Can I still see cataracts What are the causes of cataracts?

The causes of cataract are related to many aspects, and the specific circumstances are as follows:

1. With the increase of age, the patient's lens becomes turbid, changing from transparent to opaque, causing cataract;

2. Cataract caused by diabetes, galactosemia or hypothyroidism;

3. Some patients work outdoors for a long time, and long-term excessive exposure to ultraviolet rays can cause cataract to occur prematurely;

4. Genetic factors can lead to cataracts;

5. Malnutrition can also cause cataracts;

6. Some patients are highly myopia, which can aggravate the turbidity of the lens and lead to cataracts.

Cataracts can affect vision. At first, vision is blurry, but it gradually progresses to affect eyesight and eventually lead to blindness. In particular, middle-aged and elderly people must pay attention to cataracts.

Sunlight and ultraviolet rays Over the years, it has been noted that sunlight is involved in the formation of cataracts in humans. Under the influence of ultraviolet light, phosphorus ions may combine with calcium ions in the aging lens to form insoluble calcium phosphate, which leads to hardening and calcification of the crystals. This is one of the most important cataracts.

The eyeball is like a camera, the camera lens is similar to the lens in the eye, it is a transparent biconvex lens, which can play a concentrating role in the image of the eye, if it causes the lens to be clouded, it affects vision, and cataract occurs. **There are physical, chemical, traumatic, poisoning, metabolic diseases, etc. From the perspective of blindness prevention and treatment, the World Health Organization believes that cataract is the first blinding eye disease, more than 46% of more than 40 million blind people are blinded by cataract, and there will be 40-1.2 million new cataract patients in China every year.

I know this disease very well because my relatives at home have this disease, which is an eye disease where there is a white covering on your eyeball that blocks your vision and affects the nerves in your eye, which can only be treated with surgery.

Cataract is caused by the clouding and whitening of the lens due to aging, physical damage, chemical injury, surgery, drug poisoning, metabolic diseases, or immune factors.

It may affect vision, and it is also a very common eye disease, and it requires surgery, and there will be obvious symptoms, and the incidence rate of the elderly is very high.

The main symptom of cataract is vision loss, blurred vision. In addition, it can also be manifested as a deepening of myopia, which requires frequent and frequent changes of glasses; Monocular diplopia or polyopia, fixed dark shadow or dark vision in front of the eyes, photophobia, etc., and in general, there is no redness and pain in the cataract eye.

Cataract is mainly caused by the clouding of the lens, and eye injury, aging, and genetics can also cause cataracts; After suffering from cataract, it is necessary to seek medical attention in time, carry out medication** or surgery**, drugs can be used in the early stage of cataract to delay the development of cataract, and surgery can be performed after the cataract is advanced to the advanced stage**.

The first point is likely to have inherited genes to have such a disease, the second point is very wild, which may have retinal problems, so it will get such a disease, and the third point is that the best way to do it without cataract is to go through the hand spine surgery to achieve good results.

It is mainly caused by retinal detachment. The lead grip can usually be used with medication** or with the help of dietary therapy**. Eat more light food during the celebration of peace, and the feast will be excited.

1. Senile cataract: It is an age-related cataract, which is mainly caused by the denaturation of protein, the increase in the content of insoluble protein, sodium and calcium, the decrease in potassium and vitamin C, and the lack of glutathione. 85% of the lens protein is water-soluble albumin, which can be converted into insoluble protein, and the older you are, the more insoluble protein content there is; In addition, vitamin C deficiency, changes in the pH value of the crystal, and the infiltration of some toxic substances into the crystal can cause the denaturation of the crystal protein and produce turbidity.

2. Traumatic cataract: common car accidents, blunt force injuries, sharp object puncture wounds or penetrating eye foreign body injuries, etc. 3. Concurrent cataract:

Including mechanical, radiation, electric shock, lens opacity caused by certain eye diseases themselves, such as iris cyclitis, choroiditis, retinal detachment, retinitis pigmentosa, glaucoma, high myopia, purulent corneal ulcers, old eye trauma and other eye diseases can cause concurrent cataracts. 4. Metabolic cataract: diabetic cataract is more common in clinical practice.

