The signs of chronic arterial hypertension in the retina include widening of the arteriole reflex, arteriovenous crossing signs, and copper (Figure 1 & 3) or silver wire arterioles (copper or silver colored arteriole light reflex). Malignant hypertension can also cause choroidopathy.
How does it appear? Retinal arterioles appear orange or yellow instead of red ("copper wiring. Retinal arterioles look white if they have become occluded ("silver wiring.
15 sty 2017 · Observable changes in retinal vascular architecture, such as increased retinal vein caliber (decreased artery-to-vein ratio), retinal vascular tortuosity, increased prominence of the retinal arterial reflex, venous nicking, “copper” or “silver wire” appearance as well as the discovery of cholesterol, calcium or thrombotic emboli are all ...
12 sie 2013 · Retinal signs of vascular pathology include an increased light reflex of the retinal arterioles (copper wiring or silver wiring, thought to occur as a result of atherosclerotic vessel wall thickening) and other arteriolar changes, including focal arteriolar narrowing, arteriovenous nicking, and microaneurysms.
Hypertensive Retinopathy (Copper Wiring) This image shows retinal arteriolar narrowing due to thickening and opacification of arteriolar walls (copper wiring) caused by hypertensive arteriosclerosis. ... read more
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.
1 lis 2013 · These permanent changes cause opacification of the arteriolar wall, sometimes known as “silver” or “copper” wiring, with consequent compression of venules due to atherosclerotic arteriolar changes, leading to arteriovenous nicking (AVN) 11 (Figure 1).
