目为五脏之精华，五脏精气皆上注于目，故阴阳
合德而为精明也。丹溪曰∶目病属风热血少。夫痘蕴
非常之热，自里而达于外。苟气血弱，不能逐毒外
出，则毒火内蕴而血脉逆行，斯痘毒攻于目矣。
按小儿眼症，偶感风热，无伤于通灵虚窍，治疗
尚易。至于痘毒入目，轻则云翳遮蔽瞳人，重则乌珠
突出下陷，极难调理。因将张体仁、傅仁宇、翟玉华
诸前辈治疗痘后眼症诸方，详列于后，令婴儿目病者，
照验过成方，加减服之，庶几转暗为明，复见天日。
大约气血未定，经络未冷时，早治可痊，久恐不能也。
为儿父母者，往往悠忽，多不留心，殊不知一时失
治，即成终身黑暗之苦，岂不深可叹哉！
痘后目赤肿不开，宜用∶
川芎 当归 防风 羌活 薄荷 山栀 甘草
（各等分）
水煎，食后服。
睛疼昏暗，加石膏、南谷精草、绿豆皮。
睛有翳膜，加蝉蜕、白蒺藜。
实热便秘，加大黄。
按川芎、当归入肝经，养肝血。肝主乎风，防风、
羌活、薄荷，皆风药也。肝者火之母，一火动则五火
俱煽而动，栀子、甘草所以清肝火也。诸药皆涤荡之
品，故曰洗肝散。洗矾连膏。
痘后目不赤肿疼，黑暗处则开，见阳光则泪出，
瘾涩难开，宜用∶
眼睛是五脏精华的汇聚之处，五脏的精气都向上灌注于眼睛，因此阴阳和谐交融而形成了视觉的清明。朱丹溪说：眼病属于风热和血少。痘毒蕴藏着非同寻常的热邪，从体内向体表发散。如果气血虚弱，不能将毒邪驱逐出体外，那么毒火就会在体内蕴结，导致血脉运行逆乱，这样痘毒就会攻冲眼睛。
考察小儿的眼部病症，如果是偶然感受风热，没有损伤到通灵的空窍（指眼睛），治疗还比较容易。至于痘毒侵入眼睛，轻则云翳遮蔽瞳孔，重则黑眼球突出或下陷，极难调理。因此将张体仁、傅仁宇、翟玉华等前辈治疗痘后眼病的各种方剂，详细列在后面，让婴儿患眼病的患者，参照验证这些成方，进行加减服用，或许能使昏暗转为光明，重新看见天地日光。
大抵在气血尚未稳定、经络尚未冷滞的时候，早期治疗可以痊愈，拖延久了恐怕就不能治愈了。作为孩子的父母，往往疏忽大意，大多不留心，却不知道一时的失治，就会造成终身黑暗的痛苦，这难道不令人深深叹息吗！
痘后眼睛红肿胀痛无法睁开，适宜使用：
用水煎煮，饭后服用。
眼睛疼痛且视物昏暗，加石膏、南谷精草、绿豆皮。
眼睛有翳膜，加蝉蜕、白蒺藜。
实热便秘，加大黄。
按语：川芎、当归入肝经，滋养肝血。肝主风，防风、羌活、薄荷，都是风药。肝是火的母亲，一旦肝火动，五火都会煽动而发作，栀子、甘草用来清泻肝火。这些药物都是涤荡邪气的品种，所以称为洗肝散。另有洗矾连膏。
痘后眼睛不红肿胀痛，在黑暗处能睁开，见到阳光就流泪，眼睑涩滞难以睁开，适宜使用：
The eyes are the gathering place of the essence of the five Zang organs, and the essential Qi of all five Zang organs ascends to pour into the eyes. Therefore, Yin and Yang harmonize to form clear vision. Zhu Danxi stated: Eye diseases belong to Wind-Heat and Blood deficiency. The smallpox toxin harbors extraordinary heat, spreading from the interior to the exterior. If Qi and Blood are weak and unable to expel the toxin outward, the toxic fire will accumulate internally, causing the blood vessels to flow in reverse, thus allowing the smallpox toxin to attack the eyes.
Regarding eye conditions in children, if they are merely caused by an occasional contraction of Wind-Heat without damaging the sensitive orifices (referring to the eyes), treatment is relatively easy. However, when the smallpox toxin enters the eyes, it may be mild, with nebulae obscuring the pupil, or severe, with the eyeball protruding or sinking, making it extremely difficult to manage. Therefore, various prescriptions for treating post-smallpox eye conditions by predecessors such as Zhang Tiren, Fu Renyu, and Zhai Yuhua are listed in detail below. Infants suffering from eye diseases should refer to these established formulas, modify them as needed, and take them, so that darkness may turn to light, and one may see the sky and sun again.
Generally, when Qi and Blood have not yet stabilized and the meridians have not yet become cold, early treatment can lead to a cure; if delayed for too long, recovery may be impossible. Parents often neglect this matter, failing to pay attention, unaware that a momentary failure in treatment can result in lifelong blindness. Is this not deeply lamentable?
For post-smallpox redness, swelling, pain, and inability to open the eyes, the following is suitable:
Chuanxiong Rhizoma (Chuanxiong), Angelicae Sinensis Radix (Danggui), Saposhnikoviae Radix (Fangfeng), Notopterygii Rhizoma et Radix (Qianghuo), Menthae Haplocalycis Herba (Bohe), Gardeniae Fructus (Shanzhi), Glycyrrhizae Radix et Rhizoma (Gancao) (equal parts).
Decoct in water and take after meals.
If there is eye pain and dim vision, add Gypsum Fibrosum (Shigao), Euphrasiae Herba (Nangujingcao), and Phaseoli Volubilis Pericarpium (Lvdoupi).
If there are nebulae on the eyes, add Bombyx Batryticatus (Chantui) and Tribuli Fructus (Bajili).
If there is excess Heat and constipation, add Rhei Radix et Rhizoma (Dahuang).
Note: Chuanxiong and Danggui enter the Liver Meridian to nourish Liver Blood. The Liver governs Wind; Fangfeng, Qianghuo, and Bohe are all Wind-dispelling herbs. The Liver is the mother of Fire; once Liver Fire moves, the Five Fires will all flare up. Zhizi and Gancao are used to clear Liver Fire. These drugs are all agents for cleansing and washing away pathogens, hence the name Xi Gan San (Washing Liver Decoction). There is also Xifanlian Gao (Washing Alum and Coptis Ointment).
For post-smallpox eyes without redness, swelling, or pain, which can open in dark places but tear upon exposure to sunlight, and feel gritty and difficult to open, the following is suitable:
