Early symptoms of cataracts: Do you know about it?

As we age, lens protein aging is the main cause. Early cataracts can be unmanifested and can only be detected by eye examination. As the disease progresses, blurred vision gradually develops.

Usually, blurred vision is the main manifestation of cataracts. Some patients also present with a deepening of myopia or a decrease in the power of glasses. If complications occur, there will be complication symptoms, such as dilated cataracts can cause an acute attack of glaucoma, cataract symptoms are red eyes, eye pain, further vision loss, etc.

The early symptoms of cataract may be:1Blurred vision, 2

Tone change, 3Fear of light, 4Black dot in front of the eyes, 5

Double vision, 6Lens myopia, etc.7 The late symptoms are the deepening of visual impairment, and finally only the fingers can be distinguished in front of the eyes or only light vision remains. If you have already experienced the above related symptoms, you must go to the hospital for examination in time to confirm whether you have cataracts, and ** in time.

CataractsAlthough there is no drug that can completely effectively ** cataracts, it can be easily achieved through surgery. The Ophthalmology Center of the 254th Hospital of the People's Liberation Army uses cataract cold phacoemulsification plus intraocular lens implantation technology, which has the advantage that phacoemulsification can remove cataracts through an incision with a chord length of less than 3 mm, successfully helping hundreds of thousands of cataract patients to regain their sight.

Cataract is a common disease in people over the age of 40, and most of this disease increases with age. The cause of cataract may be caused by encephalogenetic or local nutritional disorders, immune and metabolic abnormalities, etc., which may cause metabolic disorders of the lens of the eye, resulting in degeneration of crystal proteins and cloudiness. Cataract patients will also have a lot of inconveniences in their lives, and the eyes are a very important part of the human body.

So what are the symptoms of cataracts?

Cataract is a relatively common disease among the elderly, most of the elderly will also suffer from cataract, cataract patients have more symptoms, the first is the gradual decline of vision, when looking at the outside world, it will feel very blurry. Normal people will see things very clearly, but cataract patients will feel that there is a piece of glass in the middle when they look at things, and everything they see is blurry and hazy. As the patient ages, this blurring may gradually worsen until it is finally difficult to see.

It is very likely that the aperture will also appear when looking at things, mainly because the lens of cataract patients becomes more cloudy, but some places are transparent, so there will be double vision or polyphus when looking at things.

If the elderly suddenly get better, it may be the cause of cataracts, and some cataract patients will not see things at night, and their vision will become very poor in dim light. Therefore, it is also recommended that if you have these symptoms, you must go to the hospital for **, especially for older people, and you must ensure that your Senzhao is in good health, so that your family can rest assured and you can have a happy life in your old age.

The most typical symptom of cataract is called ** and progressive vision loss, that is, the patient will have blurred vision. In the early days of Sidd, it was like living in a foggy day, which was called foggy vision. This gradual vision loss will gradually worsen, causing the patient to see less and more clearly.

However, during the whole process, the patient does not feel pain, does not have eye pain, eye redness, eye swelling or other uncomfortable symptoms, but the vision slowly decreases more and more, and then drops to the level of serious impact on life. Therefore, the symptoms of cataract are called **sexual, progressive vision loss.

I learned that this is an eye disease, and the symptoms are not obvious in the early days, but only a slight blurred vision, many people will think it is presbyopia, and later there will be glare, myopia, hazy feeling, and flying shadows.

The symptoms of cataract are decreased vision, blurred vision, photophobia, monocular double vision, and dark shadows in front of the eyes.

Early symptoms of cataracts:

1. Visual impairment; Clause.

2. Decreased contrast sensitivity; Clause.

3. Refractive changes; Clause.

4. Monocular diplopia or polyopia; Clause.

5. Photophobia and glare; Clause.

6. Decreased sensitivity of color vision; Clause.

7. Visual field defects. Early symptoms of cataracts:

1. Visual impairment; Opacity of the lens leads to visual impairment, which is related to the location and degree of opacity of the lens, with the peripheral part of the lens being clouded and the center being transparent, which has little impact on vision. If there is opacity at the posterior pole or **, it blocks light from entering the fundus and causes vision loss.

Clause. Second, the contrast sensitivity decreases, especially for high spatial frequencies. Clause.

3. Refractive changes; For example, in nuclear cataract, after the lens loses its elasticity, the refractive power of the lens to light increases, and the refractive force of the lens to light increases, resulting in nuclear myopia. Clause.

Fourth, due to the swelling or fracture of the lens fibers, the refractive power of each part of the lens changes inconsistently, resulting in different refractions, and patients are prone to monocular diplopia or polyopia. Clause.

5. The opacity of the lens scatters the light entering the eye, interferes with retinal imaging, and the patient will have photophobia and glare. Clause.

6. The color of the lens nucleus changes, which can produce visual changes. The cloudy lens absorbs blue light from the spectrum strongly, making the patient less sensitive to color vision. Clause.

7. Cloudy lens can produce different degrees of visual field defects.

The main symptom of cataract is visual disturbance, which is related to the degree and location of the cloudiness of the lens. Severe cataracts can cause blindness. Cataracts are divided into age-related (senile), traumatic, concurrent, metabolic, toxic, radiation, developmental and posterior cataracts.

