What causes glaucoma and how is glaucoma caused?

Glaucoma is mainly caused by an increase in intraocular pressure. Aqueous humor is produced in the eyeball from the ciliary process, and the aqueous humor passes through the pupil and exits through the trabecular meshwork of the anterior chamber angle to maintain stable intraocular pressure. When the flow of aqueous humor is blocked due to various reasons, the intraocular pressure will rise, compressing the optic nerve and causing permanent damage to the optic nerve.

Glaucoma**.

1. Anatomical causes: short eye axis, shallow anterior chamber, thick lens, and small corneal diameter, resulting in narrow anterior chamber angle, obstruction of aqueous humor discharge, increased intraocular pressure, and glaucoma formation.

2. Age and gender: open-angle glaucoma is more common around 30 years old, and the risk of high myopia is increased, and there is no obvious gender difference. Among the patients with angle-closure glaucoma, 68 2%-76 8% of glaucoma patients over 45 years old are over 45 years old, and more women than men.

2. Systemic diseases: especially diabetes, can cause diabetic retinopathy, followed by neovascular glaucoma.

3. Medication causes glaucoma, the common one is hormonal glaucoma, whether it is local or systemic hormones, such as ** disease, arthritis, immune system diseases need to be used for a long time, intraocular pressure must be measured regularly. In addition, patients who need to take hormonal eye drops must have their intraocular pressure measured regularly.

In particular, it is important to note that many patients with chronic conjunctivitis experience long-term use of hormonal eye drops without the guidance of a doctor, causing hormonal glaucoma, which causes hormonal glaucoma, and the intraocular pressure of this type of glaucoma rises slowly and most of them have no symptoms.

4. Glaucoma caused by genetic causes: glaucoma is a polygenic hereditary lesion, and the incidence rate of those with family history is 6 times higher than that of those without family history, accounting for 13%-47% of the entire number of patients, and the incidence rate of patients' relatives is 3 5%-16%.

Glaucoma is due to mental factors, which can easily induce diseases and lead to physical discomfort due to prolonged exposure to stressful environments. You can actively regulate your emotions in your life, so that the problems of tension and anxiety can be relieved, so as to reduce the incidence of glaucoma.

2.In life, many people will think that smoking and drinking will not cause any harm to the eyes, not if you are under greater pressure for a long time, it will easily lead to various diseases, if you have the habit of smoking and drinking, it is best to quit or reduce smoking and drinking, so as to stay away from the damage of glaucoma.

3.Being in the habit of picky eating for a long time can easily lead to a lack of nutrients in the body, and glaucoma will come to the door, so maintaining good eating habits in life is the first step to help everyone stay away from diseases. You can actively adjust your eating habits and take in balanced nutrition.

4.Due to genetic glaucoma disease, if it cannot be carried out in time, it is easy to lead to glaucoma and there are many factors that induce glaucoma, so if you want to stay away from harm, you should start from the bits and pieces of life and actively prevent it, so as to help reduce the damage.

The causes of glaucoma are: 1. Anatomical factors: shallow anterior chamber, short eye axis, thick lens, and short corneal diameter, resulting in narrowing of the anterior chamber angle, impaired drainage of aqueous humor, increased intraocular pressure, and glaucoma formation.

2. Age and gender: open-angle type is more common around 30 years old, and there is no obvious gender difference. Angle-closure patients over 45 years of age account for glaucoma patients, and women are more likely than men.

3. Genetic factors: glaucoma is a polygenic hereditary lesion, and the incidence rate of those with family history is 6 times higher than that without family history, accounting for 13%-47% of the entire number of patients, and the incidence of relatives of patients is. 4. Refractive factor:

Patients with refractive error have a higher incidence of myopia, farsightedness, and presbyopia, and myopia is accompanied by or develops open-angle glaucoma, and hyperopia is mostly accompanied by closed-angle glaucoma. 5. Bad living habits: smoking and drinking, impermanence, irregular diet, moodiness, habitual constipation, intractable insomnia.

6. Systemic lesions of the eye. 7. Improper medication.

As the intraocular pressure rises beyond the eyeball's capacity, the structure of the eyeball is damaged, mainly the retina and optic nerve. Thus, increased intraocular pressure is an important manifestation of glaucoma, but not all glaucoma has elevated intraocular pressure. It is worth noting that some patients do not have high intraocular pressure, but glaucoma may occur because the eyeball has a relatively low tolerance for intraocular pressure.

People who are prone to glaucoma: it is more common in people over 40 years old; Those who are nearsighted; Diabetic; People with cardiovascular disease; Those who have a history of glaucoma in their immediate family.

1. Systemic diseases of the eyes. Glaucoma is an eye disease caused by systemic pathological changes after visceral lung dysfunction, which is not only caused by a variety of lesions, but also leads to further aggravation of other lesions, including local trauma, vitreous changes, retinopathy and other common causes.

2. Genetic factors. Glaucoma is a polygenic inherited disease and tends to be more common if there is a family history.

3. Refractive factors. If there is a refractive error, then the incidence of the patient's friend will be higher, and nearly 1:3 of the myopic patients will have open-angle glaucoma.

4. Age and gender. Open-angle glaucoma, which is often seen in people in their thirties, does not show a significant difference, while angle-closure glaucoma is more common in people over the age of 40 and is more common in women than men.

5. Bad living habits. If people often have a regular lifestyle, irregular diet, moodiness, and habitual constipation, then glaucoma may also be triggered.
