Glaucoma is a common and irreversible eye disease characterized by increased eye pressure, optic nerve damage and visual field loss. Glaucoma damage to the optic nerve is insidious, often occurring unnoticed by the patient, and is easily overlooked by the patient, so it is called the “thief of vision”. The results of some population studies show that the key to glaucoma prevention and treatment is early detection, early diagnosis and early treatment to avoid glaucoma attacks as much as possible. More than half of the glaucoma cases are detected during screening. Therefore, screening for glaucoma is recommended for adults over the age of 40. Some people are more susceptible to glaucoma than others and are called “high-risk groups for glaucoma”, such as people with a family history of glaucoma, people with myopia and hyperopia, and people with endocrine diseases such as diabetes and thyroid disease. Systemic vascular disease. Especially people with low blood pressure; people with stressful work, irregular life, easy to lose temper, and high daily mood swings. These are the key targets in glaucoma screening. Glaucoma detected by screening requires drug, laser and surgical treatment, and the treatment plan should be determined by a professional physician. It is important to note, however, that glaucoma is a bilateral disease, only the onset of the disease may occur first or second. Therefore, if glaucoma is detected in one eye, the other eye should also be closely monitored or receive preventive treatment. Glaucoma should be treated according to medical advice and regular follow-up. You should not judge the condition based on whether your eye is swollen and painful. Some patients think that their eyes are no longer swollen and painful after medication and surgery, so they stop taking medication and do not go to the hospital for review.
