Scleral Icterus
Scleral icterus is a condition that makes the white part of the eyes turn yellow. This is because of jaundice, which happens when there’s too much bilirubin in the blood. Bilirubin is a yellow pigment made when red blood cells break down.
This yellowing can be a sign of many health issues, like problems with the liver, gallbladder, or blood. Knowing about scleral icterus and its causes is key to staying healthy and avoiding serious problems.
What is Scleral Icterus?
Scleral icterus is a condition where the white part of the eye turns yellow. This happens when there’s too much bilirubin in the blood. The liver usually breaks down bilirubin, but if it can’t, the eyes turn yellow.
The sclera is the white outer layer of the eye. It’s covered by a thin membrane called the conjunctiva. When bilirubin levels rise, the blood vessels in the conjunctiva become more visible, making the sclera yellow.
Definition and Explanation
Scleral icterus is when the sclera turns yellow because of too much bilirubin in the blood. Bilirubin is a yellow pigment from broken-down red blood cells. Normally, the liver gets rid of bilirubin through the digestive system. But if the liver or biliary system is not working right, bilirubin builds up, causing yellow skin and eyes.
Anatomy of the Eye and Sclera
To understand scleral icterus, knowing the eye’s anatomy is helpful:
| Eye Structure | Description |
|---|---|
| Sclera | The tough, white outer layer of the eye that provides protection and structure |
| Conjunctiva | The thin, clear membrane that covers the sclera and lines the inside of the eyelids |
| Cornea | The clear, dome-shaped surface at the front of the eye that helps focus light |
| Iris | The colored part of the eye that controls the size of the pupil |
| Pupil | The black opening in the center of the iris that allows light to enter the eye |
When bilirubin levels are high, the sclera and conjunctiva turn yellow. This is often the first sign of liver disease or other conditions affecting bilirubin.
Causes of Scleral Icterus
Scleral icterus can stem from several health issues. These include liver diseases, biliary blockages, hemolytic anemia, and newborn jaundice. Knowing these causes is key to spotting and treating scleral icterus early.
Liver Diseases
Liver diseases like hepatitis and cirrhosis can mess up bilirubin processing. This leads to scleral icterus. Here’s a list of liver diseases that might cause it:
| Liver Disease | Description |
|---|---|
| Hepatitis | Inflammation of the liver caused by viral infections, alcohol, or other factors |
| Cirrhosis | Scarring of the liver tissue that impairs its function |
| Liver cancer | Malignant growth in the liver that can disrupt bilirubin metabolism |
Biliary Obstruction
Biliary obstruction happens when bile ducts get blocked. Gallstones are a common cause. They stop bile from flowing, leading to bilirubin buildup.
Hemolytic Anemia
Hemolytic anemia means red blood cells break down too fast. This releases hemoglobin, which turns into bilirubin. Too much bilirubin can cause scleral icterus.
Newborn Jaundice
Newborn jaundice is common in infants. It happens when a baby’s liver can’t handle bilirubin yet. Usually, it goes away as the liver grows. But sometimes, treatment is needed to avoid problems.
Other causes include Gilbert’s syndrome and some medicines. Gilbert’s syndrome affects how the liver deals with bilirubin. Certain drugs can also mess with bilirubin levels.
Symptoms Associated with Scleral Icterus
Scleral icterus often comes with other symptoms that help find the cause. These signs can change based on the disease causing the yellow eyes. Common symptoms include:
| Symptom | Description |
|---|---|
| Yellowing of skin | The skin may turn yellow, mainly on the face, chest, and belly. |
| Dark urine | Urine looks darker, like tea or amber. |
| Pale stools | Stools are lighter, often gray or clay-colored. |
| Fatigue | People with scleral icterus feel very tired and weak. |
| Abdominal pain | Pain in the upper right belly, near the liver, can happen. |
Knowing these symptoms and their link to scleral icterus is key. Seeing yellow skin, dark urine, pale stools, fatigue, or belly pain with yellow eyes means you should see a doctor.
Early treatment of the cause is vital to avoid serious problems and improve health. If you see these signs, and they don’t go away or get worse, get medical help fast.
Diagnosing Scleral Icterus
When someone’s eyes turn yellow, doctors use a detailed method to find out why. They look at the eyes, skin, and blood, and might use scans too.
Physical Examination
A doctor will check the eyes, skin, and other parts for yellow signs. They might also feel the belly to see if the liver is big or sore.
Blood Tests
Blood tests are key in finding out what’s causing the yellow eyes. A bilirubin test checks bilirubin levels. Liver function tests look at liver health by measuring certain substances.
Imaging Studies
Imaging tests help see the liver and other areas. An ultrasound is often first because it’s safe and can spot problems. A CT scan or MRI might be used for clearer pictures.
