MEfRVO is a serious eye condition that can quickly get worse or lead to a complete loss of vision.1,2 The good news is that treatment options are available, and you've taken steps to help manage your MEfRVO.3-6

What is MEfRVO?

MEfRVO occurs when a blood vessel in the retina becomes blocked by a blood clot (also called a retinal vein occlusion) and leaks fluid into the macula.7,8 Vision loss or blurring happens as the macula swells with the fluid.1,2 There are 2 types of MEfRVO: MEfBRVO and MEfCRVO.

What is Macular Edema following Central Retinal Vein Occlusion (MEfCRVO)?

MEfCRVO occurs when the central retinal vein becomes blocked by a blood clot.7 MEfCRVO occurs less often than Macular Edema following BRVO (MEfBRVO), making up 2 out of every 10 diagnosed cases of MEfRVO.9

What is Macular Edema following Branch Retinal Vein Occlusion (MEfBRVO)?

MEfBRVO occurs when one or more veins branching out from the central retinal vein become blocked by a blood clot.8 Most diagnoses (8 out of 10 cases) of MEfRVO are MEfBRVO.9

What can put you at risk for MEfRVO?5,6,10

  • Being 50 years of age or older
