Arcus Senilis
Arcus senilis (corneal arcus) is a bilateral condition manifesting as a white ring in the periphery of the cornea.[7] It is a lipid-rich corneal deposit that does not affect the patient's vision. It begins at the top and bottom of the cornea and spreads to form a complete ring. It is most commonly seen in elderly patients. Therefore, arcus senilis in patients below 50 years of age should be referred for a lipid profile, since it may indicate hyperlipidemia, hypercholesterolemia, or hyperlipoproteinemia.[8] However, the relationship between arcus senilis and cardiovascular disease is yet to be established.[9]
