Anti-VEGF injections

What are anti-VEGF injections?

Anti-VEGF injections are a treatment for certain retinal disorders that cause vision loss, such as wet age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusions. These injections contain medications that block a protein called vascular endothelial growth factor (VEGF), which stimulates the growth of abnormal blood vessels in the retina.

When are anti-VEGF injections used?

Your retina specialist may recommend anti-VEGF injections if you have a retinal condition that causes abnormal blood vessel growth and leakage under the retina. This can lead to swelling and damage to the light-sensitive cells, resulting in vision loss. By blocking VEGF, these medications help reduce fluid buildup and prevent further damage.

Are anti-VEGF injections safe?

While any medical procedure has some risks, anti-VEGF injections are generally considered safe when performed by an experienced eye doctor under sterile conditions. Potential side effects are rare but may include eye irritation, increased pressure in the eye, or infection. Your doctor will discuss the risks and benefits with you before treatment.

What are the different types of anti-VEGF medications?

Several anti-VEGF drugs are available, including

• Bevacizumab (Avastin)
• Ranibizumab (Lucentis)
• Aflibercept (Eylea)
• Brolucizumab (Beovu)

Your retina specialist will choose the most appropriate medication based on your specific condition and medical history.

How many injections will I need?

The number of injections required varies from person to person. Most patients start with a loading dose of 3 monthly injections, followed by ongoing treatment at regular intervals to maintain the benefits. Your doctor will determine the frequency of maintenance injections based on how your eye responds to treatment. Some people may need injections as often as every 4 weeks, while others can be extended to every 12 weeks or longer.

The importance of persistence

Receiving multiple injections over a long period can feel overwhelming, but it’s essential to stick with your treatment plan. Skipping or delaying injections allows the disease to progress and can reverse the visual improvements you’ve achieved.

As a patient, it’s crucial to work closely with your retina specialist and attend all scheduled appointments. With patience and commitment to the treatment process, anti-VEGF injections can effectively manage retinal disorders and help preserve your vision in the long term.
