障胡名逆顺，上下围将至。转瞬失风轮，瞳神憔悴矣。为治当如何，平肝滋肾水。既治了无功，固金参妙理。
此症风轮上下生翳，浓薄圆长不等，色昏白，赤脉周匝绊罩，朦胧多泪。盖虚风湿痰，滞瘀经络。滞于阴，
先发左目；滞于阳，先发右目；阴阳皆滞，左右齐发。睑不赤肿，珠无胀痛，亦不可轻视。若睛伤膏坏，头如棒
击，不能辨物者，又不知其变何症也。
轮廓天然成五色，五色昭明，守黑而知白。黑白有时不务德，黑翻为黄白翻赤。黑白难分名混一，轮廓未伤，
十病九痊得。但是年深药不的，夜光终始非灵璧。
此症皆一色昏白之障，轮廓无损。细视瞳子尚见，历久而不变，不治亦不愈。世之患者最多。其赤痛羞明，
眵结泪流，与他病同。病情及治法亦如之。间有障浓而实，浑似盐酥黑豆，丝缠而粗，恍若碎文磁钮，得效綦难。
浅人不知进退，药饵全无，惟以草以丹，且敷且点。不应，复手擦舌舐，挑耳根，炙臂膊，无所不至，非徒无益
而又害之。或病轻当愈，彼医适际其会，不自省悟，辄夸援为例，此不才之甚者也。更有令渠佩桃符，照水碗，
扎衣角者，真足喷饭。余承师训，参较有年，各症俱得其理。凡经手治，虽不神验，决无差误。然除刀针以外，
其所用药，不过宽郁、消痰、顺气、行血、滋阴、扶阳、疏风、降火等项，且人以艺高远游，非败症不果。延症
既败，多就补和处方。故病家咸以非专科药而疑之，不知药非专科，固专科之不能用也。正如倪迂晚年，灯下作
竹，傲然自得。晨起展视，全不似竹。迂笑曰∶全不似处，不容易到耳。可为解嘲。
障风（一种眼病）的别名是逆顺，其病变范围从上下方逐渐向中心蔓延。若不及时治疗，转瞬之间便会损伤黑睛（角膜），导致瞳神（瞳孔及晶状体等内部结构）出现憔悴衰败之象。
针对此症的治疗原则应当是：平抑肝阳，滋养肾水。如果常规治疗无效，则需采用固护肺气、用人参调理的妙理。
这种病症表现为黑睛上下生出翳膜，翳膜厚薄、形状（圆形或长形）各不相同，颜色呈昏白色，周围有赤色血脉环绕包裹，视物朦胧且多泪。其病因多为虚邪、风湿、痰浊阻滞经络。病气滞留在阴分，首先发作于左眼；滞留在阳分，首先发作于右眼；若阴阳皆受阻滞，则双眼同时发病。眼睑不红肿，眼球无胀痛感，但也不可轻视。如果眼睛受损、神膏（玻璃体等）败坏，头痛如被棒击，无法辨别物体，那就不知道会演变成什么病症了。
人的眼部轮廓天生具备五色（青赤黄白黑），五色分明，坚守黑色（瞳仁）而知晓白色（巩膜）。但如果黑白不分，违背医德（此处指违背生理常态或治疗原则），黑色翻转为黄色，白色翻转为红色。若黑白难分称为“混一”（即混睛障），只要轮廓未受损伤，十种病例中有九种可以痊愈。但是如果病程长久，用药不准，即便使用名贵的夜光丸等药，最终也非灵璧石所能替代（意指难以治愈）。
这种病症都是单一颜色的昏白色翳障，眼部轮廓没有损坏。仔细观看瞳孔尚可见到，经过很长时间也不改变，不治疗也不会自愈。这是世间患者最多的眼病之一。其伴有赤痛、羞明（畏光）、眼屎结块、流泪等症状，与其他眼病相同。病情发展及治疗方法也类似。偶尔有翳膜浓密坚实者，浑似盐酥黑豆，丝线缠绕且粗糙，恍若破碎的磁钮，想要取得疗效非常困难。
浅薄无知的人不懂进退之道，完全不使用正规药物，只用草药或丹药，既外敷又点眼。如果不见效，又用手擦、用舌舔，挑耳根，灸臂膊，无所不用其极，这不仅无益反而有害。或者病情轻微本应自愈，恰好遇到庸医碰巧治好了，他不自我反省醒悟，反而夸耀自己援引先例，这是极其无才的表现。更有甚者，让病人佩戴桃符（辟邪之物），对着水碗照看，扎衣角等迷信做法，真是令人喷饭。
我继承老师的教诲，参考比较多年，对各种病症的道理都已掌握。凡是我经手治疗的，虽然不敢说神效，但决无差错。然而除了刀针手术以外，我所使用的药物，不过是疏解郁结、消除痰浊、理顺气机、活血行血、滋阴、扶阳、祛风、降火这几类，而且人们凭借技艺远游四方，如果不是败症（晚期重症），通常不会轻易延请。一旦病症已经败坏，大多采用补益调和的处方。所以病家常常怀疑我不是专科医生开的药，却不知道正因为不是专科医生的药，才是专科医生无法使用的（指通用辨证施治优于刻板专科）。正如倪瓒（倪迂）晚年，在灯下画竹，傲然自得。早晨起来展开观看，完全不像竹子。倪瓒笑着说：“完全不像的地方，正是别人不容易达到的境界。”这可以作为自我解嘲的话。
The disease known as "Zhang" (opacity) is also named Ni Shun (Reverse and Smooth). Its progression encircles from the upper and lower aspects. In a fleeting moment, it may damage the Wind Wheel (cornea), leading to the emaciation and deterioration of the Tong Shen (pupil and internal ocular structures).
