又有气眼。才怒气则亦痛。宜服酒调复元通气散。
又有头风眼。偏正头痛。眼不可开。多泪羞明。宜决明散。
治疗眼病。用青桑树的干枝，在坚硬的炭火上烧取白色的灰烬。用铜制的筷子蘸取药灰点入眼中，每日二至三次，效果极佳。不可使用水桑、黄桑的枝条，也不可混杂普通的炭灰。
眼病的种类不一，如眼睑溃烂、恶露羞明、白膜遮睛、涩痛、雀目（夜盲症）、韬针（畏光刺痛）、内障、外障等证候，难以一一列举。现在仅列举几种赤眼（红眼）的情况。凡是患有眼病的人，不论病程长短，上述各种证候均可使用四物汤，并服用生熟地黄丸，敷洗类的药剂应当咨询专科医生。在四物汤中加入一块蒸熟的大黄，大小如栗子，尤为巧妙。
有因长时间用眼导致眼睛受损，肝血不足，以致视物不明，眼中常感觉有烟焰升起。这种情况应当补血，适宜服用生熟地黄丸。
有因长期吃素导致目光暗淡，或形成雀目。因为食物能化生精气，精气亏损则眼睛失去滋养而视力减退。
眼疾的各种证候，医生们多使用治眼流气饮进行治疗，这属于专门的眼科领域。寻常的赤眼可用黄连研成粉末，先取一个大莱菔（萝卜），切去顶部作为盖子，挖空中心形成一个孔洞，将黄连末放入其中，再用盖子盖住，用竹签固定，在慢火中煨熟后取出，待冷却后将萝卜中的汁水滴入眼中。
赤眼有好几种类型，如气毒引起的赤眼、热壅引起的赤眼、有时发作的眼赤等，无非都是血壅滞于肝经所致。因为肝主藏血，开窍于眼。赤眼之病，大率都源于肝脏。可将黑神散与消风散按相等分量混合，用白开水调服，饭后及睡前服用。同时用豆腐切片敷在眼部，盐渍过的豆腐可以使用，酸浆豆腐则不可使用，这即是乌豆敷眼的用意。
若属风热，且红肿严重，则在黑神散和消风散这两种药中，增加消风散的用量。间或用稀释的米泔水，在睡前用冷调洗肝散或菊花散清洗并服用。同时继续服用四物汤，其中的地黄用生地黄，芍药用赤芍，只需半帖的量，饭后分一次服完。随后加入赤茯苓半钱，以及醉将军（即酒蒸大黄）。早晨用盐汤送服养正丹二十至三十粒。
如果不适宜使用过于寒凉的药剂，则不必使用洗肝散。宜用二钱黑神散，一钱消风散。
如果赤眼日久不愈，使用各种眼药均无效，早起时服用苏子降气汤，并吞服黑锡丹；临睡前服用消风散，并吞服三黄丸；中午另外用酒调服黑神散。这几类药物不仅治疗久治不愈的红眼，各种眼疾皆可治疗。
如果眼前出现晕圈或飞花现象，则属于肝虚，应当在虚损门的眩晕证候中寻找药物。或者是由于其他疾病导致出现眼花症状，应结合所患的其他疾病随证施治。
Treating eye diseases. Burn the dry branches of green mulberry trees over hard charcoal fire to obtain white ash. Dip copper chopsticks into the ash and apply to the eyes two or three times; this is highly effective. Do not use branches from water mulberry or yellow mulberry, nor mix in ordinary charcoal ash.
