Retinal Vein Occlusion


Our retina is a thin layer of tissue that lines the back of our eyeball. It turns light into signals to the brain, which interprets them as sight. When there is a blockage in one of the veins returning blood from your retina back to your heart, it’s called Retinal vein occlusion. Sometimes referred to as an eye stroke, retinal vein occlusion is one of the most common causes of vision loss worldwide. Specifically, it is the second most common cause of blindness from retinal vascular disease.

Blockages from blood clots impair your retina’s ability to filter light and your visual ability. The severity of loss of vision depends on which vein is blocked. At the ophthalmology department of AakashHealthcare Super Specialty Hospital, one can be rest assured of receiving the best possible treatment of such eye diseases. With state-of-the-art infrastructure, path breaking technology and unrivalled healthcare services, AakashHealthcare is on its way of becoming the most preferred healthcare brand by providing compassionate, inexpensive, and world class healthcare services, with a talented team of doctors, and ultra-modern technology, ensuring speedy recovery.

There are two types of retinal veins, one central vein and many smaller branch veins. Likewise, there are two types of retinal vein occlusion. First, central retinal vein occlusion and second, branch retinal vein occlusion.

Some frequently asked questions:

What are the symptoms of Retinal vein occlusion?

You may not always know that you’re going to have retinal vein occlusion. Almost always, it happens in only one eye. Some people, especially those with blockage in smaller blood vessels have no symptoms. The main symptom of retinal vein occlusion is a blurring or loss of vision that’s usually sudden. If not treated properly, the blurring or loss of vision usually gets worse in few hours or days. Sometimes, you’ll see dark spots or floaters, which are tiny clumps of cells floating in your eye. In severe cases, a blocked vein will build up pressure and cause pain in your eye.

How is retinal vein occlusion caused?

Retinal vein occlusions usually occur because your arteries harden and cause a clot, much like a stroke. Blockages are more common in people with narrowed or damaged blood vessels, or those with chronic conditions that cause them. Some of these diseases are mentioned below.

  • Hypertension
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Blood disorders that affect clotting
  • People over the age of 60
  • People who smoke
  • Glaucoma, which is optic nerve damage that’s usually caused by increased pressure
  • Hardened arteries, called atherosclerosis.

How is retinal vein occlusion treated?

The blockages in one’s retinal veins cannot be removed. So, the treatment focuses on problems arising from the occlusion, like:

  • Laser therapy to reduce edema, or swelling caused by fluid leakage
  • Drug injections of corticosteroids to reduce inflammation
  • Avitrectomy, which is the removal of all or part of the jelly-like tissue in your eye called the “vitreous humor”

What can one expect after the treatment?

The result of the treatment depends on the severity of the condition. Many people will recover and regain most of their vision, however for some, vision may not return.Those with other eye conditions or complications are less likely to recover fully.

Are there any complications involved in the treatment?

Complications associated with this treatment include infection, bleeding, retinal detachment, cataract, and both infectious and sterile uveitis; however, these complications remain relatively rare.
