Managing Life with Age-Related Macular Degeneration
Understanding Age-Related Macular Degeneration
AMD affects the macula, the small central area of the retina responsible for sharp, detailed vision. The macula is what you rely on to read, recognize faces, drive, and see fine details. When the macula is damaged, central vision becomes blurry or distorted, but side vision typically remains intact.
Imagine looking at a clock. With AMD, you might see the numbers around the edge but not the hands in the center. This loss of central vision can make everyday tasks more difficult.
About 8 out of 10 people with AMD have the dry form (NEI, 2023). Dry AMD develops when parts of the macula thin with age. Tiny yellow deposits called drusen build up beneath the retina. Over time, these changes can lead to pigment abnormalities or geographic atrophy, an area of cell loss in the retina. Dry AMD usually progresses slowly, and vision loss may be gradual.
Wet AMD, also called neovascular AMD, occurs when abnormal blood vessels grow beneath the retina. This process is called choroidal neovascularization. These abnormal vessels can bleed or leak fluid, distorting the structure of the retina. Without prompt treatment, the leaking vessels can form scar tissue and lead to severe loss of central vision.
Dry AMD can progress to wet AMD at any stage. Not everyone with dry AMD will develop wet AMD, but the risk increases as the disease advances. Regular monitoring by a retina specialist is essential because early detection of wet AMD leads to better treatment outcomes. Any sudden change in vision should be evaluated right away.
Who Is Affected and Risk Factors
The primary risk factor for AMD is age. The older you are, the greater your risk. Among Americans aged 65 and older, AMD prevalence is approximately 10.40% (VEHSS-Medicare, 2021). By age 75, roughly 1 in 3 people in the United States will have some form of AMD (Macular Degeneration Association, 2024).
Cigarette smoking is the primary modifiable risk factor for advanced AMD. Smoking doubles the risk of developing AMD. Recent research suggests that living in an air-polluted environment may also increase risk.
Other modifiable risk factors include:
- A diet high in saturated fats and low in antioxidants
- Uncontrolled cardiovascular disease or high blood pressure
- High cholesterol levels
- Being overweight, particularly around the abdomen
Genetics has a powerful influence on AMD risk. People with a family history of AMD are at significantly higher risk. Northern European ancestry and White ethnicity are also associated with elevated risk. While you cannot change your genes, knowing your family history helps your retina specialist plan appropriate monitoring.
Signs and Symptoms
In its early stages, AMD may produce no noticeable symptoms at all. This is one reason regular eye exams are so important. As the disease progresses, you may notice a slight decline in visual sharpness. Colors may appear less intense or less bright than they once did.
As AMD progresses, symptoms become more noticeable. You may see blurry or dark areas in the center of your vision. Straight lines, such as door frames or text, may appear bent or wavy. In a recent survey, more than 2 in 5 adults over 40 in the United States did not know that loss of central vision could be a symptom of AMD (ASRS, 2024).
Do not wait if you notice a sudden change in your vision. Sudden dark spots, new blurriness, or straight lines that appear bent or wavy can signal the onset of wet AMD. See a retina specialist or go to the emergency room immediately if you experience any of these sudden changes. Early treatment of wet AMD provides the best chance of preserving vision.
Diagnosis and Testing
A retina specialist can detect AMD during a comprehensive dilated eye exam. During this exam, drops are placed in the eyes to widen the pupils. This allows the specialist to examine the retina and macula for drusen, pigment changes, or signs of abnormal blood vessel growth. This exam is the foundation of AMD detection.
Optical coherence tomography, or OCT, is an imaging test that creates detailed cross-sectional pictures of the retina. OCT can reveal fluid beneath or within the retina, thinning of the macula, and areas of geographic atrophy. Retina specialists use OCT at nearly every visit to track changes over time and guide treatment decisions.
Fluorescein angiography involves injecting a special dye into a vein in the arm. As the dye travels through the retinal blood vessels, a camera captures images showing leakage or abnormal vessel growth. This test is particularly useful for confirming a diagnosis of wet AMD and planning treatment.
An Amsler grid is a simple chart with a pattern of straight lines and a central dot. Your retina specialist may ask you to use this grid at home to monitor your vision between appointments. If lines on the grid look wavy, broken, or missing, this may indicate a change that requires prompt evaluation.
Treatment Options for Wet AMD
Intravitreal injection therapy using anti-VEGF agents (medications that block vascular endothelial growth factor) is the standard treatment for wet AMD. These medications are injected directly into the eye to block the signals that cause abnormal blood vessel growth and leakage. Anti-VEGF treatment stabilizes or improves vision in most patients when started early.
Commonly used anti-VEGF medications include:
- Eylea (aflibercept), typically given every 4 to 8 weeks after loading doses
- Eylea HD (high-dose aflibercept), which may extend to every 8 to 16 weeks
- Lucentis (ranibizumab), typically given every 4 weeks
- Vabysmo (faricimab), a bispecific antibody targeting both VEGF and angiopoietin-2, given every 4 to 16 weeks
- Avastin (bevacizumab), FDA-approved for cancer and used off-label for eye conditions, given every 4 to 6 weeks
Laser photocoagulation (thermal laser applied to the retina) and photodynamic therapy (a light-activated drug treatment) were once standard treatments for certain forms of wet AMD. Anti-VEGF injections have largely replaced these approaches. They may still be used in specific cases as determined by a retina specialist.
Treatment Options for Dry AMD
Geographic atrophy, the advanced form of dry AMD, now has two FDA-approved treatments. These are different from the anti-VEGF injections used for wet AMD. Syfovre (pegcetacoplan), a complement C3 inhibitor, is given as an injection into the eye monthly or every other month. It reduced the growth rate of geographic atrophy by 20% to 29% in clinical trials (FDA, 2023).
