Age-Related Macular Degeneration: What You Need to Know
Understanding AMD and How It Affects Vision
AMD is a disease of the retina, the light-sensitive tissue at the back of the eye. It specifically damages the macula, the small central area of the retina responsible for the sharp, detailed vision you rely on for reading, driving, and recognizing faces.
As AMD progresses, the macula deteriorates due to aging-related changes. This causes central vision to become blurry, distorted, or dark, while peripheral (side) vision typically remains intact. The disease does not cause total blindness, but it can make everyday tasks much harder.
AMD comes in two forms, and understanding the difference matters for treatment. The vast majority of AMD cases, roughly 80 to 90 percent, are the dry form, which involves the gradual buildup of small protein deposits called drusen beneath the retina and slow thinning of the macula over time.
The remaining cases are wet (neovascular) AMD, where abnormal blood vessels grow under the retina and leak fluid or blood. Wet AMD is less common but causes the majority of severe, rapid vision loss. Some patients with dry AMD eventually develop wet AMD, which is why monitoring is so important.
AMD is one of the leading causes of legal blindness in Americans aged 60 and older. Millions of adults in the United States are living with some stage of AMD, and the number is expected to grow significantly as the population ages. Early detection and consistent monitoring are essential to preserving vision for as long as possible.
Risk Factors for AMD
Some AMD risk factors are beyond your control, while others can be reduced through lifestyle choices. Knowing where you stand helps guide how often you should be screened and what steps you can take to protect your vision.
Age over 55 is the primary risk factor for AMD. A family history of the disease raises your personal risk significantly above average. People of Northern European ancestry have higher rates of AMD compared to other backgrounds. Specific genetic variants, including the CFH and ARMS2 genes, are associated with a large proportion of advanced AMD cases.
Cigarette smoking is the single strongest proven modifiable risk factor, roughly doubling AMD risk. Obesity, a diet low in leafy vegetables and fish, physical inactivity, and poorly controlled blood pressure and cardiovascular health also contribute to AMD development and progression.
Even if your age or genetics put you in a higher-risk group, addressing these lifestyle factors can meaningfully lower your overall risk.
Early AMD causes no noticeable symptoms, which is why regular eye exams are so important. Comprehensive dilated eye exams are recommended for adults over 55, particularly those who smoke or have a family history of AMD. Adults 60 and older should typically be seen annually, though your eye care provider may recommend more frequent monitoring based on your individual risk.
How AMD Is Diagnosed and Staged
Diagnosing AMD requires a thorough examination of the back of the eye using specialized tools. Staging the disease helps guide treatment decisions and determines how closely you need to be followed over time.
Our team uses a dilated fundus examination combined with optical coherence tomography (OCT) to evaluate the retina in detail. OCT is a non-invasive imaging test that produces cross-sectional pictures of the retina, revealing drusen, fluid buildup, and structural changes that cannot be seen with the naked eye. In some cases, fluorescein angiography (an imaging test that uses a special dye to highlight blood vessels) is also used to detect abnormal vessel growth in wet AMD.
AMD is classified into three stages based on the size and number of drusen deposits and the degree of retinal damage.
- Early AMD: Small to medium drusen deposits with no vision loss
- Intermediate AMD: Larger drusen and possible retinal pigment changes, sometimes with mild blurring
- Late AMD: Either geographic atrophy (advanced dry AMD with significant cell loss) or choroidal neovascularization (wet AMD) with notable central vision loss
Your stage determines which treatment approach is most appropriate and how frequently you should be monitored.
Our retina specialists, Dr. Gaurav Gupta and Dr. Pranjal Thakuria, follow the most current clinical practice guidelines for AMD diagnosis, treatment initiation, and follow-up. These guidelines are regularly updated to incorporate newly approved therapies and evolving monitoring standards, ensuring that every patient receives care aligned with the latest evidence.
Treatment Options for AMD
While there is currently no cure for AMD, there are effective treatments that can slow its progression and, in the case of wet AMD, help stabilize or improve vision. The right treatment depends on your AMD stage and type.
For patients with intermediate AMD, a specific vitamin and mineral formula known as the AREDS2 supplement has been shown to reduce the risk of progressing to advanced AMD by approximately 25 percent. The formula contains vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin in specific doses. It is important that your eye care provider confirms your AMD stage before recommending these supplements, as they are not appropriate for every patient.
