Intra Vitreal Injection into the Eye

Intravitreal injections of anti-VEGF medicine can be used to treat a number of eye conditions that cause bleeding or swelling (oedema) of your retina resulting in blurring or loss of vision. 

Eye conditions which can be treated include

How does the Treatment work?

Vascular endothelial growth factor (VEGF) is a protein produced by cells in the eye in certain conditions such as poorly controlled diabetes or vein occlusion and in ARMD.  The VEGF results in the growth of abnormal new blood vessels in the retina.  Unfortunately these vessels are leaky and causes bleeding or retina swelling which results in blurring or loss of vision.

Anti-VEGF medicine blocks these VEGF, thereby slowing the growth of new blood vessels in the eye. This will slow and stop the damage caused by these abnormal leaky blood vessels.

How is the Treatment given

Anti-VEGF treatment is given as an injection into your eye directly into the vitreous gel that fills your eye. The procedure is usually quick (between 5 to 15 minutes) and is not painful because you will be given an anaesthetic before hand.

Post-Treatment Care

Although there are no restrictions to working or exercise, do take it easy for the first few days.  You may be given eye drops to prevent infection and to reduce inflammation

If you have co-exisiting medical conditions such as hypertension, cholesterol or diabetes, do make the effort to keep these conditions under good control as this will help with the recovery process and also prevent future recurrences.


The visual recovery from the procedure varies from person to person and can take up to 1-2 months to see some improvement.  You may need regular injections which can vary between 1 to 3 monthly intervals for up to 1-2 years or more.  It is important to see your eye doctor regularly for the eye check and/or OCT retina scan to monitor the recovery progress.

Do check your vision regularly using the chart below to monitor your progress
