Understanding Retinal Vein Occlusion (RVO):

RVO is a blockage of a vein in the retina, the light-sensitive tissue at the back of the eye. This blockage disrupts blood flow and can lead to various vision problems, ranging from mild blurriness to severe vision loss. Two main types of RVO exist:

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

Symptoms of RVO:

• Sudden vision loss, often painless, in one eye.
• Blurred vision.
• Floaters, dark spots in your vision.
• Curtain-like shadow over part of your vision.
• Redness in the white part of your eye.

Seeking Medical Attention:

If you experience any of these symptoms, seek immediate medical attention from an ophthalmologist, particularly a retina specialist. Early diagnosis and treatment are crucial to minimize vision loss.

Treatment Options:

While no cure exists for RVO itself, treatments aim to address the complications and preserve vision. These include:

• Anti-VEGF injections: Medications injected into the eye to reduce abnormal blood vessel growth and swelling.
• Steroid injections or implants: To decrease inflammation and swelling.
• Laser treatments: To seal leaking blood vessels and prevent new ones from forming.
• Vitrectomy surgery: Removes blood from the vitreous gel in the eye in severe cases.
