What’s my risk for RVO?

Know your risk factors for RVO (CRVO and BRVO)

Additional Risk Factors for CRVO:

To help control your high blood pressure, diabetes, arteriosclerosis and high cholesterol you should take your medications as directed, get 2.5 hours of moderate (heart pumping) exercise per week, eat a healthy diet and maintain a healthy weight. 7

If you are 40 years and under and develop RVO, your risk factors may be different. Visiting your PCP to have additional testing is important. 9

It is important for your PCP to know you have an RVO. Your PCP will check, monitor and treat high blood pressure, diabetes, arteriosclerosis, high cholesterol and sleep apnea.
