Arcus senilis is most commonly observed in which population?

• A. Children
• B. Young adults
• C. Older adults
• D. Infants

Answer: (C)

Arcus senilis is a grayish-white ring around the cornea caused by lipid deposits in the peripheral cornea. It is most commonly observed in older adults because it reflects age-related changes in the eye’s tissues and lipid metabolism that accumulate over time. It usually appears in both eyes, does not affect vision, and is often considered a benign age-related change. In younger individuals, seeing this ring would raise consideration for lipid disorders, but among typical age groups, older adults are the group where this finding is most common.
