治眼疾暴发红肿疼痛。或 多 肉，或渐生云翳，及因有火而眼即发干昏花者。
蓬砂（五钱） 芒硝（三钱，硝中若不明亮用水化开澄去其中泥土）
上药和凉水多半盅，研至融化。用点眼上，一日约点三十次。若陈目病一日点十余次。冬日须将药碗置热
水中，候温点之。
治眼疾由热者。
黄连（二钱） 为细末，香油调如薄糊，常常以鼻闻之，日约二三十次。勿论左右眼患证，应须两鼻孔皆闻。
目系神经连于脑，脑部因热生炎，病及神经，必生眼疾。彼服药无捷效者，因所用之药不能直达脑部故也。
愚悟得此理，借鼻窍为快捷方式，以直达于脑。凡眼目红肿之疾，及一切目疾之因热者，莫不随手奏效。
治目瞳散大昏耗，或觉视物乏力。
萸肉（二两，去净核） 野台参（六钱） 柏子仁（一两，炒） 玄参（一两） 菟丝子（一两，炒）
羊肝（一具，切片焙干）
上药共为细末，炼蜜为丸桐子大。每服三钱，开水送下，日两次。
一妇人，年三旬。瞳子散大，视物不真，不能针黹。屡次服药无效，其脉大而无力。为制此丸，服两月全愈。
治同前证，因有热而益甚者。
羊肝一具，切片晒干（冬日可用，慢火焙干）。
上一味轧细，用猪胆汁和为丸，桐子大，朱砂为衣。每服二钱，开水送下，日再服。
按∶此方若用熊胆为丸更佳。内地鲜熊胆不易得，至干者又难辨其真伪，不如径用猪胆汁为稳妥也。
【附方】护眉神应散 治一切眼疾。无论气蒙、火蒙、肉螺、云翳、或瞳人反背。未过十年者，皆
见效。方用炉甘石一两 透，童便淬七次。珍珠二颗，大如绿豆以上者，纳通草中 之，珠爆即速取出。血琥
珀三分，真梅片二分，半两钱、五铢钱（俗名马镫钱）、开元钱各一个，皆 红醋淬七次，共为细末，乳调涂
眉上，日二三次。
一室女。病目年余，医治无效，渐生云翳。愚为出方，服之见轻，停药仍然反复。后得此方，如法制好，
涂数次即见轻，未尽剂而愈，妙哉。按此方若加薄荷冰二分更效。
瞳人反背之证，最为难治，以其系目系神经病也。盖目系神经，若一边纵，一边缩，目之光线必斜，视物
即不真。若纵、缩之距离甚大，其瞳人即可反背。治此证者，当以养其目系神经为主。此方多用金石珍贵之品，
其中含有宝气。凡物之含有宝气者，皆善能养人筋肉，使筋肉不腐烂。目系神经，即脑气筋之连于目者。以此
药涂眉上，中有冰片之善通窍透膜者，能引药气直
达脑部，以养目系神经，目系神经之病者自愈。而瞳人反背及一切眼疾，亦自愈矣。
【附方】治暴发眼便方。其眼疾初得肿疼者，用生姜三四钱、食盐一大撮，同捣烂，薄布包住，蘸新汲
井泉水，擦上下眼皮。屡蘸屡擦，以擦至眼皮极热为度。擦完用温水将眼皮洗净。轻者一次即愈，重者一日擦
两次亦可愈。然擦时须紧闭其目，勿令药汁入眼中。
【附案】晋书盛彦母氏失明，躬自侍养，母食必自哺之。母病既久，至于婢使，数见捶鞭。婢愤恨，伺
彦暂行，取蛴螬炙饴之，母食以为美，然疑是异物，密藏以示彦。彦见之，抱母恸哭，绝而复苏。母目豁然，
从此遂愈。
按蛴螬生粪土中，形状如蚕（俗名地蚕）遍处皆有。《神农本草经》谓，主目中淫肤、青翳、白膜。其善
治目翳可知。内障宜油炙服之，外障宜取其汁，滴目中。
治疗眼疾突然发作，出现红肿疼痛。或者长出胬肉（翼状胬肉），或者逐渐生成云翳（角膜混浊），以及因为体内有火而导致眼睛发干、视物昏花的情况。
蓬砂（五钱） 芒硝（三钱，如果硝石不够明亮，用水化开后澄清，去除其中的泥土杂质）
将上述药物与大半盅凉水混合，研磨至完全融化。用药液点入眼中，每天大约点三十次。如果是陈旧的眼病，每天点十几次即可。冬天必须将药碗放在热水中，待温度适宜后再点用。
黄连（二钱） 研成细末，用香油调成稀薄的糊状，经常用鼻子闻嗅，每天约二三十次。无论哪只眼睛患病，两个鼻孔都应该闻嗅。
目系神经连接于脑部，脑部因热产生炎症，病变波及神经，必然导致眼疾。那些服药没有迅速见效的人，是因为所用的药物不能直接到达脑部。我领悟到这个道理，借助鼻窍作为快捷途径，使药效直达脑部。凡是眼睛红肿的疾病，以及一切因热引起的眼疾，没有不随手奏效的。
治疗瞳孔散大、视力耗损，或者感觉看东西费力。
山茱萸（二两，去净果核） 野台参（六钱） 柏子仁（一两，炒制） 玄参（一两） 菟丝子（一两，炒制）
羊肝（一个，切片焙干）
将上述药物共同研成细末，用炼蜜制成如梧桐子大小的丸剂。每次服用三钱，开水送服，每天两次。
有一位妇女，三十岁。瞳孔散大，视物不清，无法进行刺绣等精细工作。多次服药无效，她的脉象大而无力。我为她配制了这种丸药，服用两个月后完全痊愈。
