AMD Treatment Options: Dry, Wet, and Geographic Atrophy
Treatments for Dry AMD
Dry AMD is the most common form of the disease, affecting the majority of patients diagnosed with AMD. While dry AMD tends to progress more slowly than the wet form, it still requires active management to protect your remaining vision and reduce the risk of advancing to a more serious stage.
The AREDS2 formula is a specific combination of vitamins and minerals developed through large clinical research trials and shown to reduce the risk of intermediate dry AMD progressing to advanced AMD. The formula includes vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin.
Your eye care provider will tell you whether your stage of AMD qualifies you for these supplements. They are beneficial for patients with intermediate dry AMD or advanced AMD in one eye, but they have not been shown to help those with early-stage disease. Not all over-the-counter 'eye vitamin' products match the exact doses used in the trials, so ask our team to recommend a product that reflects the studied formula precisely.
Geographic atrophy (GA) is the advanced stage of dry AMD, where patches of retinal cells break down and create permanent blind spots in your central vision. Two FDA-approved medications, pegcetacoplan and avacincaptad pegol, are now available to slow the growth of these atrophic lesions.
Both medications are complement inhibitors, meaning they work by blocking a specific part of the immune system that contributes to retinal cell damage. They are delivered by intravitreal injection, which means your retina specialist administers them directly into the eye, typically on a monthly or every-other-month schedule. Neither medication restores vision that has already been lost, but slowing lesion growth can help protect the vision you still have. Your retina specialist will evaluate whether you are a candidate based on the size and location of your GA lesions.
Certain lifestyle changes can reduce your risk of AMD worsening over time. Smoking is one of the strongest modifiable risk factors for AMD progression, and quitting at any age lowers that risk. A diet rich in dark leafy greens, fatty fish, and colorful fruits provides antioxidants and nutrients that support your retina.
- Eat spinach, kale, and collard greens regularly for lutein and zeaxanthin
- Include salmon, tuna, or sardines in your diet for omega-3 fatty acids
- Wear sunglasses with UV protection when outdoors
- Manage blood pressure and overall cardiovascular health
These habits work alongside medical treatment and monitoring rather than replacing them.
Regular monitoring exams are important at every stage of AMD because dry AMD can convert to wet AMD at any point, and early detection allows for faster, more effective treatment. Our team uses optical coherence tomography (OCT) imaging, dilated retinal exams, and sometimes fundus photography to closely track changes in your macula, the central part of your retina responsible for sharp detail vision.
At home, you can use an Amsler grid, a simple checkerboard pattern, to check for new distortion or blind spots between appointments. If anything looks different, contact us promptly rather than waiting for your next scheduled visit.
Treatments for Wet AMD
Wet AMD occurs when abnormal blood vessels grow beneath the retina and leak fluid or blood, causing rapid central vision loss. It requires active, ongoing treatment to stabilize vision. The good news is that effective therapies exist, and most patients who receive consistent care are able to protect much of their remaining vision.
Anti-VEGF therapy is the standard first-line treatment for wet AMD. These medications block vascular endothelial growth factor (VEGF), the protein responsible for triggering the abnormal blood vessel growth that causes leaking and retinal damage. Available medications include aflibercept, ranibizumab, faricimab, and bevacizumab, each administered by intravitreal injection directly into the eye by your retina specialist.
Anti-VEGF treatment stabilizes or improves vision in the large majority of patients with wet AMD. Treatment typically begins with a series of monthly injections during what is called a loading phase, followed by a personalized maintenance schedule based on how your retina responds. Most patients require ongoing injections over the long term to keep the disease controlled.
Treat-and-extend is the most widely used approach for scheduling anti-VEGF injections over time. Your retina specialist gives an injection at every visit, and if your retina remains stable and dry on OCT imaging, the interval between visits is gradually extended in two-week increments. Some patients are able to space out injections to every 10 to 12 weeks, reducing the number of trips to the clinic each year.
If fluid returns on imaging, the interval is shortened to regain control of the disease before extending again. This approach is designed to balance effective disease management with a more flexible visit schedule for patients.
Photodynamic therapy (PDT) uses a light-activated medication combined with a precisely targeted laser to close abnormal blood vessels beneath the retina. The medication is injected into a vein in the arm, allowed to concentrate in the abnormal vessels, and then activated by a low-energy laser directed at the retina. PDT is no longer the primary treatment for most wet AMD patients, but it remains a useful option for certain vessel subtypes or in combination with anti-VEGF therapy for cases that do not respond to injections alone.
Following PDT, patients must avoid direct sunlight and bright indoor lighting for five days because the medication causes temporary sensitivity to light.
