经云∶五脏六腑之精华，皆上注于目。目者肝之窍也，肝与胆为表里，肝液胆汁充足，
目乃能远视，故无论外感内症，皆与肝胆有关。六淫之邪，风火与燥气居多，内起之症，肝胆与心肾为多。
白睛属肺曰气轮，乌球属肝曰风轮。大小 心曰火轮，上下胞脾曰肉轮。瞳神属肾曰水
轮，五脏五轮多肝经。目得血养视乃明，肝有风热目病生。

古籍记载：五脏六腑的精微物质，都向上灌注于眼睛。眼睛是肝的窍道，肝与胆互为表里，肝液和胆汁充足，眼睛才能看清远处的事物，所以无论是外感病还是内伤病，都与肝胆有关。六淫邪气中，风、火和燥气居多；体内产生的病症，多与肝胆和心肾有关。
白睛属于肺，称为气轮；黑眼球（乌球）属于肝，称为风轮；内外眼角的心部区域称为火轮；上下眼睑属于脾，称为肉轮；瞳孔属于肾，称为水轮。五脏对应的五轮大多与肝经有关。眼睛得到血液的滋养视力才清明，肝有风热则眼病发生。

陈参说：治疗外感引起的眼病，必须有恶寒发热、头痛鼻塞、骨节疼痛、脉象紧数浮洪的表现，才可以采用清散的方法。内在固结的病症，如肝胆风热盛，应当散热除风；如果是肾经水亏火衰，应当壮水益火。如果阴血虽然亏损，但风热未尽，则应当审察病情的缓急，综合参酌进行治疗。
The ancient texts state: The essence of the five zang organs and six fu organs all ascend to nourish the eyes. The eyes are the orifice of the Liver (Gan). The Liver and Gallbladder (Dan) have an exterior-interior relationship. When the liver fluid and bile juice are sufficient, the eyes can see distant objects clearly. Therefore, whether it is an external contraction disease or an internal syndrome, it is related to the Liver and Gallbladder. Among the pathogenic factors of the Six Excesses (Liu Yin), wind, fire, and dryness are predominant; among internally generated syndromes, they are mostly related to the Liver, Gallbladder, Heart, and Kidney.
The white part of the eye belongs to the Lung (Fei) and is called the Qi Wheel (Qi Lun); the black pupil (Wu Qiu) belongs to the Liver and is called the Wind Wheel (Feng Lun); the inner and outer canthi belong to the Heart (Xin) and are called the Fire Wheel (Huo Lun); the upper and lower eyelids belong to the Spleen (Pi) and are called the Flesh Wheel (Rou Lun); the pupil belongs to the Kidney (Shen) and is called the Water Wheel (Shui Lun). The Five Wheels corresponding to the five zang organs are mostly related to the Liver Meridian. The eyes need blood nourishment for clear vision; if there is wind-heat in the Liver, eye diseases arise.

Chen Can stated: For treating external contractions, there must be symptoms of chills and fever, headache, nasal congestion, bone pain, and a pulse that is tight, rapid, floating, or surging before clearing and dispersing methods can be used. For internal consolidation, such as excess wind-heat in the Liver and Gallbladder, one should dissipate heat and remove wind; if it is water deficiency and fire decline in the Kidney meridian, one should strengthen water and benefit fire. If yin-blood is deficient but wind-heat is not yet exhausted, one must examine the urgency of the condition and treat comprehensively by combining approaches.