治疗与前证相同，但因有热邪而症状加重者。
将这一味药轧成细粉，用猪胆汁调和制成丸剂，大小如梧桐子，以朱砂为衣。每次服用二钱，开水送服，每天两次。
按语：此方如果使用熊胆制作丸剂效果更佳。内地难以获得新鲜的熊胆，至于干燥的熊胆又难以辨别真伪，不如直接使用猪胆汁更为稳妥。
【附方】护眉神应散 治疗各种眼疾。无论是气蒙、火蒙、胬肉攀睛、云翳，或者是瞳人反背（瞳孔移位/斜视）。病程未超过十年的，都能见效。方用炉甘石一两，用童便淬炼七次。珍珠两颗，直径大于绿豆的，放入通草中，珍珠爆裂时立即取出。血琥珀三分，真梅片（冰片）二分，半两钱、五铢钱（俗称马镫钱）、开元钱各一枚，都用红醋淬炼七次，共同研成细末，用乳汁调匀涂抹在眉毛上，每天二三次。
有一位未婚女子。患眼病一年多，医治无效，逐渐生出云翳。我为她开出方子，服药后病情减轻，停药后仍然反复。后来得到这个方子，按照方法制作好，涂抹几次后病情减轻，还没用完药就痊愈了，真是奇妙啊。按语：此方如果加入薄荷脑二分效果更好。
瞳人反背的症状，最为难治，因为它属于目系神经的疾病。大概目系神经，如果一边松弛一边收缩，眼睛的光线必然偏斜，视物就不清晰。如果松弛和收缩的距离很大，瞳孔就会发生反背。治疗这个病症，应当以滋养目系神经为主。此方多使用金石珍贵药材，其中含有“宝气”。凡是有宝气的物体，都善于滋养人的筋肉，使筋肉不腐烂。目系神经，就是脑气筋连接于眼睛的部分。将此药涂抹在眉毛上，其中有冰片善于通窍透膜的特性，能引导药气直达脑部，以滋养目系神经，目系神经的疾病自然痊愈。而瞳人反背及一切眼疾，也会随之自愈。
【附方】治疗暴发眼疾简便方。对于刚得病出现肿胀疼痛的眼睛，用生姜三四钱、食盐一大撮，一起捣烂，用薄布包住，蘸取新打的井泉水，擦拭上下眼皮。多次蘸取多次擦拭，直到擦拭到眼皮极热为止。擦完后用温水将眼皮洗净。轻症一次即愈，重症一天擦两次也可以痊愈。然而擦拭时必须紧闭双眼，不要让药汁进入眼中。
【附案】《晋书》记载盛彦的母亲失明，他亲自侍奉供养，母亲吃饭必定亲自喂食。母亲生病久了，以至于婢女使唤她，多次遭到鞭打。婢女愤恨，趁盛彦暂时离开，取来蛴螬（金龟子幼虫）烤熟拌饴糖喂给老人吃，母亲觉得味道很美，但怀疑是异物，秘密藏起来给盛彦看。盛彦看到后，抱着母亲痛哭，母亲昏厥后又苏醒过来。母亲的眼睛豁然开朗，从此痊愈。
按语：蛴螬生长在粪土中，形状像蚕（俗称地蚕），到处都有。《神农本草经》说，它能主治目中淫肤、青翳、白膜。它善于治疗目翳是显而易见的。内障宜油炙后服用，外障宜取其汁液滴入眼中。
Treats sudden onset of eye diseases characterized by redness, swelling, and pain. Or the growth of pterygium (wing-shaped fleshy tissue), or the gradual formation of corneal opacity (cloudy film). Also treats cases where internal heat causes dryness and blurred vision.
Pengsha (5 qian) Mangxiao (3 qian; if the saltpeter is not bright, dissolve it in water, let it settle, and remove mud impurities)
Mix the above herbs with half a cup of cold water, grind until completely dissolved. Apply as eye drops, approximately thirty times a day. For chronic eye conditions, apply ten to twenty times a day. In winter, place the medicine bowl in hot water and wait until it is warm before application.
Treats eye diseases caused by heat pathogens.
