What are the symptoms of eye cataracts?

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.

Extracapsular enucleation is one of the methods of cataract surgery, although it has the disadvantages of long operation time, large incision, easy to produce astigmatism, silk suture closure, and slow postoperative recovery, but due to the advantages of less investment and lower surgical cost, it is still the main cataract surgery method in underdeveloped areas and hospitals.

1.Incipinent stage: grayish-white opacities mostly appear in the deep part of the equatorial olfactory cortex of the lens first, which is wedge-shaped and arranged in a radial shape, and the visual acuity is not significantly affected when the opacity does not affect the pupillary area.

2.The expansion stage is also known as the developmetal stage: the wedge-shaped turbidity is gradually carried out, and other parts of the crystal also appear of different thicknesses, forming a different turbidity zone.

The cortical layer is in a state of expansion due to the increase in water, which causes the crystals to swell. At this time, the anterior chamber becomes shallow, and the crystal often has a uniform texture and a filamentous luster. Because there is still a layer of hyaline cortex under the anterior capsule, iris projection can be seen when obliquely illuminated.

At this stage, glaucoma quality may lead to glaucoma. By this time, vision loss has become noticeable and progressively worse.

3.Immature stage: After months or years, the excess water contained in the crystals gradually subsides, and the swelling disappears. The crystals are all cloudy, and the iris shadow disappears. This stage of surgery is ideal.

4.Hypermatue stage: The length of the maturity stage is variable.

If it is too long, the water is absorbed, and the star-shaped pattern of the crystal is lost, turning into a consistent gray-white color, or there are irregular small white spots on the gray-white cloudiness. The crystal fibers liquefy into emulsion, and the brownish-yellow crystal nucleus sinks underneath, which is called the Morgagnian cataract.

There are many causes of cataract, the most common is 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. The main symptom of cataract is blurred vision, which can include fear of light, darker or yellowish vision, and even double vision (double vision) and distortion of objects.

At present, there is no drug that can effectively prevent and delay the occurrence and progression of senile cataracts, and surgery** is the only effective method.

Guidance: Unilateral or bilateral, sequential, progressive loss of visual acuity, may have a sense of glare, or monocular diplopia, myopia increases.

In the early stage of eye cataract, presbyopia is usually reduced, blurred vision, and dark shadows in front of the eyes.

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.

Wouldn't you know if you went to the hospital?

Vision loss, blurred vision.

Six major symptoms in the early stage of cataracts:1blurred vision; 2.

monocular polyopia; 3.abnormal color vision; 4.night blindness; 5.

Shadows in front of you; 6.The symptoms of presbyopia in the eyes are reduced. If this happens, it means that there is a cataract.

I also want to consult you, cataract, generally due to the aging of the body, local nutritional disorders and other factors caused by lens metabolism disorders, causing lens degeneration and opacity, light can not be projected on the retina is easy to cause blurred vision, some people have no symptoms in the early stage, some will have progressive vision loss, blurred vision, foggy feeling, some people are also accompanied by dizziness and photophobia, etc., it is recommended to go to a regular hospital for ophthalmic examination as soon as possible to confirm the diagnosis, early cataract is recommended to be controlled, After rigorous phase III clinical research, class II new drugs, and listed companies and large enterprises, cataract is the degeneration of lens protein to form turbidity, which is generally manifested as double vision, black shadow, small black spots in front of the eyes, rainbow circles when looking at lights at night, etc.

Early symptoms include blurred vision, objects that are not bright enough, the lens that is partly cloudy and partly transparent, and day or night blindness.

Progressive vision loss, which is one of the most obvious and important symptoms of cataracts. Some people may not have as good vision in bright light as they do in low light.

Symptoms such as glare, color vision changes, visual field defects, monocular diplopia or polyopia, and some people may feel that their vision has suddenly improved, and their presbyopia has decreased.

Patients may feel that there is a layer of fog in front of their eyes, that everything is gray and misty, and that they may appear in a fixed position in front of their eyes.

Cataract is a common eye disease, people should take good care of their eyes, and don't let cataract affect your healthy life.

Depending on the type and course of cataracts, the symptoms of cataracts will vary. Cataract is an eye disease in which the lens protein is denatured due to various reasons, and the lens is cloudy and causes blurred vision. It is divided into congenital cataract and acquired cataract.

There are many causes of the disease, such as aging, genetic, immune and nutritional disorders, trauma, etc. The main symptoms are blurred vision, progressive loss of vision, glare, and double vision.

The early symptoms of cataract are blurred vision, such as double vision in one eye, day blindness, and night blindness.

In the case of cataracts in elderly patients, the contrast of objects with similar colors will be reduced and the distinction will be blurred. Some older people with cataracts also experience a decrease in presbyopia.

Patients with cataract should pay attention to it and go to a specialized hospital in time to actively cooperate with the diagnosis and treatment, so as not to delay the condition.

Not all cataracts can damage vision or interfere with daily activities. Some people have mild symptoms that are difficult to detect.

Glare and double vision of lights or sunlight.

Blurred vision, double vision, hazy or hazy.

Glasses need to be changed frequently.

Near vision improves for a short period of time and then gets worse.

Severe cataracts can cause vision loss in middle-aged and elderly people, affecting driving, work, reading, etc.

How does the disease progress after having a cataract?

Cataracts usually don't severely affect vision, and many don't require surgery**.

Cataracts can lead to glaucoma.

As the cataract progresses, more areas of the lens become cloudy. When the entire lens is white, it is called a "mature cataract" and can cause serious vision problems. Blindness may occur in some people, but this is rare.
