What causes glaucoma syndrome?

It does not matter. This is a special constitution.

Glaucoma is a common and difficult eye disease that has a rapid onset, is harmful, and can lead to blindness at any time. It is characterized by intermittent or persistent elevation of intraocular pressure beyond the tolerance of the eyeball and damage to the tissues and visual function of various parts of the eyeball, resulting in optic nerve atrophy, visual field narrowing, vision loss, blindness is only a matter of time, and complete blindness can be achieved in 24-48 hours during the acute attack. Glaucoma is a binocular lesion that can occur in both eyes at the same time, or onset in one eye, secondary to blindness in both eyes.

You can try the white and green combination, the effect is not bad.

You can use the white-green combination, this product works very well, mainly for cataracts and glaucoma.

Glaucoma is a disease of optic disc damage and visual field defects caused by pathological intraocular pressure increases, and the causes vary depending on the type of glaucoma. Among them, primary angle-closure glaucoma is related to the anatomy of the anterior segment of the patient's eyes, and patients with shallow anterior chamber and narrow angle are prone to glaucoma, which is common in women over 40 years old.

The cause of primary open-angle glaucoma is not well understood, but it is thought to be related to trabecular meshwork dysfunction. Developmental glaucoma is associated with dysplasia of the anterior chamber angle, and secondary glaucoma is associated with other eye diseases and systemic diseases, such as common diabetes. In short, there are different types of glaucoma and various causes of the disease, in this case, it is necessary to go to a regular hospital and make a correct diagnosis according to the doctor's opinion.

Different types of glaucoma are caused by different causes, as follows:

1. Primary glaucoma: including angle-closure glaucoma and open-angle glaucoma, the water in the eyeball cannot flow out of the eyeball smoothly and cannot enter the blood circulation system, which will cause increased intraocular pressure and optic nerve damage in the fundus, forming glaucoma. If the shallow anterior chamber and narrow angle of the atrial angle, there are a large number of glycoproteins in the trabecular mesh in the angle of some patients, such as the factor of opening angle, which will cause glaucoma;

2. Secondary glaucoma: glaucoma caused by trauma or inflammation, such as iris cyclitis, vascular glaucoma, etc., and glaucoma secondary to other diseases is called secondary glaucoma;

3. Congenital glaucoma: caused by abnormal development of angle structure during the embryonic period, including infantile and juvenile glaucoma.

Different causes and symptoms of glaucoma also determine different treatment methods, and the main options for glaucoma include drugs and surgery.

Pathologic intraocular hypertension is a major risk factor for glaucoma. Elevated intraocular pressure leads to optic nerve damage through two mechanisms: mechanical compression and causing optic nerve ischemia. The longer the increase in intraocular pressure persists, the more severe the visual impairment.

The increase in intraocular pressure in glaucoma is caused by a disruption of the homeostasis of the aqueous humor circulation. A small number of aqueous humor secretions are due to excessive secretion, but most of them are still obstructed by aqueous humor outflow, such as narrowing or even closure of the anterior chamber angle, trabecular sclerosis, etc.

Elevated intraocular pressure is not the only risk factor for the onset of glaucoma, some patients have normal intraocular pressure but have typical glaucoma pathological changes, and some glaucoma patients have controlled intraocular pressure, but the optic nerve damage is still progressively developed, indicating that there are other factors related to the onset of glaucoma, such as local anatomical variations of the eyeball, age, ethnicity, family history, myopia, cardiovascular disease, diabetes, hemrheological abnormalities, etc.

Top three. Pigmented glaucoma is a type of glaucoma caused by chronic loss of pigment in the pigment epithelial cell layer of the membrane, which is deposited in the retrocornea, the surface of the lens and suspensory ligament, and the trabecular reticulum file, which obstructs the drainage of aqueous humor. It can cause increased intraocular pressure, visual field defects, and optic nerve changes.

This disease is mainly caused by the posterior iris fovea, which causes friction between the posterior iris pigment epithelial cell layer and the superficial surface of the crystal and the suspensory ligament, resulting in chronic loss and deposition of pigment. Common in patients with moderate to high myopia. Some patients may also have a chromosomal abnormality.

Glaucoma is a complex group of "hidden" eye diseases, usually caused by increased intraocular pressure, optic nerve damage, and visual field defects. Prolonged intraocular hypertension can damage some or all of the optic nerve, reducing the quality and quantity of information sent by the optic nerve to the brain, and the patient's vision will gradually deteriorate or become blind. The damage to peripheral vision and central vision in glaucoma is progressive, and most glaucoma patients cannot be completely affected.

