Corneal arcus as an indicator of hypercholesterolemia

Area of Science:

• Ophthalmology
• Cardiology
• Clinical Biochemistry

Background:

• Corneal arcus has historically been considered a normal, age-related ocular finding.
• Recent studies suggest a link between corneal arcus and elevated cholesterol, particularly in younger individuals.
• The association in the elderly population has been less clear in prior literature.

Purpose of the Study:

• To investigate the association between corneal arcus and serum cholesterol levels across all age groups.
• To determine if corneal arcus is a reliable indicator of hypercholesterolemia and cardiovascular disease risk irrespective of age.

Main Methods:

• Cross-sectional study design.
• Ophthalmic examination to identify corneal arcus.
• Serum lipid profile analysis to measure cholesterol levels.

Main Results:

• Corneal arcus was significantly associated with elevated serum cholesterol levels.
• This association was consistent across both younger and elderly participants.
• The presence of corneal arcus independently predicted higher cholesterol levels.

Conclusions:

• Corneal arcus serves as a valuable clinical sign for detecting elevated cholesterol, regardless of patient age.
• Identifying corneal arcus can prompt earlier screening for hypercholesterolemia and cardiovascular disease risk.
• Ophthalmologists can play a crucial role in cardiovascular risk assessment through the detection of corneal arcus.
