Glaucoma is a common eye disease in middle-aged and elderly people. It can be manifested as an increase in intraocular pressure, causing damage to eye tissue, especially the optic nerve; or it can be manifested as a decrease in blood flow to the eye without high intraocular pressure, causing damage to the optic nerve and eventually affecting visual function and leading to blindness. Because optic nerve damage is irreversible once it occurs, even after treatment, the damaged visual function cannot be restored, making glaucoma a serious blinding eye disease. Glaucoma is a common eye disease that can occur at any age, and its incidence increases with age. The average prevalence in people over 40 years of age is 1 to 2 percent. Glaucoma is a lifelong and progressive disease. It does not heal or stop on its own, and if left to its own devices, it will continue to progress until blindness sets in. Different types of glaucoma have different clinical manifestations. In the acute attack of acute closed-angle glaucoma, the intense symptoms and unbearable pain cause patients to seek medical attention mostly in time because of the rapid increase in intraocular pressure; while other glaucomas progress in a hidden and slow manner, the eyes are neither red nor painful in the early stage of the disease, and there is no obvious change in vision, so many people in the population know nothing about their glaucoma disease, so glaucoma is called the thief that causes blindness. A small number of people experience mild eye swelling, visual fatigue, blurred vision, and occasional rainbow vision, which improves with rest and no significant decrease in visual acuity. Therefore, it is also often overlooked and medical attention is delayed. When the disease progresses to the middle and late stages, patients gradually have blurred vision or feel a narrowing of the visual field, and their work and life are affected before they go to the hospital for examination, when the damage to the optic nerve of glaucoma is already very serious. These unknowingly developed glaucoma are more dangerous than acute onset glaucoma, so it is important to be vigilant about this. Glaucoma is incurable, so the key to glaucoma treatment is early treatment, and the prerequisite is early detection and diagnosis. Only in the early stages of glaucoma, when the damage to the optic nerve is very mild or not severe, can the treatment yield better results. Therefore, those who have the following conditions should go to the hospital for glaucoma exclusion tests as soon as possible for early detection of glaucoma 1.People who are suspected of having glaucoma in physical screening. after the age of 40, eye pressure and fundus must be checked regularly every year. 2.People with family history of glaucoma. Every family member should be carefully examined once and do long-term regular observation if necessary. 3.One eye is diagnosed with glaucoma, and the other eye should be examined as early as possible. 4, suffering from systemic diseases related to glaucoma, such as diabetes, hypertension, hypotension, hyperlipidemia, etc. 5, suffering from other eye diseases related to glaucoma, such as high myopia, high hyperopia and fundus bleeding. 6.Present with common symptoms of glaucoma: eye swelling, headache, rainbow vision, vision loss, etc. People with the above high-risk factors do not necessarily have glaucoma, but the absence of signs of glaucoma on the initial examination does not guarantee that glaucoma will not occur in the future, so they should still be followed up regularly according to the advice of their ophthalmologist. Once glaucoma is diagnosed, it should be treated immediately. The goal of treatment is to reduce intraocular pressure, prevent further damage to the optic nerve, and protect visual function. Treatment includes medication, laser therapy and surgery. Treatment options vary for different types and stages of glaucoma, and the doctor will recommend a specific treatment plan for each patient.