Eye diseases vary greatly, including conditions such as eyelid ulceration (Lanyan), aversion to light and discharge (Eman Xiuming), leukoma obscuring vision (Yimo), astringency and pain (Se Tong), night blindness (Que Mu), photophobia with stinging pain (Tao Zhen), internal cataract (Nei Zhang), and external cataract (Wai Zhang), among others, which are too numerous to list exhaustively. Here, only several types of red eye (Chi Yan) are presented. For those suffering from any eye disease, regardless of whether it is chronic or recent, the above-mentioned conditions can be treated with Siwu Tang (Four Substances Decoction), accompanied by Shengshu Dihuang Wan (Raw and Cooked Rehmannia Pill). Applications and washes should be sought from specialized practitioners. Adding a piece of steamed Rhizoma Rhei Preparatum (Zheng Da Huang), sized like a chestnut, to Siwu Tang is particularly excellent.
Prolonged visual strain damages the eyes, leading to insufficiency of Liver Blood, resulting in blurred vision and a sensation of smoke or flames rising within the eyes. This condition requires nourishing blood, for which Shengshu Dihuang Wan is suitable.
Long-term vegetarianism may lead to dim vision or night blindness. Since food generates essence, its deficiency deprives the eyes of nourishment, reducing clarity of sight.
For various eye conditions, physicians often employ Zhiyan Liuqi Yin (Eye-Regulating Qi-Flowing Drink), which falls under specialized ophthalmology. For common red eye, grind Coptidis Rhizoma (Huanglian) into powder. Take one large Radish (Laitao), cut off the top to serve as a lid, hollow out the center to create a cavity, insert the Huanglian powder inside, replace the lid, secure it with bamboo skewers, and slowly roast over low heat until cooked. Remove, let cool, and drip the juice from the radish into the eyes.
Red eye presents in several types: those caused by Qi toxicity, those caused by Heat stagnation, and those that occur intermittently. These are all essentially due to Blood stagnation in the Liver Meridian, as the Liver stores Blood and opens into the eyes. Red eye pathology generally stems from the Liver. Mix Heishen San (Black Divine Powder) and Xiaofeng San (Wind-Expelling Powder) in equal proportions, take with warm water after meals and before sleep. Additionally, apply slices of tofu to the eyes; salted tofu is acceptable, but fermented sour tofu is not. This corresponds to the principle of applying black soybeans to the eyes.
If the condition involves Wind-Heat with severe redness, increase the proportion of Xiaofeng San relative to Heishen San. Occasionally, rinse the eyes with diluted rice water at bedtime using cold Ligan San (Liver-Washing Powder) or Juhua San (Chrysanthemum Powder) for both washing and oral administration. Continue taking Siwu Tang, using raw Sheng Dihuang (Raw Rehmanniae Radix) and Chi Shao (Red Peony Root), taking only half a dose, administered once after meals. Then add Ban Qian of Chufeng Fuling (Polyporus with Red Dye) and Zuì Jiāngjūn (Jiu Zheng Dahuang, i.e., Rhizoma Rhei prepared with wine). In the morning, take 20–30 pills of Yangzheng Dan (Upright-Qi Preserving Pill) with salt water.
If overly cooling agents are unsuitable, Ligan San need not be used. Instead, use two qian of Heishen San and one qian of Xiaofeng San.
If red eye persists without cure and various eye medications prove ineffective, take Suzi Jiangqi Tang (Perilla Seed Descending-Qi Decoction) upon waking, followed by Heixi Dan (Black Tin Pill). Before sleep, take Xiaofeng San followed by Sanhuang Wan (Three Yellows Pill). At noon, take Heishen San mixed with wine. These medicines treat not only chronic red eye but various other eye diseases.
If visual halos or floaters appear, this indicates Liver Deficiency. Seek remedies from the section on Deficiency Syndromes regarding vertigo/dizziness. Alternatively, if floaters result from another primary illness, treat according to the specific diagnosis of that underlying condition.
There is also "Qi Eye," characterized by pain immediately following anger. This is suitable for treatment with Jiutiao Fuyuan Tongqi San (Alcohol-Mixed Restoring Circulation and Unblocking-Qi Powder).
There is also "Headwind Eye," presenting with unilateral or central headache, inability to open the eyes, excessive tearing, and photophobia. Mingmu San (Clear-Vision Powder) is appropriate.
