What is orange ring around pupil?

An orange ring around the pupil is usually referred to as a "corneal arcus" or "arcus senilis." It appears as a thin, grey or white ring around the outer edge of the iris and can affect one or both eyes. It generally occurs in older people and is caused by a buildup of cholesterol or fat deposits in the cornea. Although it is usually a benign condition, it can indicate high cholesterol levels and a risk of developing heart disease. Therefore, it is advisable to have a complete physical exam to determine if there are any underlying health issues associated with the presence of an orange ring around the pupil.
