Intravitreal & Subtenon Steroid Injections

Intravitreal & Subtenon Steroid Injections

Description:

Intravitreal and Subtenon steroid injections are medical treatments used to manage inflammatory and non-inflammatory conditions affecting the eye. Both approaches involve delivering steroid medications to control inflammation, reduce swelling, and alleviate symptoms in the eye.
Intravitreal Steroid Injections: These involve injecting steroids directly into the vitreous cavity, the gel-like substance inside the eye. This method provides high local concentrations of the steroid, targeting conditions such as diabetic macular edema, retinal vein occlusion, and uveitis.
Subtenon Steroid Injections: These involve injecting steroids into the space beneath the Tenon's capsule, a membrane that covers the eye. This method is often used for managing conditions like uveitis or severe conjunctival inflammation. The steroid is distributed around the eye, providing broader anti-inflammatory effects.

Blurred Vision: Difficulty seeing clearly or experiencing visual distortions.
Eye Pain or Discomfort: Mild to moderate pain or discomfort in the eye.
Floaters: Presence of small specks or spots in the vision.
