Jaundice of the Eyes (Scleral Icterus)

What is Jaundice of eyes?

Jaundice of the eyes, also called scleral icterus or “yellow eyes,” is a visible yellowing of the white part of the eye (the sclera). The discoloration occurs when the blood contains an excess of bilirubin—a yellow pigment produced during the normal breakdown of red blood cells. When bilirubin levels rise above the normal range (≈ 0.3 mg/dL), it can deposit in tissues, giving the skin, mucous membranes and sclera a yellow hue.

Because the sclera is thin and richly vascularized, it often shows jaundice before the skin does, making yellow eyes an early clinical clue that something is altering the body’s bilirubin metabolism.

Common Causes

Many medical conditions can raise bilirubin enough to cause scleral icterus. The most frequent causes fall into three categories: liver disease, hemolysis (excess red‑cell breakdown), and obstructive problems in the biliary system.

• Hepatitis A, B, C or alcoholic hepatitis – inflammation damages liver cells, reducing bilirubin clearance.
• Non‑alcoholic fatty liver disease (NAFLD) and non‑alcoholic steatohepatitis (NASH) – common in obesity and metabolic syndrome.
• Cirrhosis (any cause) – scar tissue disrupts normal liver function.
• Gallstones or biliary strictures – block the flow of bile, causing bilirubin to back up into the blood.
• Pancreatic head cancer – can compress the common bile duct (Courvoisier’s sign).
• Hemolytic anemia (e.g., sickle cell disease, hereditary spherocytosis, autoimmune hemolysis) – rapid red‑cell destruction releases large amounts of bilirubin.
• Gilbert’s syndrome – a benign genetic defect in bilirubin processing that can become symptomatic during fasting, stress or illness.
• Drug‑induced liver injury – acetaminophen overdose, certain antibiotics, antiretrovirals, and herbal supplements.
• Sepsis or severe infections – can cause cholestasis (reduced bile flow) and raise bilirubin.
• Newborn physiologic jaundice – immature liver enzymes in infants; rarely persists past the first few weeks.

Associated Symptoms

Jaundice of the eyes rarely appears in isolation. Look for other signs that point toward the underlying cause:

• Generalized yellowing of the skin, especially on the palms and soles.
• Dark urine (bilirubin‑colored) and pale or clay‑colored stools.
• Abdominal pain—particularly in the right upper quadrant—or a feeling of fullness.
• Itching (pruritus) caused by bile salts depositing under the skin.
• Fatigue, weakness, or unintentional weight loss.
• Fever, chills, or rigors (suggesting infection or cholangitis).
• Swelling of the abdomen (ascites) or legs (edema) in advanced liver disease.
• Dark, sticky stools in newborns (meconium) that become lighter as jaundice progresses.
• Joint pain or swelling if an autoimmune hemolytic process is present.

When to See a Doctor

Yellowing of the eyes is a signal that something is wrong with bilirubin metabolism. Prompt medical evaluation is advisable if any of the following occur:

• The yellow discoloration spreads to the skin or persists for more than 2 days.
• Accompanying abdominal pain, especially if you feel a tender lump under the ribs.
• Fever ≥ 38 °C (100.4 °F) with chills.
• Dark urine and pale stools that develop suddenly.
• Severe itching that disrupts sleep.
• Confusion, slurred speech, or difficulty staying awake (possible hepatic encephalopathy).
• History of liver disease, recent travel to areas with hepatitis risk, or use of hepatotoxic drugs.

For infants, seek care if the yellow color involves the skin, lasts longer than 2 weeks, or is associated with poor feeding, lethargy, or a firm abdomen.

Diagnosis

Doctors combine a visual exam with laboratory and imaging studies to determine why bilirubin is elevated.

History & Physical Examination

• Detailed medication and alcohol use review.
• Travel, sexual history, and vaccination status (hepatitis risk).
• Family history of liver or blood disorders.
• Full physical exam focusing on the abdomen, liver size, and signs of chronic liver disease (spider angiomas, palmar erythema, caput medusae).

Laboratory Tests

• Serum bilirubin – total and direct (conjugated) fractions.
• Liver function panel: AST, ALT, alkaline phosphatase, GGT, albumin, PT/INR.
• Complete blood count (CBC) – anemia or signs of hemolysis.
• Haptoglobin, lactate dehydrogenase (LDH), and reticulocyte count (if hemolysis suspected).
• Viral hepatitis serologies (HBsAg, anti‑HBc, anti‑HCV).
• Autoimmune markers (ANA, ASMA) for autoimmune hepatitis.
• Iron studies & ferritin (hemochromatosis) when indicated.

Imaging

• Abdominal ultrasound – first‑line to assess liver texture, gallbladder stones, bile duct dilation.
• CT or MRCP (magnetic resonance cholangiopancreatography) – detailed view of biliary tree or pancreatic mass.
• Elastography (FibroScan) – non‑invasive measurement of liver fibrosis.

Special Procedures

• Endoscopic retrograde cholangiopancreatography (ERCP) – both diagnostic and therapeutic for bile‑duct obstruction.
• Liver biopsy – reserved for unclear cases or when cirrhosis, autoimmune hepatitis, or metabolic disease is suspected.

Treatment Options

Treatment is directed at the underlying cause; the yellowing itself resolves as bilirubin levels normalize.

Medical Therapies

• Antiviral or antimicrobial therapy for hepatitis B/C, bacterial cholangitis, or parasitic infections.
• Corticosteroids or immunosuppressants for autoimmune hepatitis.
• Ursodeoxycholic acid for certain cholestatic conditions (primary biliary cholangitis).
• Phototherapy for severe neonatal jaundice or adult cases where bilirubin is dangerously high.
• Exchange transfusion in newborns with bilirubin > 20 mg/dL or signs of kernicterus.
• Chemo‑embolization, surgery, or stenting for obstructing tumors or gallstones.
• Iron chelation or phlebotomy for hereditary hemochromatosis that presents with liver dysfunction.

Home & Supportive Care

• Hydration – adequate fluids help the liver excrete bilirubin.
• Balanced diet rich in fruits, vegetables, lean protein and limited saturated fats.
• Avoid alcohol and hepatotoxic over‑the‑counter meds (e.g., high‑dose acetaminophen).
• Use gentle skin moisturizers and antihistamine creams if itching is troublesome.
• For newborns, ensure nursing on demand and monitor weight gain; phototherapy units can be used at home under pediatric guidance.

Prevention Tips

While not all causes are preventable, many risk factors are modifiable:

• Vaccinate against hepatitis A and B.
• Practice safe sex and avoid sharing needles to reduce viral hepatitis risk.
• Limit alcohol intake to ≤ 2 drinks/day for men and ≤ 1 drink/day for women.
• Maintain a healthy weight (BMI < 25 kg/m²) to lower NAFLD risk.
• Stay current on routine vaccinations for infants (including the hepatitis B series).
• Use medications responsibly; follow dosing instructions and discuss liver‑related side effects with your provider.
• Wear protective gear when handling chemicals or solvents that can damage the liver.
• Seek prompt treatment for infections or fevers that could progress to cholestatic liver injury.
