What is floaters ? What is floaters

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.

Black dots appear in front of your eyes, just like mosquitoes, they will fly around with the movement of your eyeballs, and there are various shapes, such as round, oval, dotted, linear, and even cobweb-like, etc., when you look at the white background or the blue sky, you will find more of this floating object. Medically, we call this symptom "floaters", which is a typical symptom of many eye diseases or eye injuries.