Your retina specialist selects a treatment plan based on the type and location of your abnormal blood vessels, your imaging results, your history of prior treatments, and practical factors such as how often you are able to come in for appointments. Anti-VEGF injections are the starting point for nearly all wet AMD patients. If one medication does not adequately control your disease, your doctor may switch to a different anti-VEGF agent or incorporate PDT into your plan.
Newer agents such as faricimab offer the potential for extended dosing intervals in some patients, which can meaningfully reduce the burden of frequent clinic visits. Our retina specialists, Dr. Gaurav Gupta and Dr. Pranjal Thakuria, will discuss which approach fits your specific situation best.
Living With AMD
An AMD diagnosis changes the way you think about your vision, but it does not mean losing your independence. Understanding what AMD affects and learning how to adapt gives you the best foundation for living well with the condition.
AMD affects your central vision, the sharp, focused sight you use for reading, recognizing faces, and seeing fine details. It does not cause complete blindness. Your peripheral (side) vision remains intact even in advanced stages of the disease, and most people with AMD are still able to move around safely, care for themselves, and stay active with appropriate support.
If AMD has reduced your central vision, low-vision specialists can help you make the most of the vision you still have. A range of practical tools and techniques can help you maintain independence and continue doing the activities that matter most to you.
- Handheld or stand magnifiers for reading labels, mail, and menus
- Electronic magnification devices with adjustable contrast and brightness
- Task lighting positioned to reduce glare and improve contrast
- Large-button phones, talking watches, and screen-reading applications
Vision rehabilitation programs can also teach practical strategies for daily tasks such as cooking, managing medications, and navigating your home safely.
Certain changes in your vision are warning signs that warrant immediate attention, not a wait until your next scheduled appointment. Contact our office right away if you notice any of the following:
- A sudden increase in distortion when you check your Amsler grid
- New dark or blurry spots appearing in your central vision
- Straight lines that look wavy or bent
- A rapid change in your ability to read or recognize faces
These symptoms can indicate that dry AMD has converted to wet AMD, which requires prompt evaluation and treatment. Waiting can lead to more severe vision loss that may not be recoverable.
Frequently Asked Questions
These answers are meant to help you make informed decisions about your AMD care and know when to take action.
No currently approved treatment reverses AMD or restores vision that has already been lost to the disease. The goal of treatment is to slow or halt progression and protect the vision you still have. For wet AMD, anti-VEGF injections can stabilize and in some cases partially improve vision, but they manage the condition rather than eliminate it. Research into approaches such as gene therapy and cell-based treatments is ongoing, and your retina specialist can discuss whether any emerging options may be relevant to your case.
Your eye care provider determines your AMD type through a dilated eye exam and imaging. Dry AMD is identified by drusen, which are small yellow deposits beneath the retina, and may also include areas of geographic atrophy. Wet AMD is distinguished by the presence of fluid or blood from abnormal blood vessel growth. OCT imaging reveals these features in precise detail. It is also possible to have dry AMD in one eye and wet AMD in the other, which is why both eyes are monitored at every visit.
AREDS2 supplements are available without a prescription, but they are not appropriate for everyone with AMD. They are specifically beneficial for patients with intermediate dry AMD or advanced AMD in one eye, and they have not been shown to help those with early-stage disease or no AMD at all. Some of the supplement's ingredients, particularly zinc, can interact with certain medications or affect people with specific health conditions. Always ask your eye care provider before starting supplementation to confirm your stage of disease and to identify the right product and dose for you.
Delaying treatment for wet AMD allows fluid and blood to accumulate beneath your retina, which can lead to scarring and permanent vision loss. Even a gap of a few weeks beyond your scheduled interval can allow the disease to become more active. If you stop injections without guidance from your retina specialist, the abnormal blood vessels can reactivate and begin leaking more aggressively than before. If scheduling or travel is a barrier, speak with our team so we can find a solution that keeps your care on track.
Yes, and we encourage it. The Amsler grid is a simple tool you can use at home to check your central vision for new distortion, waviness, or blank spots. Testing each eye separately, with your reading glasses if you wear them, takes less than a minute. If something looks different from one day to the next, that is a reason to call us promptly rather than wait. Home monitoring does not replace your scheduled imaging exams, but it adds an important layer of self-awareness between visits.
Yes, though they work best as a complement to medical treatment rather than a substitute for it. Quitting smoking is the single most impactful lifestyle change you can make for your retinal health, as smoking significantly increases the rate at which AMD progresses. A diet rich in lutein, zeaxanthin, and omega-3 fatty acids supports the health of retinal cells over time. Protecting your eyes from UV exposure and managing systemic conditions such as high blood pressure also contribute to better long-term outcomes. These steps matter at every stage of AMD and are part of the care plan we discuss with every patient.
