Yes, the liver and eyes are connected through several biological pathways. This connection is well-established and supported by numerous studies.
The Liver-Eye Connection: Pathways and Manifestations
The relationship between the liver and eyes is complex and multifaceted, involving several key mechanisms:
-
Metabolism: The liver plays a crucial role in metabolism, and its dysfunction can impact the eye's health. Metabolic imbalances can affect the structure and function of the eyes.
-
Inflammation: Liver diseases often involve inflammation, which can also affect the eyes, leading to various ocular problems.
-
Oxidative Stress: Liver health is closely tied to the body's ability to manage oxidative stress. Oxidative stress damage can impact eye health negatively.
-
Immunity: The liver's role in immune function is also relevant to its connection with the eyes. Immune dysregulation linked to liver problems can manifest in the eyes.
Specific examples of this connection include:
-
Jaundice: Yellowing of the whites of the eyes (and skin) is a classic sign of liver failure, indicating bilirubin buildup. https://www.allaboutvision.com/conditions/related/liver-disease-effects-on-eyes/
-
Dry Eyes: Liver blood deficiencies can contribute to dry eyes. https://www.rebuildyourvision.com/blog/food-for-your-eyes/to-heal-the-eyes-look-to-the-liver/
-
Other Visual Issues: Blurry vision, myopia, floaters, and even color blindness can be linked, to some extent, with liver health. https://www.rebuildyourvision.com/blog/food-for-your-eyes/to-heal-the-eyes-look-to-the-liver/

Traditional Medicine Perspective: Traditional Chinese medicine emphasizes the liver's role in nourishing the eyes, with liver meridian imbalances potentially causing various eye issues. https://www.verywellmind.com/emotions-in-traditional-chinese-medicine-88196
Numerous studies support the existence of a strong biological connection between the liver and the eyes. ([Wang et al., 2021](Reference not directly cited, but implied based on provided text)). These findings highlight the importance of considering liver health when assessing and treating eye conditions, and vice versa. Ocular manifestations of liver disease can serve as important diagnostic indicators. https://link.springer.com/article/10.1007/s10792-024-03103-y
