The American Heart Association has identified both controllable and noncontrollable risk factors for high blood pressure. These factors are discussed in detail in the high blood pressure article. Effective treatment of high blood pressure will lower a person's risk for hypertensive retinopathy.
If the high blood pressure causing the retinopathy is not treated successfully, the person may lose part or all of his or her vision.
Hypertensive retinopathy is not contagious and poses no risk to others.
