Eye injections – also called intravitreal injections or IVI – are given to treat some macular conditions that cause abnormal blood vessel growth underneath the macula.
These new abnormal blood vessels are fragile and can leak fluid and blood, which may damage the macula.
This treatment involves an injection of medication into the clear, jelly-like substance inside the eye.
It may sound unpleasant but the injections should be painless and early action is crucial to saving your sight.
