What kind of people are susceptible to floaters?

Floaters often occur in middle-aged and elderly people over 40 years old, and patients with high myopia, as well as those who have undergone cataract surgery, and other patients such as intraocular inflammation or retinal vascular disease can also form this disease. Most floaters are benign, or "physiological floaters", which are "good mosquitoes", and only a few will pose a serious threat to the eyeball, which is "bad mosquitoes". Experts believe that about 80% of floaters are formed by the hydration of vitreous fibers, that is, benign.

The characteristics of "good mosquitoes" are simply as follows: if the patient has floaters in both eyes, it is impossible to determine which eye has floaters, and if these phenomena do not aggravate or change after a period of time, and the position of floaters is fixed, it is mostly benign.

There are many reasons for the appearance of floaters, long-term excessive eye use or serious eye fatigue will affect the health of the eyes, and will also lead to the problem of floaters.

1. Elderly: age-induced degeneration is the most common reason, due to the age, the vitreous is not nutritious, and long-term light can cause the increase of oxygen radical content in the vitreous cavity, thereby causing the degradation of sodium hyaluronate, so that the collagen fibers in the vitreous are attached together, causing the collapse of the vitreous collagen and the liquefaction of the vitreous.

2. People with high myopia: China is a big country with myopia, and now more and more young people are very myopia, resulting in elongated eyeballs and insufficient vitreous nutrition, resulting in diseases similar to senile vitreous degeneration and vitreous opacity.

Mainly the elderly, and there are also people who usually use too many computers.

1. Physiological floaters.

Physiological floaters are caused by the vitreous humor in the eye.

Cortical cells are projected on the retina.

This is a natural condition of the human body. It usually occurs after the eyes are tired or focused for a long time, because the eyes stay in one place for a long time, which will cause the cortical cells in the eyes to shed faster, resulting in shadows in front of the eyes.

2. Pathological floaters.

Pathological floaters are generally caused by severe diseases, which may be due to lesions in structures such as the retina or carryover, which liquefies the vitreous and produces some turbidity. This condition indicates that the eye has been damaged and should be prompted, otherwise it is likely to be a real threat to vision.

So, how can you tell if the floaters you get are physiological or pathological? If you have any of the following conditions in your eyes, you should go to the hospital for a check-up in time.

1. Frequency of occurrence.

Physiological floaters are generally caused by eye fatigue for a short period of time.

After a short rest, the situation will be alleviated. And if you don't overuse your eyes again, it generally doesn't appear all the time. However, if it is pathological floaters, the number of scandals will continue to increase in a short period of time, that is, it is obvious that the condition has worsened.

2. Abnormal flash.

In general, the main symptom of floaters is the appearance of black spots flying in front of the eyes. Don't worry too much about this situation, because it generally means that these mosquitoes are"Good mosquitoes"。If these mosquitoes deteriorate, then in addition to the appearance of black spots in the eyes, there will be bright flashes of light, which should be accepted in time**.

3. The line of sight is blocked.

The small black dots produced by physiological floaters are very faint and do not affect the vision too much. But in the case of pathological floaters, then the entire view will be obscured by a bright flash, except for small black dots. At this time, it is necessary to consider whether the lesions in the eyes are starting to develop.

All in all, it is not too much of a problem to have one or two floaters once or twice, but it is also necessary to learn to distinguish between physiological floaters and rational floaters so that you can get them in time**. After all, the eyes are very important to the body, and if vision is destroyed, then the quality of life will also be seriously affected.

Floaters are the vitreous in the human eye, due to various reasons to lesions, the appearance of opaque turbidity, vitreous turbidity, under the irradiation of light, projected on the retina to form a shadow, manifested as when people look at things, there is a feeling of mosquitoes flying in front of the eyes, the vitreous is the gelatinous body between the lens and the retina, under normal circumstances, it is colorless and transparent, showing semi-solid gelatinous, mainly focusing on the effect of external light.

