independence.[5]
How Common Is This Condition?
Age-related macular degeneration affects millions of people worldwide. In the United States alone, almost 20 million adults have this condition, and the number is expected to grow. Globally, predictions suggest that by 2040, as many as 288 million people may be living with macular degeneration.[5]
In the United States, macular degeneration stands as a leading cause of vision loss for those aged 60 and older. The condition is especially common among people over 50, with the risk increasing as you age. People aged 55 and older are significantly more likely to develop AMD compared to younger adults.[3][5]
What Causes Dry AMD?
The exact reasons why dry AMD develops are not fully understood, but aging is the primary factor. As you get older, changes occur naturally in the back of your eye. In dry AMD, small yellowish deposits called drusen begin to form beneath the macula. Drusen are made up of proteins and fats. When these deposits accumulate, they interfere with the macula’s ability to receive nutrients. Over time, the macula becomes thinner and drier, and its cells start to waste away.[5][6]
While aging is the strongest risk factor, macular degeneration can also run in families. Some people inherit a tendency to develop the condition. However, many individuals with no family history still develop dry AMD as they grow older.[5]
Who Is at Risk?
Certain factors can increase your chances of developing dry AMD. Age is the most powerful risk factor. The older you are, the higher your risk. Beyond age, several other factors can raise your likelihood of developing this condition.[3]
Having a family history of macular degeneration puts you at greater risk. If your parents or siblings had AMD, you are more likely to develop it yourself. Race also plays a role—people who are Caucasian face a higher risk compared to other racial groups.[3][6]
Smoking is a major modifiable risk factor. Cigarette smoking significantly increases the risk of developing macular degeneration and can accelerate its progression. If you smoke, quitting can slow the disease and reduce further damage to your vision.[6][16]
Other risk factors include being overweight, having high blood pressure, and eating a diet high in saturated fats. High cholesterol and cardiovascular disease may also contribute to a higher risk. Women may face a slightly higher risk than men, and some studies suggest that lower education levels and higher body mass index could play a role as well.[5][6]
Recognizing the Symptoms
Dry AMD develops in three stages: early, intermediate, and late. Symptoms depend on which stage the condition has reached. In the early stage, there are usually no symptoms at all. Your vision appears normal, and you may not realize anything is happening inside your eye. Only an eye care professional examining the back of your eye can detect early signs, such as small drusen deposits.[3][6]
As dry AMD progresses to the intermediate stage, some people still notice nothing wrong. Others may begin to experience mild blurriness in their central vision or have trouble seeing in dim lighting. You might need more light when reading or find it difficult to adjust when moving from bright areas to darker ones.[3][6]
In the late or advanced stage, symptoms become more noticeable. Many people observe that straight lines, such as door frames or lampposts, start to appear wavy, bent, or distorted. You may see a blurry spot near the center of your vision that gradually grows larger over time. Some people describe seeing gaps or dark spots, almost like a smudge on glasses that will not wipe away. Colors may seem less bright, and you may continue to struggle in low lighting conditions.[1][2][3]
Words may disappear while you are reading, and recognizing familiar faces can become challenging. These changes usually happen slowly over the course of months or years, though the speed can vary from person to person.[1][2]
How Dry AMD Is Different from Wet AMD
Dry AMD and wet AMD are two types of the same disease, but they behave differently. Dry AMD is far more common and progresses gradually. Wet AMD, on the other hand, is less common but more severe. Wet AMD develops when abnormal blood vessels grow beneath the retina and leak blood and fluid, damaging the macula rapidly.[3][7]
Around 10 to 15 percent of people with dry AMD eventually develop wet AMD. If you have dry AMD and notice a sudden change in your vision—such as a rapid increase in distortion or blurriness—it is essential to contact your eye doctor or specialist urgently. This could signal that dry AMD has turned into wet AMD, which requires prompt treatment to prevent further vision loss.[2][10]
Prevention and Reducing Your Risk
While there is no guaranteed way to prevent dry AMD, there are steps you can take to reduce your risk and slow its progression. Lifestyle choices play an important role in protecting your eye health.[16]
Eating a healthy diet rich in certain nutrients may help. Foods high in leafy green vegetables, colorful fruits, fish, and nuts support eye health. Nutrients such as lutein and zeaxanthin—found in green leafy vegetables—along with omega-3 fatty acids from fish, are particularly beneficial. Vitamins C and E, as well as zinc and copper, may also play a protective role.[16][20]
Your doctor may recommend specific dietary supplements, especially if you already have intermediate dry AMD. A well-known formula called AREDS2 contains vitamins C and E, zinc, copper, lutein, and zeaxanthin. Studies have shown this supplement can slow the progression of dry AMD in some people.[7][16]
Regular physical activity can improve your overall health and may help slow the progression of AMD. Maintaining a healthy weight, controlling blood pressure, and managing cholesterol levels are all important steps.[16][20]
Quitting smoking is one of the most effective actions you can take. Smoking is strongly linked to a higher risk and faster progression of AMD. By stopping smoking, you give your eyes a better chance of staying healthier for longer.[16][20]
Protecting your eyes from sunlight is another simple but effective step. Wearing sunglasses that block ultraviolet (UV) rays when you are outdoors can help shield your eyes from damage.[20]
What Happens Inside Your Eye: Pathophysiology
Understanding what changes occur inside your eye during dry AMD can help you grasp why your vision is affected. The macula, which controls your sharp central vision, relies on healthy cells and a steady supply of nutrients. In dry AMD, the buildup of drusen under the macula disrupts this delicate system.[6]
