Do you know what the three major harms of glaucoma are? What are the symptoms of glaucoma?

These hazards can cause serious damage to one's body, and can cause damage to the optic nerve, which may also lead to cataracts and other diseases. Typical symptoms are soreness and pain, nausea, vomiting, and headaches.

Glaucoma causes the optic nerve to gradually shrink and the visual field to shrink. Soreness and pain in the eyes, headache, nausea, vomiting, rainbow vision, etc.

Leads to decreased visual acuity, increased intraocular pressure, damage to optic nerve function; His main symptoms were decreased vision, headache, vomiting.

1. Significant loss of vision

The patient's vision will slowly deteriorate, and the vision cannot be achieved even with glasses. Especially for people with severe myopia, wearing more suitable glasses can also cause dizziness.

2. Swollen eyes and headache

When the patient is emotionally agitated, or stays in a dark place for too long, he will have swollen eyes, headache, blurred vision, etc., as if there are clouds in front of his eyes, and this symptom is generally closed-angle glaucoma. After many recurrences, it is possible to suddenly enter the acute major attack phase.

3. Rainbow vision

When you look at the lights at night, colorful circles of light appear in your eyes, just like a rainbow that appears in the sky after a rain, which is called rainbow vision in medicine. This is a very special symptom of glaucoma and should be taken seriously.

4. Difficulty reading in the morning

When I wake up in the morning, I feel that my eyes are very uncomfortable when I read, and my eyes and forehead will be swollen and painful. This is because the intraocular pressure of glaucoma patients fluctuates greatly for 24 hours, so the intraocular pressure is higher in the morning, and symptoms appear.

5. Increased intraocular pressure

Once you have glaucoma, it will cause the intraocular pressure to rise, and then the condition will worsen, which will endanger the patient's health. Therefore, intraocular pressure should be properly controlled. In general, the normal intraocular pressure range is 10-21 mm Hg, and when the intraocular pressure rises to 25-40 mm Hg, the finger touch of the eyeball is like a full ball, which is relatively hard.

When it rises to 40-70 mmHg, the eyeballs are as hard as stones when you touch them with your fingers.

The symptoms of glaucoma are not very obvious, and it is easy to ignore the past, **Glaucoma has to go to a professional eye hospital, Qingdao New Vision Eye Hospital is very good, you can go to see it.

At this time, it is what we usually call water eyes, and in this case, it is necessary to take the patient to the hospital as soon as possible.

Therefore, if the patient has cataracts, we should avoid long-term ultraviolet sun exposure in our daily life and when we go out.

Hello, under normal circumstances, the five major symptoms of glaucoma are as follows: first, increased intraocular pressure, second, narrowing of the visual field, third, headache and eye swelling, fourth, nausea and vomiting, fifth, rainbow vision, in short, glaucoma patients in addition to the necessary **, in the diet is also able to prevent and control the disease, on weekdays patients can eat more foods containing vitamins, fresh vegetables and fruits, such as daylily, bergamot, longan, red dates, wolfberry, peanuts, walnuts, soy milk, poria, beef, malt, Vegetable oil, soybeans, peanuts, egg yolks, etc.

Glaucoma is a blinding eye disease, because there are no obvious symptoms in the early stage, and once the onset of the disease is irreversible damage to visual function, it will often be ignored by patients, and is also known as "thief who steals vision"!

Most glaucoma has no symptoms in the early or even middle stages, especially when one eye develops first, and it is not detected until the binocular vision function is severely impaired. Routine physical examinations do not necessarily detect early glaucoma.

Half of glaucoma patients in developed countries do not know they have glaucoma, while more than 90% of glaucoma patients in developing countries have no knowledge of their disease or have never even heard of glaucoma. Glaucoma can occur at any age and is more common in older people, and its prevalence increases with age.

Early symptoms of glaucoma.

1. If you are emotional or stay in the dark for too long (such as watching movies, TV or working in a dark room), you will have eye swelling, headache, blurred vision, and a layer of clouds in front of your eyes, which is an early symptom of angle-closure glaucoma. After repeated recurrences, it is possible to suddenly enter the stage of acute glaucoma grand attack.

2. After getting up in the morning, it is difficult to read books and newspapers, and it is easy to have soreness at the base of the nose bridge and swelling and pain in the orbit and forehead. Because the intraocular pressure of normal people fluctuates day and night, it is generally higher in the morning and lower at night. In patients with glaucoma, the intraocular pressure fluctuates more in 24 hours, so the intraocular pressure is higher in the morning, and symptoms appear.

