Anti-VEGF Injections for Wet Age-Related Macular Degeneration
Why Your Eye Doctor Recommends Anti-VEGF Injections
Wet age-related macular degeneration happens when fragile new blood vessels grow beneath the macula, the part of your retina responsible for sharp central vision. These abnormal vessels leak fluid and blood into the layers of your retina, causing swelling and damage to the cells you need for reading, recognizing faces, and seeing fine detail.
Without treatment, this leakage can lead to permanent scarring and severe vision loss, often within weeks or months, though the pace of progression varies. The central blind spot that develops makes everyday tasks like driving, cooking, and reading extremely difficult or impossible.
Wet age-related macular degeneration often develops suddenly and progresses rapidly. You may notice straight lines appearing wavy or bent, a dark or blurry spot in the center of your vision, or colors seeming less vivid than before.
- Sudden distortion where straight edges look curved or crooked
- A growing gray or dark area blocking your central vision
- Blurriness that makes it hard to see faces or read even with glasses
- Difficulty adjusting to low light or needing brighter lighting than usual
Anti-VEGF therapy targets the root cause of wet age-related macular degeneration by blocking vascular endothelial growth factor, a protein that signals your body to create the harmful new blood vessels. By stopping this signal, we can halt abnormal vessel growth and reduce the leakage that damages your retina.
Studies consistently show that anti-VEGF injections are far more effective than older treatments and are the standard of care in 2025 for wet age-related macular degeneration. Many patients maintain or even improve their vision when treatment begins early and continues on schedule.
Untreated wet age-related macular degeneration commonly leads to severe central vision loss, often progressing over weeks to months, though the timeline and severity can vary. The leaking blood vessels continue to damage the macula, creating permanent scar tissue that cannot be repaired even with later treatment.
Once scarring occurs, the vision loss becomes irreversible. Starting anti-VEGF therapy as soon as we diagnose wet age-related macular degeneration gives you the best chance of preserving the sight you still have and possibly regaining some vision that has recently declined.
The Anti-VEGF Medications and How They Work
Several anti-VEGF medications are approved and used widely for wet age-related macular degeneration treatment in 2025. The most commonly used drugs include aflibercept, ranibizumab, brolucizumab, and faricimab, each with slightly different formulations and treatment schedules. Bevacizumab is also commonly used off-label as an effective and often lower-cost option, and your choice of medication may depend on clinical factors, insurance coverage, and cost considerations.
All of these medications work through the same basic mechanism of blocking VEGF, but some offer longer-lasting effects or may work better for certain patients. Newer formulations such as higher-dose aflibercept (8 mg) may allow for extended intervals between injections in some practices, and ranibizumab biosimilars are also available in some regions. Our eye doctor will select the best option based on your individual condition and response to treatment.
Brolucizumab has been associated with higher rates of intraocular inflammation and rare but serious events including retinal vasculitis and retinal vascular occlusion. If this medication is recommended for you, your ophthalmologist will discuss these risks and monitor you closely during treatment.
When we inject the anti-VEGF medication into your eye, it binds to VEGF proteins that are circulating in the fluid inside your eye. By blocking these proteins, the drug prevents them from attaching to receptors on abnormal blood vessels and sending growth signals.
- The medication reduces leakage from existing abnormal vessels within days
- New abnormal blood vessel growth stops because the growth signal is blocked
- Fluid that has built up in your retina can drain away and vision may improve
- The drug gradually wears off over weeks, which is why repeat injections are needed
We consider several factors when selecting which anti-VEGF drug to use for your treatment. These include the severity of fluid leakage in your retina, how quickly we need to control the disease, your overall health conditions, the safety profile of each medication, and how frequently you can return for appointments.
Some newer medications allow for longer intervals between injections once your condition stabilizes, which may reduce the number of visits you need each year. We may also switch medications if your initial treatment does not control the leakage as well as we expect.
Preparing for and Receiving Your Anti-VEGF Injection
Before each injection, we typically perform optical coherence tomography, a special imaging test that creates detailed cross-sectional pictures of your retina. This scan shows us exactly how much fluid is present and whether the previous treatment successfully reduced leakage.
