Anti-VEGF therapy is a vital approach for managing retinal conditions marked by abnormal blood vessel growth. With specialists listed on Specialty Vision, you can find a top optometrist to discuss effective treatment options tailored to your eye health needs.
Anti-VEGF medications are a key treatment for retinal conditions that involve abnormal blood vessel growth. By blocking a protein called VEGF, which can trigger leakage and swelling in the eye, these injections help prevent vision loss and, in many cases, improve visual clarity. Retina specialists rely on anti-VEGF therapy as a safe, targeted, and effective way to manage sight-threatening diseases and support long-term eye health.
Anti-VEGF stands for anti–vascular endothelial growth factor, a treatment that blocks VEGF—a protein in the body that promotes new blood vessel growth. While VEGF is helpful in healing processes like tissue repair, excessive VEGF in the eye can lead to the formation of abnormal blood vessels beneath the retina. These vessels are fragile and can leak fluid or blood, causing swelling and vision damage.
This process plays a key role in diseases such as wet age-related macular degeneration (AMD), diabetic retinopathy, and macular edema. In these conditions, anti-VEGF injections help by neutralizing VEGF in the eye, preventing abnormal vessel growth, reducing leakage, and protecting the retina. These treatments have become a central part of managing and preserving vision in patients with retinal disease.
Anti-VEGF medications block the activity of VEGF, a protein that causes abnormal blood vessels to grow and leak beneath the retina. These medications bind to VEGF with high precision, stopping it from triggering the formation of new, harmful vessels.
By preventing this abnormal growth, anti-VEGF therapy helps reduce swelling, stabilize vision, and in some cases, improve visual clarity. The treatment also helps protect the retina from further damage caused by fluid accumulation.
These medications are delivered directly into the vitreous—the gel-like substance inside the eye—to ensure that the treatment targets only the affected area. This localized approach limits exposure to the rest of the body, allowing normal VEGF activity to continue in other tissues where it supports healing.
Wet AMD occurs when abnormal blood vessels grow under the macula, which is responsible for clear central vision. These vessels leak fluid, leading to rapid vision loss. Anti-VEGF treatments help stop the growth of these vessels and preserve vision.
RAP is a form of wet AMD where abnormal blood vessels form within the retinal layers. These vessels leak fluid and blood, leading to distortion and loss of central vision. Anti-VEGF treatments reduce leakage and prevent further abnormal vessel growth.
PCV is a condition where abnormal blood vessels grow under the retina, often forming polyp-like structures. These structures leak or bleed, causing vision problems. Anti-VEGF therapy helps by reducing abnormal vessel activity and improving vision outcomes.
In individuals with high myopia (severe nearsightedness), abnormal blood vessels may grow under the retina, leading to fluid leakage and distorted vision. Anti-VEGF injections can help stop the growth of these abnormal vessels and preserve central vision.
In some cases, abnormal blood vessel growth under the retina occurs without an identifiable cause, leading to symptoms similar to wet AMD. Anti-VEGF therapy can reduce vessel leakage and stabilize vision.
DME is a complication of diabetes that causes fluid to leak into the macula, leading to swelling and blurry vision. Anti-VEGF injections help reduce the leakage and swelling, maintaining better vision.
RVO occurs when a blood clot blocks the retinal veins, causing fluid buildup and swelling. Anti-VEGF therapy helps reduce swelling and improves vision.
Branch Retinal Vein Occlusion (BRVO): A partial blockage of the retinal vein affects a portion of the field of vision.
Central Retinal Vein Occlusion (CRVO): The main retinal vein is blocked, leading to widespread vision loss. Anti-VEGF helps reduce swelling and improve vision.
Uveitis causes inflammation of the eye, which can lead to macular edema. If other treatments are ineffective, anti-VEGF therapy can reduce swelling and preserve vision.
Infections like toxoplasmosis can cause lesions in the retina, triggering abnormal blood vessel growth. Anti-VEGF therapy may help manage these secondary effects by reducing vessel leakage.
ROP affects premature infants, causing abnormal blood vessels to grow in the retina. Anti-VEGF injections can help control this growth and prevent long-term vision damage.
Choroidal hemangiomas are benign tumors in the eye that can leak fluid and lead to retinal detachment. Anti-VEGF therapy may help reduce leakage and stabilize vision.
It’s normal to feel uneasy about an eye injection, but the procedure is quick and generally well tolerated. Before the injection, your eye is disinfected and numbed with anesthetic drops to minimize discomfort.
A small device called a speculum is used to keep your eyelids open. The anti-VEGF medication is then injected through the white part of your eye (the sclera) into the vitreous gel. The injection itself takes only a few seconds and typically causes just mild pressure, not pain.
Afterward, your eye is rinsed with a saline solution. You may notice slight irritation, blurred vision, or floaters for a day or two, but these symptoms usually resolve on their own.
Anti-VEGF therapy involves a series of injections over time—not a one-time treatment. Most patients start with a loading phase of three monthly injections to build effectiveness. After that, injection intervals typically range from every four to six weeks, and may be extended depending on how your condition responds.
Your treatment plan is personalized. Retina specialists monitor your progress using imaging tools like optical coherence tomography (OCT), which provides detailed views of the retina. These scans help determine how often injections are needed and guide any adjustments.
The main goal is to stabilize your vision and prevent further damage. Some patients experience improvement, while others maintain their current vision. Staying on schedule with your injections is essential to getting the best results.
Treatment begins with a consultation, where your retina specialist will explain the procedure, review potential risks and benefits, and answer any questions.
The injection process is straightforward and designed with your safety and comfort in mind. Key steps include:
The full visit takes about 10 to 15 minutes, though the injection itself lasts only a few seconds.
After the procedure, you may experience mild irritation, blurred vision, or floaters, but these usually improve within a day or two. Your retina specialist may advise avoiding certain activities, like driving, and recommend keeping the eye clean and dry for the first 24 hours.
There are several anti-VEGF medications that can help treat retinal conditions, such as wet macular degeneration (AMD) and diabetic macular edema (DME). Each medication has its own features, but they all work by blocking VEGF, a protein that causes abnormal blood vessels in the eye. It is important to note that no one option is best for everyone, and our retina specialist will guide you on the best option for your condition and needs.
