The cause of blurry eyes due to high blood pressure is usually a fundus lesion caused by hypertensive disease, which usually needs to be treated by lowering blood pressure reasonably, and there is no fastest way. Hypertension is the most common chronic disease, early may be asymptomatic or symptoms are not obvious, commonly dizziness, headache and other symptoms. With the prolongation of the disease, the blood pressure obviously continues to rise, and gradually a variety of symptoms will appear. If the long-term blood pressure is not well controlled, it can cause fundopathy such as small arteriosclerosis of the retinal arteries in the fundus vasculature of the eye, retinal hemorrhage and exudation, which can result in blurred vision. The treatment is to assess the patient’s condition and treat a reasonable antihypertensive program with specific conditions, so that the blood pressure control is up to the standard and the progression of fundopathy can be slowed down. Hypertensive emergencies occur when blood pressure rises suddenly and dramatically (usually over 180/120 mmHg), and can result in fundus changes: blurred vision, loss of vision, retinal hemorrhages, exudates, and optic papillae edema on fundus examination. Hypertensive emergencies cannot be rapidly lowered without causing a decrease in tissue perfusion pressure and inducing ischemic events. Therefore, the initial goal of blood pressure lowering is not to normalize the blood pressure, but to gradually lower the blood pressure to a safe level to prevent or reduce the damage to target organs such as the heart, brain, kidney, and eye to the maximum extent possible. When blurred vision occurs in hypertensive patients, it is recommended that the patient consult a doctor in a timely manner, complete relevant examinations, rule out cataracts and other non-hypertensive complications, and adjust the treatment program under the guidance of a physician if necessary.
