EXAMINATION OF THE CORNEA
WITH DIFFUSE ILLUMINATION
Arcus senilis is a build-up of
cholesterol and other lipids in the
peripheral cornea. It appears as a
whitish or yellowish ring just inside
the limbus. It is found in 60% of the
patients between 40 and 60 years
old and almost all patients over 80,
thus is commonly seen on
biomicroscopic examination.
