Anatomy of the eye

Jaundice mainly affects the front of the eye as this is where the yellow pigment would be visible.

It's important to understand the anatomy of the front of the eye to understand how jaundice affects the eye. The front part of the eye is made of several different parts:

Eyelid and lashes: Upper and lower lids and lashes offer eyes protection from dirt and dust. They are also used to blink so the eyes stay moist. If jaundice is present, both the outer eyelids and the underside of the eyelid that is visible when the lid is lifted may have a yellow tint.

Pupil: The pupil is the dark center of each eye that controls the amount of light that enters. Generally, jaundice does not discolor the pupils.

Iris: The iris is the colored part of the eye immediately surrounding the pupils. It has muscles that contract the pupils. Yellowing may be seen in the iris if a person has jaundice.

Sclera: The whites of the eye. The sclera surrounds the iris and protects the fragile structures on the inside of the eye. Yellow eyes are often first noticed because the sclera yellows
