Arcus senilis is a grey-white ring or arc that appears at the edge of the cornea. It is common in older adults and usually does not affect vision.
Appearance and significance
The ring represents cholesterol and lipid deposits in the corneal periphery. It often becomes more noticeable with age.
- Typically seen in both eyes and spares the clear central cornea
- Does not cause pain or blur vision
- In younger people, it may be associated with raised blood lipids
- Eye examination helps distinguish it from more serious corneal problems
Management
Arcus senilis itself does not need treatment. Attention focuses on general health where appropriate.
- No drops or surgery are required for the ring
- Lipid profile testing may be advised in patients under about 50
- Healthy diet, exercise, and not smoking support cardiovascular health
- Routine eye checks continue to monitor overall eye status
