When it comes to protecting your vision, intravitreal injections have become a critical treatment for various retinal conditions such as age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusion. While these injections are highly effective, they can also raise many questions for patients. In this blog, we address the most common concerns to help you feel informed and confident.

1. What Are Intravitreal Injections?

Intravitreal injections deliver medication directly into the eye’s vitreous, the gel-like substance in the center of the eye. This targeted delivery allows the medication to act precisely where it’s needed, combating inflammation, abnormal blood vessel growth, or other retinal issues.

2. What Conditions Are Treated with Intravitreal Injections?

These injections are commonly used to manage:

• Wet Age-Related Macular Degeneration (AMD)
• Diabetic Retinopathy and Diabetic Macular Edema
• Retinal Vein Occlusion
• Uveitis
• Endophthalmitis
  Your doctor will determine if this treatment is appropriate based on your specific condition.

3. Is the Procedure Painful?

Patients often worry about pain, but the procedure is typically well-tolerated. Before the injection, your eye will be numbed with anesthetic drops or gel, minimizing discomfort. You might feel slight pressure or a mild pinch, but most patients report that the procedure is quick and relatively painless.

4. How Long Does the Procedure Take?

The actual injection takes only a few seconds, but the entire process, including preparation and aftercare, usually lasts about 15–20 minutes.

5. What Medications Are Used in Intravitreal Injections?

Common medications include:

• Anti-VEGF Drugs: Avastin, Lucentis, and Eylea, which target abnormal blood vessel growth.
• Steroids: Such as Ozurdex, for inflammation-related conditions.
• Antibiotics or Antifungals: For infections like endophthalmitis.

Your doctor will choose the medication based on your diagnosis and treatment goals.

6. Are Intravitreal Injections Safe?

Yes, intravitreal injections are considered a safe and effective treatment. However, like any medical procedure, they come with risks. Rare complications include:

• Infection (Endophthalmitis)
• Retinal Detachment
• Increased Eye Pressure
  Your doctor will take all necessary precautions to minimize these risks.

7. How Often Will I Need Injections?

The frequency depends on your condition and response to treatment. For example, wet AMD patients may require monthly injections initially, which can often be reduced over time. Your doctor will monitor your progress and adjust the treatment plan accordingly.

8. What Should I Do to Prepare for the Injection?

To prepare:

• Avoid makeup or lotions around your eyes on the day of the procedure.
• Inform your doctor of any medications you are taking.
• Arrange for someone to drive you home if your vision might be temporarily affected.

9. What Can I Expect After the Procedure?

After the injection, you may experience mild redness, irritation, or a feeling of grittiness in your eye. These side effects typically resolve within a day or two. Rarely, you might notice floaters or blurred vision. Contact your doctor immediately if you experience severe pain, vision loss, or unusual discharge.

10. Can Intravitreal Injections Improve My Vision?

For many patients, intravitreal injections can prevent further vision loss and, in some cases, significantly improve vision. The effectiveness depends on the underlying condition and how early treatment begins. Regular follow-ups are essential to achieving the best results.
