伤寒病痊愈后，有的人眼睛再次发生严重疾病。这是因为清阳之气不能上升，残余的病邪向上侵入头面空窍所致。其病症表现为眼睑涩痛、红肿充血、生翳膜、畏光，以及头脑和骨骼疼痛。治疗应当辅助清阳之气上升外出，病即可痊愈。最忌讳使用大黄、芒硝等苦寒通利之药，若误用则病情难以再治。
女性出现逆经（经血逆行），血液灌注入瞳神，满眼红赤涩痛，这是血热导致经闭，过期不行，于是血液逆行于上。如果形成血翳，切不可用刀钩割。只需用四物汤加入行气、破血、通经的药物。月经通畅后，血翳自然消退。若病情严重，必须加入酒制大黄以泻下攻逐，遏制病势。去除火热之邪是为了保存阴液，这正是针对肝虚血少的情况，不得不将退火作为紧急任务。火热之邪若不向下攻逐，就会灼伤真阴，导致阳气更加亢盛而阴液更加枯竭。人们只知道用四物汤补血，哪里知道大黄也能起到补血的作用呢？如果因为患者体虚而单纯使用补药，不仅无益，简直是抱薪救火。
妊娠期间患眼病，必须区分是气分病变还是血分病变。气分病变则有眼睑浮肿、瞳神散大等症状；血分病变则有瘀血凝滞成脂等病症。这是因为孕妇的阴阳气血运行涩滞，与常人不同。内服攻伐药物恐怕会损伤胎气导致流产，不攻伐则病邪不能去除。然而只要善于运用内护外劫的方法，就能百发百中。
分娩时全身血脉都随之动荡，邪气容易乘虚而入。此时肝部升发之气非常微弱，胆腑失去滋养，胆汁不充盈，那么眼中的膏液也就失去了化生的源头。所以产后眼病大多是由内部正气不足引起的。大致来说，产后患病应当尽早治疗，不要拖延。拖延久了，气血安定下来，病邪就会深入，治疗也就不容易了。那些外在症状明显且危害大的，人们都知道害怕而及早治疗；那些内在症状危害较缓的，人们往往忽视它们。等到病已成定局，后悔也来不及了。
痘疮侵入眼睛，在痘疮初生时，如果眼睛紧闭不开，眼皮上有痘疮，或者痘疮长在黑睛（角膜）上，应立即取益母草煎汤熏洗，每天三次。再用鳝鱼血点眼。注意忌口及防止婴儿夜啼，乳母也要忌口。必须等痘疮痊愈，眼睛逐渐睁开，眼中的痘疮也会随之痊愈。初期痘疮入眼，可选用决明散、密蒙散；痘疮入眼形成翳膜的，选用谷精散、神功散。民间验方：用望月砂粉末，配生鸡肝研烂，在饭上蒸熟，每日空腹食用，效果显著。大致而言，治疗越早，越容易消退且不变证；治疗晚则消退慢。现在的人只要见到痘后眼疾，就说无法治疗，不知道只要瞳神没有受损，即使时间久远，也有可治的道理。只有当病程长久，血液凝固，精气凝结，障翳深沉滑利且造成视力损害时，才属于不治之症。倪仲贤说：斑疹余毒所致的眼病，与风热失控的病证，稍有相似但又有不同。总起来看类似羚羊散主治的情况。如果大便不硬，减少硝石和大黄的用量；未满二十一日发病的，应以消毒化斑为主。斑疹后出现的风热翳膜，气晕遮蔽视线，用泻青丸泻火，效果显著。痘疹疮痂落尽，肌体肥壮，眼中忽然变红，这是余毒郁结而发出的表现。此证最为剧烈，失治多能损害视力。只用车前草研磨取水，频频灌服，以涤除肝经的热毒，再用益母草清洗，用鳝鱼血点眼。
胎风赤烂证 此证有三种情况。一是产时血露进入眼中，清洗不干净而导致红烂，用莱菔（萝卜）捣汁点眼。二是胎儿在母腹中时，母亲多吃壅滞毒性的辛热食物，出生后一百天出现红烂，用犀角地黄汤加黄连，母子共同服用。三是乳母身体壮实，乳头胀满，乳汁喷射到婴儿眼中导致红烂，用黄连汤擦拭干净，单味煅炉甘石粉吹点。
小儿疳眼证 都是由过食损伤脾胃，导致腹胀，午后发热，直到夜间才退去。日久头发稀疏并腹泻，腹泻严重时口渴。食积发热时间久了，就会损伤肝胆，白仁发红，渐渐生出翳膜，遮盖满黑珠，突起如黑豆或香菇状。可用决明鸡肝散，或用羊肝蘸夜明砂给患儿吃，或用绿矾一两，包裹在馒头中去馅煨烤，外面烧黑，里面通红，取出后用密陀僧、夜明砂等分为末，煮枣肉捣成黍米大小的丸剂，每次服用二三十丸，根据孩子大小，空腹米汤送下。务必忌口。翳膜用人乳频频点眼，自然会脱落。如果发展到声音嘶哑、口干、手脚都肿胀，十个人中难救一个。
After the recovery from Shanghan (Cold Damage disease), some individuals may suffer from severe eye diseases again. This is due to the failure of Clear Yang Qi (vital energy ascending) to rise, with residual pathogenic factors moving upward into the orifices. The symptoms include eyelid astringency and swelling, redness and distension, formation of corneal opacities (nebulae), photophobia, as well as headache and bone pain. Treatment should assist the ascent and outward movement of Clear Yang Qi, after which the condition will resolve. It is strictly contraindicated to use Da Huang (Rhei Radix et Rhizoma) and Mang Xiao (Natrii Sulfas), bitter-cold purgatives; if misused, the condition becomes incurable.