Drusen are pale yellow deposits composed of proteins and fats. In the early stages, these deposits are small and usually harmless. As they accumulate and grow larger, they interfere with the macula’s ability to function properly. The macula starts to thin, and light-sensitive cells within it begin to die off. This gradual loss of cells leads to the blurring and distortion of central vision.[5][6]
In the advanced stage of dry AMD, known as geographic atrophy, larger areas of the macula waste away, creating well-defined zones of cell loss. When these areas reach the very center of the macula—called the fovea—central vision becomes more severely affected. The atrophic areas often start near the center and progressively expand into it, causing increasing vision loss over time.[6]
Some people with dry AMD also develop a pattern of whitish-yellow dots that look like a net under the retina. These are called reticular drusen or subretinal drusenoid deposits. Individuals with these deposits may experience additional difficulty seeing in dimly lit settings and may need longer to adjust from bright light to darkness.[6]
The underlying cause of these changes remains unclear, but aging and genetic factors likely contribute. The breakdown of normal metabolic processes in the retina and the accumulation of waste products lead to cell death and tissue damage in the macula.[5]
Getting a Diagnosis
Diagnosing dry AMD involves a comprehensive eye examination. An eye care professional, such as an optometrist or ophthalmologist, will review your medical and family history and perform a complete eye exam. They will look for signs of macular degeneration by examining the back of your eye.[9][19]
To get a clear view of the retina, your eye doctor will put drops in your eyes to dilate them. This allows the doctor to see the macula and check for the presence of drusen. People with macular degeneration often have many drusen deposits, which appear as a mottled pattern in the retina.[9][19]
Your doctor may use a test called the Amsler grid, a simple grid of straight lines, to check for changes in your central vision. If you have macular degeneration, some of the lines may look wavy, broken, or distorted, and you might see blank spots near the center of the grid.[9][19]
Advanced imaging techniques can provide detailed pictures of your retina. Optical coherence tomography (OCT) is a non-invasive test that creates cross-sectional images of the retina, allowing your doctor to see the layers and detect thinning or atrophy in the macula. Some optometrists and eye clinics use OCT scans to detect early signs of macular degeneration. However, you may be charged for these tests.[2][10]
Other tests, such as fluorescein angiography or indocyanine green angiography, involve injecting a dye into a vein in your arm. As the dye travels through the blood vessels in your eye, a special camera takes pictures. These images help the doctor see any changes in the retina or blood vessels, though these tests are more commonly used to evaluate wet AMD.[9][19]
Because early dry AMD has no symptoms, regular eye exams are essential. Your eye doctor can detect the disease before you notice any vision changes, giving you the best chance to take preventive steps and monitor the condition over time.[3]
Treatment Options
Currently, there is no medical treatment that can cure dry AMD or restore vision that has already been lost. However, there are steps you can take to manage the condition and slow its progression, especially if caught early.[2][10][14]
For people with intermediate dry AMD, dietary supplements have shown promise in slowing the disease. The AREDS2 formula, which includes vitamins C and E, zinc, copper, lutein, and zeaxanthin, may reduce the risk of progression to advanced AMD. Your eye doctor can recommend whether these supplements are right for you.[7][16]
Recently, new treatments have been approved for advanced dry AMD, specifically for a condition called geographic atrophy. One such treatment is pegcetacoplan, sold under the brand name Syfovre™. This medication is given as an injection inside the eye and may help slow the worsening of geographic atrophy. While it does not cure the condition or restore lost vision, it offers hope for preserving remaining sight for a longer period.[12]
Another approved treatment for geographic atrophy is available, and research into new therapies continues. Gene therapies and stem cell treatments are being explored as potential future options. Clinical trials are underway, and your specialist can let you know if there are any studies you could participate in.[11][14]
Lifestyle changes remain an important part of managing dry AMD. Eating a diet rich in eye-healthy nutrients, exercising regularly, quitting smoking, and protecting your eyes from UV rays all contribute to slowing the progression of the disease.[16][20]
Living with Dry AMD
Receiving a diagnosis of dry AMD can be worrisome, but it does not mean you will lose all your vision. Most people with dry AMD retain good vision for their entire lives, and those who lose central vision almost always maintain their peripheral vision. With training, adaptive devices, and support, you can continue to live an independent and fulfilling life.[17]
Vision rehabilitation services can help you adjust and function better with your remaining vision. A low-vision therapist can recommend personalized strategies and tools to assist with daily activities. Magnifiers, large-print books, electronic reading devices, and talking equipment such as clocks, scales, and timers can make everyday tasks easier.[17][18]
Using brighter lighting in your home and reducing glare can improve your ability to see. Task lighting that highlights what you are working on, plain pale decor that reflects light, and adjusting your distance to the television can all help. Contrasting colors—such as using brightly colored cups or different colored chopping boards—make it easier to differentiate items.[18]
Learning to use your other senses, such as hearing and touch, can provide additional information and help you navigate daily life. Many people with low vision are surprised at how much they can learn by paying closer attention to sounds and textures.[17]
Emotional support is also important. Living with vision loss can be emotionally challenging, and it is natural to feel frustrated or sad. Counseling and support groups provide a safe space to share your experiences and learn coping strategies. Staying connected with family, friends, and community activities can improve your emotional well-being.[17]
Regular monitoring is crucial. Keep up with scheduled eye exams so your doctor can track changes in your condition and adjust your care plan as needed. If you notice any sudden changes in your vision, contact your eye care professional immediately.[2][10]
