眼无障翳，而不见物，谓之青盲。此由小儿脏内有停饮而无热，但有饮水积渍于肝也。
目是五脏之精华，肝之外候也。肝气通于目，为停饮所渍，脏气不宣和，精华不明审，故不
赤痛，亦无障翳，而不见物，故名青盲也。
人有昼而睛明，至暝便不见物，谓之雀目。言其如鸟雀，瞑便无所见也。
风邪客于睑 之间，与血气相搏，挟热即生疮，浸渍缘目，赤而有汁，时瘥时发。世云
小儿初生之时，洗浴儿不净，使秽露浸渍眼睑睫 ，后遇风邪，发即目赤烂生疮，喜难瘥，
瘥后还发成疹，世人谓之胎赤。
小儿经脉血气有热，喜令鼻衄。夫血之随气，循行经脉，通游腑脏。若冷热调和，行根据
其常度，无有壅滞，亦不流溢也。血性得寒即凝涩结聚，得热即流散妄行。小儿热盛者，热
乘于血，血随气发，溢于鼻者，谓之鼻衄。凡人血虚受热，即血失其常度，发溢漫行，乃至
发于七窍，谓之大衄也。
鼻之状，鼻下两边赤，发时微有疮而痒是也。亦名赤鼻，亦名疳鼻。然鼻是肺气

肺主气而通于鼻，而气为阳，诸阳之气，上荣头面。若气虚受风冷，风冷客于头脑，即
其气不和，冷气停滞，搏于津液，脓涕结聚，即鼻不闻香臭，谓之 鼻。
The eyes have no opacities (membranous growths on the cornea that obscure vision), yet the person cannot see; this is called Qingmang (Green Blindness). This condition arises because there is retained fluid (pathological accumulation of body fluids due to impaired metabolism) within the internal organs of the child, without heat pathogens, but rather due to drinking water accumulating and soaking into the Liver.
The eyes are the essence of the Five Zang Organs and serve as the external manifestation of the Liver. The Qi of the Liver connects to the eyes. When soaked by retained fluid, the organ's Qi fails to circulate smoothly and harmoniously, causing the essence to lack clarity and discernment. Consequently, the eyes are neither red nor painful, nor do they present with opacities, yet vision is lost; hence it is named Qingmang.
Some individuals have clear vision during the day but lose sight at dusk; this is called Que Mu (Sparrow Eye/Night Blindness). It is so named because, like sparrows, they can see nothing when it becomes dark.
Wind pathogens lodge between the eyelids and contend with Blood and Qi. If accompanied by Heat, sores may arise, spreading along the eye margins, causing redness and discharge, with symptoms that remit and recur intermittently. It is said in popular belief that when newborns are bathed improperly, filth and dew soak the eyelids and lashes. Later, upon exposure to Wind pathogens, the condition manifests as red, rotting eyes with sores. It tends to be difficult to cure and often recurs after healing, forming rashes; people call this Tai Chi (Fetal Redness).
Children often suffer from heat in their meridians and Blood-Qi, predisposing them to Bi Xu (Nosebleed). Blood follows Qi, circulating through the meridians and flowing through the Fu and Zang organs. If Cold and Heat are balanced, circulation follows its normal course without stagnation or extravasation. Blood congeals and clots when exposed to Cold, but flows and wanders recklessly when exposed to Heat. In cases where children have excessive Heat, the Heat attacks the Blood, which then moves with Qi and overflows from the nose; this is termed Bi Xu. In adults, if Blood deficiency is compounded by Heat, Blood loses its normal regulation, disperses and wanders, potentially erupting from the seven orifices; this is called Da Nu (Major Hemorrhage).
The presentation of nasal conditions involves redness on both sides below the nose, with mild sores and itching upon flare-ups. This is also known as Chi Bi (Red Nose) or Gan Bi (Malnutrition Nose). The nose is the passage for Lung Qi. The Lung governs the skin and hair. If Lung Qi is disharmonious, Wind pathogens lodge in the skin and hair, subsequently affecting Blood and Qi. Pathogens enter and stay in areas of deficiency within the Blood and Qi. When they settle on both sides of the nose and contend with Blood and Qi to form sores, it is referred to as [missing character] Bi (Nasal Sores).
The Lungs govern Qi and connect to the nose. Qi belongs to Yang, and all Yang Qi ascends to nourish the head and face. If Qi is deficient and exposed to Wind-Cold, the pathogen lodges in the head, causing Qi disharmony. Cold Qi stagnates and contends with Body Fluids, leading to the accumulation of purulent mucus. This results in the inability to smell odors, a condition referred to as [missing character] Bi (likely Bi Yuan/Nasal Sinusitis).
