Have you ever thought of why grandma or grandpa has a white ring around the periphery of his or her cornea?. The presentation is ARCUS SENILIS.

Arcus senilis is generally harmless, although it can sometimes be a sign of high cholesterol in people under 45 years of age.

Those affected by this eye condition will notice a half circle, full circle, or arc around the cornea of their eye. The cornea is the clear, dome-like front part of the eye.

The arc or circle is usually white, gray, or blue in color. It forms in front of the iris, which is the colored part of the eye.

Although the appearance of arcus senilis can be alarming, it is usually not considered to be a danger to a person's health or a sign that vision is deteriorating. It can be seen mostly in old people .In fact, nearly 100 percent of people over 80 years old will be affected. Around 60 percent of people over 60 years of age will also have this condition.
Arcus senilis occurs due to fat deposits, often referred to as lipids, forming in the outer part of the cornea. Fats in the blood come from fatty foods in a person's diet and are also produced by the liver.

Cholesterol is one type of fat that appears in the blood. However, the occurrence of arcus senilis does not necessarily mean that someone has high cholesterol.

The blood vessels in the eyes widen with age. As someone ages, their blood vessels allow more cholesterol and other fats to build up in the eye.

However,If arcus senilis appears in people under the age of 40 years old, doctors will carry out a test to check for high cholesterol; visiting a doctor will ensure that there are no hidden causes that could lead to further health complications if the eye change is left untreated.
