Why Is My Vision Yellowish When I Have a Fever?

Introduction

Your vision becomes yellowish when you have a fever because of a condition known as scleral icterus. This is a rare but serious symptom that can indicate underlying health issues. While it is not common for fever to cause yellow vision, there are several medical conditions that can lead to this symptom, including liver disease, viral hepatitis, anemia, and other serious health conditions. If you experience this symptom, it is important to seek medical attention promptly.

Common Causes of Yellow Vision

Viral Hepatitis: A viral infection that can affect the liver and cause jaundice, which may lead to yellowing of the sclera. Cirrhosis: Scarring of the liver due to long-term damage, which can result in increased bilirubin levels and jaundice. Anemia: A condition where the body does not have enough healthy red blood cells, which can lead to icterus. Subconjunctival Hemorrhage: A rupture of the blood vessels under the conjunctiva, causing discoloration. Neonatal Jaundice: This is a common condition in newborns due to the buildup of bilirubin in their blood. Sarcoidosis: A condition where small lumps of inflammatory cells (granulomas) form in various organs, including the liver.

Understanding Scleral Icterus

When the whites of the eyes (sclera) become yellow, it is known as scleral icterus. This is typically a sign of jaundice, which is caused by an excess of bilirubin in the blood. Bilirubin is a byproduct of the normal breakdown of red blood cells and is usually eliminated by the liver. However, if this process is hindered, bilirubin accumulates in the body's tissues, including the eyes, leading to their yellowing.

Causes of Elevated Bilirubin Levels

Biomedical conditions that can cause elevated levels of bilirubin include:

Chronic liver disease due to alcohol or other toxins. Haemolytic anemia, in which red blood cells break down faster than the body can process them. Infections such as hepatitis or mononucleosis, which can affect the liver's ability to process bilirubin.

When to Seek Medical Attention

It is essential to see a doctor if your vision becomes yellowish, even if the fever resolves quickly. Ignoring this symptom can be dangerous, especially if it is a sign of more serious health issues. Your primary care physician can perform blood tests to determine the underlying cause of the yellowing of the eyes and provide appropriate treatment. Treatment may include:

Artificial tears to lubricate the eyes. Stopping alcohol consumption, if applicable. Medications to treat viral hepatitis or other infections.

Conclusion

The yellowing of the eyes when you have a fever should prompt immediate medical attention. While it may seem unusual, several serious medical conditions can cause this symptom. It is vital to understand the potential causes, such as viral hepatitis, cirrhosis, anemia, and liver damage, as early detection and treatment are crucial for better health outcomes.
