Hypertensive retinopathy is a condition where high blood pressure harms the blood vessels in your eyes. Because many people have high blood pressure, understanding hypertensive retinopathy is important. When left unchecked, high blood pressure can cause eye complications that may lead to vision problems. For this reason, learning about the link between high blood pressure and your eyes can help you protect your sight.
What is Hypertensive Retinopathy?
Hypertensive retinopathy happens when the tiny blood vessels in the retina, which is the back part of your eye, become damaged due to high blood pressure. As a result, these vessels may become narrow, leak fluid, or even bleed. Over time, this damage can affect your vision. In the United States, many adults are at risk for hypertensive retinopathy because high blood pressure is common.
Symptoms of Hypertensive Retinopathy

Causes and Risk Factors
High blood pressure is the main cause of hypertensive retinopathy. Still, some factors can increase your risk, such as:
Additionally, people with other health problems like kidney disease face higher risks.
How High Blood Pressure Affects the Eyes
High blood pressure puts extra force on blood vessel walls. Over time, this pressure can make the vessels in your eyes stiff or narrow. Consequently, blood and oxygen have a harder time reaching the retina. Sometimes, the vessels may leak blood or fluid, causing swelling and retinal damage due to hypertension. In severe cases, this can lead to vision loss or even blindness.
Diagnosis of Hypertensive Retinopathy
Eye doctors use special tools to look at the back of your eye. During an eye exam, your doctor may use drops to widen your pupils. Then, they check for changes in your retinal blood vessels. Sometimes, they may take pictures of your retina or use other tests to see how much damage has occurred. Early diagnosis is key to protecting vision with high blood pressure.
Treatment Options
The main goal is to control your blood pressure. When you lower your blood pressure, you help prevent more damage. In some cases, your doctor may suggest:
