10 Things Your Eyes Reveal About Your Liver
The eyes are often called the windows to the soul, but they can also offer a revealing glimpse into the health of your liver. This vital organ, responsible for a multitude of functions ranging from detoxification and metabolism to the synthesis of essential proteins and the regulation of blood clotting, can manifest signs of distress in ways that are visible to the careful observer. Among the most telling of these signals are changes in the eyes — in their color, their comfort, their appearance, and their function.
The liver-eye connection is well-documented in medical literature. A landmark review published in the Journal of Translational Medicine describes the liver and eyes as engaged in a form of “inter-organ communication,” noting that dysfunctional liver function is frequently accompanied by pathological changes in the eyes [1]. Similarly, a 2024 review in International Ophthalmology concluded that ocular signs of liver disease can serve as “an important diagnostic aid,” sometimes allowing clinicians to identify liver pathology before other symptoms emerge [2].
This article explores ten important eye-related signs that may indicate an underlying liver condition, drawing on peer-reviewed research and clinical findings to provide a comprehensive and accessible overview.

1. Jaundice: The Yellowing of the Eyes
One of the most recognizable signs of liver trouble is jaundice, a condition that causes the whites of the eyes (the sclera) and the skin to turn a characteristic shade of yellow [3]. Medically, the yellowing of the sclera is referred to as scleral icterus, and it is caused by a buildup of bilirubin — a yellow-orange pigment produced during the normal breakdown of red blood cells. Under healthy conditions, the liver efficiently processes and excretes bilirubin through bile. However, when the liver is damaged or diseased, this process is disrupted, and bilirubin accumulates in the bloodstream and deposits in tissues, including the delicate membranes of the eye [4].
Jaundice is a hallmark symptom of a wide range of liver diseases, including viral hepatitis, alcoholic liver disease, primary biliary cholangitis, and liver cancer. It can also occur with gallstones, pancreatitis, and sickle cell disease. Importantly, the eyes often show jaundice before the skin does, making scleral icterus one of the earliest and most reliable visual indicators of elevated bilirubin levels [3, 5]. A blood test measuring serum bilirubin can confirm the diagnosis and help identify the underlying cause.
2. Xanthelasma: Cholesterol Deposits on the Eyelids
Yellowish, soft, slightly raised plaques on the eyelids or around the eyes — a condition known as xanthelasma palpebrarum — are deposits of cholesterol-rich material beneath the skin [6]. While xanthelasma is not dangerous in itself, its presence can be a visible warning that the liver is struggling to regulate lipid metabolism. The liver is the primary organ responsible for producing, processing, and clearing cholesterol from the bloodstream. When liver function is impaired — as in fatty liver disease, primary biliary cholangitis, or other cholestatic conditions — cholesterol and other lipids can accumulate in the blood and deposit in soft tissues, including the skin around the eyes [7].
Xanthelasma is particularly associated with elevated levels of low-density lipoprotein (LDL) cholesterol and is often seen in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD). Although the deposits themselves are painless and cosmetically removable, their appearance should prompt a thorough evaluation of both lipid levels and liver function [6, 7].
3. Kayser-Fleischer Rings: Copper’s Telltale Mark
Among the most striking and diagnostically significant eye signs in all of medicine are Kayser-Fleischer (K-F) rings — golden-brown or greenish-gold bands that appear at the outer rim of the cornea [8]. These rings are caused by the deposition of excess copper in Descemet’s membrane, a thin layer within the cornea, and they are pathognomonic for Wilson’s disease, a rare autosomal recessive genetic disorder of copper metabolism [9].
In Wilson’s disease, the liver is unable to properly excrete copper into bile, leading to its progressive accumulation in the liver, brain, kidneys, and eyes. Over time, copper toxicity causes severe hepatic damage, including cirrhosis and liver failure. K-F rings are present in virtually all patients with Wilson’s disease who have neurological involvement, and in a significant proportion of those with hepatic-only disease. Detection typically requires a slit-lamp examination by an ophthalmologist, as the rings may not be visible to the naked eye in early stages [8, 9]. The identification of K-F rings is a critical step in the diagnostic workup for Wilson’s disease and can prompt life-saving treatment with copper-chelating agents.
