问曰∶左赤传右何也？答曰∶此阴经火热也。阳中行阴肝也，阴中行阳心也，邪热攻积于肝也，肝邪交于心，

【不赤而痛图】
问：人患眼病，既不瘙痒也不发红却感到疼痛，这是什么原因？答：这是气脑虚弱所致，营卫不和，气血凝滞也可能导致这种情况。七情郁结，肝风上冲，脑中风气相互攻冲，所以出现不痒、不红而疼痛的症状。初发病时应当急服药物，恐怕会转变为五风内障（一种难治的眼科疾病），那就难以治疗了。适宜服用透红匀气散、川芎散、助阳和血汤。
透红匀气散
当归、细辛、白芷、没药、泽兰、甘草、茴香、天仙藤、浓朴、乳香、肉桂、黑牵牛、生地黄、羌活（各一两）
以上药材研为细末，每次服用三钱，用热酒调服。
川芎散
川芎、菊花、细辛、鼠粘子（牛蒡子）、石膏、僵蚕、蒺藜（各一两）
以上药材研为细末，每次服用二钱，用米汤送服。
【赤而不痛图】
问：人患眼病，发红却不感到疼痛，这是什么原因？答：这是肝热所致。膀胱涩滞且排尿不利，心火炎上。人身之血如同河流沼泽的水流，如果川泽疏通，水流必然汇入大海；如果膀胱壅塞，洪水就会妄自流淌。人的血液顺畅则经络流利，上下相接，周而复始；如果血液逆乱则散漫妄行，向上灌注于眼睛，所以出现发红却不疼痛的症状。现在膀胱不利，心火上炎，肝经实热，这难道不像川泽壅塞一样吗？治疗时必须使用八正散、导赤散、顺肝丸服用。
八正散、导赤散
顺肝丸
黄连、黄芩、当归、蕤仁（三十粒）
以上药材共同研为细末，用炼蜜制成丸剂。
【左赤传右图】
问：左眼发红传染到右眼，这是什么原因？答：这是阴经火热所致。阳中运行着阴，肝属此类；阴中运行着阳，心属此类。邪热积聚在肝脏，肝邪波及心脏，进而传至眼睛。左眼属于太阳经，右眼属于太阴经，所以左眼发红传染到右眼，是因为太阳经旺盛的缘故。适宜服用三黄丸、洗心散。
[Figure: Pain Without Redness]
Question: Why do some people suffer from eye disease characterized by pain without itching or redness? Answer: This is caused by deficiency of Qi and the brain, disharmony of Ying (Nutritive) and Wei (Defensive) Qi, and stagnation of Qi and Blood. Stagnation of the Seven Emotions, with Liver Wind rushing upward, and conflict between Wind Qi in the head, result in pain without itching or redness. At the onset, urgent medication should be taken to prevent transformation into Wufeng Neizhang (Five Winds Internal Cataract), which is difficult to treat. It is appropriate to administer Touhong Yunqi San (Red-Permeating Qi-Regulating Powder), Chuanxiong San (Ligusticum Powder), and Zhuyang Hexue Tang (Yang-Assisting and Blood-Harmonizing Decoction).
Touhong Yunqi San (Red-Permeating Qi-Regulating Powder)

Zhuyang Hexue Tang (Yang-Assisting and Blood-Harmonizing Decoction)
[Figure: Redness Without Pain]
Question: Why do some people suffer from eye disease characterized by redness without pain? Answer: This is due to Liver Heat. The Bladder is astringent and urination is difficult; Heart Fire is blazing. The blood in the human body is like the flow of rivers and marshes. If the channels are clear, the water flows into the sea; if the Bladder is obstructed, floodwaters flow recklessly. When human blood flows smoothly, the meridians are unobstructed, connecting up and down in a continuous cycle; when it flows reversely, it scatters and acts recklessly, pouring upward into the eyes, resulting in redness without pain. Now, with Bladder dysfunction, Heart Fire flaming upward, and excess heat in the Liver channel, is this not analogous to the obstruction of rivers and marshes? Treatment requires the use of Bazheng San (Eight-Normality Powder), Daochi San (Guide Out Redness Powder), and Shun Gan Wan (Liver-Soothing Pill).
Bazheng San (Eight-Normality Powder), Daochi San (Guide Out Redness Powder)
Shun Gan Wan (Liver-Soothing Pill)
Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Danggui (Angelicae Sinensis Radix), Ruiren (Pruni Armeniaci Semen Amarum) (30 grains).
Grind the above herbs together into powder, and form pills with refined honey.
[Figure: Left Redness Spreading to Right]
Question: Why does redness in the left eye spread to the right eye? Answer: This is due to Fire-Heat in the Yin channels. Yang contains Yin operation, which corresponds to the Liver; Yin contains Yang operation, which corresponds to the Heart. Pathogenic heat accumulates in the Liver; Liver pathogen interacts with the Heart and transmits to the eyes. The left eye belongs to the Taiyang (Greater Yang) channel, and the right eye belongs to the Taiyin (Greater Yin) channel. Therefore, left redness spreads to the right because the Taiyang channel is vigorous. It is appropriate to administer Sanhuang Wan (Three-Yellows Pill) and Xixin San (Heart-Washing Powder).
Sanhuang Wan (Three-Yellows Pill) (Add Huangbai [Phellodendri Cortex] if heat is severe)
Xixin San (Heart-Washing Powder)
Dahuang (Rhei Radix et Rhizoma), Chishaoyao (Paeoniae Radix Rubra), Danggui (Angelicae Sinensis Radix), Gancao (Glycyrrhizae Radix et Rhizoma), Jingjie (Schizonepetae Herba), Mahuang (Ephedrae Herba), Zhizi (Gardeniae Fructus) (each 1 liang).
Take equal parts of each herb, decoct in water, and take orally.