Anti-VEGF (anti-vascular endothelial growth factor) intravitreal injections are the standard treatment for wet AMD. These medications are injected directly into the eye to block the growth of abnormal blood vessels and reduce leaking. Available options include ranibizumab, aflibercept, bevacizumab, and faricimab, a newer bispecific antibody that can extend treatment intervals to as long as four months for some patients.
Starting treatment promptly after a wet AMD diagnosis gives the best chance of stabilizing vision and, in many cases, achieving some improvement.
Geographic atrophy is the advanced stage of dry AMD, involving the progressive loss of retinal cells in the macula. In recent years, the FDA approved the first treatments specifically targeting geographic atrophy, pegcetacoplan and avacincaptad pegol. Both are complement pathway inhibitors delivered by intravitreal injection. They work by slowing the growth of atrophic lesions, though they do not restore lost vision. Your specialist will discuss whether you are a candidate for these treatments.
Living Well with AMD
Managing AMD goes beyond office visits and treatments. Everyday habits and home monitoring play an important role in protecting the vision you have and catching any changes early.
Quitting smoking is the most impactful lifestyle change for AMD patients and those at risk. A Mediterranean-style diet rich in leafy greens, colorful vegetables, and fish supports overall macular health. Regular physical activity, blood pressure management, and wearing UV-blocking sunglasses outdoors are also beneficial habits at every stage of AMD.
Your eye care provider may recommend daily Amsler grid monitoring, a simple home test using a grid of straight lines to check for distortion in your central vision. Always test each eye separately by covering the other eye.
- If straight lines suddenly appear wavy or bent
- If a new dark or blank spot appears in your central vision
- If your vision becomes rapidly blurry in one eye
Contact your eye doctor the same day you notice any of these changes. They can signal a conversion from dry to wet AMD, which requires urgent treatment to prevent irreversible vision loss.
If AMD has already reduced your central vision, low vision specialists can recommend magnifying devices, enhanced lighting, large-print materials, and adaptive strategies for daily tasks. Many people with AMD continue reading, cooking, and using technology with the right tools and support. Your care team can provide referrals to low vision rehabilitation services when appropriate.
Frequently Asked Questions
Here are answers to some of the questions our patients most often ask about AMD.
AMD often affects both eyes, but not always at the same stage or pace. You may have intermediate AMD in one eye and early AMD in the other. Having AMD in one eye meaningfully increases the likelihood of developing it in the other, which is why both eyes are monitored independently at every visit. Your exam schedule may differ for each eye based on the findings.
Some mild macular changes are a normal part of aging, but AMD is a distinct disease process, not an inevitable part of growing older. AMD involves drusen accumulation, retinal pigment cell damage, and sometimes abnormal blood vessel growth. Many people age into their 80s and beyond without developing AMD, particularly those with favorable genetics and healthy lifestyle habits.
Do not wait for your next scheduled appointment. Sudden distortion, a new dark spot, or rapid blurring in one eye should be evaluated the same day. These symptoms can signal wet AMD conversion, which requires urgent anti-VEGF treatment. Acting quickly is the most important step you can take to protect your vision in that situation.
There is currently no cure for AMD. However, wet AMD can often be stabilized and vision sometimes improved with consistent anti-VEGF treatment. Supplements and complement inhibitors help slow progression. Researchers are actively studying gene therapy and stem cell-based approaches, but none are commercially available as of 2026. Managing AMD is an ongoing process, not a one-time fix.
AMD results from aging-related changes to the macula and is not caused by blood sugar levels. Diabetic retinopathy develops from blood vessel damage caused by chronic high blood sugar and can affect the entire retina, not just the macula. Both conditions can cause central vision loss and both can occur in the same person, but they require different monitoring schedules, treatment approaches, and specialist involvement.
Most guidelines suggest comprehensive dilated eye exams beginning around age 55, with annual exams recommended from age 60 onward. If you smoke, have a family history of AMD, or have other risk factors, earlier and more frequent exams are advisable. Your eye care provider will tailor a screening schedule based on your full risk profile, not just your age alone.
