此症谓平素别无他病，外不伤轮廓，而内弗损瞳神。倏然盲而不见也。其故有三∶曰阴孤、曰阳寡、曰神离。

宝镜般晶莹明亮，号称能照见妖魔的眼睛，如今悬在空中，谁还能对着它轻轻呵气（以测试其清晰度）？希望从今以后好好珍藏爱护，免得因昏花朦胧而耗费精力去清洗打磨。
这种病症表现为眼睛红痛、眼屎和流泪都很少或没有，但黑睛（角膜/虹膜区域）如同被浑浊的烟雾笼罩，色泽晦暗无光。严重的就像对着镜子呵气一样，无法映照出人的面目。从侧面看过去，才能隐约看到一点瞳孔（金井）。虽然患者自视近处尚能看见物体，但这与隔着丝帛观看没有什么两样。究其病源，是因为热症误用寒凉药物，交叉损伤了脂膜，加之吝惜用药，精神劳损日久，又不注意调养休息所致。这分明是外障眼病，但风轮（黑睛）表面光滑，没有实质性的翳膜可以去除，所以称为“气翳”。这是最难治疗的病症。如果是突发疾病后翳膜消退出现类似情况，那是元气尚未恢复，不属于此论断范围。药物可参照医案进行增减，十例中能稳妥治愈十例。
表兄余兆文的次子，十六岁，在长夏季节患风热导致的红肿眼病。医生治疗后病情虽愈，但双眼留下了气翳，样子像死人的眼睛，令人害怕直视。兄长亲自前往南丰求医，我因为是祖母的至亲，冒着酷暑同行。诊察发现症状确实怪异，切脉也显得杂乱无章。询问患者的喜好和舒适感，他说腹部胀满不想吃东西，只是口渴需要饮水，小便多。询问视力情况，他说白天看起来像黑夜一样。由此领悟到是医药使用过度，邪气虽然去除，但脏腑之气大受损伤，于是使用附子理中汤（Aconite and Magnolia Root Decoction）加入当归（Angelicae Sinensis Radix）、白术（Atractylodis Macrocephalae Rhizoma），傍晚又配合左右合归方服用。第二天，风轮下方边缘如新月般清晰明朗，超过平常。于是根据此法继续进药，每天视力都打开一线。恰好十五天后完全清澈。后来又有一个人，突然患上气障，白天服用补中益气汤（Tonify the Middle and Augment the Qi Decoction），晚上服用八味地黄丸（Eight-Ingredient Rehmannia Pill）交替投药十几天，也痊愈了。
眼科中没有这类病症的记录，也未必会使用这些药物，学习者若能触类旁通，或许能得到我的真传。
银海双涵（指双眼）如夜明珠般照亮夜晚，轻易地丧失视力让人漫不经心地惊讶怀疑，这不是鬼神作祟妖怪为害，实际上是气机潜行推动，血液暂时分离所致。患者众多，离去的人稀少，那些多愁善病的人不需要特别医治，就像邯郸梦醒黄粱饭熟一样自然。说给纯阳祖师听了也会皱眉。
这种病症说的是平时没有其他疾病，外部不伤及轮廓，内部也不损伤瞳神，突然失明看不见东西。其原因有三条：叫做阴孤、阳寡、神离。损伤阳气的，大多因为六欲；损伤阴气的，大多因为七情；损伤神明的，兼有情欲两者都有。有少年时知识未开化，年老时世事已终结，忽然得此病，不在三者之列，这属于关格病。什么是关格呢？就是阳脉不和，气停留在腑，导致阳气太盛，阴气不能在上部相互荣养，所以叫“关”。凡是外感病，是气机变动，邪气随气进入，而上窍不通利的，都属于关的范畴。阴脉不和，血停留在脏，导致阴气太盛，阳气不能在下部相互护卫，所以叫“格”。凡是杂病由血产生，邪气随血外出，而下窍不通利的，都属于格的范畴。阴阳两盛，阴中没有阳，阳中没有阴，阴阳相互分离，导致营卫阻塞，气血不能相互营运，这是脏腑同时受到邪气侵袭，所以叫关格。总而言之，不是头风痰火、元气虚弱水液不足的人不会患此病。如果能保养得当并按时药物治疗，不久就能自愈，否则就会变成顽固性疾病。这种病症发生最快且奇异，人们都怀疑是鬼神作祸，先找巫师后找医生，不知道紧急治疗可以恢复，拖延则性格定势，药物就无效了。鬼神能做什么呢？僧道又能做什么呢？
这种病症突然发作，无论属于阴、阳、神还是关格，立即煎煮独参汤（Single Ginseng Decoction）几钱，趁热频繁服用。然后裁定其他药品，只补不泻，或许能保全无事。有人问其中的道理，回答说：血是气的守备，气是血的护卫，二者相伴而不分离。所以神明安住于其居所而眼睛明亮。现在突然失明，大概是气先被邪气所中，气既然受了邪，必然传给血，这就是所谓的气病血也病。如果再有一次失脱，那么气就成为孤阳，犹如烈火；血成为独阴，几乎等于寒水。此时有形之血不能快速生成，极其微弱的之气应当急需顾护。因此使用甘温的人参来固护元气，这是在权衡轻重缓急。经书说：血脱益气，阳生阴长，说的就是这个道理。敢问其次的方法是什么？说是归脾汤（Guipi Decoction）加六一散（Liu Yi San），如果家境贫寒没有办法，用它来搪塞责任也可以了。至于那射中靶心的高明医术，细微的人参功效谁能与之相比呢？
属于血气类的生物，最愚蠢笨拙的莫过于猪。僧道能让人舍身献产，但不能让猪屈膝接受戒律，难道猪能辟除异端吗？特别敬奉异端的，其实比猪还要愚蠢笨拙。相信巫师不相信医生，以及遇到险急如暴盲等病症，先画符后吃药，延误时间无法救治。怎么能让每个人把这几句话写在家里，用来昭示明确的训诫，永远杜绝这种祸患，功德胜过礼佛念经千万倍。
Jingbao Jingying (Crystal Clear Mirror) is known for its ability to illuminate demons, but now hanging in the air, who can still gently breathe upon it? I wish that from now on it would be carefully preserved, sparing one the effort of cleaning and polishing due to dimness and blurriness.
