Hepatitis is considered highly contagious and there are several types of the virus. People who have hepatitis A and B may also have sclera icterus because the infection affects the liver. The excessive alcohol consumption may cause serious liver damage something that prevents the organ from executing its filtering activity properly. Alcoholic hepatitisĮxcessive intake of alcohol may contribute to alcohol hepatitis that involves liver inflammation. When this happens, the whites of eyes turn yellow or orangey. An infection caused by this virus may affect liver cells because it causes obstruction, which in turn affects the function of an individual’s liver leading to increased amount of bilirubin in blood. Epstein-Barry virusĪ stain of herpes virus referred to as Epstein-Barry virus, which is also known as mono, may cause sclera icterus. Biliary colic may occur with any type of gallbladder disease. The pain can radiate to reach the back or shoulder. Biliary colic may also induce pain within the upper right side of a person’s abdominal area. 4Ĭauses of scleral icterus are: 1,2,3 Biliary colicĪlso referred to as gallbladder attack, biliary colic may contribute to sclera icterus since gallstones tends to block an individual’s bile duct.
Pre-hepatic sclera icterus occurs before bilirubin reaches the liver, hepatic or hepatocellular scleral icterus occurs when bilirubin has reached the liver, and post-hepatic or cholestatic occurs after when bilirubin has been conjugated in the individual’s liver. Scleral icterus can occur before, during, and after liver processing activity depending on what is causing the liver to malfunction. When the liver doesn’t function as it should, bilirubin isn’t released out of the person’s body and it remains circulating in blood and ends up in different parts of the individual’s body including the eyes. The coloring of the person’s eyes may fall under three classes: 1,2,3 However, sclera icterus doesn’t affect a person’s vision. Scleral icterus makes the white of eyes to become dark taking hues of bright yellow to something like dark orange. If the liver doesn’t function properly, the levels of this substance may elevate in blood causing sclera icterus or yellowing of a person’s eye part that is normally white in color. Bilirubin passes through the liver prior to being excreted from an individual’s body. Scleral icterus is linked to disorders of the liver that affect how the substance is expelled from the body. 2 Causes of Scleral Icterusīilirubin has an orangey to yellow appearance and it is created when red blood cells are broken down. Once the underlying condition is resolved, the discoloration may resolve or even managed. Scleral icterus may also indicate that there is obstruction of blood flow that prevents a person’s body from eliminating waste. Scleral icterus isn’t a disorder or disease in itself, but rather a symptom of an underlying condition or disease, usually of the liver.
The classic definition of scleral icterus is excessive presence of a substance known as bilirubin in an individual’s bloodstream that causes the whites of eyes to have a yellowish coloration. To help identify the cause, a person with sclera icterus will require proper testing for liver enzymes. In newborns sclera icterus occurs because their liver hasn’t matured. Scleral icterus manifests with symptoms like yellowing of an individual’s eye part that is usually white, and it can indicate a dysfunctional liver.
DEFINE SCLERAL ICTERUS SKIN
Yellowing of skin sparing the sclerae is indicative of carotenoderma which occurs in healthy individuals who consume excessive carotene-rich foods.Ĭopyright © 2023, StatPearls Publishing LLC.When an individual has yellow eyes, he or she is thought to have a problem with their liver like liver disease. Icterus acts as an essential clinical indicator for liver disease, apart from various other insults. With further increase in serum bilirubin levels, the skin will progressively discolor ranging from lemon yellow to apple green, especially if the process is long-standing the green color is due to biliverdin.īilirubin has two components: unconjugated(indirect) and conjugated(direct), and hence elevation of any of these can result in jaundice. Sclerae have a high affinity for bilirubin due to their high elastin content. The normal serum levels of bilirubin are less than 1mg/dl however, the clinical presentation of jaundice as scleral icterus (peripheral yellowing of the eye sclera), is best appreciated only when the levels reach more than 3 mg/dl. Deposition of bilirubin happens only when there is an excess of bilirubin, a sign of increased production or impaired excretion. Jaundice, also known as hyperbilirubinemia, is a yellow discoloration of the body tissue resulting from the accumulation of an excess of bilirubin.
