Intravitreal injections

Frequently asked questions regarding intravitreal injections answered


Why do I need injections?

The aim of eye injections is to prevent, or possibly reverse vision loss caused by macular conditions such as age-related macular degeneration (AMD), cystoid macular oedema from retinal vein occlusions, and diabetic eye disease.


Why do I need regular injections?

To prevent swelling or bleeding of the macula, some conditions require injections at regular intervals in the long-term. It is important to continue having injections if the doctor has recommended them to prevent putting your sight at risk.


Why do I need an OCT scan before every injection?

Before every injection your vision and eye pressure are assessed in conjunction with an OCT scan. The OCT scan provides the doctor with an image of the retina and macula. This aids in comparison and monitoring of how your eye is responding to injections and to see if further injections are required.


How often do I need injections?

Depending on your condition and how your eye responds to injections, the doctor can either extend or shorten the period between injections.


Are injections very painful?

No. As your eye will be numb from anaesthetic drops, you will only feel slight discomfort or pressure.


What happens after an injection?

Slight grittiness is expected, and there may be some bleeding on the white of the eye. This is normal and resolves quickly. You may also see a bubble or floaters that disappear over a few weeks. It is recommended to use lubricating gel or drops after an injection to relieve the gritty sensation, ensuring that the tip of the eye drop bottle does not touch your eye. If you notice severe pain, worsening vision, flashes of light or a severe headache, contact the doctor as soon as possible.


How long does an injection take?

Although the injection itself is very quick, expect to be in the clinic for around an hour. Assessments are performed prior by the orthoptist and ophthalmologist. Additionally, dilating and numbing eye drops will be used and can take up to 30 minutes to take effect.


What do I need to do to prepare for an injection?

Do not apply makeup to your eyes the day of an injection and keep your face as clean as possible. Regular drops can be used as normal unless instructed otherwise by the doctor. You can eat and drink as normal before an injection. A driver is recommended to bring you to and from your appointment
