Retinal Vein Occlusion (RVO)

About Retinal Vein Occlusion

Retinal Vein Occlusion (RVO) occurs when a vein in the retina is blocked. The retina is the light-sensitive tissue at the back of the eye. This blockage can cause blood and fluid to leak into the retina, leading to swelling (macular edema), which can cause blurred vision or sudden vision loss.

Types of RVO:

  • Branch Retinal Vein Occlusion (BRVO): Blockage in one of the smaller branch veins.
  • Central Retinal Vein Occlusion (CRVO): Blockage of the main retinal vein.

Causes and Risk Factors

RVO is most common in people over 50 and is often associated with systemic health conditions like high blood pressure, diabetes, and high cholesterol.

Treatment

While there is no cure for RVO, treatment can help manage the condition and improve vision. The main goal is to treat the macular edema. Key treatments include:

  • Intravitreal Injections: Anti-VEGF medications are injected into the eye to reduce swelling and prevent the growth of abnormal blood vessels.
  • Laser Therapy: A focal laser can be used to seal leaking blood vessels.

Prompt treatment is required to prevent complications and preserve vision.
