People with diabetes and high blood pressure are at an even greater risk for developing this condition. Managing blood pressure is also the only way to treat hypertensive retinopathy.
What is silver wiring in eyes?
Silver wiring or copper wiring is where the walls of the arterioles become thickened and sclerosed causing increased reflection of the light. Arteriovenous nipping is where the arterioles cause compression of the veins where they cross. This is again due to sclerosis and hardening of the arterioles.

Symptoms usually do not develop until late in the disease and include blurred vision or visual field defects.
Diagnosis of Hypertensive Retinopathy
Diagnosis is by history (duration and severity of hypertension) and funduscopy.
Treatment of Hypertensive Retinopathy
Hypertensive retinopathy is managed primarily by controlling hypertension. Other vision-threatening conditions should also be aggressively controlled.

Why is Copper Wire Going Black?
Copper is a versatile metal. Copper wire does not rust, but it will oxidize and tarnish over time. When it does, it usually turns a greenish color. This is called a patina (a great example is the statue of liberty). The patina is not generally damaging to the wire, and it should still function. However, over time copper can begin to erode – especially under certain situations. See the chart below to understand how various metals corrode.