Izervay (avacincaptad pegol), a complement C5 inhibitor, reduced geographic atrophy growth by about 27% in studies (FDA, 2023). These treatments slow the progression of geographic atrophy but have not been shown to improve vision that has been lost. These complement inhibitor treatments are specifically for geographic atrophy associated with dry AMD and are different from wet AMD treatments.
The Age-Related Eye Disease Study 2 (AREDS2) found that a specific combination of antioxidant vitamins and minerals can reduce the risk of intermediate AMD progressing to advanced AMD (NEI, 2013). A retina specialist may recommend AREDS2 supplements for patients with intermediate AMD or advanced AMD in one eye.
AREDS2 supplements have not been shown to benefit patients with less than intermediate AMD. There is also no evidence of preventive value for family members without signs of AMD. Talk with your retina specialist before starting any supplement.
What to Expect
If you are diagnosed with wet AMD, treatment typically begins with a series of monthly anti-VEGF injections called loading doses. Before each injection, the eye is numbed with anesthetic drops and cleaned with an antiseptic solution. The injection itself takes only a few seconds. You may feel brief pressure or mild discomfort. Most people return to normal activities within a day.
After the loading phase, your retina specialist will monitor your response with OCT imaging. Your specialist will determine the best interval between injections. Some patients may extend the time between treatments, while others need more frequent injections.
If you have dry AMD, your retina specialist will schedule regular follow-up visits to monitor for progression. These visits usually include OCT imaging and a visual acuity check. Between appointments, home monitoring with an Amsler grid helps you watch for sudden changes. If geographic atrophy is present, your specialist may discuss complement inhibitor treatment to slow progression.
Treatment for AMD aims to preserve existing vision and slow further loss. In many cases of wet AMD, anti-VEGF injections can stabilize vision and may improve it. Results vary from person to person, and vision lost to scarring or advanced atrophy may not return. Consistent follow-up and timely treatment provide the best opportunity for maintaining functional vision.
Living with AMD
A Mediterranean diet rich in fruits, vegetables, whole grains, fish, and healthy fats like olive oil is associated with a reduced risk of AMD progression (NEI, 2023). Leafy green vegetables such as spinach and kale contain lutein and zeaxanthin, nutrients that support macular health. Limiting saturated fats and processed foods may also be beneficial.
If you smoke, quitting is the single most important step you can take to protect your vision. A retina specialist or primary care doctor can help connect you with resources to support smoking cessation.
Low vision rehabilitation can help you make the most of your remaining vision. A low vision specialist can assess your needs and recommend tools and techniques. Helpful adaptive strategies include:
- Magnifying glasses or electronic magnifiers for reading
- Large-print books, phones, and remote controls
- Adjustable task lighting to improve contrast
- Audiobooks and screen-reading software
- High-contrast labels for household items
Living with vision loss can lead to feelings of frustration, anxiety, or sadness. These reactions are normal. Connecting with a support group for people with AMD can provide encouragement and practical advice. If feelings of depression or isolation persist, consider speaking with a counselor experienced with vision-related challenges.
AMD does not have to mean giving up the activities you enjoy. Many people with AMD continue to exercise, cook, travel, and socialize with the right adaptations. Occupational therapists can teach techniques for safely navigating your home. Maintaining physical activity also supports cardiovascular health, which may benefit your eye health.
When to See a Retina Specialist
If you have been diagnosed with any stage of AMD, regular visits with a retina specialist are essential. Your specialist will determine the right schedule based on the type and severity of your AMD. Even if your vision seems stable, regular imaging can catch subtle changes before you notice symptoms.
Contact a retina specialist or go to the emergency room immediately if you experience any of the following:
- Sudden increase in blurriness or dark spots in central vision
- Straight lines that suddenly appear wavy or distorted
- A new dark or blank area in the center of your vision
- Rapid decrease in your ability to see details or colors
These changes can signal the onset or worsening of wet AMD. Prompt treatment within days can make a significant difference in preserving vision.
Your optometrist or general ophthalmologist may be the first to detect signs of AMD during a routine exam. They can refer you to a retina specialist for advanced diagnosis and treatment. Maintaining relationships with all of your eye care providers helps ensure appropriate care for your situation.
Questions and Answers
AMD affects central vision but does not cause total blindness. Side vision, also called peripheral vision, is typically preserved even in advanced stages. While central vision loss can affect tasks like reading and driving, most people with AMD retain enough peripheral vision to remain mobile and independent with adaptive tools and low vision rehabilitation.
Treatment for wet AMD is typically ongoing. Many patients require injections for years to keep the disease controlled. Your retina specialist will work to find the longest safe interval between treatments. Some patients can gradually extend the time between injections. Stopping injections without guidance from your specialist can allow the disease to reactivate.
Current evidence from the AREDS2 study (NEI, 2013) supports supplement use for people with intermediate AMD or advanced AMD in one eye. There is no proven benefit for those with only early AMD or for family members without signs of the disease. Your retina specialist can help determine whether AREDS2 supplements are right for your stage of AMD.
While there is no way to reverse AMD, several steps may help slow progression. Quitting smoking is the most impactful lifestyle change. Eating a nutrient-rich Mediterranean diet, maintaining a healthy weight, controlling blood pressure and cholesterol, and protecting your eyes from UV light are all beneficial. Following your retina specialist's treatment plan and attending monitoring appointments are equally important.
Current treatments focus on slowing progression and stabilizing vision rather than restoring what has been lost. Anti-VEGF injections can sometimes improve vision in wet AMD, particularly when started early. Research into new therapies, including gene therapy, is ongoing but still in clinical trials. Staying engaged with your retina specialist ensures you can access new options as they become available.