4. Dry and Irritated Eyes: A Sign of Autoimmune Liver Disease
Persistent dryness, burning, grittiness, and irritation in the eyes — collectively known as dry eye syndrome or keratoconjunctivitis sicca — can be a manifestation of certain autoimmune liver diseases. Primary biliary cholangitis (PBC), a chronic autoimmune condition in which the immune system attacks and destroys the small bile ducts within the liver, is frequently associated with Sjögren’s syndrome, another autoimmune disorder that targets the glands responsible for producing tears and saliva [10, 11].
Research has shown that liver cirrhosis and gallstone disease are independent risk factors for dry eye disease, with cirrhosis carrying an odds ratio of 3.38 for developing the condition [1]. Autoimmune hepatitis has similarly been linked to defective tear secretion and tear film instability [2]. Hepatitis C infection is also associated with dry eye, partly through its tendency to trigger Sjögren’s-like sicca syndrome and keratoconjunctivitis sicca [12]. For patients who experience persistent dry eyes alongside fatigue, abdominal discomfort, or other systemic symptoms, an evaluation of liver function is warranted.
5. Night Blindness: When the Liver Fails to Store Vitamin A
Night blindness (nyctalopia) — the inability to see clearly in low-light conditions — is one of the earliest and most clinically significant signs of vitamin A deficiency, and liver disease is a major cause of this deficiency [13]. The liver is the body’s primary storage site for vitamin A, holding approximately 80–90% of the body’s total reserves. In patients with chronic liver disease, cirrhosis, or alcohol-related liver damage, the liver’s capacity to store and release vitamin A is severely compromised, leading to deficiency even when dietary intake appears adequate [14].
Vitamin A is essential for the synthesis of rhodopsin, a light-sensitive pigment in the rod cells of the retina that enables vision in dim light. When vitamin A levels fall, rhodopsin production declines, and night vision deteriorates. If the deficiency is not corrected, it can progress to a broader condition called xerophthalmia, which encompasses a spectrum of ocular complications including corneal drying (xerosis), the formation of foamy white patches on the conjunctiva (Bitot spots), corneal ulceration (keratomalacia), and ultimately permanent vision loss [15, 16]. Early recognition and supplementation can reverse night blindness, but advanced corneal damage may be irreversible.
6. Retinal Changes and Diabetic Retinopathy
The retina — the light-sensitive tissue lining the back of the eye — can be affected by liver disease through several interconnected pathways. One of the most important is the liver’s role in blood glucose regulation. When the liver is damaged, it can develop insulin resistance and impair glucose homeostasis, increasing the risk of type 2 diabetes. In patients who already have diabetes, liver dysfunction can make glycemic control more difficult, accelerating the development of diabetic retinopathy, a condition in which the blood vessels of the retina become damaged, leak, or proliferate abnormally [17, 18].
Research has established a significant association between non-alcoholic fatty liver disease (NAFLD) and diabetic retinopathy, with NAFLD patients showing an elevated odds ratio for proliferative or laser-treated retinopathy [1]. A 2024 study published in Medicina further noted that dysregulation of angiopoietin-like protein 4 (ANGPTL4) in liver disease may contribute to increased vascular permeability and retinal edema [19]. Additionally, when a severely damaged liver fails to clear ammonia from the bloodstream, this toxic compound can accumulate and damage the visual cortex, causing a form of vision loss known as cortical visual impairment [17].
7. Itchy Eyes: The Itch of Bile Accumulation
Pruritus — intense, persistent itching — is one of the most distressing symptoms of cholestatic liver diseases, conditions in which the normal flow of bile from the liver is obstructed or impaired. While this itching most commonly affects the palms, soles, and skin, it can also manifest in the eyes, causing significant discomfort and irritation [20]. The precise mechanism of cholestatic pruritus is not fully understood, but the accumulation of bile salts and other pruritogens in the bloodstream is believed to play a central role, as these compounds stimulate itch-sensing nerve fibers throughout the body [21].
Conditions that commonly cause cholestatic pruritus include primary biliary cholangitis, primary sclerosing cholangitis, intrahepatic cholestasis of pregnancy, and drug-induced cholestasis. When itchy eyes occur alongside dark urine, pale stools, jaundice, or fatigue, they may be part of a broader cholestatic syndrome that warrants prompt medical evaluation. Unlike allergy-related itchy eyes, cholestatic ocular pruritus typically does not respond to antihistamines and requires treatment of the underlying liver condition.
