目，肝之外候也。肝藏血，足厥阴也，其脉起足大趾之聚毛，入连于目系。其经脉之血
气虚，而为风热所乘，故血脉生于白睛之上，谓之飞血。
目黑者，肝虚故也。目是脏腑之精华，肝之外候，而肝藏血。腑脏虚损，血气不足，故
肝虚不能荣于目，致精彩不分明，故目黑。
五脏六腑之精华，皆上注于目，目为肝之外候。肝藏血，血气不足，则肝虚，致受风邪
，风邪搏于精气，故精气聚生于白睛之上，绕于黑睛之际，精彩昏浊，黑白不明审，谓之止
目者，是风气客于睑 之间，与血气津液相搏，使目 痒而泪出，目 恒湿，故
谓之 目。
目，是腑脏之精华，肝之外候。夫目，上液之道，腑脏有热，气熏于肝，冲发于目 睑
，使液道热涩，滞结成眵 也。
目，是腑脏血气之精华，肝之外候，然则五脏六腑之血气，皆上荣于目也。若血气虚，
则肤腠开而受风，风客于睑肤之间，所以其皮缓纵，垂覆于目，则不能开，世呼为睢目，亦
目者，腑脏之精华，宗脉之所聚，肝之外候也。风邪停饮在于脏腑，侵于肝气，上冲于
眼，则生翳鄣、管珠、 肉。其经络有偏虚者，翳鄣则偏覆一瞳子，故偏不见物，谓之眇目
肥目者，白睛上生点注，或如浮萍，或如榆荚，有如胡粉色者，有作青黑色者，似羹上
脂，致令目暗，世呼为肥目。五脏六腑之精华，皆上注于目，为肝之外候。宗脉所聚，上液
之道。此由腑脏气虚，精液为邪所搏，变化而生也。
The eyes are the external manifestation of the Liver. The Liver stores Blood and belongs to the Foot Jueyin Meridian (Zu Jue Yin Jin Mai). Its meridian originates from the pubic hair on the big toe and ascends to connect with the eye system. If the Qi and Blood in this meridian are deficient, and are invaded by Wind-Heat pathogenic factors, blood vessels may grow upon the sclera (Bai Jing), which is termed "Fei Xue" (Flying Blood).
Darkening of the eyes is due to Liver deficiency. The eyes are the essence of the Zang-Fu organs and the external manifestation of the Liver, which stores Blood. When the Zang-Fu organs are damaged and Qi and Blood are insufficient, the deficient Liver fails to nourish the eyes, resulting in a lack of luster and clarity, thus causing the eyes to appear dark.
The essence of the Five Zang and Six Fu organs all ascends to pour into the eyes; the eyes are the external manifestation of the Liver. The Liver stores Blood. If Qi and Blood are insufficient, Liver deficiency occurs, making it susceptible to Wind pathogenic factors. The Wind pathogen clashes with the essential Qi, causing the essence to gather and form upon the sclera, surrounding the margin of the cornea (Hei Jing). This results in turbid vision and indistinct boundaries between the white and black parts of the eye, referred to as "Zhi" (a specific ocular condition described in the text).
Itching and tearing of the eyes occur because Wind pathogen lodges between the eyelids, clashing with Qi, Blood, and body fluids. This causes the eyes to itch and tear, keeping the eyelids constantly moist, hence the condition is associated with excessive tearing.
Discharge (Chi) in the eyes arises because the eyes are the essence of the Zang-Fu organs and the external manifestation of the Liver. The eyes serve as the pathway for upper-body fluids. If there is Heat in the Zang-Fu organs, the Qi steams upward to the Liver and rushes to the eyelids, causing the fluid pathway to become hot and obstructed. Stagnation leads to the formation of discharge (eye boogers).
The eyes are the essence of the Zang-Fu Qi and Blood and the external manifestation of the Liver; indeed, the Qi and Blood of the Five Zang and Six Fu organs all ascend to nourish the eyes. If Qi and Blood are deficient, the skin pores open, allowing Wind pathogen to invade. The Wind lodges between the eyelid skin, causing the skin to become lax and sagging, covering the eyes so they cannot open. This is popularly called "Sui Mu" (Ptosis/Drooping Eyelid).
The eyes are the gathering place of the essence of the Zang-Fu organs and the convergence of the Zong Mai (Great Vessels), serving as the external manifestation of the Liver. If Wind pathogen and retained fluid exist within the Zang-Fu organs, invading the Liver Qi and rushing upward to the eyes, conditions such as Yi Zhang (ocular membranes/cataracts), Guan Zhu (corneal opacity/pupil distortion), and Ru Rou (Pterygium) may develop. If there is unilateral deficiency in the meridians, the occlusion covers one pupil asymmetrically, causing monocular blindness or visual field defects, termed "Miao Mu".
La Mu (Wax Eye) refers to a condition where fly larvae cause ulcers in the eye, hence the name.
Fei Mu (Fatty Eye) is characterized by spots growing on the sclera, resembling floating duckweed, elm seeds, whitewash powder, or appearing green-black like grease on soup surface. This leads to dim vision and is popularly called "Fei Mu". The essence of the Five Zang and Six Fu organs ascends to the eyes as the Liver's external manifestation, the convergence of Zong Mai, and the pathway for upper fluids. This condition arises from deficiency of Zang-Fu Qi, where body fluids are clashed by pathogenic factors, transforming into disease.