3. The visual acuity gradually declines, and the visual acuity correction of optometry glasses is not logarithmic on the eye chart, especially for people with high myopia, who often have headaches and eye swelling after wearing moderate glasses. Due to the elongation of the sclera (the white part of the eye) in high myopia, there is a noticeable decrease in elasticity. Therefore, when there is high intraocular pressure, the symptoms are not obvious or asymptomatic, the patient is easy to be negligent, but the vision is quietly lost, and the doctor is often easy to miss the diagnosis.

4. Usually drink a lot of water, and headache occurs when drinking more than 300 ml of water at a time. This is because drinking water quickly and in large quantities can cause blood dilution to cause a decrease in osmotic pressure, and the amount of aqueous humor entering the eye will increase, resulting in an increase in intraocular pressure. Patients often present with eye swelling headache 15 to 30 minutes after drinking water.

Presbyopia develops before the age of age (which should be distinguished from earlier onset of presbyopia in hyperopia), especially in women, and the presbyopia changes rapidly, requiring frequent changes in glasses. This may be related to decreased ocular accommodative ability and is directly proportional to the degree of early glaucoma lesions.

1.Acute angle-closure glaucoma: symptoms are acute, manifested by sudden hazyvision and iridescence, with frontal 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: onset age 30 years of age.

This type of seizure usually has obvious triggers, such as eye dryness, fatigue and discomfort, swelling pain, blurred vision or decreased vision, iridescence, dizziness, insomnia, and increased blood pressure, which can be relieved by rest. Some patients can go blind without any symptoms, and this type is most likely to be misdiagnosed. On the contrary, once the anterior chamber angle is adhesion closed, fulminant glaucoma can be formed.

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 increased, the anterior chamber angle is always open.

First of all, bad lifestyle habits are one of them, smoking, alcoholism, daily life, irregular diet, habitual constipation, intractable insomnia, etc., may cause the onset of glaucoma.

1.Drugs**.

In conclusion, glaucoma is a common eye disease that can lead to blindness. The best way to prevent glaucoma is to have regular eye check-ups and maintain a healthy lifestyle. If you have any questions or symptoms, seek medical attention promptly.

2.Surgery**.

Glaucoma is a common eye disease and one of the important causes of blindness. Glaucoma is a group of diseases caused by increased intraocular pressure, often asymptomatic, which eventually leads to damage to the optic nerve and blindness of the eyeball.

Medications** are used to control glaucoma primarily by lowering intraocular pressure. Commonly used drugs include receptor blockers, BCG, prostaglandins, etc.

Glaucoma is a disease in which the optic nerve and visual field are damaged due to increased intraocular pressure. There is a part of the water-based ingredient in the eyeball, which is waterproof, and plays a very important role in maintaining and regulating the pressure in the eye.

Glaucoma is a general term for a large group of diseases, mainly due to increased intraocular pressure pressing on the optic nerve, resulting in atrophy of the optic nerve and visual field defects. Most of this condition is caused by congenital dysplasia and obstruction of the aqueous humor drainage channel inside the eye, resulting in increased intraocular pressure of aqueous humor and stasis.

However, there are some individual conditions that have a cause, such as after trauma, which can cause the angle to recede, resulting in secondary glaucoma, and long-term use of hormonal drugs may cause hormonal glaucoma, which are called secondary glaucoma, and there is a clear reason. For primary glaucoma, which is the most common type of glaucoma, which is mainly divided into primary angle-closure glaucoma and primary open-angle glaucoma, there is no specific cause and is related to congenital developmental abnormalities.

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.

Glaucoma is a very serious eye condition that can lead to blindness. Glaucoma is classified into several types, such as primary, congenital, and secondary. The occurrence of glaucoma in general is also related to bad lifestyle habits.

For example, smoking, alcoholism, and daily life are all likely to lead to the occurrence of glaucoma.

The main cause of glaucoma is older age, and most older people will get glaucoma.

Glaucoma is generally due to high intraocular pressure and optic nerve compression and functional damage, which causes vision loss, blurred vision, headache, eye pain, and rainbow vision around the light, so it must be detected and prevented early.

There are many causes of glaucoma, which are as follows:

1. Anatomical factors: especially primary angle-closure glaucoma, which has the characteristics of short eye axis, shallow anterior chamber, thick lens, and small corneal diameter, resulting in narrow anterior chamber angle, obstruction of aqueous humor outflow, and increased intraocular pressure;

2. Age and gender: open-angle glaucoma mostly occurs in young people over 18 years old or young and middle-aged people, and the incidence of patients with high myopia increases, and there is no obvious gender difference at present. More than 68% of patients with angle-closure glaucoma are over 45 years old, and there are more women than men.

3. Systemic diseases: especially diabetes mellitus can cause diabetic retinopathy, which can then lead to neovascular glaucoma;

4. Drugs: common hormonal glaucoma;

5. Genetic factors: most glaucoma patients have a hereditary family history.
