Anti-VEGF Injections

1️⃣ Definition

Anti-VEGF (Vascular Endothelial Growth Factor) injections are advanced treatments that block abnormal blood vessel growth and leakage in the retina.
Used for conditions like age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusion.

2️⃣ Why are Anti-VEGF Injections Performed?

Prevents vision loss caused by abnormal blood vessel growth (neovascularization).
Reduces retinal swelling and bleeding.
Stabilizes and, in some cases, improves vision.

3️⃣ Who Needs Anti-VEGF Treatment?

4️⃣ Pre-Treatment Assessment

Comprehensive eye exam with OCT (Optical Coherence Tomography) and Fluorescein Angiography to assess retinal condition.
Pupil dilation to allow detailed retinal examination.

5️⃣ Injection Process

The eye is numbed with anesthetic drops to ensure a painless experience.
A small, fine needle is used to inject the Anti-VEGF drug into the vitreous (gel-like substance in the eye).
The procedure takes only a few minutes and is done in an outpatient setting.

6️⃣ How Anti-VEGF Works

The injection blocks VEGF, a protein that causes abnormal blood vessel growth and leakage.
Helps reduce swelling, stops bleeding, and prevents further retinal damage.

7️⃣ Post-Treatment Recovery

Minimal discomfort with possible mild redness or irritation.
Patients may notice small floaters (temporary air bubbles that disappear in days).
Follow-ups are necessary for ongoing monitoring and additional injections if needed.

8️⃣ Expected Results

Prevents further vision loss in most cases.
Some patients experience significant vision improvement over time.
Requires multiple injections over months or years, depending on the condition.

9️⃣ Possible Side Effects

Mild redness, irritation, or temporary floaters.
Rare risks include infection, increased eye pressure, or retinal detachment.