8. Eye Floaters: A Subtle Signal Worth Noting
Eye floaters — the small, dark specks, threads, or cobweb-like shapes that drift across the visual field — are a common and usually benign phenomenon caused by changes in the vitreous humor, the gel-like substance that fills the interior of the eye. However, a sudden increase in floaters, particularly when accompanied by flashes of light or a shadow across the visual field, can indicate more serious pathology. In the context of liver disease, floaters may be associated with retinal vasculitis (inflammation of the retinal blood vessels), which has been documented in patients with hepatitis C infection [12].
In Traditional Chinese Medicine (TCM), the liver is considered to “open into the eyes,” and liver blood deficiency is classically associated with visual disturbances including floaters, blurred vision, and dry eyes [22, 23]. While this framework differs from Western biomedicine, it reflects a long-standing clinical observation of the liver-eye relationship that modern research is beginning to corroborate. Patients with liver disease who notice a new onset or worsening of floaters should seek an ophthalmological evaluation to rule out retinal pathology.
9. Subconjunctival Hemorrhage: When the Liver Cannot Clot
A subconjunctival hemorrhage is a bright red patch on the white of the eye caused by the rupture of a small blood vessel beneath the conjunctiva. While isolated, single-episode subconjunctival hemorrhages are usually harmless and self-resolving, spontaneous, recurrent, or bilateral occurrences can signal an underlying bleeding disorder, including those caused by liver disease [24]. The liver is responsible for synthesizing the majority of the body’s coagulation factors — the proteins that enable blood to clot properly. In patients with severe hepatic disease, cirrhosis, or acute liver failure, the production of these clotting factors is significantly reduced, leading to a coagulopathy that predisposes to bleeding throughout the body [25].
This bleeding tendency can manifest as easy bruising, prolonged bleeding from cuts, nosebleeds, bleeding gums, and, in the eyes, spontaneous subconjunctival hemorrhages. A case series published in a gastroenterology journal documented spontaneous subconjunctival and retinal hemorrhages in patients with acute-on-chronic liver failure, attributing them to coagulopathy and thrombocytopenia [25]. The presence of unexplained or recurrent eye bleeding should therefore prompt an assessment of liver function and coagulation status.
10. Uveitis and Retinal Vasculitis: Inflammation from Within
Uveitis — inflammation of the uvea, the middle layer of the eye comprising the iris, ciliary body, and choroid — and retinal vasculitis — inflammation of the blood vessels supplying the retina — are serious ocular conditions that have been linked to several forms of liver disease, particularly viral hepatitis and autoimmune hepatitis [26, 27]. The connection is primarily immunological: the systemic inflammation and aberrant immune activation associated with these liver conditions can trigger inflammatory responses in the eye, where the immune system attacks ocular tissues.
Studies have shown that patients with hepatitis B and C virus infections have a significantly elevated risk of developing uveitis, with hepatitis B/C co-infection carrying the highest risk [26]. Retinal vasculitis, presenting with blurred vision, floaters, and visual field loss, has been documented as a complication of hepatitis C-related cryoglobulinemia, a condition in which abnormal proteins precipitate in blood vessels [12]. Autoimmune hepatitis has been associated with peripheral ulcerative keratitis and uveitis, and in some reported cases, uveitis was the presenting symptom that led to the diagnosis of the underlying liver disease [27, 28]. These findings underscore the importance of a thorough systemic evaluation in any patient presenting with unexplained intraocular inflammation.
Conclusion
The intricate relationship between the liver and the eyes reflects the liver’s central role in systemic physiology. As the body’s primary metabolic, detoxifying, and synthetic organ, the liver’s dysfunction reverberates across multiple organ systems — and the eyes, with their rich vascular supply, metabolic demands, and immunological sensitivity, are among the first to show the signs. From the unmistakable yellowing of jaundice to the subtle golden rings of Wilson’s disease, from the dryness of autoimmune liver conditions to the bleeding tendency of hepatic coagulopathy, the eyes offer a remarkable window into hepatic health.
Awareness of these ten signs is valuable both for patients and clinicians. While none of these eye findings should be interpreted in isolation — each has multiple potential causes — their presence, particularly in combination or alongside other systemic symptoms, warrants prompt medical evaluation. Regular eye examinations, combined with routine liver function testing in at-risk individuals, represent a powerful strategy for the early detection and management of liver disease. As research into the liver-eye axis continues to advance, the eyes may increasingly serve not merely as a diagnostic window, but as a tool for monitoring the progression and treatment response of hepatic conditions.
