The “senilis” in the name is related to the word senile. These white rings around the iris are considered normal with age. When the deposits consist of calcium, the limbus appears milky and may indicate tissue damage that needs correction.

When corneal arcus occurs in those less than 40 years old, the name used for the condition is arcus juvenilis. The incidence is even higher in the African American population, although researchers aren’t sure why. For persons over the age of 80, corneal arcus afflicts nearly 100 percent of those tested. The condition affects about 60 percent of the population between 50 and 60 years old.
However, these deposits can eventually expand to completely cover the entire circumference of your cornea, which is usually when you start having vision problems. The phospholipid sediments of the corneal arcus generally start at the bottom and the top of your cornea. The material is made of an abnormally high level of phospholipids and cholesterol deposits. This opaque halo surrounding your cornea’s stromal layer has a distinct border on the outside while the inside border is less defined. A flaxen or gray-colored band forms, circling the cornea of each affected eye. Arcus senilis is a circular ring in the periphery of your cornea made up of cholesterol deposits.
