Symptoms of retinal vein occlusion typically affect one eye and include:

  • Blurry vision or vision loss: This may start suddenly or develop gradually over a period of hours or days.
  • Floaters: These are dark spots or lines in your field of vision.
  • Pain or pressure in your eye: This is typically in more severe cases.

You may not have any symptoms until complications arise. Some people don’t realize there’s a problem until their provider finds the issue during a routine eye exam.
