Arcus senilis

Arcus senilis is a grayish or whitish arc or circle visible around the peripheral part of the cornea in older adults. Arcus senilis is caused by lipid deposits in the deep layer of the peripheral cornea and not necessarily associated with high blood cholesterol.

However, a similar discoloration in the eyes of younger adults (arcus juvenilis) is often associated with high blood cholesterol. Such a finding in younger individuals warrants further evaluation by a doctor.
