What are the factors that make a person often blind and what are the causes of blindness

If you find that you are suddenly blind in your eyes, you should go to a professional eye examination in time

There are many eye diseases that can cause blindness, especially some eye diseases that are so violent that they can be blinded in an instant. The following diseases can easily cause sudden blindness in the eyes. (1) Retinal artery blockage, and sudden occurrence of ** total blindness in one eye at the time of illness.

The main causes are arteriosclerosis, high blood pressure and heart disease. (2) Fundus or vitreous hemorrhage, when you are sick, you suddenly feel black and smoky in front of your eyes, and sometimes you can see black or red objects floating in front of your eyes. The causes of the disease are mostly hypertension, arteriosclerosis, diabetes, etc.

After medication and surgery**, the condition can be effectively controlled. (3) Acute optic neuritis, visual acuity decreases sharply, often accompanied by pain when the eyes move, and once optic neuritis occurs, blindness will occur suddenly. Some lesions in the human body, such as paranasal sinusitis, tonsillitis, gingivitis, otitis media, epidemics, pneumonia, diabetes, beriberi, etc., may cause the occurrence of acute optic neuritis.

If you can go to the hospital in time** acute optic neuritis, your vision can be restored. (4) Ischemic optic neuropathy with sudden loss of vision, no pain during eye movement. Fundus optic disc vascular lesions, increased blood viscosity, hypotension, and increased intraocular pressure can all cause the condition.

For systemic diseases**, glucocorticoids, vasodilators, and intraocular pressure are reduced**. (5) Acute attack of angle-closure glaucoma is manifested as severe headache, eye pain, photophobia, tearing, and severe vision loss to blindness. Local anatomical variations in the eye are the main factors in the pathogenesis.

Regular eye examinations can help to detect the disease early, and if diagnosed early, drugs, lasers or surgeries may be more effective. People over 40 years old, especially patients with diabetes, hypertension and hyperlipidemia, no matter what the circumstances, find that the eyes are suddenly blind, and they should go to a professional eye examination in time.

There is no doubt that blindness, the unknown and fear caused by the loss of eyes is much greater than that of deafness, and the amount of information that the brain can obtain will be much less.

Blindness and deafness both have an impact on daily life, blindness is invisible, deafness is inability to hear, blindness can be on crutches, beating and walking, deafness can't hear, it is necessary to learn sign language to communicate, relatively speaking, deafness has a slightly smaller impact on personal life.

Blindness and deafness are detrimental to people's lives. But blindness affects people's lives even more. Because of blindness, everything in the outside world cannot be seen, which has a great influence on people's actions. Deafness does not affect a person's walking, at least. Therefore, blindness affects a person's life more than deafness.

In terms of the current level of science and technology, blindness has the greatest impact on people, because many of the current exchanges can be completed using modern technology, so deafness is not terrible, but if you are blind, there are many kinds of modern equipment that cannot be used, and you will lose most of your jobs, and if your family is not rich, you can only live a life in poverty.

Blindness and deafness have a great impact on people's lives, but blindness is too terrible, there is darkness in front of you, you can't see anything, you can't take care of yourself in life, it's too scary, deafness just can't hear, and it doesn't have a big impact on life.

Of course, blindness has a greater impact on an individual's life, because the eyes are the window to the human soul and have great significance.

It should be that blindness has a greater impact on people's lives, they can't see with their eyes, and they need to be taken care of by others in their lives. And deafness is just not able to hear sounds, almost no big impact on daily life, and can even go to work, but can blind people go to work?

I think the impact of deafness is even greater, because after being deaf, you can't hear others and yourself, and after a long time, you lose the ability to speak.

I think that blindness, although deafness, there will be a great obstacle, but blindness will hinder even more!

For normal people, no matter what the cause of personal injury, the harm to the victim's life is unacceptable.

Or is blindness more impactful, and if you can't see, you can't do anything. Either way, health is the best

Of course, deafness has the greatest impact on people's lives, and if people don't have brains, they are wasted.

Blindness has a greater impact on life than deafness, and blindness has a shorter lifespan than deaf people".

Blindness. Because the deaf can at least use sign language, almost everything that is blind is taken care of by others.

Of course, blindness, the harm of not being able to see with the eyes is far greater than the consequences of not being able to hear with the ears.

Blindness has the greatest impact because 90% of a person's information is obtained through the eyes.

Citizens have a greater impact on people's lives, and deafness also has a certain impact.

Blindness is even greater. If you are deaf, you can't hear others, so you will be much quieter.

Blindness has the greatest impact.

The most information is received through the eyes.

