帝曰∶外障者，肝中得病；内障者，胆中用药。外障肝上有膜，先令吃药
去膜，然后用点药；内障者，胆上有膜，胆汁热枯，用药调理，唤作青风内障，虚
则补之。二十以上，三十以下，凉药多不妨。五十以上，七十以下，宜用温药。赤
眼、毒眼，须用治心肺血气之药。审其虚实，解心肺气，先宜解，后点洗。及
患翳膜，眼睛不疼痛，不用宣解。妇人血气，先治头风，然后治眼，非俗说之谈。
凡人患眼，皆因酒色思虑，忧愁悲哭，食毒咸酸，致令血气不均，肝气损动。调理
肝肺，则用药明矣。

黄帝说：外障眼病，是肝脏受邪所致；内障眼病，需用药物调理胆腑。外障表现为肝区（此处指眼部对应区域）有膜遮蔽，应先服药以去除膜翳，然后再使用眼药点治；内障表现为胆区有膜遮蔽，因胆汁热盛枯竭，需用药物调理，这种病症称为青风内障，治疗原则为虚证则用补法。年龄二十岁以上、三十岁以下者，多用凉性药物无妨；年龄五十岁以上、七十岁以下者，宜用温性药物。赤眼、毒眼，必须使用调理心肺血气的药物。需仔细辨别虚实，先解心肺之气滞，宜先内服解表或理气，后再配合点洗治疗。若患有翳膜但眼睛不疼痛，则不需要使用宣散解表之法。妇女患眼病，若有血气不和，应先治疗头风，然后再治眼疾，这并非世俗的谬论。大凡人患眼病，多因饮酒色欲过度、思虑忧愁悲哭、食用有毒咸酸之物，导致血气失调，肝气受损扰动。调理好肝肺，用药得当，视力自然明亮。
天地造化，阴阳变化通达，五行匹配而显现出物象，四肢形体也依类而成。天上有日月，人有双眼，眼睛与肾脏相通，外部分为五轮，内部对应五脏，运行禀受四时之气，通流全身百脉。这是顺应春和万物生长的时节，木气旺盛之时，此时肝气盛而肾气衰。夏日万物繁荣，火气炎上，此时心气旺而肝气衰。秋令万物收成，金气腾旺，此时肺气旺而肝气衰。冬至阳气潜藏，水性完备，此时肾气旺而肝气生，这被称为子母生成的造化规律。人的眼睛，是肝脏的外在表现。肝气不和，则瘀血灌注瞳孔；肺气不和，则眼睛干涩发痒；脾气不和，则白睛颜色淡黄；肾气不和，则多流出冷泪；心气不和，则时常红赤干涩。血轮受病，可从心脏察知；风轮受病，可从肝脏察知；水轮受病，可从肾脏察知；肉轮受病，可从脾脏察知；气轮受病，可从肺脏察知，这就是相生相克的道理，源流清晰。认识五脏的盛衰，知晓四时的造化，人自出生以来，都依赖气血滋养，若气滞血虚，眼病自然产生。如果气血调和，怎会有这种祸患？人们在社会事务中奔波，大多贪恋酒色，大量冒犯风寒暑湿，饮食口味过重，调养失度，以致肝胆遭受风邪侵袭，进而传入膀胱导致冷泪。冬天严寒，春天凛冽，夏季清凉，秋季酷热，阴阳毒瓦斯由春季三阳所生。因此阴阳混杂于丹田，毒瓦斯一二日离开丹田，三四日停留于脾胃，五六日深入脏腑，或者传变导致目赤，在肝则目痛，在肺则多痒，在肾则视物不明，在脾则眼睑溃烂倒睫，在肝胆则胬肉攀睛，克制脾胃三焦则视物不明，克制膀胱则有头痛流泪、视物昏花等症状，补肝散能奏效。脾冷则眼球干涩发痒，可用驱风散辅助治疗。肾冷则眼前黑花散乱，补肾丸大有奇功。肺冷则视物困难睁眼无力，用清肺散调理。有热症者，用柴胡散发散，仍使通肝散配合。肿胀者，用清肝散通利，兼用凉脾之法。决明散、羚羊角散、还睛散可用于多种疾病施治，地黄丸、定心丸对内部病变有效。胎前产后，檀香散、当归散、二宜散须详细斟酌使用；对于冷热风虚之证，五退散、清凉散、白薇散可酌情选用以验证疗效。眼睛深红，疼痛干涩，乃是肝经实热，应当泻肝、清心、凉脾，效果必然显著。眼睛淡红，微感干涩，乃是肝经虚热，应当温凉调顺驱逐邪气，此病痊愈如常。呼吸粗重、口味不佳，是脾胃积热，翳障遮挡瞳孔，或如粟粒，或成梅花状。白睛肿痛，是肺与大肠积热。不肿而有疮翳者，是肺脏传变的风涎所致。赤脉多者，是心脏虚损。白睛发黄，是酒欲饮食传变至脾胃。血液灌注瞳仁，是心经壅塞热盛。肾经风热，羞明生花，若无翳膜，宜用补法。疼痛如针刺者，通利后即可消除。眼睛痒者，驱风即可痊愈。撞击刺痛者，以止痛为先。斑疮者，宜尽早消毒。调理阴阳，所谓医生乃人的司命之神，通达玄妙细微之理，始终有准则。妄行针刺，药物误用伤人，深可警戒啊。
The Yellow Emperor said: External obstructions (Wai Zhang) are diseases of the Liver; internal obstructions (Nei Zhang) require medication for the Gallbladder. In external obstructions, a membrane forms over the eye region corresponding to the Liver; one must first take oral medicine to remove the membrane, and then apply eye drops. In internal obstructions, a membrane forms over the Gallbladder region, where bile is hot and depleted; medication is used to regulate this condition, known as Qing Feng Nei Zhang (Green Wind Internal Obstruction). The treatment principle is tonification for deficiency. For those aged twenty to thirty, cooling herbs are generally safe. For those aged fifty to seventy, warming herbs are appropriate. For red eyes (Chi Yan) and toxic eyes (Du Yan), medicines that regulate the Qi and Blood of the Heart and Lungs must be used. One must carefully assess excess and deficiency, resolve the Qi stagnation in the Heart and Lungs, preferably starting with internal regulation before using topical washing or dropping therapies. If cataracts or membranes are present but the eyes are not painful, dispersing and resolving methods are not required. For women with eye diseases caused by Qi and Blood disharmony, treat head wind (Tou Feng) first, then treat the eyes; this is not mere vulgar talk. Generally, eye diseases in humans arise from excessive indulgence in alcohol and sex, excessive thinking, worry, sorrow, and crying, as well as consuming toxic, salty, or sour foods, leading to uneven Qi and Blood and damage to Liver Qi. By regulating the Liver and Lungs, proper medication will clearly restore vision.
