According to data released by the World Health Organization, glaucoma is the second leading cause of blindness globally, second only to cataracts. It is expected that the global number of glaucoma patients will reach 95.4 million by 2030 and 112 million by 2040. China's glaucoma patients account for one fourth of the global total. People generally have a basic understanding of cataracts, but there are many misconceptions and blind spots in their understanding of glaucoma. 90% of patients are unaware that they have glaucoma, and have never heard of it before. By the time they are discovered, they are already in the middle and late stages. When it comes to nearsightedness, farsightedness, and presbyopia, most people are familiar with them. But when it comes to glaucoma, people know very little about it. Many people's first reaction is' this is a disease that only elderly people will get ', but in fact, it is not. With the popularization of electronic products, glaucoma has gradually shown a younger trend in recent years. Many young people watch their computers while working, swipe their phones and watch TV after work, and long-term excessive eye use brings great burden to their eyes. In addition, factors such as accelerated pace of life, high stress, and emotional fluctuations can also easily lead to eye fatigue, increasing the likelihood of developing glaucoma. I thought it was a deepening of myopia, but it turned out to be glaucoma. Ms. Zhou, 32 years old, had high work intensity and often worked overtime. Recently, she often felt discomfort in her eyes and couldn't see clearly even after wearing glasses. I thought her myopia had increased again, so I went to the hospital for medical treatment. After examination by the doctor, it was found that the intraocular pressure in his left eye reached 25mm Hg (normal value 10-21mm Hg). Further examination showed that the visual field of his left eye was damaged, and he was diagnosed with primary open angle glaucoma. The doctor stated that due to Ms. Zhou's timely treatment and early stage of the disease, appropriate use of eye pressure lowering medication can control her condition. If not treated in a timely manner, the condition will gradually worsen, leading to irreversible visual impairment. Literally, "glaucoma" can easily be misunderstood as seeing things blue, but in reality, it is just a diagnostic term. Before understanding glaucoma, it is important to first clarify two concepts: intraocular pressure and the optic nerve. Intraocular pressure refers to the pressure exerted by substances inside the eyeball on the eyeball wall. Among them, one important substance that affects intraocular pressure is aqueous humor. The optic nerve is located at the back of the eyeball and conveys visual information seen by the eyes to the brain. If the intraocular pressure increases, it may compress the optic nerve and cause a decrease in vision. For a more general explanation, doctors also compare glaucoma to "blockage of the eye's' sewer '. The "sewer" in the eyes is called "Fang Jiao" in Chinese; The water in the eyes is called "room water". The vast majority of aqueous humor is discharged from the eyes through the corners of the room. If the discharge of aqueous humor is obstructed, the pressure inside the eyes will increase, just like if we block the opening of the water pipe with our fingers, the pressure inside the water pipe will increase. Once the intraocular pressure exceeds a certain limit, it will compress the optic nerve, causing optic nerve atrophy and visual function damage. Glaucoma is mainly related to an increase in intraocular pressure. Its essence is due to an abnormal increase in pressure in the eyeball, which causes damage to the retina and optic nerve tissue and ultimately leads to visual dysfunction. The visual dysfunction of glaucoma manifests as gradual damage, loss, or narrowing of the field of vision, ultimately disappearing. As far as current medicine is concerned, the sight of the gods
