'''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'''.

| name            = Arcus senilis
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.

'''Arcus senilis''' is a common [[ophthalmological]] condition characterized by a gray or white arc or ring around the [[cornea]] of the eye. This condition is often associated with aging and is considered a normal finding in older adults. It is also known as corneal arcus or arcus lipoides.
==Pathophysiology==
Arcus senilis occurs due to the deposition of [[lipids]] in the peripheral cornea. These lipids are primarily cholesterol and phospholipids, which accumulate in the corneal stroma. The condition is typically bilateral, meaning it affects both eyes, and the arc or ring is usually located at the corneal periphery, sparing the central cornea.
==Clinical Presentation==

Arcus senilis appears as a white, gray, or blue opaque ring in the corneal margin. It is more common in older adults, typically appearing after the age of 50. In younger individuals, the presence of arcus senilis may indicate hyperlipidemia or other lipid metabolism disorders.
==Diagnosis==
The diagnosis of arcus senilis is primarily clinical, based on the characteristic appearance of the corneal ring. An [[ophthalmologist]] can easily identify the condition during a routine eye examination using a slit lamp.

Arcus senilis itself does not require treatment, as it does not affect vision or cause any symptoms. However, if it is associated with hyperlipidemia, managing the underlying lipid disorder is important to reduce cardiovascular risk.

Arcus Senilis[edit]

Corneal arcus

Arcus senilis is a common ophthalmological condition characterized by a gray or white arc or ring around the cornea of the eye. This condition is often associated with aging and is considered a normal finding in older adults. It is also known as corneal arcus or arcus lipoides.

Pathophysiology[edit]

Arcus senilis occurs due to the deposition of lipids in the peripheral cornea. These lipids are primarily cholesterol and phospholipids, which accumulate in the corneal stroma. The condition is typically bilateral, meaning it affects both eyes, and the arc or ring is usually located at the corneal periphery, sparing the central cornea.

Clinical Presentation[edit]

Arcus senilis appears as a white, gray, or blue opaque ring in the corneal margin. It is more common in older adults, typically appearing after the age of 50. In younger individuals, the presence of arcus senilis may indicate hyperlipidemia or other lipid metabolism disorders.

Diagnosis[edit]

The diagnosis of arcus senilis is primarily clinical, based on the characteristic appearance of the corneal ring. An ophthalmologist can easily identify the condition during a routine eye examination using a slit lamp.

Significance[edit]

While arcus senilis is generally considered a benign condition in the elderly, its presence in younger individuals may warrant further investigation for underlying lipid disorders. In such cases, a lipid profile test may be recommended to assess cholesterol levels and evaluate the risk of cardiovascular disease.

Management[edit]

Arcus senilis itself does not require treatment, as it does not affect vision or cause any symptoms. However, if it is associated with hyperlipidemia, managing the underlying lipid disorder is important to reduce cardiovascular risk.

Related Conditions[edit]

Arcus senilis should be differentiated from other corneal opacities and rings, such as Kayser-Fleischer ring, which is associated with Wilson's disease.