This condition presents with redness and pain in the eyes, yet discharge (Chi, 眵) and tears are scanty or absent. However, the Qingjing (Black Pupil/Cornea-Iris area) appears shrouded in turbid smoke, with a dull and lifeless luster. In severe cases, it resembles looking through a fogged mirror, unable to reflect the face. Viewed from the side, only a faint glimpse of the Jinjing (Golden Well/Pupil) can be seen. Although the patient may see nearby objects when looking directly, it is no different from viewing through silk gauze. The root cause of this disease lies in the misuse of cold-natured herbs for heat syndromes, which cross-injures the Lipmo (Fat Membrane), compounded by stinginess in medication, prolonged mental fatigue, and lack of rest and recuperation. Clearly, this is an External Obstruction (Wai Zhang, 外障) eye disease, but since the Fenglun (Wind Wheel/Cornea) surface is smooth without any removable opacity, it is termed "Qi Yi" (Gas Opacity). It is extremely difficult to treat. If such symptoms occur after the resolution of an acute opacity due to sudden illness, it indicates that Yuanqi (Original Qi) has not yet recovered, and thus does not fall under this discussion. Medication should be adjusted according to medical records; ten cases can be reliably cured.
The second son of my cousin's brother, Yu Zhaowen, aged sixteen, suffered from wind-heat causing redness and swelling during the late summer. After the physician treated him, his eyes developed Qi Yi, resembling dead eyes that were frightening to look at. His uncle went personally to Nanfang to seek treatment. As a close relative of my grandmother, I accompanied him despite the scorching heat. Upon examination, the symptoms were indeed strange, and the pulse was chaotic. Asking about his preferences and comfort, he stated that his abdomen was full, he had no appetite, felt thirsty and needed to drink, and urinated frequently. Asked about his vision, he said, "Day looks like night." From this, I realized that excessive medication had removed the pathogen but severely damaged the Zangfu (Zang and Fu Organs) Qi. Therefore, I prescribed Fuzi Lizhong Tang (Aconite and Magnolia Root Decoction) added with Danggui (Angelicae Sinensis Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma). In the evening, he took the Zuoyou He Gui Formula. The next day, the lower edge of the Fenglun appeared clear and bright like a new moon, surpassing normal clarity. Continuing with this approach, his vision improved gradually, opening up line by line daily. Exactly fifteen days later, it became completely clear. Later, another person suddenly developed Qi Zhang (Gas Obstruction). By administering Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) during the day and Bawei Dihuang Wan (Eight-Ingredient Rehmannia Pill) at night alternately for over ten days, he also recovered.
Ophthalmology texts do not record this condition, nor do they necessarily use these medicines. Students who can apply this knowledge analogously may hopefully receive my true transmission.
