Ophthalmology Information Glaucoma is a common blinding eye disease, divided into three categories: primary glaucoma, secondary glaucoma, and congenital glaucoma. Primary glaucoma is divided into closed-angle glaucoma and open-angle glaucoma. Glaucoma patients should not drink too strong tea Glaucoma is the second most blinding eye disease in the world and is an irreversible optic neuropathy. Elevated eye pressure and insufficient blood supply to the optic nerve are the two main factors that cause progressive damage to its optic nerve, which damages the visual field, not just the vision. The scary thing about glaucoma is that it is irreversible and insidious. Regular routine eye examinations are the most important method for early detection, and those at risk should be examined regularly. Only early detection and early diagnosis is the best way to avoid glaucoma blindness and obtain effective treatment. The hospital experts analyze the people who are prone to glaucoma, from infants to the elderly, can suffer from glaucoma at any age, but those who have the following conditions are more prone: 1, age over 40 years old; 2, high myopia; 3, diabetes; 4, family history of glaucoma; 5, hyperopia; 6, blood circulation disorders, excessive blood pressure fluctuations. It must be reminded that most patients have no obvious symptoms in the early stages; 90% of patients are not well aware of their disease and will only be discovered when they have lost more than 40% of their visual field. Early detection can be effectively treated Glaucoma diagnosis must not be judged by 1-2 tests alone, but must be combined with multiple tests, combined with medical history and comprehensive judgment to make an early and reliable diagnosis, thus providing a solid guarantee for further guiding treatment and preventing blindness. Most glaucomatous optic nerve damage is due to the increase in intraocular pressure caused by the obstruction of atrial circulation in the eye, which exceeds the limit of intraocular pressure tolerated by the optic nerve, thus causing slow progressive damage to the optic nerve. In other cases of glaucoma, although the IOP is normal, the structure of the optic nerve is weakened due to reduced blood flow to the optic nerve, resulting in impaired optic nerve function, which is called normal IOP glaucoma. Glaucoma is a lifelong disease that can worsen progressively and lead to blindness if not properly diagnosed and treated. Although it cannot be completely cured, it can be controlled by early detection and effective treatment. Stop or delay the ongoing damage to the optic nerve, prevent further visual field defects, and preserve existing visual function. Symptoms such as eye swelling and pain, iris and vision loss should be detected, and an eye examination should be conducted to rule out ophthalmic disease. It is not difficult to diagnose glaucoma in ophthalmology. There are three major manifestations: First, the intraocular pressure is significantly higher. In normal people, the intraocular pressure is 20 mm Hg, while in patients with glaucoma, the intraocular pressure reaches 50-80 mm Hg, and the eye is as hard as a stone when stroked with a finger. Second, there is the phenomenon of iridescence, which means that a colorful rainbow appears when looking at lights. Third, there is blurred vision, decreased visual acuity, corneal edema, and a foggy or hairy glassy appearance. The above conditions should be treated immediately after discovery to lower the eye pressure. However, medication can only temporarily relieve the symptoms and cannot stop recurrence. Therefore, appropriate surgery and related treatment should be performed promptly to save vision. The first thing is to anticipate and be prepared for the glaucoma “sound and fury” plan, especially for the elderly, when they have headache and brain rise, they should consider whether they have eye disease. Second, to identify in a timely manner, in the observation of physical symptoms, can not ignore the ophthalmic symptoms, after examination to detect the false, identify the “real” culprit, lift the danger. In addition to the doctor’s attention, patients themselves should also master the basic knowledge in this area. At the same time, we should pay attention to the protection of the eyes, especially at night do not overuse the eyes, do not watch TV for too long a continuous period of time, keep a relaxed mood, avoid impatience, anger, in order to prevent the occurrence of glaucoma.
