Treatment for Retinal Diseases
Intravitreal injections are a modern and effective therapeutic method used to treat serious retinal conditions, such as wet age-related macular degeneration (AMD), macular edema following retinal vein occlusion, diabetic macular edema, and other less common disorders. This treatment delivers medication directly into the vitreous cavity of the eye, providing targeted and immediate action.
Procedure for Intravitreal Injections
The procedure is performed under local anesthesia, ensuring that the patient feels no pain during the injection. It is carried out under sterile conditions in a surgical setting to minimize the risk of infection.
Using a fine needle, the ophthalmologist injects anti-VEGF medication or a steroid implant directly into the vitreous body, precisely at the site requiring treatment. The goal is to inhibit abnormal blood vessel growth (as in wet AMD) or to reduce inflammation and swelling in the macular tissue.
Benefits and Indications
Intravitreal injections are primarily used for:
- Wet age-related macular degeneration, where abnormal blood vessels grow under the retina
- Macular edema due to retinal vein occlusion
- Diabetic macular edema
Timely and appropriate treatment can help eliminate or reduce swelling, protect vision, and prevent permanent damage to the retina.
Additionally, these treatments help control inflammation and improve visual function, halting further vision deterioration.
Results and Safety
Intravitreal injections are generally safe and effective, with most patients experiencing significant improvement in their vision or symptoms. The procedure is minimally invasive, and side effects are rare—usually limited to mild pain or redness at the injection site.
In rare cases, intraocular infections (endophthalmitis) may occur, but these are typically prevented by strict adherence to sterilization protocols.
Intravitreal injection therapy offers a valuable treatment option for managing serious retinal conditions that affect the macula and retina, helping patients maintain or even improve their vision.