We may also use fluorescein angiography or other imaging techniques during your initial visits or if we need to evaluate changes in your condition. These tests help us measure your response to treatment and decide when you need your next injection.
The thought of an injection in your eye can sound frightening, but we take several steps to ensure you feel little or no pain. We apply numbing drops to the surface of your eye multiple times before the procedure, which blocks most sensation in the area where the needle enters.
- Topical anesthetic drops numb the surface of your eye very well within minutes
- We may also use a numbing gel that stays on the eye surface longer
- You remain awake during the procedure and can communicate with us
- Most patients report feeling only mild pressure rather than pain
After your eye is numb, your ophthalmologist cleans the surface with an antiseptic solution to prevent infection. A very thin needle is used to inject the medication through the white part of your eye into the vitreous cavity, the gel-filled space in the center of your eyeball.
The actual injection takes only a few seconds. We hold your eyelids open with a gentle speculum so you cannot blink, and we ask you to look in a specific direction to position your eye correctly for the safest injection site.
Plan for your entire visit to last about one to two hours, although the injection itself is very quick. Most of the appointment time involves checking your vision, performing imaging scans, dilating your pupil if needed, and allowing the numbing drops to work.
After the injection, we may check your eye pressure and examine your eye briefly before you leave. You will spend only a few minutes in the procedure area, with most of your time in the examination and waiting areas.
During the injection, you may see a brief shadow or dark spot as the medicine enters your eye, or you might notice a slight sensation of fullness or pressure. Some patients see floaters or bubbles in their vision immediately afterward, which is very common and expected.
- A temporary shadow or darkness that passes within seconds
- The feeling of something touching your eye, but not sharp pain
- Floaters or small spots that drift across your vision afterward
- Mild scratchiness or grittiness from the antiseptic cleaning solution
Recovering After Your Anti-VEGF Injection
Your eye may feel mildly irritated, scratchy, or somewhat gritty for the first day or two after your injection. You might also notice the white part of your eye looks slightly red or bloodshot where the needle entered, which is a harmless small bleed that clears up on its own within a week or two.
Floaters in your vision are very common right after the injection and usually settle or fade over the next few days. Your vision may be temporarily blurry, especially if we dilated your pupil, but this typically improves within 24 hours. If you notice a sudden shower of many new floaters, contact us right away.
We may recommend using artificial tears several times a day if your eye feels dry or scratchy. Avoid rubbing your eye, even if it feels irritated, because this increases the risk of infection or irritation. Not all practices routinely prescribe antibiotic eye drops after injections, but if we give them to you, use them exactly as directed.
- Keep your eye clean and avoid touching it with unwashed hands
- Avoid wearing eye makeup for at least 24 hours after your injection
- You can usually resume wearing contact lenses the next day unless instructed otherwise
- Avoid swimming or soaking your head underwater for several days
- Wear sunglasses if bright light bothers you while your pupil is dilated
Most patients can return to normal activities the day after their injection, although some prefer to rest the remainder of the day following treatment. You can generally resume work, light exercise, reading, and screen time as soon as you feel comfortable.
You may be advised to avoid strenuous exercise, heavy lifting, or activities that dramatically raise your blood pressure for 24 to 48 hours after the injection, depending on your individual situation. Showering and normal face washing are generally fine, but avoid getting contaminated water directly into your eye for the first day or two.
While complications are rare, infections and other serious problems can occur after any eye injection. Contact our office immediately or seek emergency eye care if you develop worsening pain, severe redness, increasing vision loss, or other concerning symptoms.
- Pain that gets worse instead of better after the first day
- Sudden significant decrease in your vision
- Increased redness, pus-like discharge, or swelling of your eyelid
- Marked sensitivity to light with worsening redness or pain
- New flashing lights in your vision
- A curtain or shadow moving across your field of vision
- A sudden shower of many new floaters
Your Ongoing Treatment Schedule and Monitoring
Anti-VEGF therapy is not a one-time treatment. Most patients need ongoing injections for months or years to keep wet age-related macular degeneration under control because the medication gradually wears off and abnormal blood vessels can become active again.
The frequency of your injections depends on which drug we use, how your eye responds to treatment, and whether fluid returns between doses. Treatment schedules in 2025 are often personalized based on your individual disease activity rather than following a rigid timetable.
