Is glaucoma scary and what is glaucoma?

Glaucoma is an eye disease in which the intraocular pressure is abnormally high and can lead to blindness in severe cases. Normal intraocular pressure is the result of a dynamic equilibrium between the amount of aqueous humor produced and discharged in the eyeball. Aqueous humor is the fluid that nourishes the cornea (dark eyeballs), but excessive production of aqueous humor or poor drainage of aqueous humor can increase intraocular pressure and lead to glaucoma.

At present, the medical treatment of intraocular pressure in glaucoma is basically to inhibit the production of aqueous humor, or increase the amount of aqueous humor from the anterior chamber angle (a tissue in the eyeball), that is, to increase the amount of aqueous humor from the anterior pathway, and ignore the discharge of aqueous humor from the grape sclera (another tissue in the eyeball), that is, from the posterior route. For those patients who have developed resistance to conventional drugs for a long time or who have been completely blocked by the anterior route due to disease, increasing the amount of aqueous humor from the posterior route has greatly increased the rate.

If it's acute glaucoma, you can also lose sight within a few hours. In chronic cases, the eyesight decreases a little bit every time you get sick, and it is best to have surgery as soon as possible. If your vision has deteriorated, it will not return.

Glaucoma is caused by a number of reasons that cause an increase in intraocular pressure, resulting in loss of optic nerve in the fundus. It is impossible to do so, and it can only be judged according to the time of intervention and the period of illness.

If there is already a loss of vision, these losses are irretrievable. Therefore, it cannot be said **, just to control the progression of the disease.

Analysis: Glaucoma is a serious eye disease caused by increased intraocular pressure, visual field defects, visual impairment, and even blindness, which is generally divided into four categories: primary, secondary, mixed and congenital glaucoma, with increased intraocular pressure as a common feature, and the clinical manifestations are mainly head and eye swelling pain, foggy vision, rainbow vision and vision loss. If you find suspicious symptoms, you should seek medical attention in time and strive for early diagnosis.

Patients should regulate their emotions, strengthen exercise, pay attention to eye hygiene, and avoid overeating.

This disease is equivalent to the category of "green wind internal cataract" and "green wind internal cataract" in traditional Chinese medicine. The disease is caused by insufficient endowment, loss of true yin, loss of seven emotions, fatigue and exhaustion, phlegm-dampness blockage, etc. Common clinical syndrome types are:

1. Liver stagnation and qi stagnation type: the head is swollen and painful, the vision is hazy, the black eyes are foggy like breath, the pupils are dilated, there is a rainbow halo when watching the lights, the intraocular pressure is increased, the systemic symptoms are uncomfortable, chest tightness and warmth, lack of food and sluggishness, vomiting and pan evil, bitter mouth, red tongue, yellow tongue coating, and the number of pulses.

2. Wet internal resistance type: sometimes eye swelling, rainbow vision, blurred vision, shallow anterior chamber, high intraocular pressure, headache, greasy tongue, and smooth pulse.

3. Phlegm and fire disturbance type: dizziness and pain, high intraocular pressure, upset and palpitations, less food and more phlegm, chest tightness and nausea, bitter mouth, red tongue, yellow greasy, and slippery pulse.

4 Heart and spleen deficiency type: It is seen that the eye syndrome is aggravated after fatigue in the spring chain, the head is dizzy and the eyes are swollen, the pupils are slightly dilated, the vision is dim, there is rainbow vision, insomnia, tinnitus, five heart irritability, dry mouth and throat, less tongue, and thin pulse.

5 Liver and kidney deficiency type: the vision is slowly decreasing, the field of vision is gradually narrowing, the pupils are dilated, the waist and knees are sore, the ears are ringing and the eyes are dry, the tongue is red, the moss is thin and white, and the pulse is thin.

6. Hyperactive liver yang type: Sudden redness and blur, corneal edema, dilated pupils, swelling and hard pain of the eyes, accompanied by headache and dizziness, red face, dry mouth, irritability, red tongue, yellow greasy, and stringy pulse.

1. Western medicine that can be used.

a) Primary glaucoma.

1 Angle-closure glaucoma:

1) Acute angle-closure glaucoma: mainly surgery, drugs can create better conditions for surgery, and intraocular pressure should be reduced as soon as possible.

Mydriatic medicine: 2 Pilocarpine eye drops once every 10-15 minutes, and once every 2 hours after the pupils are reduced and the intraocular pressure is reduced. The contralateral eye without seizures should also be treated with 1 to 2 pilocarpine, 4 times a day, to prevent seizures.

Hyperosmolar drug: 20 mannitol (1-2g per kg of body weight), 250-500ml, rapid intravenous infusion within 30 minutes.

