Glaucoma is the first irreversible blinding eye disease in China. Foster et al. hypothesized, based on epidemiological findings in Singapore and Mongolia, that there are about 405 million people over the age of 40 in China, of whom 9.4 million have glaucomatous optic nerve damage, 5.2 million are blinded by glaucoma in one eye, and 1.7 million are blinded by glaucoma in both eyes. The number of people blinded by glaucoma in one eye is 5.2 million and 1.7 million in both eyes. The results of the 1996 epidemiological survey of glaucoma among people aged 50 and above in Shunyi District, Beijing, showed that the prevalence of glaucoma was as high as 2.1%, 64% of glaucoma patients had some degree of visual impairment, and the rate of binocular blindness was 16.0%. The rate of double blindness was 16.0%. This result is compared with the epidemiological findings of glaucoma in the same region in 1985, although the level of glaucoma diagnosis and treatment has improved significantly after 10 years, the blindness rate of primary glaucoma has increased from 9.3% to 16.0%, thus further warning us of the seriousness and complexity of the glaucoma prevention and treatment problem. Global data on blindness and visual impairment published by the World Health Organization in 2004 showed that glaucoma is the second leading cause of blindness after cataract, accounting for 12% of all blind people. Since cataracts can be treated surgically to restore visual function, it is especially important to prevent and treat glaucoma, an irreversible blinding eye disease. Early detection and treatment are especially important for glaucoma patients. If damage to visual function has already occurred, the damaged portion cannot be restored, but with proper treatment and regular follow-up, monitoring and adjustment of the treatment plan in cooperation with the patient and the doctor, visual function can be maintained and useful vision can be maintained throughout life. In order to achieve this goal, it is very important to popularize the knowledge about glaucoma, especially glaucoma patients and their family members should have more knowledge about how to adjust their mentality and cooperate with the examination and treatment, I would like to be a friend of glaucoma patients, to help you solve your problems, answer all kinds of questions, help glaucoma patients to establish confidence in treating the disease, and become your lifelong friend.
