What are intravitreal injections?
They're a way of treating conditions at the back of the eye by placing medicine directly into the vitreous, the clear gel inside your eye. The two main types are:
- Anti-VEGF injections, which reduce leakage and abnormal blood vessel growth
- Steroid implants, which slowly release medicine to reduce swelling
Which conditions are they used for?
- Wet age-related macular degeneration
- Diabetic eye disease, including swelling at the macula
- Retinal vein occlusion
What happens during treatment?
Your eye is numbed with anaesthetic drops and cleaned with antiseptic. A small device gently holds your eyelids open, and the injection itself takes only a few moments. Most people feel some pressure rather than pain. You go home the same day, but please don't plan to drive.
Afterwards
It's common for your eye to feel gritty or sore for a day or two, and you may see a small red patch on the white of your eye or floating spots. These usually settle. Paracetamol can help with any discomfort.
Risks
Serious complications are rare. The main one is a serious infection inside the eye, which happens in roughly 1 in 1,000 injections. Mrs Mann will explain the risks and benefits for you before you decide on treatment.
After an injection, seek help immediately if your eye becomes increasingly painful, red or sensitive to light, if it develops a discharge, if your vision gets worse, or if you see a curtain or veil across your vision.
Your consultation
Mrs Mann sees private patients at The London Medical Clinic in Marylebone, central London. A first consultation usually includes a discussion of your symptoms and medical history, a vision check, drops to widen your pupils, and an examination of the back of your eye. You may also have a retinal scan. The drops can blur your vision for a few hours, so please don't plan to drive afterwards.
Common questions
Do eye injections hurt?
Your eye is numbed first, so most people feel pressure rather than pain. Your eye may feel gritty or sore for a day or two afterwards.
How often will I need injections?
It depends on your condition and how your eye responds. Injections are often given more frequently at first, then spaced out.
Can I drive home after an injection?
Please arrange another way to get home, as your vision may be blurred afterwards.
Sudden change in your vision? Please don't wait for an appointment. Contact NHS 111 or go to your nearest A&E or urgent eye service.
