Overview
Arcus senilis is a white or gray opaque ring in the corneal margin peripheral (corneal) opacity, present at birth, or appearing later in life, and becoming quite frequent in those over 50; it results from cholesterol deposits in or hyalinosis of the corneal stroma and may be associated with ocular defects or with familial hyperlipidemia.
Pathophysiology
It can be a sign of disturbance in lipid metabolism, an indicator of conditions such as hypercholesterolemia, hyperlipoproteinemia or hyperlipidemia.
A unilateral arcus is a sign of carotid artery disease or ocular hypotony.
