Intravitreal steroid injection involves placing a small dose of steroid medication directly into the vitreous cavity of the eye. It is used to treat inflammatory or fluid-related retinal conditions when longer-acting control is needed.
Why intravitreal steroid is used
Steroid injections or implants may be offered for uveitis, diabetic macular oedema or vein occlusions, especially when anti-VEGF drugs or drops alone are insufficient. They can provide prolonged reduction of inflammation and swelling but require monitoring for raised pressure and cataract.
- Performed with anaesthetic drops and antiseptic to reduce infection risk
- Some preparations are single injections, others are slow-release implants
- Follow-up checks look for pressure changes and response to treatment
- Additional injections may be required if the effect wears off
