Hypertensive Retinopathy - Eye Disorders - Merck Manual …
Hypertensive retinopathy is retinal vascular damage caused by hypertension. Signs usually develop late in the disease. Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema.
Hypertensive Retinopathy - EyeWiki
Long-standing hypertension can produce arteriolar sclerotic vascular changes, such as copper or silver wiring of the arterioles, as shown by the two arrows on the right, or arteriovenous nicking. Another sign of chronic hypertension is lipid exudates resulting from abnormal vascular permeability, as shown by the arrow at left.

2023年7月4日 · The signs are AV nicking, focal arteriolar narrowing (as this is associated with arteriosclerosis), microaneurysms, cotton wool spots, retinal hemorrhages (dot blot and flame-shaped), and decreased AV ratio.
Arteriovenous nicking - Wikipedia
This is most commonly seen in eye disease caused by high blood pressure (hypertensive retinopathy). It is thought that, since the arteriole and venule share a common sheath, the arteriole's thicker walls push against those of the venule forcing the venule to collapse. This makes the venule form an hourglass shape around the arteriole.
A Review of Hypertensive Retinopathy and Chorioretinopathy
Signs of mild hypertensive retinopathy, including generalized and focal arteriolar narrowing, copper wiring, and AV nicking, have been associated with coronary artery disease, 14 stroke, 15 and renal dysfunction. 16 The Ibaraki Prefectural Health Study found that mild hypertensive retinopathy was a risk factor for cardiovascular mortality ...

2023年11月29日 · This is called arteriovenous, or AV, nicking. Grade 3 has the signs of grade 2, but there’s also retinal edema, microaneurysms, cotton-wool spots (fluffy white lesions on the retina), and ...

Signs include arteriolar narrowing (with decreased size relative to corresponding venules), arteriovenous (AV) nicking (where arterioles cross venules), arteriolar sclerosis (with the appearance of copper wiring), flame hemorrhages, and cotton wool spots. Many of these findings are visible in Figure 1.
Hypertensive retinopathy - Wikipedia
Manifestations of these changes include Copper wire arterioles where the central light reflex occupies most of the width of the arteriole and Silver wire arterioles where the central light reflex occupies all of the width of the arteriole, and "arterio-venular (AV) nicking" or "AV nipping", due to venous constriction and banking.

2004年11月25日 · On the basis of the JNC criteria, the presence of retinopathy may be an indication for initiating antihypertensive treatment, even in people with stage 1 hypertension (blood pressure, 140 to...
Hypertensive retinopathy – Retinography
Arteriovenous (AV) crossing changes, also known as AV nicking, occur when thickened arterioles compress venules at crossing points, leading to venous constriction and potential vascular occlusion. Acquired Vitelliform Lesions (AVL) are characterized by subretinal yellowish deposits and can be assessed using fundus autofluorescence (FAF).
