The causes of hypertension occurring are not related to the eyes, but hypertension has the potential to adversely affect the eyes. Hypertension is an increase in the pressure of blood vessels in the body, which is a systemic disease that affects all blood vessels throughout the body. If hypertension is chronic and the blood pressure is not well controlled, there is a tendency to develop fundus vasculopathy leading to retinal arteriosclerosis, proliferation and thickening, or arteriosclerosis leading to narrowing, which can then easily affect the patient’s vision. The cause of hypertension has nothing to do with the eyes. If the blood pressure is relatively high and the patient has clinical symptoms, most of them will not manifest as eye discomfort. Patients with hypertension will have dizziness and headache, but they will not usually affect their eyes, unless they are prone to affect their vision when hypertensive vasculopathy occurs.