Generally, cataracts can only be performed by surgery. Cataract surgery has made significant progress in the last 30 years due to the use of surgical microscopes, microsurgical instruments and intraocular lenses, as well as improvements in suture materials and local anesthetic methods. Cataract extraction** is often used, in which an intraocular lens is implanted in the eye or glasses or contact lenses are worn to correct vision.

Because the light entering the eye must pass through the lens, if the lens blocks the eye ray, or the eye line is deviated or diffused, vision can be affected. The degree to which vision is affected depends on the location and density of the opacity of the lens (cataract maturity). In bright light, the pupils are narrowed, the light channels of the eyes are narrowed, and cataracts are more likely to block the incoming rays.

As a result, many people with cataracts have worse vision in bright light. And halos, glare, and scattered light appear around the light. Blurred vision is especially noticeable when a person with a cataract enters a bright environment from a dark place, or when reading under a bright light.

Patients with both glaucoma and cataract may also have significant vision loss due to miosis. Clouding (posterior subcapsular cataracts), located behind the lens, also has a greater impact on vision in bright light. Because the posterior pole of the lens is the path through which light passes, this type of cataract is more likely to damage vision.

There is a nuclear cataract (cloudy from the center of the lens) that can be seen early as improved near vision because the nuclear cataract increases the lens's ability to focus and make it easier to see near objects. Most older people have difficulty seeing near objects due to presbyopia, and in the early years after cataracts, they are surprised to find that they can read without reading glasses, a phenomenon often referred to as second vision. Although cataract is generally the most common type, a small number of patients may have increased eye pressure due to swollen lens (glaucoma) and have eye pain.

What is a cataract?

Cataract is a disease that occurs in the lens of the eyeball, and the vision is affected by the cloudiness of the protein degeneration, and the vision is blurred when looking near and far. The normal human eye is transparent, but once the Jingnashi is mutated, it will block the light from entering the eye, and a gradual vision decline will occur, and the Nao King will eventually lose his friends completely.

The 5 most frequently asked questions about cataracts.

1. Cataracts are only available to the elderly?

Senile cataract is indeed the original mass of the aging of the eye-clear lens. But beware: cataracts are not exclusive to the elderly! At present, many young people in their forties and fifties have been diagnosed with cataracts because of blurred vision, so they should be more vigilant in their daily life.

2. Can cataract not be **?

If the cataract is not operated in time, the best time to operate will be missed, which will not only seriously affect the quality of life of the patient, but also may cause acute glaucoma and lead to irreversible blindness. In addition, the lens nucleus is too hard, and phacoemulsification may increase the thrust of surgery, which may increase the risk of damage to the eye.

The surgeon will make a decision based on your specialty, and you don't have to wait until the hole is "ripe" before the surgery, and the doctor will determine it based on your occupation and eye needs. It is generally believed that when the patient's corrected visual acuity is lower or the visual quality affects normal life, study and work, tiger surgery can be performed**. If it has been determined that it is a cataract, it must be early**!

3. Is it not suitable for the elderly to have cataract surgery on their own?

Some elderly people are worried about the dangers of cataract surgery as they get older, and they are very resistant to undergoing surgery**. At present, cataract surgery is very mature, as long as the top examination before the operation is qualified, the operation can be carried out normally, and there is no need to worry too much.

4. How easy is it after cataract surgery?

After cataract surgery, some patients will develop posterior cataracts, which can cause vision loss. Posterior cataract refers to the proliferation of residual cortical or crystalline epithelial cells after the removal of extracapsular entropy in cataract or trauma to the crystalline fairy, forming a mixture. If there are other causes of vision loss, transgated laser** can improve visual acuity, and patients do not need to worry too much.

5. How to maintain cataract after surgery?

1) Prevent postoperative infection and take medication on time according to the doctor's instructions.

2) Eat lightly, don't eat greasy and spicy food, and quit smoking and drinking.

3) Pay attention to the condition of your eyes after surgery and do not rub your eyes.

4) Timely review and regular follow-up: exercise appropriately, but do not do strenuous exercise to avoid eye trauma.

5) Pay attention to balanced nutrition and supplement vitamins in time.

Ophthalmology Panel:

The most common symptoms of cataracts are different for each patient: blurred vision, too much light, glare or halos, night blindness, double vision, fading color, increased myopia, need for new glasses, and distorted vision in both eyes.

In the early stages of the disease, there can be no changes in vision, and because cataracts develop slowly, vision loss is a gradual process. Some cataracts can cause a temporary increase in near vision, but as the cataract worsens, vision will also deteriorate further. Signs of cataracts can be similar to those of other eye diseases and should be diagnosed by an ophthalmologist.

The main symptom of cataract is blurred vision, which can include photophobia, dark or yellow color of objects, and even double vision and distorted vision. As cataracts progress, it can lead to nuclear myopia caused by changes in the refractive index of the lens nucleus, and the myopic eye needs to be replaced frequently due to the increase in myopia.

The main symptoms of cataract are gradual, progressive blurred vision, such as seeing things and objects darkly, feeling that there is a layer of fog in front of the eye, and even double vision and visual distortion.

The early symptoms of cataract include blurred vision, color change, photophobia, black spots in front of the eyes, diplopia, crystalline myopia, etc., while the late symptoms are the deepening of visual impairment, which can only distinguish fingers in front of the eyes or only the sense of light remains, until the final blindness, and the whole development process is slow. However, even when people are blind, they still have a sense of light, that is, they can distinguish between day and night.