Heaven and Earth create all things through the transformation of Yin and Yang, and the matching of the Five Elements manifests phenomena, while the four limbs and body take shape according to their categories. Heaven has the sun and moon; humans have two eyes. The eyes connect with the Kidney, externally divided into the Five Wheels (Wu Lun), internally corresponding to the Five Zang Organs, operating in accordance with the Four Seasons, and flowing through the hundred vessels. This follows the harmony of spring when all things grow, a time when Wood Qi is prosperous; thus, Liver Qi is abundant while Kidney Qi declines. In summer, when flora flourishes, Fire Qi flares upward; thus, Heart Qi is abundant while Liver Qi declines. In autumn, when harvest occurs, Metal Qi rises and prospers; thus, Lung Qi is abundant while Liver Qi declines. At winter solstice, roots lie dormant, Water nature is complete; thus, Kidney Qi is abundant and Liver Qi generates, which is called the creation of mother and son generation. Human eyes are the external manifestation of the Liver. If Liver Qi is discordant, blood stasis floods the pupil; if Lung Qi is discordant, the eyes feel dry and itchy; if Spleen Qi is discordant, the sclera turns pale yellow; if Kidney Qi is discordant, cold tears flow excessively; if Heart Qi is discordant, the eyes are frequently red and dry. When the Blood Wheel is diseased, observe the Heart; when the Wind Wheel is diseased, observe the Liver; when the Water Wheel is diseased, observe the Kidney; when the Flesh Wheel is diseased, observe the Spleen; when the Qi Wheel is diseased, observe the Lung. Thus, the principles of mutual generation and restriction are clear and logical. Understanding the prosperity and decline of the Five Zang Organs and knowing the creation of the Four Seasons, since birth, humans rely on Qi and Blood. If Qi stagnates and Blood is deficient, eye diseases naturally arise. If Qi and Blood are harmonious, how could such afflictions exist? People engaging in worldly affairs often indulge in alcohol and sex, expose themselves heavily to wind, cold, heat, and dampness, eat overly flavorful foods, and fail to regulate their lifestyle properly. This leads to the Liver and Gallbladder being invaded by wind pathogenic factors, which then enter the Bladder causing cold tears. Winter is severely cold, spring is biting, summer is cool, and autumn is intensely hot. Yin-Yang toxic vapors are generated by the three Yang energies of spring. Therefore, Yin and Yang mix in the Dantian; after one or two days, the toxic vapor leaves the Dantian; after three or four days, it stays in the Spleen and Stomach; after five or six days, it enters the Zang-Fu organs. It may transmit and cause red eyes; if in the Liver, there is eye pain; if in the