Arcus senilis most commonly appears in which age group?

• A. Children
• B. Young adults
• C. People over 50
• D. Infants

Answer: (C)

Arcus senilis is a gray-white ring around the corneal margin caused by lipid deposits in the corneal stroma, and it tends to be an age-related, benign finding. It is most commonly seen in people over 50, reflecting normal aging of the eye rather than a primary pathology. It typically does not affect vision. If arcus appears earlier in life, it can prompt evaluation for lipid disorders, but in the typical older population it’s simply a common aging change.