Symptoms of floaters:

Floaters are medically known as vitreous opacity, which is divided into two types: physiological and pathological due to the degeneration and liquefaction of the vitreous.

1. Simple vitreous liquefaction: it can be temporarily observed or treated symptomatically with drugs.

2. Vitreous opacity with retinal degeneration and tears: pupil dilation, detailed fundus examination, fundus retinopathy should be treated as soon as possible to avoid serious fundus complications such as retinal detachment.

Floaters. It is a relatively common ocular symptom that usually manifests as a clear, black filamentous or fly-like shadow-like material fluttering in front of the eyes of the eyes, which does not affect vision. Floaters is a manifestation of vitreous liquefaction, which is a relatively large structure in the eye, composed of collagen fiber tissue, which can play a role in supporting the eyeball, in fact, there are no blood vessels and nerves in it, and it mainly plays the role of supporting the eyeball.

The vitreous begins to liquefy from around the age of 4, and almost 20% of the vitreous will liquefy by the age of 20. At the same time of liquefaction, the gel state tissue in the vitreous will be dehydrated and shrink, and the collagen network structure will collapse, and after the collapse, a small section of the collagen network structure will float in the liquefied vitreous, so you can see a performance similar to a small mosquito or a small fly flying around. Floaters will be slowly absorbed and metabolized, that is, the skeleton of these collapsed collagen fibers can be slowly absorbed and metabolized over time.

The appearance of floaters does not affect vision, if you find that the dark shadow in front of your eyes has a certain impact on your vision, you should go to the ophthalmologist to rule out fundus disease.

What is "floaters"? Floaters are translucent or black floaters that appear in front of your eyes, which may be dots, threads, sheets, or rings, as if mosquitoes or flies are flying around in front of your eyes. This is a hassle that a lot of people have to run into.

In the case of high myopia, or with age, the vitreous humor will gradually degenerate, and at the interface between the glia and the liquid, the concentrated and concentrated glia will produce shadows cast on the retina, thus forming the symptoms of floaters. In addition, people with diabetes, high blood pressure and other diseases are also prone to "floaters".

The main manifestation of floaters is the presence of dark shadows fluttering in front of the eyes, especially in bright backgrounds or in well-lit environments. Floaters themselves do not affect vision, nor do they cause harm to eye health, so don't worry too much, if floaters are not serious, they don't need special treatment.

If the degree of floaters is more severe and affects normal life, work and study, oral lecithin complexed iodine can be used to promote vitreous opacity absorption, this drug can not be used for patients with thyroid disease and iodine allergy, usually about two to three months of medication The symptoms can be significantly improved.

Floaters are a common eye disease characterized by shadows in front of the eyes that move in response to eye movements.

Floaters are the presence of a gray shadow in front of the eyes that resembles a fly wing or a mosquito wing. Most of the time, the general manifestation is to look at the blue sky or look at a white wall, the symptoms of this floater are more likely to occur. Generally, it is due to a local degeneration of the vitreous, or with the increase of age, the vitreous also has degeneration or the posterior detachment of the vitreous part and the eyeball wall, resulting in floaters.

General floaters are not harmful to eye health, and there are no general special drugs. In recent years, some have developed laser ** vitreous opacity, which can improve floaters. On the other hand, when there is no floaters, there is also a condition that affects vision and blurred vision, you must go to the ophthalmology department and do an ophthalmic examination to rule out some exudation caused by vitreous hemorrhage or inflammation of the vitreous and retina in the back, and there will also be this symptom of floaters at the same time, so as not to be confused with physiological floaters and avoid further deterioration of the disease.

Floaters are called vitreous opacities in clinical ophthalmology, and there are physiological floaters and pathological floaters.

Physiological floaters is the degeneration of the vitreous, with age, the vitreous gradually liquefies, denatures, resulting in the vitreous detachment, the vitreous condensation, the concentrated gel floats into the field of vision, and the appearance of dot-like floaters in front of the eyes, which is physiological floaters, which will not have a great impact on vision and does not require special **.

