A gray ring at the edge of the cornea (arcus senilis) is most commonly associated with which underlying issue that should be checked?

• A. Check lipid levels
• B. Evaluate for glaucoma
• C. Evaluate for cataracts
• D. Screen for retinopathy

Answer: (A)

Arcus senilis is a gray-white corneal ring caused by lipid deposition in the corneal stroma. While common with aging, when this finding appears in younger patients it points to possible hyperlipidemia, including high cholesterol or LDL, and signals cardiovascular risk. Therefore, the underlying issue to check is lipid levels with a lipid panel (and consider evaluating for familial hypercholesterolemia if early onset or family history). This finding is not a direct indicator of glaucoma, cataracts, or retinopathy, which involve the optic nerve/eye lens, or retinal vessels respectively.
