What are the dangers of cataracts to the eyes?

What are the dangers of cataracts to the eyes? Luoyang Boai ophthalmology experts said that there are two major categories of cataracts: congenital and acquired. Age-related cataract is common in daily life, what are the dangers of cataract to the eyes, let's take a look at the detailed introduction of Luoyang Boai ophthalmology experts!

The most common is senile cataract, which occurs at about 50 years old and is caused by degenerative changes in the lens. Cataracts that exist immediately after birth or occur at an early age are called congenital cataracts; Clouding of the lens due to eye trauma is called traumatic cataract; In addition, metabolic cataract caused by diabetes, parathyroid insufficiency, inflammation in the eye, hemorrhage and other diseases can lead to concurrent cataract. The harm of early cataracts is only to make the patient feel that there is a white fog in front of his eyes, and his vision is blurred. If cataract progresses to the middle and advanced stages, it will cause many serious complications, such as glaucoma, pigmentitis and so on.

Especially in a stage in the development of senile cortical cataract, medically known as the swelling phase, due to the accumulation of more water in the lens, it swells sharply and increases in size, making the anterior chamber shallow, and a small number of patients can cause intraocular pressure to rise, resulting in glaucoma attacks. The above is a detailed introduction to the problem of what is the harm of cataract to the eyes, we should do a good job in the prevention of the disease in time after understanding, for patients, the prevention of the occurrence of the disease is the most important, of course, you can consult our Luoyang Boai Eye Hospital ** experts to learn more.

1. Patients with early cataract will feel a white fog in front of their eyes and blurred vision.

2. If cataract develops to the middle and advanced stages, it will produce many serious complications if it is not timely, such as glaucoma, meningitis pigmentosa, etc. When patients develop eye redness, eye pain and headache, their vision will deteriorate dramatically or even lose their sense of light, and if they are not treated in time, it will cause permanent damage to the optic nerve, and even cataract surgery will not save vision. For cataract patients, surgery is the only option for cataracts.

1. The inability to take care of oneself due to illness leads to a serious psychological burden, and in severe cases, blindness, and the severity of the disease will make the patient bear a heavy psychological burden.

2. If the cataract is severe, it will directly lead to the patient's blindness, which will not only cause inconvenience and mental burden to the patient's life, but also bring pressure to the family.

3. If the blindness is caused by cataracts, the heavy psychological and mental pressure borne by the patient itself is much greater than that of the patient with congenital blindness.

4. If the cataract condition is serious, it will directly interfere with the patient's daily life, and even cause serious accidents to the patient.

Fifth, the vision is blurred, and you are often unable to take care of yourself in daily life, which may lead to some other complications.

Blindness caused by internal cataracts is only one result of cataracts, but the process of gradual blindness can be a toss-up. In fact, after the onset of cataracts, the complications caused by cataracts can cause far more profound pain to patients.

1. Monocular polyopia: In the early stage of cataract, the lens is partially cloudy and partially transparent, and the light projected on the retina through it will produce double or multiple shadows, thus producing monocular polyopia.

2. Diabetic retinopathy: Diabetic retinopathy is one of the common and serious complications of diabetes. At present, the incidence of diabetes in China remains high, and the prevalence of diabetic retinopathy is about 50% among urban diabetic patients.

The influencing factors are mainly related to the length of diabetes and the quality of diabetes control. In addition, the elderly with diabetes mellitus have a higher incidence of senile cataracts, which occurs earlier and progresses relatively quickly.

3. Shadow in front of the eye: In the early stage of cataract, part of the lens is clouded in the pupil area, and there can be punctate or patchy shadows with a fixed position and unchanged shape in front of the eyes. It is distinct from floaters caused by vitreous opacity, in which the shadows are movable, and although they do not have a large range of motion, they appear and disappear and change in shape.