Huanglian (2 qian) Grind into fine powder, mix with sesame oil to form a thin paste. Inhale frequently through the nose, about twenty to thirty times a day. Regardless of which eye is affected, both nostrils should be used for inhalation.
The optic nerve connects to the brain. If the brain suffers from inflammation due to heat, the pathology affects the nerves, inevitably leading to eye disease. Those who take oral medication without rapid effect do so because the drugs cannot reach the brain directly. I have realized this principle and utilize the nasal cavity as a shortcut to deliver the medicinal effect directly to the brain. For any eye redness and swelling, and all eye diseases caused by heat, there is no case that does not respond promptly.
Treats dilated pupils and visual fatigue, or the sensation of difficulty in seeing.
Yurou (Cornus officinalis fruit, 2 liang, pits removed completely) Yetaishen (Wild Panax ginseng, 6 qian) Baiziren (Biota seed, 1 liang, stir-fried) Xuanshen (Scrophularia root, 1 liang) Tusizi (Cuscuta seed, 1 liang, stir-fried)
Yanggan (Sheep liver, one piece, sliced and dried)
Grind all herbs into fine powder, bind with refined honey to make pills the size of tung tree seeds. Take 3 qian per dose, washed down with boiled water, twice daily.
A woman, aged thirty, had dilated pupils and unclear vision, unable to perform needlework. Previous medications were ineffective; her pulse was large but weak. I prepared these pills for her, and after two months of consumption, she was fully cured.
Treats the same condition as above, but exacerbated by heat.
Yanggan (Sheep liver, one piece, sliced and sun-dried; in winter, slow-fire dried).
Grind this single ingredient into fine powder, mix with pig bile to form pills the size of tung tree seeds, coated with Zhusha (Cinnabar). Take 2 qian per dose, washed down with boiled water, twice daily.
