Intravitreal Injections
How are Intravitreal Injections administered?
This is a drug that can be injected into the vitreous (the jelly in the posterior part of the eye ) to treat wet macular degeneration or other causes of macula swelling such as diabetes and vein occlusions.
It works by blocking a substance called vascular endothelial growth factor which helps to prevent the growth of abnormal vessels in the retina and associated leakage.
Your Ophthalmologist will be able to go through the process of the injections in detail should you need this treatment.
The Procedure
Intravitreal injections are administered directly into the vitreous humor of the eye to treat various retinal conditions, including wet age-related macular degeneration (AMD), macular edema, and others.
Aftercare
After the treatment:
- Have someone drive you home
- Wear sunglasses if your eyes feel sensitive to light
- Try to rest your eyes as much as possible (for at least a few hours)

Frequently Asked Questions
Does the procedure take long?
The actual injection procedure is typically quick, often lasting only a few minutes. However, the preparation and aftercare may extend the total time of the appointment. It's crucial to have regular follow-ups with the ophthalmologist to monitor the condition being treated and to determine if and when further injections are needed.
Is the procedure painful?
The eye is numbed with an anesthetic before the injection, so pain is typically minimal. Some patients might feel slight pressure or discomfort.
Will my vision improve immediately?
Some patients may notice improvements soon after the injection, but for others, it might take a few days or even longer. The primary goal is often to halt disease progression.
Is the injection safe?
While all medical procedures carry some risks, intravitreal injections are generally considered safe when administered by trained professionals. The benefits often outweigh the potential risks, especially when treating severe retinal conditions.