4. Abnormal color vision: In the early stage of cataract, due to the swelling of the lens due to the absorption of more water, the gap between its epithelial cells is enlarged and filled with particulate water droplets, and the light will be refracted when it passes through it and show color halo.

In recent years, due to the improvement of people's living conditions and health level, the incidence of this disease has also increased year by year. It is thought that the disease is related to a variety of factors such as long-term chronic photodamage, genetics, metabolism and nutrition of the fundus macular in the fundus. It usually occurs in people over the age of 50.

Mostly binocular and with a slow and progressive decline in visual acuity.

1. If cataract patients are not timely, it can lead to blindness, or cause lens-solubilizing glaucoma or lens-allergic endophthalmitis, which must be paid great attention to by middle-aged and elderly people. Second, cataracts can develop and cause serious consequences. According to the characteristics of different stages of cataract occurrence and development, cortical cataract is usually divided into four stages:

Initial stage (peripheral lens opacity, generally does not affect vision), expansion stage (partial lens opacity, volume increase, anterior chamber shallow, this stage is easy to cause glaucoma); Mature stage (the lens cortex is all cloudy, milky white homogeneous, iris projection is negative, visual acuity is reduced to light perception or manual eyes), overmaturity stage (lens fibers are broken down into chyme-like fluid, the volume is reduced, the capsule is shrunk, there may be calcified spots, the nucleus sinks, or the lens is dislocated, and the cortical overflow). Once the patient is diagnosed with cataract by an ophthalmologist, he should regularly visit the hospital every 1-2 months to understand the changes in the lens. The prognosis of senile cataract will inevitably lead to loss of vision in terms of development; **In terms of the high success rate of surgery, especially in the absence of comorbidities, with the recent application of microsurgery and phacoemulsification intraocular lens implantation, most patients can recover useful vision.

Baoding Xinshi Eye Hospital.

1. When the cataract opacity lens develops to the pupil area, there will be visual loss of consciousness, blurred vision, monocular diplopia, polyopia, and dark shadows in front of the eyes. 2. When the cataract enters the expansion stage, the patient's vision decreases significantly, and there is eye swelling and pain, headache, colored aperture when looking at the light, nausea, vomiting, and sharp decline in vision in severe cases, and the intraocular pressure of a few patients increases, causing glaucoma. 3. In the mature and overmature period, the eyesight is seriously reduced, and the life can not take care of itself, and cause some serious complications.

4. If cataract causes glaucoma, the swollen lens must be removed in time, otherwise it may lead to blindness. In addition, if the cataract is not in the mature stage or overripe stage**, the vision will decline sharply until blindness.

Cataract is a common ophthalmic disease, and is currently the world's first approximately blind eye disease, more than 90% of cataracts are naturally caused by aging, and everyone will inevitably get cataracts at a certain age, and their vision will also decline. In addition, ultraviolet radiation, endocrine disorders (such as diabetes), myopia, and family genetics are all causes of cataracts. We can classify cataracts according to **:

1) Congenital cataract; (2) senile cataract (age-related); (3) concurrent cataracts; (4) metabolic cataract; (5) drug-toxic cataracts; (6) traumatic cataract; (7) Posterior cataract. At the same time, according to the severity, it can be divided into mild, moderate, and severe cataracts. Typical symptoms of cataracts are:

Blurred vision or double vision, reduction of presbyopia, dark shadows in front of the eyes, day or night blindness, abnormal color vision, etc.

Cataracts are caused by clouding of the lens. Because our lens also "retires", with the increase of age or trauma and other reasons, the lens of the human eye will gradually become cloudy, and light cannot be transmitted, resulting in vision loss. In other words, the culprit of cataracts is the lens.

Surgery is currently the only effective way to cataract, and phacoemulsification combined with intraocular lens implantation is the most common. In general, our intraocular lenses can be divided into three categories: monofocal, multifocal and continuous visual range intraocular lenses. Of course, not all cataract patients need immediate surgery, and it is necessary to go to a professional medical institution for diagnosis and examination to ensure the best results.

