HYPERTENSIVE RETINOPATHY
Hypertensive retinopathy is caused by high blood pressure. It causes damage to the retina and retinal circulation. (i.e. Hypertension).
High blood pressure can damage the retina’s blood vessels over time, limiting its function and putting pressure on the optic nerve, resulting in visual issues.
The primary cause of Hypertensive Retinopathy is chronically high blood pressure, also known as hypertension. High blood pressure is a chronic condition in which the blood’s power against your arteries is excessive.
Hypertensive retinopathy is caused by changes in the retinal vasculature caused by elevated blood pressure.
The arteriolar tone is initially increased due to autoregulation in the body’s effort to reduce blood flow, causing the arterioles to narrow. Sclerotic arteries with thickened intima and media layers can develop over time. The blood-retina barrier can eventually be breached, resulting in exudates and ocular ischemia or hemorrhage.
RISK FACTORS
The length of high blood pressure is the main risk factor for arteriosclerotic hypertensive retinopathy. The degree of blood pressure increase above normal is the most critical risk factor for malignant hypertension. Some research suggests that ocular vascular caliber is influenced by genetics.
Risk factors for essential hypertension include:
high salt intake, obesity, Smoking, alcohol, family history, and stress.
SYMPTOMS
