Arcus senilis is a white, gray, or blue arc or ring that develops around the edge of the cornea. It typically appears as an arc that affects the top and bottom of the cornea. Over time, the arcs can grow and connect, forming a complete ring.
Arcus senilis is also known as corneal arcus.
CAUSES AND RISKS FACTORS for ARCUS SENILIS
Arcus senilis most commonly appears as people age.
Arcus senilis occurs due to fat deposits, or lipids, forming in the outer part of the cornea. Fats in the blood come from fatty foods in a person’s diet. The liver also produces them.
Arcus senilis does not have any complications unless it is a sign of high cholesterol.
High levels of cholesterol in a person’s blood can cause significant problems, such as coronary artery disease or cardiovascular disease.
SYMPTOMS OF ARCUS SENILIS
A person with arcus senilis may notice a white, gray, or blue circle or arc around the cornea of the eye.
The circle or arc will have a sharp outer border but a blurred inner border. If someone has an arc, the lines could grow to form a complete circle in front of the iris.
People with arcus senilis are unlikely to have any other symptoms, and their vision will remain unaffected.
TREATMENT OF ARCUS SENILIS
Once it appears, it will not fade or disappear. However, treatment for arcus senilis is not necessary.
If arcus senilis is a sign of high cholesterol, a doctor may recommend a diet that is low in saturated fats and high in fruit, vegetables, and fiber. Increased exercise and quitting smoking can also help.
