Can Hepatitis B Cause Blurred Vision?

Hepatitis B and Your Blurred Vision: Understand the Causes

Hepatitis B is a viral liver infection transmitted through infected blood, sexual fluids (semen and vaginal secretions), and from an infected mother to her child during childbirth. Though it mainly damages the liver, severe conditions may also affect other organs, like the eyes.

Read on to learn the effect of hepatitis B on your eyes.

How Does Hepatitis B Affect Your Eyes?

Hepatitis B rarely affects the eyes directly; however, immune-mediated complications or side effects from certain treatments may lead to ocular symptoms. Your eyes are either directly affected by the disease or from the side effects of medicines taken for hepatitis. Here are some of the common eye issues caused by hepatitis B:

1. Yellow Eyes

Due to hepatitis B, your liver loses its functioning efficiency, interrupting bilirubin excretion produced from the breakdown of red blood cells. Therefore, bilirubin builds up in your body, yellowing the skin and the white part of the eyes. However, this is a temporary condition and gets normal once the bilirubin level becomes normal.

2. Interferon-Associated Retinopathy

The retina is a light-sensitive tissue located at the back of your eyes. Interferon-containing medicines can affect the retina, causing blurred vision or other eye-related issues called retinopathy (leaking or swelling of blood vessels inside the retina).

Hepatitis B is treated with interferon-containing medicines as they belong to the immunity booster protein family, which can fight the hepatitis B virus. However, interferon was historically used, current first-line treatments for chronic HBV are nucleos(t)ide analogs (e.g., entecavir, tenofovir), which have fewer ocular side effects. Interferon is less commonly used today due to its side-effect profile.

What Eye Complications Does Hepatitis Cause?

Hepatitis B (HBV) is an infection of liver cells that can even lead to liver cancer. It is transmitted through transfusions of infected blood, sexual contact, or from a mother to the child during pregnancy.

Apart from symptoms like fever, fatigue, and vomiting, HBV also causes the following eye complications:

● Optic Neuritis and Uveitis

Optic neuritis involves the sudden inflammation of the optic nerve, whereas uveitis affects the front part of the eye. Both are thought to be autoimmune reactions, possibly triggered by the presence of hepatitis B virus (HBV).

● Third Nerve Palsy

The third cranial nerve, or oculomotor nerve, controls the dilation of pupils and movement of the eyes. This nerve may get temporarily paralyzed due to hepatitis B. You may experience headaches, pain in your eyes, and inability to dilate your eyes due to third nerve palsy. In such cases, seek medical assistance at the earliest.

● Retinal Vasculitis

Vasculitis is the inflammation of blood vessels in the eye, often triggered by bacterial or viral infections. When it affects the retinal vessels, blood flow to the retina decreases, leading to "cotton wool spots" on the retina.

How to Protect Your Eyes from the Effects of Hepatitis?

When it comes to protecting your eyes from the impact of hepatitis, here are a few things you must know:

• Individuals diagnosed with hepatitis must manage both their liver and associated eye conditions. While hepatitis B and C frequently require antiviral medications like interferon, some hepatitis types, such as hepatitis A, may not need medication.
• However, avoiding alcohol is essential in any of these conditions because it can exacerbate liver and eye issues.
• Hepatitis-related eye issues can differ in type and severity. Artificial tears or lubricating eye drops can help relieve mild symptoms like dry eyes.
   

There is no single standardized treatment for third nerve palsy; management depends on identifying and treating the underlying cause, and many cases improve over time with appropriate medical supervision. Access to the best treatment depends on each patient's unique situation because new hepatitis medications are being developed, and some recently approved drugs are expensive.

Therefore, getting a health insurance policy from reputed providers is essential to access quality treatment without bearing out-of-pocket expenses.
 

Consult Your Healthcare Provider
 

• It’s essential to seek your healthcare provider’s guidance to get the most appropriate treatment plan.
• Early and effective management of hepatitis can sometimes prevent eye complications from developing.
• If you are diagnosed with hepatitis, you should have a comprehensive eye test before starting any treatment and follow your eye doctor’s recommendations.
• In case you are taking interferon or similar medications, discuss with your eye doctor whether you need more frequent eye check-ups or special precautions.
• A baseline eye exam helps your doctor detect any changes in your eyes caused by hepatitis or its treatment and decide if further intervention is needed.
   

Staying proactive and maintaining regular communication with both your liver and eye specialists is the best way to protect your vision while managing hepatitis.

Hepatitis B and its potential eye-related effects can vary widely depending on factors such as disease severity, individual health conditions, and the type of treatment used. Always seek the advice of a qualified healthcare provider, hepatologist, or ophthalmologist regarding any medical condition, symptoms, or treatment options.