Carbonic anhydrase inhibitors: acetazolamide is commonly used, 0 5 g orally for the first time, and 0 25 g each time thereafter, once every 6 to 8 hours. Taking baking soda tablets and potassium chloride at the same time can reduce***.

Other: indomethacin, adrenocorticosteroids can reduce inflammatory responses; Sedatives such as chlorpromazine can relieve nausea and vomiting.

vomiting and other symptoms. 2) Chronic angle-closure glaucoma: based on the principle of surgery**, the following drugs can be used**

1 Pilocarpine eye drops: 1 eye drop every 1-2 hours.

o,5 Timoramine eye drops: 1-2 times a day.

Glaucoma is an eye disease in which the pressure in the eyeball is abnormally elevated, exceeding the maximum limit that the eye can tolerate, causing optic nerve damage, visual field defects, and eventually vision loss and even blindness due to the increased pressure. Early prevention, recommend Aier Eye Hospital, click here, make an appointment in advance [**Appointment ophthalmologist number source] According to the age of onset, it can be infantile glaucoma and juvenile glaucoma, glaucoma under the age of 30 belong to this category, the cause of congenital glaucoma is that during embryonic development, the anterior chamber angle is abnormally developed, resulting in obstruction of aqueous humor discharge, causing an increase in intraocular pressure, 25-80% of patients show it within half a year, 90% of children can be diagnosed by the age of one, 10% of patients develop symptoms between 1 and 6 years of age. To consult more information about glaucoma, it is necessary to choose a strong Aier ophthalmologist....

Most of the water in our eyeballs is a substance like water, the first half of the aqueous humor is called aqueous humor, aqueous humor is like blood is constantly circulating, there are new aqueous humor constantly generated, and the original aqueous humor has to circulate to the outside of the eyeball through a place called trabecular meshwork, so as to maintain normal eye pressure. When the circulation of aqueous humor is blocked due to various reasons, the pressure in the eyes increases. This pressure is transmitted to the retina, which will compress the retina and optic nerve, thereby damaging our visual function.

Therefore, glaucoma must be treated in a timely and orderly manner!

Glaucoma is a severe, irreversible blinding eye disease. The main reason is that the ocular (internal) pressure exceeds the tolerance limit of the optic nerve in the fundus, which causes the optic nerve to gradually atrophy, the visual field to gradually shrink and even complete blindness.

Glaucoma is a complex type of disease that refers to pathological intraocular hypertension, visual field defects and damage to the optic nerve in the fundus. It can be divided into angle-closure glaucoma, open-angle glaucoma and some special types of secondary glaucoma.

Different types of glaucoma have different symptoms, but in the case of acute angle-closure glaucoma, it can lead to short-term vision loss, and the symptoms are very severe. The main manifestations are headache, eye pain, nausea and vomiting.

There is also some potentially dangerous glaucoma, which does not have any uncomfortable symptoms in itself, but the vision gradually decreases. Generally, chronic angle-closure glaucoma or open-angle glaucoma has this possibility.

Glaucoma is a group of groups that threaten and damage the optic nerve and its visual pathways, ultimately leading to visual impairment, mainly related to pathological intraocular hypertension. Glaucoma is divided into primary, secondary, congenital and other glaucoma according to science, anatomy, pathogenesis, etc., and intraocular pressure lowering eye drops, lasers, surgery, etc. are generally used. If not effective**, the visual field can be completely lost, and eventually blindness.

Glaucoma is an eye disease, the elderly are the majority, you should see a doctor as soon as possible if you have this disease, and you can effectively get **, otherwise the consequences will be very serious and will cause blindness.

Eye disease caused by increased pressure in the eye, symptoms are dilated pupils, corneal edema, grayish-green color, severe headache, vomiting, and rapid loss of vision. Also called green cataract.

Pathological intraocular pressure increases, resulting in damage to the optic nerve, resulting in vision loss, visual field defects blinding eye disease.

What is glaucoma? Glaucoma is a problem with the fundus of the eye, and then it is no longer visible, it is called glaucoma.

Not everybody will have glaucoma, it depends on the specific condition of the eye, and some diseases are not easy to predict.

Glaucoma is an eye disease that can cause blindness, and its main mechanism is that the structure of the eye is damaged due to the increase in intraocular pressure that exceeds the capacity of the eyeball. Damage mainly refers to the retina and optic nerve. Therefore, our increased intraocular pressure is a manifestation of glaucoma, but not all glaucoma will have an elevated intraocular pressure.

