Genetic testing for AMD can help clarify your risk profile and guide your eye care decisions. Our retina specialists are ready to support you in navigating this complex decision and offer tailored advice based on your individual circumstances.
Age-related macular degeneration (AMD) is a complex retinal condition influenced by both genetic and environmental factors. Advances in research have sparked interest in genetic testing as one way to understand personal risk. This page explains the role of genetics in AMD and when it might be helpful to discuss testing with our retina specialists.
AMD affects the macula, the part of the retina that gives you sharp, central vision. It comes in two main forms: dry AMD, which progresses slowly, and wet AMD, which can cause rapid, severe vision loss due to abnormal blood vessel growth. Research has linked several genetic variants — including changes in genes like CFH and ARMS2 — to a higher risk of developing AMD. Many of these genes are tied to immune response and inflammation.
Having these genetic variants doesn’t mean you will definitely develop AMD. Your actual risk depends on a mix of genetics, lifestyle choices, and environmental factors like smoking, diet, and blood pressure. When considering genetic testing, retina specialists look at both genetic markers and other risk factors to give you the best advice.
Genetic testing may place you into low, moderate, or high-risk categories. While helpful for understanding your overall risk, it’s not a guarantee of getting AMD or a direct guide for treatment decisions.
Genetic testing for AMD is straightforward and usually involves a cheek swab or a blood sample. These samples are sent to a lab to check for gene variants linked to a higher risk of developing AMD. Most tests focus on genes tied to the complement system and the ARMS2/HTRA1 region, giving a probability-based risk estimate.
It’s important to know that genetic testing doesn’t diagnose AMD. It only shows whether your risk is higher or lower based on your genes. Right now, treatment decisions for dry and wet AMD are based on clinical exams, imaging results, and personal history — not genetics alone.
When you talk with a retina specialist about genetic testing, they’ll explain that it’s a tool for predicting risk, not for making a diagnosis. A high-risk result doesn’t guarantee you’ll develop AMD, and a low-risk result doesn’t rule it out if other factors are involved.
If a close relative — like a parent or sibling — developed AMD, especially before age 65, you may have a higher genetic risk. In this case, talking with a retina specialist about genetic testing can help you better understand your personal risk. Knowing this could encourage more regular eye exams and earlier preventive steps.
If you already have early signs of AMD, like drusen or pigment changes in the retina, genetic testing might offer more information when combined with your exam findings. In some cases, testing can also help determine if you qualify for research studies focused on new treatments. If you're noticing early changes, your retina specialist may suggest including genetic testing in your care plan.
Even though current treatments don’t change based on genetic results, knowing your genetic risk can motivate healthier choices. Some patients find that learning about a high risk encourages better habits, like improving their diet or avoiding smoking — both important for protecting vision.
Genetic testing mainly helps predict risk but doesn’t guide treatment decisions. Whether your genetic risk is high or low, managing AMD still depends on clinical exams, imaging, and your overall health — not just genetic results.
Learning you have a high genetic risk can cause anxiety, especially if you don’t have symptoms yet. A low-risk result might create a false sense of security and lead to skipping important check-ups. It’s important to be aware of these emotional impacts before testing.
Most insurance plans don't cover genetic testing for AMD. Privacy is also a factor — while federal laws protect against genetic discrimination, it’s important to understand exactly what those protections do (and don’t) cover.
Many direct-to-consumer tests offer AMD risk reports, but their accuracy and reliability vary. Talking with a retina specialist ensures you use trusted labs and that your results are interpreted correctly, based on your full eye health picture.
If you have a family history of AMD or early signs of retinal changes, consider scheduling a consultation with our experienced retina specialists. They can guide you through the genetic testing process and help make personalized recommendations for your vision care.
Genetic testing is just one part of understanding and managing AMD. Our retina specialists take a full view of your risk by combining eye exams, family history, lifestyle factors, and genetic information. They assess whether testing makes sense for your specific situation.
Retina specialists interpret your genetic results alongside clinical findings to give you a complete view of your risk — not just what the test shows on its own.
They explain what your genetic risk means in simple terms, helping you make informed choices about your eye care.
If your risk is higher, they may recommend more frequent check-ups or lifestyle changes to help protect your vision.
When needed, our retina specialists partner with genetic counselors to offer a deeper understanding of your results. This teamwork helps you get clear, personalized advice so you can take proactive steps for your eye health.
Choosing to have genetic testing is a personal decision that should be made with guidance from a retina specialist. If you’re thinking about it, ask yourself:
