In the syndrome differentiation of six meridians in ophthalmology, generally speaking, Sanyang disease is more common in external barrier and Sanyin disease is more common in internal barrier. However, the understanding of external eye diseases is described in detail, and there is no detailed and in-depth discussion on internal eye diseases. Professor Chen Dafu, a famous ophthalmologist, put forward the theory that "intraocular tissues belong to viscera and meridians" according to the relevant theories in Neijing and the understanding of eye anatomy and physiology in modern medicine, which further improved the understanding of intraocular diseases and developed the theory of six meridians in ophthalmology. The content is as follows:

1, optic nerve, retina, iris, ciliary body and ciliary zonule belong to the liver meridian of foot jueyin. According to the "main fascia of liver" in Su Wen Wei Lun, the nerve belongs to the liver meridian of foot Jue Yin, and the optic nerve is inconvenient. As for retina, it is the sensory system of optic nerve, and it should also belong to Jueyin liver meridian. Iris (yellow brake) is the inner layer of wind wheel, and wind wheel is the Jue Yin liver in viscera; The zonule of ciliary head is connected with iris and belongs to the category of wind wheel, so it belongs to Jueyin liver meridian. The application of this theory to the treatment of optic nerve, retina, iris and ciliary body diseases and ametropia should start from Jueyin liver meridian. Such as acute optic neuropathy and acute optic neuritis, were treated with Longdan Xiegan Decoction at the initial stage. If it is caused by stagnation of liver qi, it can be treated with Danba Xiaoyao Powder. If it is weak and liver and kidney are insufficient, it can be treated with Zhu Jing Pill. Optic atrophy is mostly considered as deficiency of liver and kidney and loss of essence and blood, which can be treated with Zhu Jing Pill. Acute iridocyclitis, mostly caused by hepatobiliary inflammation, was treated with Longdan Xiegan Decoction. If heat enters the blood, it can be treated with rhinoceros horn and rehmannia decoction. Chronic iridocyclitis, mostly caused by residual heat of liver meridian, can be treated with abalone shell powder. It is believed that ametropia is caused by the disharmony of the liver meridian of foot Jue Yin and the unfavorable qi movement. Can be used for tonifying kidney and regulating liver. Commonly used "Neijing Jiawei Pill" treatment, supplemented by relaxing muscles and collaterals, such as? Knotted grass, etc.

2. Retinal macula belongs to the sun spleen meridian.

Based on Su Wenjin's theory that the central part is yellow and enters the spleen, Su Wenyin is yin and Yang Yingxiang is fragrant, the central part is wet, wet is sweet, sweet is spleen, wet is in the sky, the meat is in the body, the spleen is dirty and the color is yellow. The macular area of fundus is located in the center of retina and belongs to Taiyin spleen meridian. When macular lesions occur, they should start from Taiyin Spleen Meridian and the neck should be Jueyin Liver Meridian. For example, the pathological changes of meridian membrane of central retinal vein and macular congestion and edema caused by damp-heat of spleen meridian can be modified by Huanglian Wendan decoction; Wet weight is heavier than heat, Sanren decoction is added and subtracted; People with yin deficiency of liver and kidney can be treated with Dihuang Pill. Zhu Jing Pill can be used for patients with liver and kidney deficiency, and Liujunzi Decoction can be used for patients with spleen and stomach weakness. For those with spleen-stomach yang deficiency, add and subtract the five soups; The spleen meridian is wet, and I feel cold and dry. Treat with apricot, coix seed and licorice soup.

3. The choroid belongs to the heart meridian of Shaoyin.

According to Su Wen's Five Zang Roots, the heart governs the combination of veins, ten thousand veins return to the heart, and ten thousand veins return to the eyes, while Su Wen's theory of stomach governs the veins, so the choroid is composed of large, medium and small blood vessels, so each membrane belongs to the heart meridian of the hand with little yin. Clinically, Zhu Jing Pill can be used to treat the pathological changes of vein membrane and fundus blood vessels, because the heart meridian of hand is deficient, choroid is closely related to retina, and choroid and retinitis are related to heart, liver and kidney meridians.

4. Glass originally belongs to Taiyin Lung Meridian.

According to the record of "Lung Storing Soul" in the five qi articles of Su Wen Xuan Ming, vitreous body belongs to the lung meridian of hand Taiyin, and vitreous diseases mostly start from the lung meridian of hand Taiyin, such as liquefaction and turbidity of vitreous body, which are treated from lung, liver and kidney, supplemented by Shengmaisan and Astragalus, and liver and kidney are nourished with Qijudihuang Pill. After the operation of secondary retinal detachment or primary retinal detachment, it is considered that lung and kidney are deficient in qi, so Shengmai Powder, Ginseng and Astragalus are used to replenish vitality. If there is hydrops under the retina, it can be treated with warm water or with Jiawei Zhujing Pill.

5. Aqueous humor belongs to the gallbladder meridian of foot shaoyang.

According to Lingshu Tiannian, at the age of 50, liver qi began to decline, liver leaves began to wither, bile began to decrease, and the purpose began to be unknown. However, according to the health book, aqueous humor belongs to the gallbladder meridian with insufficient yang, and the pathological changes of aqueous humor should be treated from the gallbladder meridian with insufficient yin, such as turbid aqueous humor caused by excess heat of liver and gallbladder, and treated with Gentiana. If it is acute angle-closure green light, Chinese medicine believes that it is related to the obstruction of orifices by fire and the stagnation of spiritual water (aqueous humor). Add antelope horn with Longdan Xiegan decoction, or add and subtract with Chen Xifeng decoction. If vomiting and diarrhea are combined, Liuhe decoction can be used. Chronic angle-closure glaucoma is considered to be caused by internal movement of deficiency wind, so Shenshi Xifeng decoction is used to add and subtract. If the liver is depressed and the fire is flourishing, treat it with Danpa Xiaoyao Powder. If it is because of yin deficiency and fire flourishing, it should be treated with Baizhi Dihuang Pill.

6. All the pigments in the eyes belong to the kidney meridian of foot-shaoyin.

Use "Su Wen Wu Zang Gen Pian" and "Combination of Heart and Pulse"; Its brown color is also the basis of its main kidney. Pigment in eyes belongs to the kidney meridian of foot-shaoyin, and any pathological changes of pigment should be treated from the kidney meridian of foot-shaoyin. Such as choroidal pigment, syndrome differentiation from heart and kidney; Iris and ciliary body pigment should be treated from liver and kidney; Macular pigment should be treated from spleen, liver and kidney. In addition, pigment is a tangible thing and can be regarded as blood stasis. In the treatment, we should consider adding the product of promoting blood circulation and removing blood stasis. Retinitis pigmentosa is mostly congenital deficiency, so it is advisable to tonify kidney and liver, promote blood circulation and remove blood stasis. The treatment is mainly Zhu Jing Pill.

As the basic theory of ophthalmology, the theory of six meridians in ophthalmology has played a certain guiding role in the clinical practice of ophthalmology in traditional Chinese medicine. It gives full play to the advantages of simplicity, complexity, comprehensiveness and revealing the essence of eye diseases, and overcomes the limitations of disease naming. Moreover, it has many names, and the names are too thin to be used in clinic. Widely used in cataract eye diseases, but less used in cataract eye diseases. As a theoretical school, its scope of application is not very wide.
