卫气少而寒气乘之也，元气微而饮食伤之也。外乘内伤，酿而成之也。父母以其纯阳耶，
故深冬不为裳；父母以其恶风那，故盛夏不解衣；父母以其数饥耶，故饲后强食之；父母以其

凉，饮而不至渴，食而不及饥。而小儿幽玄衔默，抱疾而不能自言，故外乘内伤，因循积渐，
酿而成疳也。渴而易饥，食而瘦，腹胀下利，作嘶嘶声；日远不治，遂生目病。其病生翳，睫
闭不能开，眵泪如糊，久而脓流，竟枯两目。何则？为阳气下走也，为阴气反上也。治法当如
阴阳应象大论曰∶清阳出上窍，浊阴出下窍；清阳发腠理，浊阴走五脏；清阳实四肢，浊阴归
六腑。各远其原，不反其常，是其治也。当作升阳降阴之剂，茯苓泻湿汤主之，升麻龙胆草饮

左寸脉洪数，心火炎上也，关弦而洪，肝火盛也。右寸脉关脉俱弦而洪，肝木挟相火之势，
而先侮所不胜
之金，而制己所胜之土也。尺脉微弱，肾水不升，而火在上。尺脉洪数，为相火邪火上炎，
挟肝木之邪而烁目也。
经曰∶目得血而能视。故血为目之主，血病则目病，血凝则目胀，血少则目涩，血热则目肿。
所以古人治目，惟取神庭、上星、囟会、前顶、百会。血之翳者，可使立退，痛者可使立已，
昧者可使立明，肿者可使立消。令人亦有去血之法，惟可施于暴热暴肿，又不宜以为法之常也。
何则？令人多是七情之郁火，气血之耗损，故去血太多，而目愈槁，无所滋荣，病益炽矣，所以