Note: This formula would be more effective if made with Xiongdan (Bear bile). Fresh bear bile is hard to obtain inland, and dried bear bile is difficult to authenticate, so using pig bile is safer.
[Supplementary Formula] Humei Shenyingsan (Eyebrow-Protecting Divine Efficacy Powder) Treats all types of eye diseases. Whether caused by qi obstruction, fire obstruction, pterygium, corneal opacity, or pupillary displacement (strabismus/dyscoria). For conditions lasting less than ten years, efficacy is observed. Use Luganshi (Calamina) 1 liang, quenched seven times in tongbian (child's urine). Zhenzhu (Pearl) 2 pieces (larger than mung beans), placed inside Tongcao (Rice Paper Pith); when the pearl cracks, remove immediately. Xuehupo (Blood Amber) 3 fen, Zhen Meipian (Borneol) 2 fen. One each of Banliangqian, Wuzhuqian (commonly known as Madengqian/Mounting Iron Coin), and Kaiyuanqian, all quenched seven times in red vinegar. Grind all into fine powder, mix with milk, and apply to the eyebrows two to three times daily.
An unmarried maiden suffered from an eye disease for over a year with no medical success, gradually developing corneal opacity. I prescribed a formula; symptoms improved while taking it, but relapsed upon stopping. Later, she obtained this formula, prepared it correctly, and applied it several times. Symptoms lightened, and she was cured before finishing the dosage. Truly miraculous. Note: Adding Bohebing (Menthol) 2 fen would enhance efficacy.
Pupillary displacement (dyscoria) is the most difficult to treat, as it involves pathology of the optic nerve. Essentially, if the optic nerve has uneven tension (one side relaxed, one side contracted), the eye's optical axis deviates, causing unclear vision. If the disparity in tension is significant, pupillary displacement occurs. Treatment should focus on nourishing the optic nerve. This formula uses precious mineral and metal substances containing "baoqi" (precious energy/vitality). Substances with baoqi are excellent at nourishing human muscles and tendons, preventing decay. The optic nerve is the extension of the brain's qi-tendons connecting to the eye. Applying this medicine to the eyebrows utilizes Borneol's ability to open orifices and penetrate membranes, guiding the medicinal qi directly to the brain to nourish the optic nerve. Thus, optic nerve pathology heals spontaneously, along with pupillary displacement and all other eye diseases.
[Supplementary Formula] Simple Prescription for Sudden Onset Eye Disease. For eyes initially swollen and painful, use 3-4 qian of Shengjiang (Fresh Ginger) and a large pinch of Yanshi (Salt). Pound together until pasty, wrap in thin cloth, dip in fresh well water, and wipe the upper and lower eyelids. Repeat dipping and wiping until the eyelids feel extremely hot. After wiping, wash the eyelids clean with warm water. Mild cases heal in one session; severe cases may require twice daily application. However, keep eyes tightly closed during application to prevent medicinal juice from entering the eyes.
[Supplementary Case] The Book of Jin records that Sheng Yan's mother went blind. He personally cared for her, feeding her by hand. Due to prolonged illness, she became subject to the whims of servants and was often whipped out of frustration. A maid, resentful, took silkworm grubs (Qilao/Larva of Scarabaeidae), roasted them with maltose, and fed them to the old lady. The mother found them delicious but suspected they were strange objects, hiding them secretly to show Sheng Yan. Upon seeing this, Sheng Yan embraced his mother and wept bitterly. His mother fainted and then revived. Her eyes suddenly cleared, and she was cured thereafter.
Note: Qilao lives in manure and soil, resembling silkworms (commonly called Digcan/Ground Silkworm), and is ubiquitous. The *Shennong Ben Cao Jing* states it treats ocular hyperplasia, blue opacities, and white membranes. Its efficacy in treating corneal opacity is evident. For internal cataracts, it should be fried in oil and ingested; for external opacities, its juice should be extracted and dropped into the eyes.