The main harm of cataract is to cause vision loss, and even unable to take care of oneself, and may also have secondary glaucoma, so the development of cataract to a certain extent requires a hospital examination, affecting daily life on surgery**.

According to incomplete statistics, there are about 10 million cataract surgeries every year. If senile cataract is not treated in a timely manner**, it may lead to secondary glaucoma and even permanent blindness.

Cataracts are classified as early, middle and late, and late cataracts can lead to blindness in the eyes.

At present, it is recognized as one of the blinding eyes, basically everyone reaches a certain age, lens aging, aging will cause cataracts, if not early, it is easy to cause many serious conditions, such as accompanied by glaucoma, or fundus lesions, blindness, headaches, etc., life can not take care of themselves, so it is recommended to detect early **, and the cost is less.

Suffering from cataracts, if not **, will lead to many complications, such as glaucoma, pigmentitis, etc., these eye diseases mostly occur in the middle and late stages of cataracts, not only cause blindness, sometimes cause severe inflammation, and some are accompanied by long-term eye pain, and even lead to eye atrophy, losing the best time. I recommend that you be prompt** and hope to help you.

Cataract is a common ophthalmic disease, is one of the important blinding eye diseases, more than 90% of cataracts are naturally caused by aging, many elderly people will have decreased vision after aging, if you miss the best time, it may lead to more serious consequences, if vision loss please go to a regular hospital as soon as possible.

The harm of cataracts is mainly to affect the patient's vision. Cataract is the first slow vision loss, patients will find unconsciously, the age of the vision will decrease, thought to be caused by the factor of age, often do not see the ophthalmology, so it will delay the opportunity. Current cataract surgery is very mature, early**, early benefit, and can achieve a higher quality of life.

Cataract is a common and frequent disease in ophthalmology, and cataract mainly refers to any congenital or acquired factors.

The hazards of cataract include: 1. Affecting the quality of vision, thereby affecting the quality of life; 2. Some cataracts can induce the formation of glaucoma, causing irreversible and sharp decline in the patient's vision, causing eye pain and headache. Due to the lack of understanding of cataracts, some patients have misunderstandings about cataracts and believe that they need to wait for cataracts to mature before surgery.

If cataract has caused vision loss and affects the quality of life, you should go to the hospital for examination as soon as possible, detect it in time and operate in time, and do not delay the best time.

Over time, it may cause the eyes to be completely unable to see.

Cataracts are mainly caused by severe visual impairment and, as the disease progresses, can lead to blindness when the cataract is severe enough to a certain extent. If the cataract is not too serious and does not affect normal life, you can temporarily skip surgery**, but if things are blurry and you can't see clearly, it is best to do surgery**, and phacoemulsification surgery is generally commonly used.

Cataract is a common eye disease in the elderly, with a high incidence rate, and has been known as the "killer" of eye health, mainly because of the high blindness rate of cataract. In addition, some eye diseases often cause cataracts.

Cataracts are caused by the clouding of the lens in the eye, which changes from transparent to opaque, preventing light from entering the eye, thus affecting vision. Initial cloudiness has little effect on vision, and then gradually worsens, significantly affecting vision and even blindness.

The main symptoms of cataract are: vision loss, blurred vision, due to the different location and degree of cataract, its impact on vision is also different, if the cataract grows in the periphery of the lens, vision can not be affected, if the cloudiness is located in the lens **, the light vision is reduced, and the severe vision may only see manual or light sense. 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.

The most effective method for cataracts** is surgery. With surgery**, the vast majority of patients are successful in regaining their vision. At present, the advanced cataract surgery technology, on the basis of relieving the vision loss caused by cataract and the risk of blindness, can also solve the patient's original myopia, presbyopia, astigmatism and other problems that affect vision, and many patients can recover their postoperative vision to about the same level as young people with good visual condition.
