The human body needs cholesterol to function. This component of the outer coat of all cells helps with digestion and production of certain vitamins and hormones. Cholesterol is divided into two main types. LDL, which stands for low-density lipoproteins, consists mostly of fats and is known as 'bad' cholesterol. HDL, or high-density lipoproteins, are mostly made of proteins and are referred to as 'good' cholesterol.
Too much LDL can cause blockages in the arteries and raise the risk for heart attacks. Corneal arcus can be an indicator of high blood cholesterol. Cholesterol rings are fairly common with aging. In older adults, this ring is known as arcus senilis.
Cholesterol rings seen in people older than 50 are generally not considered a cause for concern because they often occur with normal aging. According to the 'Textbook of Ophthalmology,' 60 percent of people ages 40 to 60 have arcus senilis, and almost everyone over age 80 has this condition. While cholesterol rings can be prominent enough to be seen with the naked eye, they don't interfere with vision.