Doctors use all this info to figure out why the eyes turned yellow. Then, they make a plan to help the patient.
Treatment Options for Scleral Icterus
Treatment for scleral icterus aims to fix the cause of the condition. The method used depends on the reason for bilirubin buildup. Healthcare providers work to lower bilirubin levels and clear the yellow color from the sclera.
Addressing the Underlying Cause
It’s key to find and treat the cause of scleral icterus. For instance, if liver disease like hepatitis or cirrhosis is the issue, antiviral drugs or other meds might be needed. If a blockage in the bile ducts is the problem, bile duct surgery could be required to clear the blockage.
Medications
Medications vary based on the cause of scleral icterus. Antibiotics might be given for bacterial infections affecting the liver or bile system. Corticosteroids could be used to lessen inflammation in autoimmune hepatitis. Sometimes, drugs that help bile flow or lower bilirubin production are suggested.
Lifestyle Changes
Changing your lifestyle can help treat scleral icterus and keep your liver healthy. Eating a healthy diet full of fruits, veggies, and whole grains supports liver function. It’s important to avoid alcohol as it can harm the liver. Regular exercise and a healthy weight also help the liver and reduce risks.
Complications of Untreated Scleral Icterus
Ignoring the warning signs of scleral icterus can lead to severe health consequences. When the underlying cause of yellowing in the whites of the eyes remains unaddressed, it can progress to more serious conditions affecting the liver and other organs.
One of the most concerning complications of untreated scleral icterus is liver failure. As the liver continues to deteriorate, it loses its ability to filter toxins and perform essential functions. This can result in a buildup of harmful substances in the body, leading to potentially life-threatening situations.
Another complication associated with prolonged liver damage is cirrhosis. Cirrhosis occurs when healthy liver tissue is replaced by scar tissue, compromising the organ’s structure and function. This can further exacerbate the symptoms of scleral icterus and contribute to the development of other serious health issues.
In advanced stages of liver disease, individuals may experience hepatic encephalopathy, a condition characterized by confusion, altered mental state, and even coma. This occurs when the damaged liver fails to remove toxins from the blood, allowing them to accumulate and affect brain function.
Untreated liver conditions can also lead to blood clotting issues. The liver plays a critical role in producing clotting factors. When its function is impaired, the body’s ability to form blood clots is compromised. This can result in excessive bleeding and further complications.
Seeking prompt medical attention and addressing the underlying cause of scleral icterus is essential to prevent these serious complications. Early intervention and appropriate treatment can help restore liver function, improve overall health, and reduce the risk of long-term consequences.
Preventing Scleral Icterus
Scleral icterus is a sign, not a disease itself. But, taking care of your liver and catching problems early can stop it. Healthy habits and regular doctor visits can lower your risk of getting conditions that cause scleral icterus.
Maintaining Liver Health
Keeping your liver healthy is key to avoiding scleral icterus. Here are some ways to do it:
- Hepatitis vaccination: Vaccines against hepatitis A and B protect your liver from viruses.
- Avoiding toxins: Stay away from harmful substances like alcohol, drugs, and chemicals that harm the liver.
- Balanced diet: Eating lots of fruits, veggies, whole grains, and lean proteins helps your liver.
- Exercise: Regular exercise keeps you at a healthy weight and boosts liver health.
| Liver Health Tip | Benefit |
|---|---|
| Hepatitis vaccination | Prevents viral liver infections |
| Avoiding toxins | Reduces liver damage |
| Balanced diet | Supports liver function |

Early Detection and Treatment of Underlying Conditions
Seeing your doctor regularly is important. It helps find problems that could lead to scleral icterus early. Catching and treating liver diseases, blockages, or blood issues early can stop jaundice and its symptoms, like scleral icterus. If you have a family history of liver issues or other risks, talk to your doctor about more frequent check-ups.
When to Seek Medical Attention
If you see your eyes turning yellow, watch for other symptoms and how long it lasts. Mild cases might go away by themselves. But, if it doesn’t get better or gets worse, you should see a doctor fast. Getting help early can stop problems and make things better.
Persistent or Worsening Symptoms
If your eyes stay yellow or get yellower, see a doctor right away. Long-lasting yellow eyes might mean you have a serious issue. Your doctor will check you, run tests, and figure out why your eyes are yellow. Finding out early helps start treatment sooner and manage your condition better.
Accompanying Pain or Discomfort
Sometimes, yellow eyes come with pain, fever, tiredness, or dark pee. If you have these symptoms too, get medical help quickly. These signs might mean you have a serious problem that needs quick attention. Your doctor will look at your symptoms, do tests, and make a plan to fix your yellow eyes and any pain.
