The Eyes and the Liver

Chinese medicine says the Liver opens into the eyes, yet also says the essence of all five organs pours into them. Western medicine finds liver and eye meeting in vitamin A and in the yellow of the sclera when the liver fails. This page sets the two views side by side.

  • In Chinese medicine the eyes are the opening of the Liver, and when Liver qi is in harmony the eyes can tell the five colours apart.
  • The Lingshu chapter Dahuo Lun says the essence of the five zang and six fu all pours into the eyes, so the eyes belong to more than the Liver alone.
  • In Western medicine the liver stores most of the body vitamin A, which the retina needs to see in dim light.
  • Jaundice from liver disease shows first in the whites of the eyes.

The eyes in Chinese medicine

The Lingshu chapter Maidu says that Liver qi reaches the eyes, and when the Liver is in harmony the eyes can distinguish the five colours. That is the root of the saying that the Liver opens into the eyes. Yet the same Inner Classic, in the chapter Dahuo Lun, says the essence of the five zang and six fu all pours into the eyes to form their essence, and then assigns each part of the eye to an organ, the iris to the Liver, the white to the Lung, the canthi to the Heart, the lids to the Spleen and the pupil to the Kidney. The later doctrine of the five wheels grew from that passage.

The qi of the Liver communicates with the eyes. When the Liver is in harmony, the eyes can distinguish the five colours.Yellow Emperor Inner Classic, Lingshu, chapter 17 Maidu

So dry, dim or blurred eyes make Chinese medicine think of Liver blood deficiency, red, swollen or light sensitive eyes of Liver fire, and yellow eyes of damp heat in the Liver and Gallbladder. Each of these names a pattern, not an anatomical diagnosis.

The eyes in Western medicine

The eye is an organ of the nervous system, and the retina is a piece of brain pushed outward in the embryo. The liver does not control the eye, but it touches it in three places. The liver stores about nine tenths of the body vitamin A in its stellate cells, and lack of it brings night blindness and dry cornea. When the liver fails, bilirubin rises and the whites turn yellow before the skin does. In Wilson disease copper builds up in the liver and then settles at the edge of the cornea as the Kayser Fleischer ring.

Questions and answers

Do blurred eyes mean a weak liver?

In Chinese medicine blurred eyes may be Liver blood deficiency, but also Kidney essence decline or Spleen qi weakness. In Western medicine blurred vision has dozens of causes from refractive error to cataract and needs an eye examination. This page is for reference only.

Why does Chinese medicine treat the eyes through the Liver?

Because the Liver channel joins the vessels of the eye according to the Lingshu chapter Jingmai, and because the Liver stores blood, and when blood is ample the eyes are bright. That is reasoning within the system of Chinese medicine, not a physiological mechanism in the Western sense.
