Can Liver Disease Cause Blurry Vision?

How Does Liver Disease Affect Your Eyes?

Blurred vision can often indicate health problems that affect more than just the eyes. Surprisingly, eye health and liver disease are interdependent, impacting everything from nerve function to nutrient absorption.

Thus, it is crucial to understand how liver conditions are related to blurry vision and how to better manage and improve the overall quality of life. Read ahead to understand the signs to look for and how liver diseases affect vision.

Is Liver Disease Related to Poor Eyesight?

Liver disease can affect vision both directly and indirectly. Vitamin A, which is essential for retinal health and night vision, is one of the essential nutrients processed by the liver. Liver damage impairs its ability to filter toxins and metabolise vitamins, which can result in toxic accumulation or deficiencies that affect the eyes.

For instance, night blindness, corneal ulcers, and dry eyes can result from a vitamin A deficiency brought on by liver disease. Furthermore, poor glucose regulation due to liver damage may exacerbate diabetes and raise the risk of diabetic retinopathy.

What are the eye-related signs and symptoms of liver diseases?

Liver diseases often lead to noticeable changes in the eyes. Here are some of them:

• When the liver cannot filter old blood cells, bilirubin builds up and causes yellowing of the eyes, or jaundice.
• Dry or grainy eyes are caused by vitamin A deficiency or issues with bile flow.
• One symptom of vitamin A deficiency is night blindness. Chronic liver disease patients often lack vitamin A, leading to eye-related problems.
• Cataracts or corneal clouding are caused by metabolic liver diseases such as Wilson's or galactosemia.
• Sudden vision loss is uncommon but possible in hepatic encephalopathy, where ammonia toxicity harms the brain regions responsible for vision.

How Does Liver Dysfunction Lead to Vision Problems?

Eye health is directly impacted by the liver's function in metabolism and detoxification. Here’s how liver damage can affect your eyes:

• Nutrient Processing: Vitamin A, necessary for the retina's functioning, is stored and released by the liver. Damage lowers vitamin A levels, which causes dry eyes and night blindness.
• Toxin Filtration: Ammonia and metals like copper can build up in a failing liver, harming the optic nerves or parts of the brain that control vision.
• Blood Flow Regulation: Liver disease can make it harder for blood to clot, which raises the possibility of retinal haemorrhages.

What Role Do Nutritional Deficiencies Play in Liver-Related Vision Issues?

Liver disease disrupts the absorption and storage of key nutrients, like the following:

• Vitamin A: Deficiency causes dry eyes, corneal ulcers, and night blindness. Chronic alcohol use exacerbates this by impairing vitamin A metabolism.
• Vitamin K: Poor synthesis due to liver damage leads to bleeding disorders, which may cause subconjunctival haemorrhages (red spots in the eyes).
• Zinc and Copper: Imbalances in these metals, common in Wilson’s disease, can deposit in the cornea, causing sunflower cataracts or Kayser-Fleischer rings.

Which Liver Diseases Are More Likely to Affect Vision?

Some liver conditions, like the following, have stronger ties to eye complications:

• Alcoholic Cirrhosis: This condition is linked to severe vitamin A deficiency, causing Bitot’s spots (white corneal patches) and corneal necrosis.
• Viral Hepatitis (B/C): It is associated with retinal vasculitis, dry eye syndrome (peripheral corneal ulcers).
• Autoimmune Hepatitis: This condition may trigger uveitis (eye inflammation) or peripheral ulcerative keratitis.
• Wilson’s Disease: This condition causes excessive copper accumulation, leading to Kayser-Fleischer rings (greenish corneal discolouration) and cataracts.
• Non-alcoholic Fatty Liver Disease (NAFLD): This condition is linked to diabetic retinopathy due to insulin resistance.

How Can Liver Disease Patients Protect Their Eye Health?

Here are some of the preventive measures to manage your eye health if you have liver disease:

• Regular eye checkups help detect early signs of nutrient deficiencies or optic nerve damage.
• Take vitamin A or K supplements under medical guidance.
• Include omega-3-rich foods (e.g., fish, flaxseed) in your diet to support tear production and retinal health.
• Limit alcohol and toxins. This helps reduce further liver damage and nutrient depletion.
• Manage underlying conditions like diabetes or hypertension to prevent secondary eye damage.

Liver disease can cause blurry vision through nutrient deficiencies, toxin buildup, and metabolic disruptions. Symptoms range from dry eyes and jaundice to sudden vision loss in severe cases. To preserve sight, you can opt for regular eye checkups, nutrient management, and controlling liver damage.

It is also advised to have health insurance to secure your health and finances during critical times. Star Health's general insurance plans offer extensive coverage for eye-related conditions and liver diseases. We also provide hassle-free claim settlements with reduced turnaround time across over 14,000 network hospitals in India.
