5. 外障眼病没有寒证这一句就讲完了，五轮（指瞳仁、黑睛、两眦、白睛、眼睑）变红是因为火邪产生。内障眼病有虚证，是心肾虚弱，所以像没生病的人一样，只是损伤了光明。火能作为外在的借鉴，水能在内部照耀，养护心神、壮补肾水自然能收到功效。五风在内变化产生的各种翳障，眼科自有方法能够攻克。
【注】外障眼病：张子和说：眼睛不因为火邪就不会生病。所以五轮变红，气轮（白睛）发红，是火邪侵犯肺脏。肉轮（眼睑）发红，是火邪侵犯脾脏。风轮（黑睛）发红，是火邪侵犯肝脏。木轮（瞳孔）发红，是火邪侵犯肾脏。血轮（两眼角）发红，是火邪极盛所致。所以能治疗火邪，这一句就能解决所有问题。治疗火邪的方法：在药物方面，用咸寒性质的药进行催吐或泻下；在针灸方面，针刺神庭、上星、囟会、前顶、百会等穴位，翳膜可以使它立刻消退，疼痛可以使它立刻停止，视物昏暗可以使它立刻明亮，肿胀可以使它立刻消除。内障眼病：虽然也没有寒证，但是有虚证。虚证或者兼有热象，也属于虚热，所以不出现红肿疼痛，像没得眼病的人一样，只是眼神缺乏精彩和光明。心虚则神不足，神属火，火内里昏暗而外表明亮，所以不能对外界事物做出反应而失去光明。肾虚则精不足，精属水，水外里昏暗而内部明亮，所以不能向内滋养而失去光明。心虚的，就养护心神；肾虚的，就壮补肾水，自然可以在视力不明的问题上收到功效。那些由五风在内变化产生的各种翳膜，如圆翳、冰翳、清翳、涩翳、散翳、横翳、浮翳、沉翳、偃月翳、枣花翳、黄心翳、黑风翳等，都列在眼科书中，方书自有治疗方法，难以全部叙述，这里只是大概介绍罢了。
5. Externally obstructing eye diseases involve no cold syndrome, a point concluded in one sentence; the five wheels (referring to the pupil, cornea, canthi, sclera, and eyelids) turning red is due to the generation of fire pathogen. Internally obstructing eye diseases involve deficiency, specifically weakness of the Heart and Kidney; thus, the eyes appear as if unaffected by illness, yet their brightness is impaired. Fire serves as an external mirror, while Water illuminates internally; nourishing the Spirit (Shen) and strengthening Kidney Water will naturally yield results. Various opacities caused by the internal transformation of the Five Winds are readily treatable with specific ophthalmological methods.
[Annotation] Externally obstructing eye diseases: Zhang Zihe stated, "The eyes do not become diseased without the influence of Fire." Therefore, when the five wheels turn red: the Qi Wheel (sclera) reflects Fire invading the Lung; the Flesh Wheel (eyelids) reflects Fire invading the Spleen; the Wind Wheel (cornea) reflects Fire invading the Liver; the Wood Wheel (pupil) reflects Fire invading the Kidney; and the Blood Wheel (canthi) reflects excessive Fire. Thus, treating Fire resolves the issue in one step. Methods for treating Fire: Pharmacologically, use salty-cold herbs to induce vomiting or purgation; acupuncturally, needle Shenting (GV24), Shangxing (GV23), Xinhui (GV22), Qian Ding (GV21), and Baihui (GV20). Opacities can be made to recede immediately, pain to cease immediately, dimness to clear immediately, and swelling to dissipate immediately. Internally obstructing eye diseases: Although they also lack cold syndromes, they involve deficiency. Deficiency may accompany heat, constituting deficient-heat; thus, there is no redness, swelling, or pain. The eyes resemble those of a healthy person but lack luster and brightness. Heart deficiency leads to insufficient Spirit; since Spirit belongs to Fire, which is dim within but bright externally, it fails to reflect externally, resulting in loss of brightness. Kidney deficiency leads to insufficient Essence; since Essence belongs to Water, which is dim externally but bright internally, it fails to illuminate internally, resulting in loss of brightness. For Heart deficiency, nourish the Heart Spirit; for Kidney deficiency, strengthen Kidney Water, thereby restoring vision. Various opacities arising from the internal transformation of the Five Winds, such as Round Opacity (Yuan Yi), Ice Opacity (Bing Yi), Clear Opacity (Qing Yi), Rough Opacity (Se Yi), Scattered Opacity (San Yi), Horizontal Opacity (Heng Yi), Floating Opacity (Fu Yi), Sunken Opacity (Chen Yi), Crescent Moon Opacity (Yan Yue), Date Flower Opacity (Zao Hua), Yellow Center Opacity (Huang Xin), and Black Wind Opacity (Hei Feng), are all listed in ophthalmological texts. Standard formulas provide treatment methods, which cannot be exhaustively described here; this is merely a general overview.
