Arcus senilis is a white or gray opaque ring or arc that develops around the cornea of the eye. The arc or ring with arcus senilis comes from lipids (fats) or cholesterol deposited in the cornea. Arcus senilis can become larger over time and may form a complete ring around the cornea.

Arcus senilis is not dangerous and it doesn't affect your vision. It usually occurs in people over the age of 50. It is considered a normal part of aging.

This article discusses arcus senilis, its causes, and if it requires treatment.

Symptoms of Arcus Senilis

If you develop arcus senilis, you may notice a white or gray half-circle on your eye. The arc can appear both in the upper and lower areas of your cornea, which is the normally clear, dome-like structure in the front part of the eye.

The half-circle will have a sharp outer border and a fuzzy inner border. The lines may eventually fill in to form a complete circle around your iris, the colored part of your eye.

With arcus senilis, you most likely won’t develop any other symptoms, and your vision shouldn’t be affected.

What Causes Arcus Senilis?

Arcus senilis is caused by fat deposits in the cornea. It is seen often in older people but is sometimes present at birth. For most people, arcus senilis is benign and will not affect vision.

When arcus senilis develops in early or middle life, it is referred to as arcus juveniles. The condition is concerning when it appears in younger people. Because arcus senilis consists of lipid deposits, if you have arcus senilis and you are younger than 40, it could represent high lipid blood levels, and, therefore, possibly high cholesterol.

The connection between arcus senilis and high cholesterol or atherosclerosis has been very controversial. As far back as 1852, German pathologist Rudolf Virchow discussed an association between corneal arcus and atherosclerosis. However, nearly 40 years later, physician William Osler suggested that arcus was not diagnostic for “fatty degeneration” of the heart.

Diagnosis

When healthcare providers perform an eye examination, many factors are taken into consideration before making an assessment. For example, when a healthcare provider sees arcus senilis in a younger person, they will pay particular attention to their findings in the retina.

During the examination, special eye drops will be instilled into the eye to dilate the pupil. When the eye is dilated, the retinal blood vessels are inspected for signs of disease. The blood vessel appearance and thickness can give clues to possible elevated lipid levels and atherosclerosis.

If there appears to be atherosclerosis of the retinal blood vessels, and the patient also happens to have arcus senilis, then it is more likely that they will recommend a visit to your healthcare provider, internist or cardiologist.

Arcus Senilis vs. Cataracts

Arcus senilis and cataracts are both conditions of the eye that develop with age. However, arcus senilis does not affect how well you can see, while cataracts can grow over time until they eventually cover the lens of your eyes and cause vision loss.

How Arcus Senilis Is Treated

Arcus senilis does not require treatment. However, your healthcare provider might recommend that you have your cholesterol levels checked, especially if you are under the age of 40, as you may be at higher risk for high cholesterol and coronary artery disease.

High cholesterol can be treated in several ways. Your healthcare provider may recommend lifestyle changes, such as exercising more and eating foods low in saturated fat, trans fat, and cholesterol.

As for the visible ring or arc in your eye, there is no way to remove it. Some have advocated eye tattooing to help cover it up. However, for the most part, this is not recommended in the medical community. 

Summary

Arcus senilis is a benign condition of the eye that causes an arc or ring to appear around the cornea. The condition is caused by lipid deposits. It does not affect vision.

In patients over 40 years of age, arcus senilis is most often a benign finding. In someone younger than 40, it could mean high cholesterol. Although arcus senilis itself does not require treatment, high cholesterol requires management. See your healthcare provider if you have arcus senilis and are under the age of 40.
