Intravitreal Injections

Intravitreal injections are a common and effective treatment for various retinal conditions. In this procedure, medication is injected directly through the sclera (the white part of the eye) into the vitreous (the gel-like substance filling the inside of the eye) to help improve or stabilize vision. Intravitreal injections are typically administered in an office setting using local anesthesia.

Depending on the specific condition being treated, you may need these injections as often as once a month. The most common type of intravitreal injection contains anti-vascular endothelial growth factor (anti-VEGF) medication. However, retina specialists may also provide steroids and antibiotics for the eye as needed.

Anti-Vascular Endothelial Growth Factor Injections

The most common medications used for intravitreal injections are the anti-VEGF class of drugs. These medications work by blocking the proteins responsible for abnormal blood vessel formation.

Common anti-VEGF drugs include:

• Vabysmo
• Eylea
• Eylea HD
• Lucentis
• Pavblu

Conditions Treated With Intravitreal Injections

Your retina specialist will usually recommend intravitreal injections for conditions that cause abnormal blood vessels to form in the retina. These blood vessels can leak fluid and blood, potentially leading to vision loss. Common conditions treated with intravitreal injections include:

• Wet age-related macular degeneration (AMD)
• Diabetic retinopathy
• Retinal vein occlusion
• Macular edema

Intravitreal Injections: What to Expect

Intravitreal injections may seem intimidating, but the process is quick and generally painless. Before the injection, your retina specialist will numb your eye with anesthetic drops and apply an antiseptic solution to ensure sterility.

During the procedure, an eyelid speculum is typically used to keep your eyelids open. You'll be instructed to gaze in a specific direction depending on where the injection will be given. The medication is then injected through the white part of your eye using a very small needle. Most patients report only mild pressure during the injection.

Intravitreal Injections Recovery

You should be able to resume normal activities fairly quickly after receiving intravitreal injections. Some patients may experience minor eye irritation or notice a small spot of blood in their eye, but this is normal and usually resolves on its own. Sterile artificial tears can be used to ease any symptoms of dryness and surface irritation.

Long-Term Effectiveness of Intravitreal Injections

With consistent therapy, most patients can maintain their vision for years. However, long-term outcomes rely heavily on consistent adherence to treatment. Your retina specialist will develop a personalized treatment schedule to ensure the best vision outcomes tailored to your unique condition.
