High cholesterol mainly affects blood vessels, including those supplying the eyes. Over time, this can influence both sight and eye health.
Eye changes linked to high cholesterol
Fatty deposits may build up in blood vessel walls, reducing blood flow. Occasionally, small cholesterol fragments can travel and block vessels in or around the eye.
- A pale ring around the cornea arcus can appear in some people
- Cholesterol plaques in neck arteries may cause eye strokes
- Blocked retinal vessels can lead to sudden vision loss
- Changes are more likely with long-standing, uncontrolled cholesterol
Protecting your eyes and health
Managing cholesterol helps reduce the risk of heart disease and serious eye events. Regular eye examinations can also reveal early signs of vascular problems.
- Follow medical advice on diet, exercise, and any prescribed tablets
- Report sudden vision changes immediately, even if they quickly improve
- Attend routine eye checks where retinal photographs may be taken
- Do not stop cholesterol medication without discussing it with your doctor
