Intravitreal Injections

Intravitreal Injections

Introduction

Intravitreal injections are a revolutionary advancement in ophthalmology, offering an effective treatment for a range of retinal diseases. These injections deliver medications directly into the vitreous humor, the gel-like substance inside the eye, ensuring targeted treatment.

Patients seeking expert eye care can consult Dr. Shiva Prasad Kakarla, a leading Eye Doctor in Bangalore, for precise diagnosis and treatment. With access to state-of-the-art facilities at the Best Eye Hospital in Hosur Main Road, patients can receive high-quality care for various retinal conditions.

What Are Intravitreal Injections?

Intravitreal injections involve injecting medication into the vitreous cavity to treat retinal diseases. This procedure is commonly used to manage conditions such as:

• Age-related Macular Degeneration (AMD) – A progressive disease affecting central vision.
• Diabetic Retinopathy – A complication of diabetes that damages the blood vessels in the retina.
• Retinal Vein Occlusion (RVO) – A blockage in the retinal veins leading to vision impairment.
• Macular Edema – Swelling in the macula due to fluid leakage from damaged blood vessels.
• Endophthalmitis – A severe intraocular infection requiring immediate treatment.

For those seeking specialized care, Dr. Shiva Prasad Kakarla, an experienced Eye Specialist in Krishna Nagar Layout, offers expert evaluation and administration of intravitreal injections for retinal conditions.

Types of Medications Used in Intravitreal Injections

Intravitreal injections contain different medications, depending on the condition being treated. The most common drug categories include:

1. Anti-VEGF (Vascular Endothelial Growth Factor) Agents

These drugs help reduce abnormal blood vessel growth and leakage in the retina. Common anti-VEGF drugs include:

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

Anti-VEGF injections are widely used to treat AMD, diabetic retinopathy, and retinal vein occlusion.

2. Corticosteroids

Steroid injections help reduce inflammation and swelling in the retina. Commonly used steroids include:

• Dexamethasone Implant (Ozurdex)
• Triamcinolone Acetonide

These injections are particularly effective for macular edema associated with diabetic retinopathy and retinal vein occlusion.

3. Antibiotics and Antifungal Agents

In cases of severe intraocular infections like endophthalmitis, intravitreal injections containing antibiotics or antifungal medications help eliminate the infection quickly and effectively.

The Procedure: What to Expect

The administration of an intravitreal injection is a quick and relatively painless procedure. It is performed in a sterile environment to minimize the risk of infection. Here’s what to expect:

• Pre-Injection Preparation: The eye is numbed with anesthetic drops to ensure comfort during the procedure.
• Sterilization: The eye is cleaned with an antiseptic solution to prevent infections.
• Injection Process: A fine needle is used to deliver the medication into the vitreous cavity.
• Post-Injection Monitoring: Patients are observed for a short period to ensure there are no immediate complications.

The entire procedure takes only a few minutes, and patients can usually resume their daily activities with minimal restrictions.

Benefits of Intravitreal Injections

Intravitreal injections offer numerous advantages, including:

• Targeted Treatment: Direct delivery of medication to the retina ensures better absorption and effectiveness.
• Minimal Systemic Side Effects: Unlike oral or intravenous medications, intravitreal injections reduce the risk of systemic side effects.
• Improved Vision: Regular injections can stabilize or even improve vision in patients with retinal diseases.
• Non-Surgical Approach: Intravitreal injections provide an effective alternative to invasive surgical treatments.

Potential Risks and Side Effects

While intravitreal injections are generally safe, some risks include:

• Mild Irritation or Redness: Temporary discomfort at the injection site.
• Floaters: Small spots in vision that usually resolve on their own.
• Infection (Endophthalmitis): A rare but serious complication requiring immediate medical attention.
• Retinal Detachment or Hemorrhage: Very rare complications that may require further intervention.

If any unusual symptoms, such as severe pain, decreased vision, or excessive redness, occur after an injection, patients should seek immediate medical attention at the Best Eye Hospital in Hosur Main Road.

Post-Injection Care and Follow-Up

After receiving an intravitreal injection, patients should:

• Avoid rubbing the eye for at least 24 hours.
• Use prescribed eye drops if provided.
• Attend follow-up appointments for monitoring.
• Report any unusual symptoms to an Eye Specialist in Krishna Nagar Layout promptly.
