Intravitreal Injections

Intravitreal injections are a common treatment used to slow or prevent vision loss caused by conditions involving abnormal or leaking blood vessels in the retina. The most frequently used medications are anti‑VEGF drugs, which help reduce swelling, stop harmful vessel growth, and may sometimes improve vision.

How does it work?

The medication is delivered directly into the vitreous cavity of the eye to ensure the highest effect on the retina. The procedure is performed in a sterile environment. Your eye is dilated, numbed with anaesthetic drops, and cleaned before a small needle is used to administer the injection into the eye. Most patients feel pressure but not pain. Treatment is often required on an ongoing basis.

Treatment and Recovery

Intravitreal injections are used to treat macular degeneration, macular oedema, diabetic retinopathy, uveitis, and retinal vein occlusion. Side effects are uncommon but can include inflammation, floaters, bleeding, or infection. After treatment, avoid rubbing the eye and report any worsening symptoms promptly.

The frequency of injections varies depending on the condition and individual response to treatment. Some patients require monthly injections, while others may need them less frequently.

Types of Medications Used in Intravitreal Injections

Several types of medications may be used for intravitreal injections depending on the condition being treated. Anti-VEGF medications are commonly used to block abnormal blood vessel growth and leakage. Steroid injections may be recommended to reduce inflammation and swelling in the retina. The choice of medication is tailored to each patient’s condition and response to treatment.
