What leads to hypertensive retinopathy?

Hypertensive retinopathy is primarily caused by systemic hypertension, which leads to damage in the blood vessels of the retina. When blood pressure is consistently elevated, it can result in a range of pathological changes in the retinal vasculature. These changes include narrowing of the blood vessels, increased permeability, and even formation of exudates or hemorrhages due to vascular leakage. Over time, these changes can impair the retina's normal functioning and potentially lead to vision loss if not managed appropriately.

The relationship between systemic hypertension and retinopathy is well-documented, as the increased pressure causes stress on the endothelial cells of blood vessels, promoting an inflammatory response and structural changes that impair blood flow and nutrient delivery to the retinal cells. This condition is particularly relevant in individuals with chronic hypertension and can serve as an indication for further cardiovascular evaluation. Monitoring retinal health through regular ophthalmologic exams is important in hypertensive patients to prevent more severe complications.