Women experiencing Ni Jing (retrograde menstruation) where blood floods the pupil, presenting with full-eye redness and astringency, suffer from Blood Heat causing amenorrhea. When the menses are overdue and do not flow, blood reverses its course upward. If a blood nebula forms, it must absolutely not be cut with hooks. One should only use Si Wu Tang (Four Substances Decoction) combined with herbs that promote Qi circulation, break blood stasis, and unblock menstruation. Once menstruation flows, the blood nebula will naturally recede. In severe cases, Jiu Da Huang (Wine-processed Rhei Radix et Rhizoma) must be added to purge downward and curb the pathogenic momentum. Eliminating Fire preserves Yin, which is urgent for addressing Liver deficiency and Blood insufficiency. If Fire is not purged downward, it will scorch True Yin, leading to hyperactive Yang and exhausted Yin. People know only to use Si Wu Tang to tonify Blood, but who knows that Da Huang can also benefit Blood? Using tonic medicines solely because of deficiency is not only useless but akin to carrying firewood to save a burning house.
Eye diseases during pregnancy must be differentiated into Qi-level and Blood-level patterns. Qi-level patterns present with eyelid edema and dilated pupils; Blood-level patterns present with blood stasis coagulating into lipid-like deposits. This is because the Yin and Yang and Qi and Blood circulation in pregnant women is sluggish and different from normal individuals. Internal attacking treatments risk damaging the fetus and depleting Qi, while failing to attack leaves the disease unresolved. However, by skillfully employing methods of internal protection and external binding, success can be achieved consistently.
Childbirth causes all meridians and vessels to move, making it easy for pathogens to invade. The ascending Qi of the Liver is very weak, and the Gallbladder loses nourishment, resulting in insufficient bile juice. Consequently, the fluids of the eye lose their source of transformation. Therefore, postpartum eye diseases are mostly caused by internal deficiency. Generally, postpartum illnesses should be treated early; do not wait until they become chronic. Prolonged illness leads to settled Qi and Blood, deepening the pathology and making treatment difficult. External symptoms that are obviously harmful are recognized and treated early; internal symptoms with slower progression are often ignored. By the time the disease is established, regret comes too late.