How should it be treated? One must calm the Liver and nourish Kidney Water. If treatment yields no merit, one must adhere to the profound principle of consolidating Metal (Lung) and using Ginseng.
This condition manifests as an opacity growing on the upper and lower parts of the Wind Wheel. The opacity varies in thickness, shape (round or elongated), and color (dull white). It is surrounded by red vessels that wrap around and cover it, causing blurred vision and excessive tearing. The etiology involves deficiency, wind-dampness, and phlegm stagnating in the meridians. Stagnation in Yin causes onset in the left eye first; stagnation in Yang causes onset in the right eye first; if both Yin and Yang are stagnant, both eyes erupt simultaneously. The eyelids are not red or swollen, and the eyeball lacks distending pain, yet this should not be taken lightly. If the eye is damaged and the Shen Gao (vitreous humor/ocular essence) is ruined, accompanied by headache like being struck by a club and inability to distinguish objects, it becomes impossible to predict what other disease it might transform into.
The contour of the eye is naturally formed with five colors. When these five colors are distinct, one guards the Black (pupil) and knows the White (sclera). However, when Black and White fail to maintain their virtue (normal state), Black turns Yellow and White turns Red. When Black and White are indistinguishable, it is named Hun Yi (Mixed Clarity/Mixing Eye Opacity). If the contour remains undamaged, nine out of ten cases can be cured. But if the disease persists for years and medication is inaccurate, even Night-Luminous Pills (Yeguang Wan) will not be effective, nor will Lingbi Stone suffice.
This condition consists entirely of a single-color dull-white opacity, without damage to the ocular contour. Upon close inspection, the pupil is still visible. It persists unchanged over a long period; without treatment, it neither heals nor worsens. This is the most common ocular disease among patients in the world. Symptoms such as redness, pain, photophobia, discharge accumulation, and tearing are identical to other diseases. The progression and treatment methods are also similar. Occasionally, there are cases where the opacity is dense and solid, resembling salt-crisped black beans, with coarse, thread-like entanglements, looking like broken porcelain buttons. Achieving efficacy is extremely difficult.
Superficial individuals do not know when to advance or retreat. They use no medicinal decoctions, relying solely on herbs or alchemical pills, applying them externally and instilling them internally. When ineffective, they resort to rubbing with hands, licking with tongues, picking ear roots, and moxing arm pits, going to any extreme. This is not only useless but harmful. Or, if the disease is mild and would heal spontaneously, a mediocre doctor happens to treat it successfully at that moment. Without self-reflection, he boasts of citing precedents, which is the height of incompetence. Even more absurd are those who prescribe wearing peach wood charms, gazing into water bowls, or tying corners of clothes—practices truly worthy of laughter.
I inherited my master's teachings and have studied and compared various texts for many years, grasping the principles of each condition. Although my treatments may not be miraculous, they are certainly error-free. Apart from surgical needle techniques, the medications I use generally include those that relieve depression/stagnation, resolve phlegm, regulate Qi, promote blood circulation, nourish Yin, support Yang, dispel wind, and descend fire. Furthermore, physicians travel far with their skills; unless it is a terminal case, they do not easily accept patients. Once the disease has become terminal, prescriptions mostly focus on tonification and harmonization. Therefore, patients often suspect that because the medicine is not from a specialist, it is inferior. They do not realize that precisely because it is not restricted to a specialist's narrow scope, it utilizes methods that specialists cannot apply. Just as Ni Zan (Ni Yu) in his later years painted bamboo under lamplight, feeling proud and content. In the morning, upon unrolling the painting, it looked nothing like bamboo. Ni Zan laughed and said, "The places where it looks nothing like bamboo are exactly where others find it hard to reach." This serves as a good excuse for self-mockery.
