High Blood Pressure Can Damage Your Eyes
Although high blood pressure rarely has symptoms, it can cause symptoms indirectly if it leads to complications. One complication of hypertension is hypertensive retinopathy, which results from damage to the blood vessels in the eyes. Your eyes are full of blood vessels that carry blood and oxygen. High blood pressure can decrease the amount of blood that reaches the retina in the back of the eye. The retina is responsible for capturing light as it enters the eye and processing it into visual images. This reduction in blood flow can result in blurry or distorted vision. In severe cases, hypertensive retinopathy leads to total loss of vision. Managing blood pressure can slow and even reverse the effects of hypertensive retinopathy. Chronic high blood pressure can also damage the optic nerve, which carries signals between the eyes and the brain. Optic nerve damage can cause temporary or permanent blindness.