When smallpox enters the eyes: at the initial stage, if the eyes are closed and cannot open, or if smallpox lesions appear on the eyelids or on the cornea (Hei Ming), immediately take Yi Mu Cao (Leonuri Herba), decoct it, and fumigate/wash the eyes three times daily. Also apply leech blood (Shan Xue, here referring to eel blood in context) to the eyes. Observe dietary restrictions and prevent infant night crying; the nursing mother must also observe dietary restrictions. Only after the smallpox has healed and the eyes gradually open will the lesions in the eyes heal. For initial smallpox entering the eyes, Jue Ming San (Cassia Seed Powder) or Mi Meng San (Descurainiae Semen Powder) can be used. For smallpox entering the eyes forming opacities, Gu Jing San (Euphrasia Powder) or Shen Gong San (Divine Efficacy Powder) can be selected. Folk prescription: Use Wang Yue Sha (Leporis Faeces) powder, mixed with raw chicken liver pounded into a paste, steamed over rice. Consume on an empty stomach daily for efficacy. Generally, earlier treatment leads to easier resolution without complications; delayed treatment results in slow resolution. Nowadays, people see post-smallpox eye disease and declare it incurable, not knowing that as long as the pupil is not damaged, there is hope for cure even after a long time. Only when the disease lingers, blood settles, essence condenses, and the opacity becomes deep, smooth, and damaging to vision, is it considered incurable. Ni Zhongxian stated that eye damage caused by residual toxins from macules and rashes is slightly similar to but distinct from diseases caused by unconstrained Wind-Heat. Generally, Ling Yang San (Antelope Horn Powder) is the main formula. If the stool is not hard, reduce the dosage of Xiao Shi (Natrii Sulfas) and Da Huang. If the disease occurs within twenty-one days, focus primarily on detoxification and resolving macules. For Wind-Heat opacities and misty obstructions covering the vision after macules/rashes, Xie Qing Wan (Drain Green Pill) for draining heat is highly effective. After the crusts of smallpox/rashes have fallen off and the body is robust, sudden redness in the eyes indicates residual toxins stagnating and erupting. This pattern is most severe; untreated, it often damages vision. Use Che Qian Cao (Plantaginis Herba) ground and extracted with water, administered frequently to drink, to wash out Heat-Toxin from the Liver Meridian. Wash with Yi Mu Cao, and apply eel blood.
Tai Feng Chi Lan Syndrome (Neonatal Ophthalmia with Redness and Ulceration) has three types. First, birth fluids enter the eye, and incomplete washing leads to redness and ulceration; treat with fresh radish (Lai Fu Zi) juice applied to the eye. Second, during gestation, the mother consumed excessive cloying, toxic, acrid, and hot foods, leading to redness and ulceration one hundred days after birth; treat with Xi Jiao Di Huang Tang (Rhino Horn and Rehmannia Decoction) plus Huang Lian (Coptidis Rhizoma), taken by both mother and child. Third, the nursing mother is robust with engorged nipples, and milk sprays into the infant's eyes causing redness and ulceration; wipe clean with Huang Lian Tang, then apply calcined Lu Gan Shi (Halloysitum Rubrum) powder alone.
Xiao Er Gan Yan Syndrome (Infantile Malnutrition Eye Disease) is caused by overeating damaging the Spleen and Stomach, leading to abdominal distension, afternoon fever that subsides at night, sparse hair, and diarrhea over time. Severe diarrhea leads to thirst. Prolonged food-stagnation fever damages the Liver and Gallbladder. The sclera turns red, and opacities gradually form, covering the cornea, protruding like black beans or shiitake mushrooms. Treat with Jue Ming Ji Gan San (Cassia Seed and Chicken Liver Powder), or feed sheep liver dipped in Ye Ming Sha (Tardigrada). Alternatively, use Lv Fan (Chalcanthite) one tael, wrapped in mantou dough (without filling) and baked until the outside is black and inside red. Take out, mix with Mi Tuo Seng (Lithargyrum) and Ye Ming Sha in equal parts, pound into powder, and make pills with jujube meat paste, sized like millet grains. Administer 20-30 pills per dose according to the child's size, with rice soup on an empty stomach. Strictly observe dietary restrictions. Frequent application of human breast milk to the opacity will cause it to fall off spontaneously. If the condition progresses to hoarseness, dry mouth, and swelling of hands and feet, fewer than one in ten can be saved.
