Retinal Vein Occlusion (RVO)

Retinal Vein Occlusion (RVO)

Retinal vein occlusion occurs when a small vein in the retina becomes blocked, often due to a blood clot. This leads to a buildup of pressure and fluid, which can damage the retina and affect your vision.

Risk factors include:

  • Age (more common over 60)

  • High blood pressure

  • Diabetes

  • Glaucoma

  • Smoking

Symptoms may include sudden or gradual vision loss, blurring, or dark spots in your vision. Prompt evaluation is essential to manage complications and preserve vision.

Treatments

Anti-VEGF Injections: These medications help reduce swelling in the retina and improve vision. They are commonly used for macular edema caused by RVO.

Steroid Injections or Implants: Used to control inflammation and retinal swelling.

Laser Therapy: In some cases, laser treatment may be used to prevent or treat abnormal blood vessel growth or reduce retinal swelling.

Managing Underlying Conditions: Controlling high blood pressure, diabetes, and cholesterol is essential to reduce the risk of further damage or recurrence.
