Glaucoma, as the second leading cause of blindness worldwide, poses a serious threat to human health. It is usually caused by damage to the optic nerve due to increased intraocular pressure. This disease mainly affects the optic nerve and visual field of the eye. If left untreated, it may lead to permanent visual impairment or even blindness.
1、 Symptoms of glaucoma
1. Decreased vision: Chronic glaucoma gradually affects vision and leads to blurred or decreased vision. The initial decline in vision may not be significant, but as the disease progresses, vision problems become more apparent; Acute glaucoma results in severe visual impairment, often dropping to an exponential level and even allowing only light to be seen.
2. Visual field defect: Glaucoma can cause visual field defect, that is, partial disappearance of the visual field. Initially, it may be a defect or blind spot in the peripheral visual field. As the disease progresses, the central visual field may also be affected, and patients may notice objects appearing blurry, missing, or appearing in dark areas.
3. Eye pain or discomfort: Some patients may experience eye pain, stinging, or discomfort, which may be related to elevated intraocular pressure or other eye problems caused by glaucoma.
4. Vision loss: If glaucoma is not treated for a long time or the treatment effect is poor, vision loss may occur. This is caused by prolonged increase in intraocular pressure leading to optic nerve damage, which is the main characteristic of glaucoma.
5. Strong light sensitivity: Associated with decreased vision, glaucoma patients may be sensitive to strong light, and when exposed to sunlight or strong light, they may experience glare, stinging, or discomfort in the eyes.
6. Difficulty adapting to dark environments: Glaucoma may affect patients' vision in dark environments, making it difficult for them to adapt to low light conditions or unable to see objects clearly at night.
2、 Prevention and treatment plan for glaucoma
1. Regular ophthalmic examination: Regular comprehensive ophthalmic examination, including measurement of intraocular pressure, visual field examination, optic nerve examination, etc., can help detect changes in glaucoma or disease early and take corresponding measures for management.
2. Reduce intraocular pressure: intraocular pressure is one of the main factors in glaucoma, and drug treatment is a common method to reduce intraocular pressure, such as eye drops (such as eye drops) or oral medication. Following the doctor's advice and using medication correctly and on time is an important part of managing glaucoma.
3. Avoid prolonged eye use and high intraocular pressure: Prolonged eye use, especially close eye use, may lead to elevated intraocular pressure and increase the risk of glaucoma. Therefore, maintaining appropriate eye rest time and avoiding elevated intraocular pressure are crucial for preventing and managing glaucoma.
4. Use medication with caution: Certain medications (such as steroids) may cause or worsen glaucoma. If there is a risk of glaucoma or if diagnosed with glaucoma, follow the doctor's advice and use medication with caution, especially long-term use of prednisolone hormones.
5. Control of related diseases: Some diseases, such as diabetes or hypertension, are related to the development of glaucoma. By controlling these diseases, seeing a doctor regularly and following the doctor's treatment plan, the risk of glaucoma can be reduced.
6. Surgical treatment: For patients who cannot control intraocular pressure through medication or whose vision is severely threatened, surgical treatment may be considered. The goal of glaucoma surgery is to reduce intraocular pressure, slow down disease progression, and protect vision.
7. Lifestyle and healthy habits: Maintaining a healthy lifestyle and good habits is crucial for preventing and managing glaucoma.
The symptoms and manifestations of glaucoma may vary among individuals. Some people may not have any obvious symptoms in the early stages of the disease and only realize their vision problems in the later stages. This emphasizes the importance of regular eye examinations, especially for those with a family history of glaucoma or other glaucoma risk factors. Early detection and treatment of glaucoma are key to preventing disease progression and protecting vision. If you suspect that you have glaucoma or related symptoms, please consult an ophthalmologist as soon as possible and receive professional diagnosis and treatment. Only through timely treatment and regular follow-up can the progression of glaucoma be controlled and vision be protected.
