HOW DOES HIGH BLOOD PRESSURE EFFECT YOUR EYES?
An eye examination may be the first occasion that high blood pressure is suspected. With our opthalmoscopes, digital retinal cameras and other equipment, we may detect the first signs of a problem. We can see "nipping" of one blood vessel as it crosses another, or spot haemorrhages on the retina.
In extreme high blood pressure the sight may be threatened as there may be swelling at the optic nerve at the back of the eye and haemorrhages over the retina. There may also be an "occlusion" or blockage of the central retinal artery or vein, the main blood vessels in and out of the retina, with devastating results to the retina- but don't worry, these events are rare and if you stay healthy and keep your blood pressure under control, they are unlikely to happen.