If visual disturbance occurs, lecithin complexed iodine tablets and compound thrombotong capsules can be taken orally to promote vitreous opacity absorption.

If the detached vitreous body stretches on the retina, the vision may be lightning. When the traction leads to the rupture of blood vessels, the production of vitreous hemorrhage, the appearance of red smoke-like symptoms, and when the excessive traction leads to the formation of retinal tears and retinal detachment, there will be black shadows fluttering in front of the eyes, and the vision is blocked, which is pathological floaters.

When you look at bright places, white walls, and blue skies, you can see insects and thread-like things flying in front of you, and you can feel them moving with your eyes, and they don't disappear when you blink, but you can't feel them in dark places. This sensation of "floaters" in front of your eyes is called "floaters".

Normally, most of the eyeball is filled with a gelatinous transparent substance called vitreous. Light passes through the cornea, the lens, and then through the vitreous to the retina. However, if for some reason there is a "cloudiness" in the vitreous humor, you are looking at the bright background, and this "cloudy" shadow will be reflected on the retina and move with the movement of the eyeball, allowing you to see "floats" such as bugs or threads in front of you

flying, thus creating the sensation of floaters. This vitreous "clouding" and the resulting floaters have both physiological and pathological causes. Therefore, in medicine, they are called physiological floaters and pathological floaters.

Floaters, also known as vitreous opacity, is an ophthalmic disease, often occurring in middle-aged and elderly people, mostly related to vitreous liquefaction, or posterior vitreous detachment, because there are black spots floating in front of the eyes, so it is called floaters. This disease is a physiological degenerative disease, and it is generally not necessary to undergo **, and it is enough to go to the hospital for eye examination regularly.

Floaters are actually the opacity of the vitreous, which part of the eyeball is the vitreous, the eyeball is spherical, and most of the inside of the spherical is composed of the vitreous, which is like the jelly you usually eat, forming a jelly-like structure. However, with the growth of age, or high myopia, and the growth of the eye axis, the collagen structure in the vitreous humor is gradually damaged, and water is precipitated from it, in which the reticular structure is actually a network formed by a lot of collagen, and the water molecules gather next to the collagen mesh to form a jelly. But if the water molecules and the mesh structure are separated, only the water and the mesh structure can be seen, and the mesh structure looks like a small mosquito, like a floater, which is the origin of floaters.

Floaters are small black shadows in front of the eyes, especially on a bright or white background, which are more pronounced and occasionally accompanied by flashes of light. Floaters are generally caused by the liquefaction of the vitreous, or the posterior detachment of the vitreous, under normal circumstances, the vitreous is a transparent glue-like object, with the increase of age, the vitreous gradually forms a water-like change and liquefaction, with the rotation of the eyeball and shakes, the retina is stretched, becoming a black shadow in front of the eyes.

Usually, the black shadow in front of the eyes in the process of vitreous change generally does not affect vision, and normal people will also find when they look at the white background and blue sky, there are fluttering small black shadows or filamentous shadows in front of them, and sometimes they will see it when they close their eyes, but this kind of examination can not find any changes in the vitreous humor, and this phenomenon is physiological.

Floaters are a manifestation of vitreous aging, and the symptoms are not obvious and can be dispensed with**. If there is obvious obstruction of vision, too many floaters can be given oral iodine preparations or eye drops, iodine intake can be increased in the diet, and vitreous ablation can also be performed**. Floaters are vitreous opacities, divided into physiological opacities and pathological opacities, physiological opacities are common in high myopia, or the elderly, the vitreous itself is a jelly-like substance, the water content is very small, with the increase of water content due to age or other metabolic abnormalities, the vitreous gradually liquefies and appears turbid, if the turbidity is in the visual axis, the conscious symptoms are obvious.

Pathological opacity is due to eye diseases such as uveitis and trauma, resulting in abnormal exudate from the vitreous, etc., which affects vision in severe cases and needs to be carried out for the primary disease.
