What is the difference between jaundice and icterus?
Icterus is also known as jaundice or yellow jaundice. It refers to an excessive accumulation of a yellow pigment in the blood and tissues. When icterus has been present for any length of time, it will discolor many tissues and will become visible as jaundice on most body surfaces, including the skin.
How long does it take for scleral icterus to resolve?

Why is icterus seen in sclera?
What causes scleral icterus? Bilirubin is normally produced when red blood cells (RBCs) break down. It is then taken up by the liver and secreted into the bile. Excessive destruction of RBCs (hemolysis) or disruption of the bilirubin pathway at some point can lead to the development of scleral icterus.
What is jaundice sclera?
Jaundice is a condition in which the skin, sclera (whites of the eyes) and mucous membranes turn yellow. This yellow color is caused by a high level of bilirubin, a yellow-orange bile pigment. Bile is fluid secreted by the liver.
What causes scleral icterus?
In the elderly, scleral icterus is most often caused by obstruction of the bile ducts, referred to as obstructive jaundice. The most common causes include gallstones and malignancy, such as pancreatic cancer and cholangiocarcinoma. In adults, scleral icterus can also occur due to liver dysfunction.
What level of bilirubin causes icterus?
The normal serum levels of bilirubin are less than 1 milligram per deciliter (mg/dL). However, the clinical presentation of jaundice with peripheral yellowing of the eye sclera, also called scleral icterus, is best appreciated when serum bilirubin levels exceed 3 mg/dl.