However, if it can be detected early, diagnosed early, and scientifically and reasonably carried out under the guidance of a doctor, the blindness rate of glaucoma can be completely reduced.

Regular glaucoma screening is the best way to detect it early, so experts recommend glaucoma screening as a routine eye exam. Most people should have a comprehensive glaucoma exam around the age of 35, another at age 40, every 2-3 years after age 40, and every 1-2 years after age 60. Due to the complex classification of glaucoma, there are many types of tests that need to be performed for its diagnosis.

The most basic tests include: intraocular pressure and daily intraocular pressure curves and the dark recumbent test; Optic nerve examination: ophthalmoscopy and stereoscopic fundus photography; Anterior chamber angle examination:

gonioscopy and anterior chamber morphometry; Visual field examination: At present, microcomputer automatic visual field examination is the main one.

Primary glaucoma is divided into angle-closure glaucoma and open-angle glaucoma according to the state of the anterior chamber angle when the intraocular pressure increases, and the angle-closure glaucoma is divided into acute angle-closure glaucoma and chronic angle-closure glaucoma according to the severity of the onset.

1.Acute angle-closure glaucoma.

The occurrence of acute angle-closure glaucoma is caused by the sudden narrowing or closure of the atrial angle in the eye, and the aqueous humor cannot be discharged in time, causing the aqueous humor to be full and the intraocular pressure to rise sharply. It is more common in middle-aged and elderly people, 90% of them are over 40 years old, and the incidence rate of women is higher, the ratio of men to women is 1:4, the onset is violent, the symptoms are acute, and there may be transient or repeated small seizures before the acute onset, which is manifested as sudden foggy vision and rainbow vision, accompanied by forehead pain or soreness at the base of the nose.

At the onset of the disease, the anterior chamber is stenosis or completely closed, and the symptoms are sudden onset of severe eye swelling, eye pain, photophobia, tearing, headache, sharp loss of vision, hard as stones, conjunctival hyperemia, accompanied by nausea and vomiting and other systemic symptoms. An acute attack can be followed by a chronic phase of persistent optic nerve damage until the optic nerve is severely damaged and vision is reduced to an absolute phase of lossless and irreversible.

2.Chronic angle-closure glaucoma.

The age of onset is over 30 years old. This type of attack generally has obvious triggers, such as emotional agitation, visual fatigue, excessive use of eyes and brain, long-term insomnia, habitual constipation, women during menstruation, or improper local and systemic medication, etc., can be induced, manifested as dry eyes, fatigue and discomfort, swelling pain, blurred vision or decreased vision, rainbow vision, dizziness, insomnia, increased blood pressure, and can be relieved after rest. Some patients can be blind without any symptoms, and the intraocular pressure may be normal or fluctuating during examination, or not too high, 20 30 mmHg, and the fundus may be normal in the early stage, which is most likely to be misdiagnosed.

In this way, once the anterior chamber angle is adhered to and closed, fulminant glaucoma can be formed.

There are four early symptoms: Frequent eye strain and discomfort. Eyes are often sore, which is relieved by rest. Blurred vision, myopia, or sudden deepening of presbyopia. Eyes often feel dry.

3.Primary open-angle glaucoma.

It mostly occurs in people over 40 years old, 25% of patients have a family history, the vast majority of patients have no obvious symptoms, often the disease develops to an advanced stage, and the visual function is severely impaired before it is noticed, although the patient's intraocular pressure is elevated, the anterior chamber angle is always open.

Glaucoma is divided into primary glaucoma and secondary glaucoma, primary glaucoma is a polygenic genetic disease, it has a family history than no family history is 6 times higher, but also affects the factors of glaucoma, generally there are no symptoms, some often do not know that their eyes have a problem with the case of glaucoma, for example, acute angle-closure glaucoma attack will suddenly appear eye pain, headache, accompanied by nausea, vomiting.

Of course, bad habits, such as smoking, alcoholism, impermanence, irregular life, irregular diet, etc., as well as improper medication, such as the use of hormones, can also cause glaucoma.