Which one has a greater impact on life? It should be that the real name is more serious.

The impact is great, but blindness should have a bigger impact.

Blind, I feel cut off from the whole world.

He must be blind, and he will never see the light.

Blindness has a little more impact on life.

Blindness is the most affected.

It is mostly caused by internal cataract diseases and other eye diseases, and can also be caused by brain lesions. Qi and blood stasis, phlegm and heat are common pathogenesis, liver fire is excessive, and liver and kidney yin and blood deficiency are common.

1. Arteriosclerosis. Sudden blindness of the eye can be caused by hardening of the arteries or heart disease, and the patient can go blind in minutes or even seconds without warning. Arteriosclerosis is a very common vascular disease that is related to genetic factors, aging, lifestyle habits, etc.

Arteriosclerosis usually develops after emotional agitation and strenuous activity, and the disease progresses rapidly.

2. Fundus hemorrhage. Fundus hemorrhage and vitreous hemorrhage can also cause sudden blindness, which is more common in patients with diseases such as diabetes, high blood pressure and arteriosclerosis. Fundus hemorrhage can occur anywhere in the fundus, and if it is centered, the patient becomes blind.

3. Acute neuritis. Acute neuritis is a common ophthalmic nerve disease, and the patient will suddenly lose sight during the acute attack, and the patient's vision can return to normal after receiving **. Acute neuritis begins quickly, and the patient's vision deteriorates suddenly, and after a few days it drops to no light.

The patient has significant traction-like pain when the eye is rolled, and the orbit is markedly tender.

There are many factors and causes of insomnia, and different types of insomnia have different causes. Generally speaking, the most common and intolerable symptoms of insomnia are difficulty falling asleep, early awakening, and intermittent multiple awakenings during sleep, which are the most common symptoms of insomnia that bothers patients.

1 Excessive stress can lead to insomnia.

Mental stress is common**. Many people with chronic insomnia are considered to be overly nervous and complaining. They are overly sensitive to the slightest discomfort in their surroundings and do not relax easily.

Or overthinking, or over-excited, agitated due to intense psychological conflicts.

Abuse of sleeping pills or stimulants.

Unhealthy lifestyles, such as irregular daily life, high-intensity mental work, and too little physical activity, among which people who sit in the office for a long time are most likely to suffer from insomnia.

Dietary factors, overeating or starving at bed, drinking coffee, strong tea or other stimulant beverages before bedtime.

Sleep environment factors, such as bright light, noise, or a bedroom with too high or too low a temperature, or an insecure sleeping environment, can lead to insomnia.

Having an incorrect attitude towards sleep, such as thinking that you have to get more than 8 hours of sleep every night, and when you don't get enough sleep, you worry about not getting enough sleep, which can also lead to insomnia.

2 Other causes of insomnia.

Improper living arrangements, emotional excitement before bedtime, and having something on your mind will inevitably affect your sleep, leading to insomnia or dreams.

The elderly are already weak in kidney qi, such as drinking water before going to bed, eating watermelon, drinking gruel and other foods with more water, urine will increase at night, and it will be naturally difficult to fall asleep.

It is already difficult for insomniacs to fall asleep, if the bed is not suitable, the surrounding environment is poor, the ventilation is poor, the light surface is too bright or the surrounding noise will aggravate insomnia.

It is worth mentioning that, in general, milk contains calcium and tryptophan, which are good for sleep, but there are also some people who can't fall asleep after drinking milk, especially some infants and young children due to imperfect physical functions, there will be "milk insomnia" after drinking milk, please pay attention to it.

Severe short-term insomnia can lead to chronic insomnia and the possibility of a variety of diseases. If there are some conditions, you should see a doctor in time:

Obvious insomnia symptoms persist for more than a month with no clear cause.

There are so many things on your mind during the day! Within 30 minutes before going to bed, try not to think about any problems. You'll be able to fall asleep quickly!

The most common symptom of cataract is blurred vision, which may include fear of light, darker or yellow color of objects, and even double vision (double vision) and distortion of objects.

The clouding of the lens caused by various causes is collectively referred to as cataract. There are many causes of cataract, the most common being senile cataract, which is a normal physiological phenomenon that occurs with age. The incidence increases with age, especially in people over 60 years of age.

Cataracts can also be caused by other factors, young people, infants and young children. Cataracts that exist after birth or occur at an early age are called congenital cataracts; Traumatic cataract is called traumatic cataract when the lens breaks down and causes the lens to become cloudy. In addition, diabetes, intraocular inflammation, and bleeding disorders can also cause cataracts.

Cataract is a common ophthalmic condition and one of the leading causes of blindness.

