Question

One of the possible complication if you have hypertension is eye damage, why? what's the relation of it? tnx

Answer 1

Because the blood vessels to the eyes are very thin and could not withstand prolonged pressure. They rapture and when that happens, the delivery of nutrients to the cells in the eyes fail causing the cells to die. This in turn causes vision to fail.

Answer 2

In hypertension, the heart has to work much harder to push a certain volume of blood through the body. Your thicker, more muscled blood vessels can handle this for a while, but the pressure is most destructive at the smallest blood vessels in your body (microvasculature). As these very fine capillaries, arterioles, and venules are damaged, they remodel and infarcts may develop, leading to nerve damage. The end result is a loss of working tissue or nerves, in places that have a lot of microvasculature: eyes, kidneys, periphery, etc.