卫气虚弱而寒气侵袭，元气微弱而饮食损伤。外邪侵袭与内伤积滞相互交织，酝酿而成疾病。父母认为孩子纯阳之体，所以在深冬也不给孩子穿厚衣；父母认为孩子怕风，所以在盛夏也不让孩子脱去衣服；父母担心孩子饥饿，所以在喂奶后强行喂食；父母担心孩子口渴，所以在哺乳后又额外喂水。有些愚笨的父母，不仔细辨别孩子的寒热和饮食需求，导致孩子受寒却不保暖，天热却不凉爽，饮水却不知渴，进食却未觉饥。而小儿年幼无知，沉默寡言，身患疾病却无法自述，因此外邪侵袭、内伤积滞，日积月累，最终酿成疳积病。症状表现为口渴且容易饥饿，进食后反而消瘦，腹部胀满并伴有腹泻，喉咙发出嘶嘶声；若日久不治疗，就会引发眼疾。眼部病症表现为生翳，眼睑闭合无法睁开，眼屎泪水如糊状，时间久了脓液流出，最终双目枯盲。为什么呢？这是因为阳气下陷，阴气上逆所致。治疗方法应当遵循《阴阳应象大论》所说的：清阳之气出于上窍，浊阴之气出于下窍；清阳之气发散于腠理，浊阴之气走注于五脏；清阳之气充实四肢，浊阴之气归于六腑。使各归其位，不违背常态，这就是治疗原则。应当使用升阳降阴的方剂，以茯苓泻湿汤为主，或以升麻龙胆草饮子为主。这些药物并非专门针对眼部疾病，而是同时治疗上述几种证候。然而不可延误治疗，延误则病情危重。作为父母应当审慎对待。
左寸脉洪数，是心火炎上的表现；关脉弦而洪，是肝火旺盛的表现。右寸脉和关脉都呈现弦而洪的特征，这是肝木挟带相火的势头，先克制它不能胜克的肺金（所不胜），再制约它所胜的脾土（己所胜）。尺脉微弱，说明肾水不能上升，导致火气在上焦；尺脉洪数，说明相火和邪火上炎，挟带肝木的邪气灼伤眼睛。
经典论述说：眼睛得到血液的滋养才能视物。所以血是眼睛的主宰，血病则眼病，血凝滞则眼球胀痛，血不足则眼睛干涩，血热则眼睛红肿。所以古人治疗眼疾，只选取神庭、上星、囟会、前顶、百会等穴位进行放血疗法。对于血瘀引起的翳障，可以使它立即消退；疼痛可以使它立即停止；视力模糊可以使它立即明亮；肿胀可以使它立即消除。让人也有放血的方法，但只适用于突发热毒和急性肿胀的情况，不宜作为常规治疗方法。为什么呢？因为现代人多是七情郁结产生的火邪，以及气血的耗损，如果放血过多，眼睛会更加干枯，失去滋润荣养，病情会更加炽盛，导致长年不愈，最终失明。现在的医者治疗眼疾，只把活血凉血作为上策，并通过滋阴降火来收功。这大概是治疗眼疾的大纲，既没有损害，又必定能取得十全的效果，医者不可以不审慎研究。
Wei Qi (Defensive Qi) is deficient and invaded by Cold Pathogen; Yuan Qi (Original Qi) is weak and damaged by dietary irregularities. External invasion combined with internal injury brews into disease. Parents, considering the child to possess pure Yang, do not provide warm clothing in deep winter; parents, thinking the child dislikes wind, do not remove clothes in midsummer; parents, fearing hunger, force-feed after nursing; parents, fearing thirst, give extra fluids after breastfeeding. Some foolish parents fail to examine cold/heat and dietary needs properly: thus, cold does not lead to warming, heat does not lead to cooling, drinking does not reach thirst, eating does not reach satiety. Children are young and silent, suffering from illness but unable to speak of it. Thus, external invasion and internal injury accumulate gradually, brewing into Gan Syndrome (Pediatric Malnutrition). Symptoms include thirst and easy hunger, emaciation despite eating, abdominal distension with diarrhea, and a hissing sound in the throat. If untreated over time, eye diseases arise. The pathology involves the formation of nebulae (corneal opacities), eyelids closed and unable to open, discharge like paste, eventually flowing pus, leading to blindness in both eyes. Why? Because Yang Qi sinks downward and Yin Qi rebels upward. The treatment method should follow the "Treatise on Yin and Yang Corresponding to Phenomena": Clear Yang emerges from the upper orifices, Turbid Yin exits through the lower orifices; Clear Yang disperses through the Cou Li (interstices), Turbid Yin travels to the Zang Organs; Clear Yang fills the four limbs, Turbid Yin returns to the Fu Organs. Let each return to its origin, not reversing their normal state; this is the treatment principle. One should prepare decoctions that raise Yang and descend Yin, primarily using Fuling Xie Shi Tang (Poria Decoction to Drain Dampness) or Shengma Longdancao Yinzi (Ephedra and Gentian Decoction). These medicines are not exclusively for the eyes but also treat the aforementioned syndromes. However, do not delay treatment; delay leads to critical danger. Parents must be prudent.
The Left Cun pulse is surging and rapid, indicating Heart Fire flaming upward; the Guan pulse is wiry and surging, indicating Liver Fire excess. The Right Cun and Guan pulses are both wiry and surging; this indicates Liver Wood leveraging the momentum of Ministerial Fire to first insult Metal (the element it cannot overcome) and then control Earth (the element it overcomes). The Chi pulse is weak and faint, indicating Kidney Water failing to ascend, leaving Fire above. The Chi pulse is surging and rapid, indicating Ministerial Fire and Evil Fire flaming upward, carrying the pathogenic factor of Liver Wood to scorch the eyes.
The Classics state: "The eyes can see when they receive Blood." Therefore, Blood is the master of the eyes; Blood disease causes eye disease; Blood coagulation causes eye swelling/distension; Blood deficiency causes dry eyes; Blood Heat causes red and swollen eyes. Thus, ancient physicians treated eye diseases only by selecting Shen Ting, Shangxing, Xinhui, Qian Ding, and Baihui points for bloodletting. For nebulae caused by Blood stasis, they could make them recede immediately; for pain, stop it immediately; for dim vision, restore clarity immediately; for swelling, eliminate it immediately. There is a method of removing Blood, but it is only applicable to sudden Heat toxicity and acute swelling, and should not be used as a routine method. Why? Because modern people often suffer from Fire generated by emotional stagnation (Seven Emotions) and depletion of Qi and Blood. Excessive bloodletting causes the eyes to become more withered, losing nourishment and flourishing, making the disease more intense, leading to chronic non-healing and eventual blindness. Contemporary physicians treating eye diseases should take invigorating Blood and cooling Blood as the supreme strategy, achieving results by nourishing Yin and descending Fire. This is the general outline for treating eye diseases; it causes no harm and guarantees complete success. Physicians must study this carefully.
