Arcus senilis

Arcus senilis is a medical condition characterized by a grey or white arc visible above and below the outer part of the cornea - the clear, dome-shaped surface that covers the front of the eye. This condition is common in older adults. It's also known as gerontoxon.

Causes

Arcus senilis is caused by fat (lipid) deposits in the edge of the cornea. It's often associated with high cholesterol levels and triglyceride levels in the blood, which is a condition known as hyperlipidemia. However, it can also occur in people who have normal cholesterol levels. The exact reason why these deposits form is not known.

Symptoms

Arcus senilis itself does not cause any symptoms. However, because it's often associated with high cholesterol levels, people with this condition may have symptoms of cardiovascular disease, such as chest pain (angina), heart attacks, and strokes.

Diagnosis

Arcus senilis is usually diagnosed during a routine eye examination. The doctor may notice the characteristic arc around the cornea. If arcus senilis is found, the doctor may recommend blood tests to check for high cholesterol levels.

Treatment

There is no specific treatment for arcus senilis. The condition itself does not affect vision and does not require treatment. However, because arcus senilis can be a sign of high cholesterol levels, it may be necessary to treat the underlying condition. This can involve lifestyle changes, such as eating a healthy diet and exercising regularly, and medication to lower cholesterol levels.

Prognosis

Arcus senilis is a benign condition that does not affect vision. However, it can be a sign of high cholesterol levels, which can increase the risk of cardiovascular disease. Therefore, it's important for people with this condition to have their cholesterol levels checked and managed.
