Glaucoma is one of the most common blindness-causing eye diseases in clinical practice, among which primary closed-angle glaucoma and primary open-angle glaucoma are the most common. With the advent of an aging society and the increasing sophistication of various ophthalmic examination instruments, the clinical incidence of primary open-angle glaucoma has increased significantly compared to the past, and according to statistics, it is now clinically comparable to the incidence of primary closed-angle glaucoma. The anterior space of our eye, separated by the iris into the anterior and posterior chambers, are filled with fluid continuously secreted by the ciliary body epithelium – atrial fluid, which, after participating in intraocular metabolism, is mainly discharged by some tiny tubes at the anterior chamber angle. Primary closed-angle glaucoma is caused by the blockage of these tiny ducts, which affects the discharge of atrial fluid, thus causing an increase in intraocular pressure, which compresses the retina and optic nerve and causes damage to visual function (vision and visual field). In primary open-angle glaucoma, the ducts are open and unobstructed, but there is aging and stagnation inside the tiny ducts, which affects the drainage of atrial aqueous, causing an increase in intraocular pressure and damage to visual function. Treatment for primary closed-angle glaucoma is primarily surgical, creating new channels for atrial fluid drainage and lowering intraocular pressure. Western medicine treatment for primary open angle glaucoma firstly considers eye drops to reduce atrial aqueous production or enhance atrial aqueous metabolism, and nowadays surgery, including laser treatment, is also increasingly used to create new atrial aqueous drainage channels to reduce IOP. Generally speaking, through eye drops or surgical treatment, it is possible to achieve the effect of lowering IOP, that is, to reach the “target IOP” range. Normal IOP is generally between 10 and 21 mmhg, and the “target IOP” is to lower it as much as possible within the normal IOP range to reduce the pressure in the eye and protect the function of the optic nerve and retina. However, clinically, primary open-angle glaucoma is not easy to detect early, because our eyes are often not red and painful, and when we feel unclear vision and come to the clinic, there is often a certain amount of damage to vision and visual field, and often to the middle or even late stage. The cause of the disease is, on the one hand, the aging of the tiny drainage ducts, and on the other hand, recent studies have proven that these patients have “aging” pathological changes inside the eye, i.e., there is a significant degeneration of certain tissues inside the eye, which is called “apoptosis” in modern medical terminology. The modern medical term for this is “apoptosis”. Therefore, in some patients with primary open-angle glaucoma, although the IOP can be controlled within the “target IOP” range through IOP-lowering eye drops or surgery, the “aging” changes in the eye cannot be stopped, and the vision and visual field are further impaired. The damage is considered by Western medicine to be largely irreversible. Western medicine considers this damage to be largely irreversible. What role can Chinese medicine play in the treatment of primary open-angle glaucoma? Through years of clinical observation, based on western medicine’s treatment of lowering IOP, the use of Chinese medicine intervention can improve the visual field of more than 60% of patients, breaking the modern medical view that the visual field damage of primary open angle glaucoma patients is basically irreversible and improving the quality of life of patients. In addition, Chinese medicine can also be used to interrupt or slow down the process of “aging” in the eye and prevent further damage to visual function. Anti-aging and anti-aging have always been the strength of TCM.
