What is the relationship between high blood pressure and eye sight?

High pressure is bad: Chronic hypertension increases the risk of atherosclerosis and blockages of the retinal vessels. Acute rises in pressure can cause a retinopathy and decreased vision. The eyes are only one place where high blood pressure attacks - this process is happening throughout the body. Best to take care of it!

Severe hypertension: Can cause hypertensive retinopathy (bleeding in blood vessels in the retina). It's also a risk factor for vascular occlusions, aneurysms, and other events that can decrease vision.
