Jaundice of the Sclera

What is Jaundice of sclera?

Jaundice of the sclera, often described as “yellowing of the whites of the eyes,” is a visible sign that the body’s bilirubin level is elevated. Bilirubin is a yellow‑pigmented waste product formed when red blood cells break down. Under normal circumstances the liver processes bilirubin and excretes it in the stool. When this pathway is disrupted, bilirubin accumulates in the bloodstream and deposits in tissues that contain elastic fibers, such as the sclera (the tough, white outer layer of the eye). Because the sclera is thin and highly vascular, even modest increases in bilirubin become apparent as a yellow tint.

While scleral icterus is most commonly associated with liver disease, it can also appear in a range of other medical conditions. Recognizing it early can prompt timely evaluation of potentially serious systemic illnesses.

Common Causes

The following 9 conditions are among the most frequent reasons for scleral jaundice. They are grouped by the underlying mechanism that raises bilirubin.

• Hepatocellular injury – viral hepatitis (A, B, C, D, E), alcoholic liver disease, non‑alcoholic steatohepatitis (NASH), drug‑induced liver injury, or autoimmune hepatitis.
• Bile duct obstruction – gallstones, cholangiocarcinoma, pancreatic head cancer, or strictures from previous surgery.
• Hemolysis – accelerated breakdown of red blood cells due to sickle cell disease, hereditary spherocytosis, thalassemia, G6PD deficiency, or autoimmune hemolytic anemia.
• Genetic disorders of bilirubin metabolism – Gilbert’s syndrome and Crigler‑Najjar syndrome.
• Sepsis or severe infection – especially in newborns (e.g., neonatal sepsis) or in patients with overwhelming bacterial infection.
• Medication‑related jaundice – certain antibiotics (e.g., amoxicillin‑clavulanate), anticonvulsants, sulfonamides, or herbal supplements can cause cholestasis or liver cell damage.
• Pancreatic disorders – pancreatitis or tumors that compress the common bile duct.
• Congestive heart failure – right‑sided failure can cause hepatic congestion and reduced bilirubin clearance.
• Neonatal physiologic jaundice – immature liver enzymes in newborns; usually resolves within the first week but can progress to kernicterus if untreated.

Associated Symptoms

Scleral jaundice rarely occurs in isolation. Look for other signs that point toward the underlying cause.

• Yellowing of the skin, especially on the palms and soles.
• Dark urine (bilirubin‑pigmented) and pale, clay‑colored stools.
• Pruritus (itchy skin) – common in cholestatic jaundice.
• Abdominal pain or fullness, especially in the right upper quadrant.
• Fatigue, malaise, and loss of appetite.
• Fever, chills, or rigors (suggesting infection or sepsis).
• Weight loss or night sweats (possible malignancy).
• Swelling of the legs or abdomen (ascites) in advanced liver disease.
• Blood in the stool or black, tarry stools (upper GI bleed).

When to See a Doctor

Because jaundice can represent a spectrum from benign to life‑threatening, seek medical attention promptly if you notice any of the following:

• Scleral yellowing that persists for more than 24‑48 hours.
• Accompanying dark urine, pale stools, or intense itching.
• Severe abdominal pain, especially in the right upper quadrant.
• Fever > 101 °F (38.3 °C) or a feeling of “severe illness.”
• Confusion, difficulty concentrating, or personality changes (possible hepatic encephalopathy).
• Rapid weight loss, loss of appetite, or vomiting.
• History of liver disease, recent travel to endemic hepatitis areas, or recent use of new medications/herbal products.
• In infants: any yellowing of the eyes or skin, especially if the baby is lethargic, feeding poorly, or has a high‑pitched cry.

Diagnosis

Evaluation begins with a thorough history and physical exam, followed by targeted laboratory and imaging studies.

History & Physical Examination

• Onset, duration, and progression of jaundice.
• Medication, supplement, and alcohol use.
• Travel, exposure to hepatitis‑infected individuals, or blood products.
• Family history of hemolytic or metabolic disorders.
• Physical clues: liver enlargement, splenomegaly, ascites, spider angiomas, asterixis, or peripheral edema.

