{{Infobox medical condition
Aortic valve repair is a surgical procedure aimed at correcting defects or malfunctions of the [[aortic valve]], which is one of the four main valves in the [[heart]]. This procedure is often performed to treat conditions such as [[aortic regurgitation]] or [[aortic stenosis]]. Unlike aortic valve replacement, which involves replacing the valve with a prosthetic one, aortic valve repair focuses on preserving the patient's native valve.

* Aortic regurgitation: A condition where the aortic valve does not close properly, allowing blood to flow backward into the [[left ventricle]].

=== Postoperative Care ===
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.

* Regular follow-up appointments to assess valve function and overall heart health.
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.

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]

Four representative slides of corneal arcus

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.
