Retinal vein occlusion (RVO) is an eye condition that commonly affects people over the age of 60. It happens when there is a blockage in a vein supplying a part of the eye called the retina. This causes a sudden, painless loss of vision.1

There are two types of RVO, depending on which vein is affected: branch RVO and central RVO. Generally, central RVO causes more severe vision loss.2

The exact cause of RVO is unknown, but there are a number of factors that make the condition more likely. These include1:

  • High blood pressure
  • High cholesterol
  • Glaucoma
  • Diabetes
  • Smoking
  • Certain rare blood disorders

It’s important to detect RVO as early as possible so the appropriate treatment can be started. You should tell your doctor immediately if you notice any changes in your vision.
