Your heart and kidneys are not the only organs that can become damaged by high blood pressure (hypertension). It can also damage the retina, the layer of tissue at the back of the eye that converts light and images entering the eye into nerve signals that are transmitted to the brain for interpretation. “Hypertensive retinopathy” is caused by high blood pressure that damages the blood vessels in the retina. The more pronounced the hypertension, and the longer that blood pressure has been high, the more severe the damage is likely to be. Symptoms include double vision, dim vision, or vision loss, which should be reported to the ophthalmologist, who can determine their causes.
P.S. Individuals who smoke, have diabetes, or have high cholesterol levels have a higher risk of retinal damage and vision loss.