5. Congenital cataract: also known as developmental cataract, there are two types: endogenous and exogenous. Endogenous causes are related to fetal developmental disorders and are hereditary; Exogenous causes refer to the damage to the lens caused by systemic lesions of the mother or fetus, such as viral infections such as rubella, measles, chickenpox, mumps, hypoparathyroidism, malnutrition, vitamin deficiency, etc., which may be caused by the mother in the first 6 months of pregnancy.

6. Posterior cataract: caused by turbidity of the residual cortex and capsule after cataract extracapsular extraction or linear extraction. 7. Drug-induced toxic cataract:

Caused by long-term and large use of topical or systemic corticosteroids in the eye. 8. Radiation cataract: mostly caused by radiation.

At present, the mechanism of cataract formation is not very clear, and it may be related to nutritional metabolism, environment, genetics and other factors, such as congenital cataract may be related to genetic factors, and age-related cataract is usually considered to be related to excessive exposure to ultraviolet rays, diabetic patients or frequent diarrhea leading to malabsorption of nutrients, and long-term local or systemic application of large doses of adrenal corticosteroids. Concurrent cataracts may be related to diseases in the eye, such as uveitis, glaucoma, retinal detachment, retinitis pigmentosa, high myopia, etc. In addition, traumatic cataracts can occur after eye trauma, and cataracts can also occur after ionizing radiation.

1.Senior citizen.

With the increase of age, the function of the elderly in all aspects of the body begins to weaken, the function of the lens is also relatively weakened, coupled with the influence of metabolism and other factors, the chance of cataract is relatively increased.

2.People who have been exposed to ultraviolet rays for a long time.

Long-term exposure to sunlight will affect the redox process of the lens, causing denaturation and turbidity of lens proteins to induce cataracts.

3.People with a family history of cataracts.

Like many diseases, cataracts have a certain family genetic predisposition, so people with a family history of cataracts should pay more attention.

4.People with eye diseases or systemic diseases.

For example, people with uveitis or diabetes, high blood pressure, arteriosclerosis, and problems with lens nutrition and metabolism are all at high risk of cataracts.

5.Those who have been taking hormone drugs for a long time.

It may accelerate the growth of the lens, causing cloudiness and visual impairment.

6.People with high myopia.

People with high myopia develop cataracts early.

1.Congenital cataract, also known as developmental cataract, mostly exists before and after birth, mostly quiescent, can be accompanied by hereditary diseases, there are two categories: endogenous and exogenous, endogenous and fetal development disorders, exogenous is caused by damage to the lens caused by systemic lesions of the mother or fetus, congenital cataract is divided into anterior cataract, posterior cataract, circumnuclear cataract and total cataract.

2.Acquired cataract after birth due to systemic diseases or local eye diseases, abnormal nutritional metabolism, poisoning, degeneration and trauma caused by lens opacity, divided into 6 types:

Senile cataract, the most common, also known as age-related cataract, is more common in people over 40 years old, and increases with age, and is related to many factors, such as the slow metabolism of the elderly is related to degenerative changes, and some people believe that it is related to long-term sunlight exposure, endocrine disorders, metabolic disorders and other factors, according to the location of the initial opacity can be divided into two categories: nuclear and cortical.

Concurrent cataract (complicated by other eye diseases).

Traumatic cataracts.

Metabolic cataracts.

Radiation cataracts.

Drugs and toxic cataracts.

Generally, only surgery can **cataract**, if you have similar symptoms, it is recommended that you go to the hospital in time**.

Hello many reasons, it is a number of factors can be caused, it turbidity (cataract) of this situation, like congenital genetic factors, radiation, and then a UV light, is the strong sunlight this radiation, just like the Qinghai-Tibet Plateau, the closer to the sun, the incidence of cataract is higher than that of our coastal areas, as well as traumatic factors, and another is metabolic malnutrition, these factors can occur, the most common is senile age-related factors, that is, we are old, Almost everyone has to get it, but the age of onset is sooner or later, and the older you are, the higher the rate, and by the time you are over 60 years old, the incidence rate can reach 40 or 50 percent.

