Intravitreal steroid injection is a procedure used to deliver steroid medications directly into the vitreous of the eye. This treatment is commonly used for conditions like diabetic macular edema, retinal vein occlusion, or uveitis, where inflammation causes swelling and vision loss in the retina.

Steroids injected into the eye work by reducing inflammation and swelling, promoting faster healing, and preventing further damage to the retina. The procedure is relatively quick, performed in an outpatient setting, and involves minimal discomfort.

Intravitreal steroid injections are often used when other treatments, such as oral medications or laser therapy, are ineffective. While the effects of the injection may last for several weeks or months, some patients may require repeat injections to maintain visual improvement.
