Intravitreal Injections
Intravitreal injections are a type of treatment that involves administering medication directly into the vitreous humor, the gel-like substance in the middle of the eye. This method allows for targeted delivery of medication to treat a variety of eye conditions. Intravitreal injections have become increasingly important for managing retinal conditions. Retinal diseases such as age-related macular degeneration (AMD), diabetic retinopathy and retinal vein occlusion can cause profound and irreversible vision loss if left untreated. Intravitreal injections can help slow down or even reverse the progression of these diseases, preserving and improving vision for patients.

Understanding Intravitreal Injections: Benefits, Risks, Preparation and Treatment Options
How Do Intravitreal Injections Work?
Intravitreal injections work by delivering medication directly into the vitreous humor, bypassing other barriers that may hinder drug absorption. A very fine needle is used to inject the medication into the back of the eye. The medication then spreads throughout the vitreous humor, reaching the retina and exerting its therapeutic effects. The medication used in intravitreal injections depends upon the condition being treated. Anti-vascular endothelial growth factor (VEGF) drugs are commonly used to inhibit abnormal blood vessel growth and reduce inflammation in the eye.
Risks and Complications of Intravitreal Injections
Intravitreal injections are generally safe and well-tolerated, however there are potential risks and complications associated with the procedure. The most common side effects include temporary discomfort, redness, and increased floaters in the vision. Rarely, more serious complications including loss of vision, infection, retinal detachment, and increased eye pressure can occur. The procedure is recommended when the benefits outweigh the risks. It is important to discuss any concerns with your ophthalmologist before undergoing the procedure.
Preparing for an Intravitreal Injection
Before undergoing an injection, your ophthalmologist will provide specific instructions on how to prepare for the procedure. We recommend that you arrange transportation to and from the clinic for the procedure. Dr Mitch will also discuss the potential risks and benefits of the injection and address any questions or concerns you may have.
What to Expect During the Procedure
During the procedure, you will be positioned comfortably in a reclining chair. At Eagle Eye Surgeons we understand that patients can feel very anxious before an intravitreal injection. Our staff and surgeons always aim to make the experience as comfortable and reassuring as possible. Your eye will be numbed with local anesthesia to minimize any discomfort. The ophthalmologist will then use a sterile technique to administer the injection. You may feel a slight pressure or a sensation of warmth during the injection, but it should not be painful. You will not see the needle coming toward you, it is kept away from your view for your comfort. The entire procedure typically takes only a few minutes, and you will be able to go home shortly afterward.
Recovery and Aftercare Following an Intravitreal Injection
After the injection, your ophthalmologist may provide specific post-procedure instructions to promote healing and minimize the risk of complications. These instructions may include avoiding strenuous activities, refraining from rubbing or touching your eye, and using prescribed eye drops or ointment as directed. It is important to attend any scheduled follow-up appointments to monitor your progress and ensure the treatment is working effectively.
