Chinese medicine calls droopy eyelids “lid wasting” or “sagging eyes”. The Yellow Emperor’s Classic of Internal Medicine, an ancient Chinese medical text, begins to document knowledge about drooping eyelids, discussing the anatomy, physiology, and pathology of the eye from the perspective of the internal organs, meridians, external evil, and internal injuries. Chinese medicine believes that there are three causes of droopy eyelids: 1. The joints, orifices and other organs of the body are bound by the zonous tendons, and when the zonous tendons are heated and the meridians are sluggish, the eyelids will lose their normal opening and closing function, and the patient will have symptoms of droopy eyelids or the inability to open the eyes. There are many meridians in the human body, but the ones most closely associated with the eyelids are the Foot Yang Ming Stomach Meridian and the Foot Sun Bladder Meridian. These two meridians are the meridians of qi and blood, and patients with myasthenia gravis have a deficient body and are unable to provide adequate qi and blood supply, and they also have a lot of deficiency heat and depression heat, so patients with myasthenia gravis tend to have symptoms of drooping eyelids. 2. The main impetus for the normal restraining function of the muscles and zonules comes from essence qi, and the eyes are one of the most exuberant tissues in the body. Therefore, deficiency of essence qi is one of the causes of droopy eyelids. The main function of the spleen is to transport water and grain, producing water and grain essence to moisten the body and replenish the essence of the internal organs; the spleen is responsible for raising the qing, which means transporting water and grain essence and essence from the internal organs to the eyes and all parts of the body. The spleen is responsible for the muscles, and the function of the levator muscle of the eyelids and the Muller muscle is closely related to the spleen. The Su Wen? In the book “The Spleen’s deficiency makes nine orifices inaccessible”, it is clear that droopy eyelids are closely related to the deficiency of the spleen. Professor Deng Tietao, a master of Chinese medicine, advocates the treatment of myasthenia gravis from the perspective of “deficiency of the spleen and stomach and the sinking of the atmosphere”. The eyes are the place where qi and blood are infused. Wind is a Yang evil and one of its main pathogenic characteristics is to invade the higher parts of the body. If the body’s blood is weak and the skin orifices are open and the wind evil is felt, the wind evil will invade between the lids and skin, causing the eyelids to not open and close properly. The most important way to produce qi and blood in the human body is through the normal daily diet, and the most important organ responsible for eating and producing qi and blood is the spleen and stomach. The treatment of drooping eyelids is complemented by “harmonizing and tonifying the Blood”. Therefore, the clinical treatment of myasthenia gravis is also based on “spleen deficiency and qi trapping, tonifying qi and blood”.