Treatment typically begins with a loading phase, during which you receive injections at regular intervals for the first few months. This initial intensive treatment helps quickly reduce the fluid and give you the best chance at vision improvement.
After the loading phase, we transition to a maintenance phase where the goal is to prevent fluid from returning. Common maintenance approaches include fixed dosing at set intervals, as-needed treatment based on disease activity, or treat-and-extend schedules where we gradually increase the time between visits as long as your retina remains dry. Many patients are managed with treat-and-extend protocols once their condition stabilizes.
At each follow-up visit, we check your vision and perform imaging scans to look for any signs that fluid is returning. These monitoring appointments are just as important as the injection visits because they tell us whether your treatment is working and when you need your next dose.
We also ask you to monitor your own vision at home between appointments using an Amsler grid, a simple chart with a grid pattern. If you notice new distortion or changes in the lines on the grid, contact us right away because it may signal that fluid is building up again.
If your retina stays dry on imaging scans for several visits in a row, we may extend the time between injections to see how long the treatment effect lasts for you. Some patients can go eight, twelve, or even sixteen weeks between injections once their condition stabilizes.
- We gradually increase the interval between treatments if your eye remains stable
- If fluid returns, we shorten the interval or consider switching medications
- Your personal treatment schedule is based on your response, not a fixed protocol
- Regular imaging at every visit guides these scheduling decisions
We understand that life sometimes interferes with medical appointments, but delaying your scheduled injection can allow fluid to return and put your vision at risk. If you must reschedule, contact our office as soon as possible so we can book you for the earliest available alternative date.
Try to avoid delays longer than one or two weeks beyond your scheduled appointment. If you notice vision changes while waiting for a rescheduled appointment, let us know immediately because we may need to see you sooner than your new appointment date.
While anti-VEGF injections are the primary treatment for wet age-related macular degeneration, other options and support services may be part of your care plan depending on your individual needs and response to therapy.
- Switching to a different anti-VEGF medication if your current drug is not controlling fluid well
- Photodynamic therapy in selected cases when anti-VEGF alone is not sufficient
- Low vision rehabilitation and assistive devices if central vision remains reduced despite treatment
- Lifestyle counseling including smoking cessation and cardiovascular risk management as adjuncts to medical therapy
- AREDS2 nutritional supplements may be recommended depending on the status of your other eye and overall macular health
Frequently Asked Questions
Many patients experience some vision improvement during the first few months of treatment as the medication reduces fluid and swelling in the retina. However, anti-VEGF therapy cannot reverse permanent damage or scarring that occurred before treatment started, so the main goal is usually to stabilize your vision and prevent further loss.
Most patients describe the injection as far less painful than they expected. The numbing drops work very well, and you typically feel only mild pressure or a brief sensation of something touching your eye rather than actual pain.
We generally recommend arranging a ride home because your vision may be temporarily blurry from dilating drops or from the injection itself. Your eye may also feel slightly uncomfortable, and you may have floaters that distract you while driving.
Many patients with wet age-related macular degeneration require ongoing treatment for years to keep the abnormal blood vessels from becoming active again. Some patients eventually develop stable inactive scarring and can stop injections, while others need continued treatment indefinitely to preserve their vision.
If your current medication no longer controls the fluid leakage as well as it did initially, we can switch you to a different anti-VEGF drug that may work better for you. We monitor your response closely at every visit so we can make these adjustments before you lose significant vision.
Serious complications from anti-VEGF injections are uncommon but can include infection inside the eye called endophthalmitis, which typically develops within a few days and requires urgent treatment. Other risks include bleeding inside the eye, elevated eye pressure especially in patients with glaucoma or ocular hypertension, retinal detachment, and intraocular inflammation. Certain medications such as brolucizumab carry a higher risk of inflammation and rare retinal vascular events.
Very rare systemic risks such as stroke or heart attack have been reported, and your ophthalmologist will weigh these risks carefully, especially if you have had recent cardiovascular events. If you are pregnant, planning pregnancy, or breastfeeding, discuss these considerations with your doctor, as anti-VEGF medications are generally used with caution in these situations. We take careful sterile precautions to minimize infection risk and monitor you closely for any signs of problems during your recovery.