It is worth noting that some patients do not have high intraocular pressure, but they may also develop glaucoma because of their low tolerance for intraocular pressure. There are two main mechanisms of glaucoma, one is open-angle glaucoma and the other is closed-angle glaucoma. Open-angle glaucoma occurs when intraocular pressure is impaired by the aqueous humor outflow function of the corner.

Angle-closure glaucoma, which is the location of aqueous humor outflow due to mechanical obstruction, will cause an acute increase in intraocular pressure, resulting in typical symptoms of an acute attack of glaucoma, including eye pain, headache, and even nausea, vomiting, and vision loss. Therefore, in general, glaucoma is related to intraocular pressure, and the direct consequence of it is the impairment of visual function, which is mainly manifested as a defect in the visual field. What is visual field defect?

It's that our range of vision will become smaller and smaller, not that our central vision will be affected. Some advanced glaucoma centers can still see achievable, even, but because the scope of his vision is so small that he is not able to live independently, he loses the ability to live on his own. Therefore, we must know that the main result of glaucoma is visual field defects, which can cause damage to visual function and cause inability to take care of oneself.

1.Glaucoma can be blinding and irreversible.

Glaucoma is defined as a group of eye diseases that threaten and impair the visual function of the optic nerve and are primarily associated with an abnormal increase in intraocular pressure. In other words, if the intraocular pressure exceeds the optic nerve in the eye tissue, especially the retina, it can damage the visual function of the eye tissue, especially the optic nerve. If you don't take effective ** in time, your vision may be lost and you may end up blind.

Current medical technology is not able to reverse and restore this blindness caused by glaucoma.

2.Glaucoma without "glaucoma" in the early days.

There are two most common types of glaucoma, one is acute congestive glaucoma, also known as primary angle-closure glaucoma, which is characterized by redness of the eyes, dilated pupils, and corneal edema due to refraction. It also emits a green light, which is the name of glaucoma. Patients also suffer from headaches, nausea and vomiting.

However, there is another common type of glaucoma, chronic simple glaucoma, also known as primary open-angle glaucoma, which has a subtle incidence and slow progression, with no symptoms in the early stages, let alone reflecting "glare".

3.Chronic simple glaucoma that does not emit "glaucoma" is more harmful.

The eyeball is an important organ for metabolic activity. There is a certain amount of living water, i.e., aqueous humor, in the eyeball to provide some nutrients to the structure of the eye and to maintain moderate pressure in the eye, i.e., intraocular pressure. This is because the water in the room is constantly circulating, and the eyes are energized.

Acute congestive glaucoma is the closure of the angle of the room, i.e., the failure of the drainage system, resulting in an "overflow" of aqueous humor and intraocular pressure. Despite the intense, even the "glare" glittering, the "open corners" of the surgery eliminate the malfunction that could cause the water in the room to circulate again. This type of glaucoma** is therefore effective.

However, chronic simple glaucoma is usually asymptomatic in the early stages. By the time the disease progresses to the middle and late stages, it is already very difficult and vision is greatly reduced, which actually makes the doctor unprepared. It can be seen that chronic simple glaucoma without "glare" is more harmful.

Glaucoma is one of the most common blinding diseases and is characterized by increased intraocular pressure, optic nerve atrophy, and visual field defects. In most cases, the cause of optic nerve damage is mainly high intraocular pressure, but in a few patients it occurs at normal intraocular pressure, which is called normal intraocular pressure glaucoma. Although the clinical features of glaucoma are diverse, the most important harm is visual impairment, which manifests as decreased visual acuity and visual field defects.

Vision loss generally occurs during acute intraocular hypertension, and the initial stage of visual acuity loss is due to the high intraocular pressure that the corneal endothelium cannot properly drain the water in the cornea, resulting in corneal epithelial edema; Acute persistent intraocular pressure can reduce visual acuity to light perception because high intraocular pressure severely affects the metabolism of optic cells. Chronic intraocular hypertension and the later stages of persistent intraocular hypertension cause optic nerve atrophy, resulting in visual field defects.

Glaucomatous optic nerve atrophy is multifactorial, but the most common causes are mechanical compression and optic disc ischemia. High intraocular compression causes the scleral cribriform plate to bulge backwards, and the optic nerve fibers through the cribriform plate are squeezed and stretched, blocking the axial plasmic flow of optic nerve fibers, and high intraocular pressure may cause optic disc ischemia, aggravate the damage of optic nerve fibers, and eventually lead to optic nerve atrophy.

Because the occurrence of visual field defects is insidious and gradual, especially in primary open-angle glaucoma, it is not easy to detect because the early clinical manifestations are not obvious or have no specificity, and once the vision loss is found, it is often in the late stage of the disease, and the visual field defect is serious and irreversible. Therefore, glaucoma emphasizes early detection and timely detection.
