Targeted Treatments for Various Eye Conditions
Understanding Intravitreal Injections and Their Benefits
An intravitreal injection is a procedure where medication is administered directly into the vitreous cavity of the eye. The vitreous cavity is the space between the lens and the retina filled with a gel-like substance called the vitreous humor. This method allows for targeted delivery of medication from board-certified ophthalmologists from RVSU. Intravitreal injections ensure a higher concentration of medication reaches the affected area at the back of the eye.Age-related macular degeneration (AMD) is the primary cause of vision loss in individuals over 50 in developed nations like the United States. Early detection and treatment are vital, as delayed diagnosis can significantly impact visual function. AMD has two forms: dry and wet.
Why You Might Need an Intravitreal Injection
Your ophthalmologist may recommend this procedure if you have conditions such as:
- Age-related Macular Degeneration (AMD): A leading cause of vision loss in people over 50, injections can help slow the progression of the disease and preserve vision.
- Diabetic Retinopathy: A complication of diabetes that affects blood vessels in the retina. Injections can reduce swelling and prevent further damage.
- Retinal Vein Occlusion (RVO): A blockage in the veins that drain blood from the retina. Injections can help reduce macular edema (swelling) and improve vision.
- Uveitis: Inflammation of the uvea, the middle layer of the eye. Injections can reduce inflammation and prevent complications.
- Endophthalmitis: A serious eye infection that can threaten vision. Injections deliver antibiotics directly to the infection site.
- Cystoid Macular Edema (CME): Swelling of the macula, which is part of the retina. Targeted injections can reduce swelling and symptoms such as blurry or wavy vision.
How Long Does Treatment Last?
When you receive intravitreal injections to treat various eye conditions, results can last a few months. At your consultation, we’ll discuss your options and the estimated time you’ll need between injections.
Preparing for Your Intravitreal Injection
Your ophthalmologist will provide specific instructions, but generally, you can expect the following:
- Discuss your medical history: Inform your doctor about any medications or allergies you have.
- Eye drops: You may be prescribed eye drops to use before the procedure.
- Fasting: In some cases, you may be asked to avoid food or drink for a certain period before the injection.
- Arrange for transportation: As your vision may be temporarily blurred after the procedure, arrange for someone to drive you home.
Post-Injection Care
After the injection, you may experience some mild discomfort, such as blurry vision, redness, or a feeling of grittiness. These usually subside within a day or two. Your doctor may prescribe eye drops to prevent infection and inflammation. Additional post-injection care includes refraining from wearing makeup or contact lenses for 1 – 2 days. It is crucial to follow your doctor’s instructions carefully and attend all follow-up appointments.