Yinhai Shuanghan (Silver Sea Double Containment/Eyes) shine like pearls illuminating the night. Losing sight so casually causes surprise and doubt. This is not caused by spirits or demons, but rather by hidden Qi movement and temporary separation of Blood. Many patients suffer, few recover. Those who are melancholic and prone to illness need not seek medical help; it is like the waking from the Handan Dream or the cooking of the Yellow Millet—natural processes. Even Chunyang (Pure Yang/Zhang Boduan) would frown at this.
This condition refers to individuals who otherwise have no other diseases, where the external contours are undamaged and the internal Tongs hen (Pupil/Spirit) is intact, yet they suddenly become blind. There are three causes: Yin Gu (Yin Solitude), Yang Gua (Yang Scarcity), and Shen Li (Spirit Separation). Injury to Yang often stems from the Six Desires; injury to Yin often stems from the Seven Emotions; injury to Shen involves both emotions and desires. Some young people whose knowledge is undeveloped, or old people whose worldly affairs are finished, suddenly develop this condition, which does not fall into the above three categories but belongs to Guan Ge (Guan and Ge Syndromes). What is Guan Ge? It refers to disharmony of Yang pulses, where Qi remains in the Fu organs, causing excessive Yang Qi, preventing Yin Qi from nourishing the upper part, hence called "Guan". All exterior contractions involve Qi movement, where pathogens enter via Qi, causing obstruction of the upper orifices, all belonging to Guan. Disharmony of Yin pulses means Blood remains in the Zang organs, causing excessive Yin Qi, preventing Yang Qi from protecting the lower part, hence called "Ge". All miscellaneous diseases arising from Blood issues, where pathogens exit via Blood, causing obstruction of the lower orifices, belong to Ge. When both Yin and Yang are excessive, with no Yang in Yin and no Yin in Yang, and Yin and Yang separate, Yingwei (Nutritive and Defensive Qi) becomes blocked, and Xueqi (Blood and Qi) fail to circulate mutually. This is simultaneous pathogenic invasion of Zang and Fu organs, hence called Guan Ge. In summary, only those with Toufeng (Head Wind), Tanhuo (Phlegm-Fire), deficient Yuanqi, or insufficient fluids will suffer this. With proper maintenance and timely herbal treatment, it will heal spontaneously in a few days; otherwise, it becomes a chronic stubborn disease. This condition occurs rapidly and strangely. People suspect ghosts and gods, consulting shamans first and doctors later. They do not know that urgent treatment can restore sight, but delay leads to fixed pathology where medicine is useless. What can ghosts do? What can monks and Daoists do?
When this condition strikes suddenly, regardless of whether it is Yin, Yang, Shen, or Guan Ge, immediately decoct Dushen Tang (Single Ginseng Decoction), take a few qian, and drink frequently while hot. Then adjust other medications, using only tonification and no purgation, and one might preserve safety. Someone asked the rationale. I replied: Blood is the guardian of Qi, and Qi is the protector of Blood; they accompany each other and do not separate. Thus, Shen rests in its residence, and the eyes are bright. Now, sudden blindness occurs because Qi was first struck by the pathogen. Once Qi is affected, it transmits to Blood, meaning "when Qi is diseased, Blood is also diseased." If there is further loss, Qi becomes solitary Yang, like fierce fire, and Blood becomes solitary Yin, akin to cold water. At this moment, tangible Blood cannot be generated quickly, so the subtle Qi must be urgently protected. Hence, sweet-warm Renshen (Ginseng) is used to consolidate Yuanqi, weighing the urgency. The Classics state: "For blood loss, benefit the Qi; as Yang grows, Yin lengthens." This is what is meant. May I ask the secondary method? It is Guipi Tang (Restore the Spleen Decoction) plus Liu Yi San (Six-to-One Powder). For the poor with no resources, this suffices to meet obligations. But for the precise shot hitting the target, who can match the subtle efficacy of Ginseng?
Among creatures of Blood and Qi, none are more stupid and clumsy than pigs. Monks and Daoists can make humans sacrifice their bodies and wealth, but cannot make pigs kneel and accept precepts. Can pigs repel heterodoxy? Those who revere heterodoxy are even more stupid than pigs. Believing in shamans over doctors, and delaying treatment for critical conditions like sudden blindness by drawing talismans before taking medicine, leads to death. How can everyone write these words at home to clarify instructions and forever prevent this disaster? The merit exceeds millions of times that of bowing to Buddhas and chanting scriptures.
