Which condition is associated with the finding of AV nicking during an examination?

The presence of AV nicking during a fundoscopic examination is predominantly associated with hypertension. AV nicking refers to the appearance of the blood vessels in the eye, where one vascular structure crosses over another, resulting in a nick or indentation due to the thickening and rigidity of the surrounding tissue, often caused by elevated blood pressure. This physical change occurs as a result of the chronic effects of hypertension on the vascular system, leading to changes in the retina's blood vessels like narrowing, nicking, or even hemorrhages.

In patients with uncontrolled or longstanding hypertension, the retinal changes can serve as indicators of systemic vascular health, and the identification of AV nicking can help healthcare providers assess the severity of hypertension and guide management. It showcases the impact of high blood pressure on the microvasculature, which is why this finding is significant in the context of hypertension.