There are so many causes of cataracts. In general, cataract caused by age metabolic dysfunction in the elderly is the most common, which is "senile cataract", other systemic diseases such as diabetes mellitus are often complicated by cataract, local trauma of the eye is an important cause of secondary cataract, and cataract will inevitably occur when a perforated foreign body enters the lens, that is, or no perforated eye contusion can also cause cataract. Secondly, intraocular inflammation (e.g., uveitis) and intraocular diseases (e.g., retinal detachment, intraocular tumor) can cause cataracts.

Yes, there is a kind of cataract is diabetic cataract, in terms of diet, you have to drink more water, white water, tea, it is best to buy a jam machine, squeeze your own juice to drink, not only to replenish water, but also to supplement vitamins. It is also necessary to supplement protein, in addition to eating some cod liver oil regularly, also often eat some chicken liver, lamb liver, pork liver, carrots, coriander and other food oils, because vitamin A must be dissolved in fat to be absorbed. It is also necessary to supplement vitamin C, which can reduce the damage of light to the lens and has the effect of preventing the formation of senile cataracts.

In terms of **, it is necessary to seize the ** opportunity as soon as possible and not drag it out to the late stage. You can use functional eye drops, such as Shapu Aisi eye drops, which have a good reputation at present.

As we age and our bodies age, most people will suffer from cataracts. It is caused by normal physiological aging, and the difference is only the time of onset.

There are many causes, the most important being older age, as well as metabolic abnormalities and other causes of trauma. Now the only **method is surgery, conservative**cannot**.

There are many causes of cataracts, there are children born with cataracts, called congenital cataracts, which are related to eye dysplasia, and if the congenital cataract is more serious, it should be operated on as soon as possible. Age-related cataract is common in the elderly, which is a cataract formed by the gradual opacity of the lens as we age, and surgery can be considered if it affects vision. The most common is traumatic cataract, which is caused by the impact of a foreign object on the eye, causing the lens to be opaque and cloudy, resulting in traumatic cataract.

There may also be systemic diseases, such as metabolic cataracts caused by diabetes, which can be observed and surgery is required if vision is severely affected**.

Cataract is actually the clouding of the crystal, the lens is like a camera lens, it is transparent, and the light and things outside the eye enter the eye, and the lens is projected onto the retina, so that you can see things clearly.

Cataract can be operated on**, cataract is a very common disease in ophthalmology, according to the different categories, such as senile cataract, metabolic cataract, concurrent cataract, toxic cataract, congenital cataract, etc. The type and presentation of each cataract may be slightly different, but the clinical symptoms are generally vision loss. For cataracts caused by various reasons, the current ** plan is the same, mainly through surgery ** to restore vision.

The incidence of cataract in the elderly is high, but it is complex, and there is no complete conclusion at present, so drugs cannot ** cataract. Sunlight and ultraviolet rays, nutrition, lack of oxygen, smoking, other physical diseases, and long-term work and life in a hot environment can cause the lens to become cloudy and form cataracts.

What causes cataracts? Various causes such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolism disorders, resulting in lens protein denaturation and clouding, leading to cataracts.

Causes of cataracts.

1) Nutrient metabolism: Through animal observation, it has been found that certain vitamin and trace element deficiencies are related to cataract formation.

Sunlight and ultraviolet rays.

3) Outside temperature: foreign scholars have surveyed that the incidence of cataract in workers over 60 years old who work in high temperatures is significantly higher.

Anoxia. (5) Endocrine: Endocrine disorders can promote the production of cataracts, which is enough to explain that cataracts occur higher in diabetic patients than in ordinary people.

6) Hardening and dehydration: In the case of dehydration, the body fluid metabolism is disordered, and some abnormal substances will be produced to damage the crystals. Animal experiments have proved that after hypertonic dehydration, the crystals appear empty.
