Arcus senilis is a gray-white arc around which structure of the eye?

Explanation:
Arcus senilis appears as a gray-white ring at the edge of the cornea where it meets the sclera—the corneal-scleral junction, known as the limbus. This peripheral lipid deposition in the corneal stroma creates the arc surrounding the cornea. It is common with aging and usually benign, though in younger individuals it can signal lipid abnormalities that may warrant checking blood lipids. It does not form around the iris, retina, or pupil.
