Hypertensive Retinopathy

Hypertensive Retinopathy is a condition that affects the blood vessels in the eyes due to high blood pressure. It involves damage to the small arteries and veins in the retina, which is the light-sensitive tissue at the back of the eye. This damage can cause changes in vision and may lead to vision loss if severe. The condition reflects the impact of high blood pressure on the body's circulatory system, particularly the delicate vessels in the eye. Early signs include blurred vision and sometimes headaches. Monitoring eye health is important because the retina can reveal the severity of hypertension and its effects on other organs.

Hypertensive Retinopathy is a microvascular complication characterized by structural and functional changes in the retinal arterioles caused by chronic or acute elevations in systemic blood pressure. The core pathology involves arteriolar narrowing, arteriovenous nicking, and damage to the retinal capillaries leading to exudates, hemorrhages, and in severe cases, optic disc edema. It is primarily caused by sustained hypertension that induces endothelial dysfunction, increased vascular permeability, and ischemic injury to retinal tissue. Clinically, it serves as a window to systemic vascular damage and is associated with increased risk of stroke, myocardial infarction, and renal disease. The severity of hypertensive retinopathy correlates with the degree and duration of hypertension and can be classified into mild, moderate, and malignant forms based on retinal findings.