**。There are two types of cataracts: non-surgical and surgical. Non-surgical**:

In the initial stage of cataract, eye drops such as catarrhalin and white arrest can be used to control the development. Surgery**: Cataract vision is below and surgery can be performed as long as the fundus condition is good and the symptoms of systemic disease are not obvious**.

How many types of surgery are there? At present, we mostly use two surgical methods: one is extracapsular cataract extraction, which is accompanied by a pair of glasses after surgery; The other is the most advanced surgical method in the world

extracapsular cataract extraction + intraocular lens implantation; You can return to your previous normal vision immediately after surgery. At present, our hospital has introduced the most advanced equipment and instruments in the world, with domestic first-class ophthalmology experts, cataract surgery with small incision, phacoemulsification, and the operation can be completed in 2 5 minutes. More than 8,000 cataract patients have been implanted with intraocular lenses, giving them back sight.

More than 90% of patients have postoperative visual acuity above.

Can cataracts be operated on in the elderly? Cataract surgery can be performed on people over 90 years old regardless of age, as long as they are in good physical condition. Because of the regain of sight after surgery, the mood is comfortable, and the life can be prolonged.

Two-thirds of the main causes of blindness are acquired, two-thirds of them are caused by acquired diseases, one-fourth is caused by accidents, and occupational disasters. In addition, it is due to congenital inheritance or pathology that causes blindness.

According to the survey, 2 out of 10 percent of the respondents lost their sight due to acquired diseases, 10.5 percent due to infection or fever, 8.75 percent due to retinal detachment and lesions, 2.5 percent due to glaucoma, and 7 percent due to optic nerve disease.

According to research, the highest risk of blindness occurs in infancy, then in adolescence and childhood, and the causes of blindness are congenital heredity or pathology, as well as acquired diseases and accidents.

Traffic accidents are an important cause of blindness, and the higher proportion of accidents occurs between the ages of 16 and 20 and between 26 and 35, and the highest proportion of occupational accidents is between 21 and 40 years old. <>

First of all, light impact will not cause retinal and corneal detachment, generally patients with retinal perforation are more likely to cause retinal detachment when doing strenuous exercise, retinal detachment is related to many factors, myopia, aphakic eye, age, retinal degeneration, trauma are predisposing factors for retinal detachment, people with the above symptoms are very likely to cause retinal detachment, retinal detachment can be achieved through retinal detachment reduction surgery after a comprehensive examination of the fundus, there is no corneal detachment in medicine, the cornea is divided into 5 layers, From front to back, it is the epithelial cell layer, the predescemet's layer, the parenchymal layer, the posterior elastic layer, and the endothelial cell layer, the epithelial cell layer and the predescemet's layer are loosely combined and easy to fall off due to injury, but the regeneration ability is strong, and it can be regenerated quickly after injury, leaving no scar, the predescemet's layer has weak resistance, it is easy to be damaged, and there is no regeneration ability, the parenchymal layer accounts for 90% of the corneal thickness, and it cannot be regenerated after injury, and it is replaced by scar tissue, and the posterior elastic layer has strong resistance, and it can be regenerated after injury, and the endothelial cell layer cannot be regenerated after injury. Damage to the cornea and detachment of the retina can lead to blindness, but retinal detachment can be repaired surgically, and vision can only be obtained through a corneal transplant if the cornea is irreversibly damaged.

Because the cornea has no blood vessels, the transplanted cornea will not be rejected by the body's immune system. However, the cornea has very sensitive nerve endings that, once touched, immediately trigger a blinking motion to protect the eye. A prerequisite for corneal transplantation is confirmation that the retina, optic nerve, and visual center of the brain are functioning properly.

Retinas generally don't need a transplant.

Corneal transplant materials can be divided into living donation and cadaver donation according to their **. The so-called living donation, as the name suggests, is a living person, due to trauma, optic nerve disease, intracranial disease and other reasons caused by blindness (no light sense), but the cornea is intact eyeball, are suitable donors.

However, at present, the vast majority of corneal transplant materials in China are still ** fresh cadavers (donors), generally 60 years old and cornea healthy people are suitable, especially those who die from acute diseases or trauma, among which between 18-35 years old are the best; Infants under six months of age and elderly people over 90 years of age are not suitable for donation because of poor corneal function. In general, it is valuable to remove within 6 hours after death and within 12 hours after death in winter, and it is better if the corneal epithelium is intact, the matrix is transparent, and the thickness remains unchanged (no edema), and if the fresh corneal material is specially treated with preservation solution or deep low temperature, it can be kept for several days or weeks and then set aside.