Laboratory Tests

• Comprehensive metabolic panel – includes total and direct bilirubin, ALT, AST, ALP, GGT, and albumin.
• Complete blood count (CBC) – assesses anemia, hemolysis, or infection.
• Hemolysis work‑up – haptoglobin, lactate dehydrogenase (LDH), reticulocyte count, peripheral smear.
• Viral hepatitis serologies – HAV IgM, HBV surface antigen, HCV antibody & RNA.
• Autoimmune markers – ANA, SMA, anti‑LKM1 if autoimmune hepatitis suspected.
• Coagulation profile – PT/INR to gauge liver synthetic function.

Imaging

• Abdominal ultrasound – first‑line to detect gallstones, biliary dilatation, liver texture, or masses.
• CT or MRI – clarifies complex biliary or pancreatic lesions.
• MRCP (magnetic resonance cholangiopancreatography) – non‑invasive view of the biliary tree.
• Endoscopic ultrasound (EUS) or ERCP – both diagnostic and therapeutic for obstructive causes.

Special Tests

• Serum ceruloplasmin and 24‑hour urinary copper for Wilson disease (younger adults).
• Alpha‑1 antitrypsin level and phenotype.
• Genetic testing for Gilbert’s or Crigler‑Najjar syndromes if routine work‑up is unrevealing.

Treatment Options

Treatment is directed at the underlying cause; the scleral discoloration resolves as bilirubin normalizes.

Medical Management

• Viral hepatitis – antiviral therapy (e.g., entecavir, tenofovir for HBV; direct‑acting antivirals for HCV).
• Biliary obstruction – endoscopic removal of stones, stenting of strictures, or surgical resection of tumors.
• Hemolytic anemia – stop offending drugs, treat underlying immune process (corticosteroids, rituximab), or manage enzyme deficiencies (e.g., folic acid supplementation).
• Drug‑induced liver injury – discontinue the culprit, monitor liver function, and provide supportive care.
• Autoimmune hepatitis – corticosteroids ± azathioprine.
• Alcohol‑related disease – complete abstinence, nutritional support, and possibly pentoxifylline or corticosteroids for severe alcoholic hepatitis.
• Newborns – phototherapy for physiologic or pathological jaundice; exchange transfusion for severe hyperbilirubinemia.

Supportive & Home Care

• Maintain adequate hydration (helps renal excretion of bilirubin).
• Balanced diet rich in fruits, vegetables, lean protein; avoid excessive fats and alcohol.
• Consider ursodeoxycholic acid for certain cholestatic conditions (under physician guidance).
• Pruritus relief – cool showers, oatmeal baths, antihistamines, or prescribed cholestyramine.
• Regular follow‑up labs to track bilirubin trends.

Prevention Tips

While not all causes are preventable, many risk factors can be modified.

• Practice safe sex and avoid sharing needles to reduce hepatitis B and C transmission.
• Get vaccinated against hepatitis A and B.
• Limit alcohol intake; follow guidelines (≤ 2 drinks/day for men, ≤ 1 drink/day for women).
• Use medications as prescribed; discuss liver‑related side effects with your clinician.
• Maintain a healthy weight to lower the risk of non‑alcoholic fatty liver disease.
• Adopt a balanced diet low in saturated fat and high in fiber.
• For newborns, ensure timely breastfeeding and follow the pediatrician’s schedule for bilirubin screening.
• Wear protective gear when handling chemicals or solvents that can harm the liver.

Emergency Warning Signs

Key Takeaways

Scleral jaundice is an easily observable clue that something is amiss with the liver, biliary system, or red‑blood‑cell turnover. Because the underlying causes range from benign (e.g., Gilbert’s syndrome) to life‑threatening (e.g., acute viral hepatitis or biliary obstruction), early recognition and evaluation are essential. Prompt medical assessment—including blood tests and imaging—helps pinpoint the cause and guides appropriate therapy. Lifestyle choices, vaccinations, and safe medication practices can markedly reduce the risk of many reversible etiologies.

Always remember: if the yellowing of your eyes is accompanied by alarming symptoms such as severe pain, confusion, high fever, or vomiting, treat it as a medical emergency and call emergency services or go to the nearest emergency department.
