Complications after RVO can include macular edema, reduced retinal blood flow, abnormal new blood vessels, bleeding, and pressure-related problems in some eyes. Macular edema, which is swelling in the central retina, is one of the most common complications and a major reason vision becomes blurred after RVO. The type of RVO and how much retina is involved can influence which complications occur.
Macular edema after RVO
One of the most common complications is macular edema, which is swelling in the central retina. It is a major reason vision becomes blurred after RVO.
Reduced blood flow and new blood vessels
Some eyes develop more significant loss of retinal blood flow. In that setting, abnormal new blood vessels may grow, which can lead to bleeding or other problems.
Pressure-related complications
If abnormal new blood vessels affect the front part of the eye, eye pressure can rise. This is one reason some forms of RVO need careful follow-up.

Why complication patterns differ
The type of RVO, the amount of retina involved, and whether the eye is ischemic can all influence which complications occur.
Key takeaway
Complications after RVO can include macular edema, reduced retinal blood flow, abnormal new blood vessels, bleeding, and pressure-related problems in some eyes.

What is the most common complication of RVO?
One of the most common complications is macular edema, which is swelling in the central retina, and it is a major reason vision becomes blurred after RVO.
Why do new blood vessels matter after RVO?
Some eyes develop more significant loss of retinal blood flow, and in that setting abnormal new blood vessels may grow, which can lead to bleeding or other problems. If they affect the front part of the eye, eye pressure can rise.
Why do complications differ between patients with RVO?
The type of RVO, the amount of retina involved, and whether the eye is ischemic can all influence which complications occur.
