The pressure exerted by blood against the walls of our blood vessels is known as blood pressure. Higher than usual blood pressure can lead to severe health problems and complications such as stroke, heart disease and others.

Hypertension is the medical name for high blood pressure; it is a serious health problem globally and the causes of the disease are not exactly known but are usually identified as the effects of an underlying health problem or a condition like kidney disease.

In this blog, we’ll take a look at how high blood pressure can lead to problems for our vision too in the form of hypertension retinopathy.

What is Hypertension Retinopathy?

Hypertension Retinopathy is an eye condition that is caused due to hypertension. When hypertension is left untreated for too long, it can start causing damage to the retina, which is the tissue at the end of our eye which plays a vital role in our eyesight and vision.

The condition occurs when the blood vessels that supply blood to the retina get damaged due to high blood pressure.

The chance of the retina being damaged by hypertension retinopathy increases with time if hypertension is left unchecked.
