Caption: Arcus senilis. Illustration of a close-up of an eye showing the condition arcus senilis, in which a grey-white circle in the periphery of the cornea occurs around the edge of the iris. Arcus senilis develops due to an infiltration of fatty material (hyperlipidaemia) in this iris region of the eye. The particles floating around this image represent the lipoprotein infiltration that consists of the following varied elements: triglyceride (purple); phospholipid (green); cholesterol (yellow). Most elderly people develop arcus senilis. The ring never spreads to the iris centre, it is not related to health, and vision is unaffected. This condition in the young is termed arcus juvenilis.