Because glaucoma is a group of difficult diseases, it includes primary, secondary, drug-induced, etc., and even congenital. In summary, there are two main reasons, one is that the drainage channel of the aqueous humor in the eye is blocked, just like the sewer at home is blocked, the water will gush out, and the drainage channel of the aqueous humor in the eye is blocked, and the intraocular pressure will rise, which is a type. There is also a type, that is, the faucet is too large, that is, the ciliary body epithelial cells have too much aqueous humor in the deep layer, this type is relatively less, whether the aqueous humor in the eye is blocked or too much, it can cause our intraocular pressure to rise, beyond the scope of our nerve damage, causing visual field damage, which can cause glaucoma.

So the causes of it are nothing more than these two categories.

1. Bad lifestyle habits are also one of the glaucoma**.

Smoking, alcoholism, daily routine, irregular diet, moodiness, habitual constipation, intractable insomnia.

2. Glaucoma** is related to anatomical factors.

The anterior chamber is shallow, the axial eye is short, the lens is thick, and the corneal diameter is short, resulting in narrowing of the anterior chamber angle, impaired drainage of aqueous humor, increased intraocular pressure, and glaucoma formation.

3. Refractive factor.

Patients with refractive errors (myopia, farsightedness, presbyopia) have a higher incidence, myopia is accompanied by or develops open-angle glaucoma, and hyperopia is mostly accompanied by angle-closure glaucoma.

4. Age and gender.

Open-angle type is more common around the age of 30, 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. This is also one of the glaucoma**.

5. Genetic factors.

Glaucoma is a polygenic hereditary lesion, and the incidence rate of patients 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 of relatives of patients is .

In fact, glaucoma is usually caused by pathological high intraocular pressure, but it is a common ophthalmic disease. The general pathogenesis is mainly aqueous humor circulation disorder, which leads to a sharp increase in intraocular pressure and causes headache.

There are many causes of glaucoma, such as the weather season, or it can also be caused by unhygienic eye use. Because glaucoma is a group of diseases characterized by optic nerve atrophy and visual field defects. In terms of **, it is best to use drugs first**, you can use a low-concentration liquid first, and then use a high-concentration liquid to drop your eyes, and if the effect is not good, surgery can be considered**.

These drugs may produce a corresponding *** at the same time as the ** effect.

Traditional Chinese medicine believes that glaucoma is caused by wind and fire. Phlegm. Yu and yin and yang imbalance, causing qi and blood disharmony, unfavorable meridians, occlusion of the Xuanfu in the eyes, and the failure of the qi, blood and fluid in the beads The general symptoms are violent, in addition to eliminating the ** and treating its roots, we should also pay attention to shrinking the pupils, opening the Xuanfu, eliminating stasis, and improving the symptoms to protect the eyesight

Hello, factors such as overwork, lack of sleep, mood swings, uncontrolled diet or overeating can affect the vascular neuromodulation center and make the vasomotor dysfunction: on the one hand, it can dilate the capillaries and increase the permeability of the blood vessels, causing ciliary muscle edema, moving forward, blocking the anterior chamber angle, and blocking the flow of aqueous humor out of the channel; On the other hand, it can cause excessive secretion of aqueous humor, too high pressure in the posterior chamber, and the pressure of the peripheral iris moves forward to make the anterior chamber shallow and the anterior chamber angle narrow. All of these factors can cause a sharp increase in intraocular pressure, which can eventually lead to an acute attack of glaucoma.

1. Family history of glaucoma: If there is a family history of glaucoma, then every other member should have a comprehensive examination on a regular basis, and if necessary, long-term regular observation, especially family members over 60 years old should be carefully examined.

2. Systemic diseases: such as diabetes, hypertension, hypotension, etc., which will cause the occurrence of glaucoma. If glaucoma has been diagnosed in one eye, the other eye should be examined as soon as possible.

3. Eye diseases related to glaucoma: such as high myopia, high farsightedness and fundus hemorrhage, etc., which may induce the occurrence of glaucoma. Therefore, these groups of people should strengthen their eye care in their daily life.

4. Ignoring eye symptoms: What causes glaucoma? In some patients, the symptoms are not obvious, not easy to detect, and can be easily ignored until the visual function is severely impaired, which is delayed**.

Early detection and early ** to avoid the development of optic nerve atrophy in the later stage will be troublesome.

Further detailed examination and follow-up are required to observe if there is any change in the condition, and if two of the three indicators of visual field, fundus and intraocular pressure are abnormal, then the diagnosis of glaucoma can be confirmed.
