Retinal vein occlusion (RVO) is a disease that affects the retina, the part of the eye that is responsible for sharp, straight ahead vision. There are two types of RVO, which can lead to severe and sudden vision loss.1,2
Types of RVO
There are two types of RVO: Central RVO (CRVO) and Branch RVO (BRVO)
CRVO occurs when the eye’s central retinal vein becomes blocked1
BRVO occurs when branches of the eye’s retinal vein become blocked2
How Many People Have RVO?
1.1+ million Americans are affected by RVO.3 It is the second most common cause of vision loss due to retinal vascular disease3
How Does RVO Affect Your Eye?1,2
Fluid leakage and swelling into the retina can lead to a rapid and sudden loss of vision
Veins in the retina become blocked, restricting normal blood flow
Blocked veins can cause bleeding, fluid leakage and swelling into the retina
Signs and Symptoms1,2
Sudden blurring or vision loss in part of or all of one eye
Temporary loss of central vision
Central and peripheral visual disturbances
Floaters – dark spots or squiggles in central vision
RVO Risk Factors1,2
Age – people 50 or older
High blood pressure
Hardening of the arteries (arteriosclerosis)
Annual Dilated Eye Exam
Visit an eye doctor for a dilated eye exam. It’s the best way to detect changes in vision.