Lung, there is frequent itching; if in the Kidney, vision is unclear; if in the Spleen, there is eyelid ulceration and trichiasis; if in the Liver and Gallbladder, there is pterygium (Rou Pan Jing); if restricting the Spleen, Stomach, and San Jiao, vision is unclear; if restricting the Bladder, there is headache and tearing, and blurred vision. Bu Gan San (Liver Tonifying Powder) can be effective. If the Spleen is cold, the eyeballs are dry and itchy; Qu Feng San (Wind-Expelling Powder) assists in treatment. If the Kidney is cold, black spots scatter in vision; Bu Shen Wan (Kidney Tonifying Pill) has great efficacy. If the Lung is cold, opening the eyes to see is difficult; Qing Fei San (Lung-Clearing Powder) regulates it. If there is heat, Chai Hu San (Bupleurum Powder) disperses it, still using Tong Gan San (Liver-Unblocking Powder). If there is swelling, Qing Gan San (Liver-Clearing Powder) unblocks and promotes urination, combined with cooling the Spleen. Jie Ming San (Cassia Seed Powder), Ling Yang Jiao San (Antelope Horn Powder), and Huan Jing San (Vision-Restoring Powder) are applied for various diseases; Di Huang Wan (Rehmannia Pill) and Ding Xin Wan (Heart-Calming Pill) are effective for internal conditions. Before and after childbirth, Tan Xiang San (Sandalwood Powder), Dang Gui San (Angelica Sinensis Powder), and Er Yi San (Two Appropriate Powders) must be used with detailed consideration. For cold, heat, wind, and deficiency patterns, Wu Tui San (Five Retreats Powder), Qing Liang San (Cooling Powder), and Bai Wei San (Clerodendrum Powder) should be chosen flexibly to verify efficacy. Deep red eyes with pain and dryness indicate excess heat in the Liver Meridian; one must purge the Liver, clear the Heart, and cool the Spleen, and the effect will surely be achieved. Pale red eyes with slight dryness indicate deficiency heat in the Liver Meridian; one must use warming and cooling methods to harmonize and expel, and the disease will heal as before. Rough breathing and loss of taste indicate accumulated heat in the Spleen and Stomach. Opacities blocking the pupil may resemble millet grains or plum blossoms. Swollen and painful sclera indicates accumulated heat in the Lung and Large Intestine. Non-swollen sores or opacities indicate wind-phlegm transmitted from the Lung. Numerous red vessels indicate Heart deficiency. Yellow sclera indicates transmission of wine desire and diet to the Spleen and Stomach. Blood flooding the pupil indicates congestion and heat in the Heart Meridian. Wind-heat in the Kidney Meridian causes photophobia and visual halos; if there are no opacities, tonification is suitable. Pain like needle pricking is relieved by unblocking. Itching is cured by expelling wind. Trauma pain requires pain relief first. Spots and sores require early disinfection. Regulating Yin and Yang, the physician is indeed the master of life for humans, penetrating profound subtleties, with consistent standards throughout. Reckless acupuncture and erroneous medication harm the body; this must be deeply guarded against.
