Corneal Arcus (arcus senilis)

Description of Corneal Arcus  (Arcus Senilis)

Corneal Arcus, sometimes referred to as Arcus Senilis in an older patient, is a greyish or yellowish opaque colored ring or arc around the peripheral cornea of both eyes.  The corneal arcus ring consists of lipid/cholesterol deposits in the periphery of the cornea stromal layer. The lipid deposits (corneal arcus) typically start at 6 & 12 o’ clock on the cornea, but can eventually fill in to create a full ring.
