Hypertensive retinopathy causes retinal blood vessels to thicken. Your retina is located at the rear of your eye and plays a vital role in the transferring of light to your brain for the processing of images. When you develop hypertensive retinopathy, the blood supply to your retina becomes restricted, and this causes swelling and puts too much pressure on your optical nerve. The condition is caused by high blood pressure, which can occur due to being overweight, consuming too much salt and being exposed to high levels of stress.
