Floaters. Black dots will appear in front of the patient's eyes, and they will fly around with the movement of the eyeball, like floaters, and their shapes can be round, oval, dotted, linear, etc. It is common for patients to see it more easily when they look at a bright background such as a blue sky or white wall.
Floaters often occur in middle-aged and elderly people over 40 years old, patients with high myopia, and people who have undergone cataract surgery, and other patients such as intraocular inflammation or retinal vascular disease. Most of the floaters are benign, or "physiological floaters", which are characterized by the fact that 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 location of floaters is fixed, it is mostly benign.
On the contrary, if the floaters occur suddenly, and they are limited to one eye, the direction of the mosquito flight is uncertain, the black shadow covers the field of vision, the vision deteriorates, and the vision is defected, which are all signs and danger symptoms that must be paid attention to.
Here are a few dangerous symptoms of floaters: (1) Abnormal flashes of light. (2) Floaters are increasing in a short period of time.
3) The view is obscured. Since a small number of floaters are a sign of a serious disease, experts believe that if you find a swarm of floaters dancing in front of your eyes, you should first do a specialist examination, and after the examination, if you unfortunately have a serious eye disease, then you should target the eye disease**. But the result of one test does not mean that there will always be no problems.
If there is a flash of light, a sudden increase in floaters, or the vision is obscured, it is necessary to undergo a detailed examination immediately. Floaters are small dark shadows that flutter in front of the eyes, especially when looking at a bright white background, and may be accompanied by a flash of light. Vitreous liquefaction and posterior dislocation are the main causes of floaters.
This is caused in 70% of patients, but 1 in 4 patients may have sight-threatening lesions, the main of which is retinal tear formation. When eye floaters are seen, the fundus should be carefully examined with dilated pupils, including slit lamp three-way mirroring, only posterior vitreous detachment does not require special **, and lesions that are harmful to vision should be followed according to relevant principles**. Floaters caused by intraocular inflammation, feeling that the dark shadows in front of the eyes are mostly dusty or flocculent, vision can be affected to varying degrees, the vitreous body under the ophthalmoscope has dusty, flocculent floaters, and pathological changes such as exudation caused by choroidal inflammation in the middle and periphery can be seen in the three-way lens of the slit lamp.
Floaters caused by intraocular hemorrhage feel like clouds of smoke moving or inky black shadows in front of the eyes, individual red or orange floaters, flaky flocculent, mass bleeding of varying thickness in the vitreous under an ophthalmoscope or slit lamp, and seeing the primary retinal lesions causing the hemorrhage. Hemorrhage due to posterior vitreous detachment of traction vessels is often accompanied by retinal tears and should be noted. If it is floaters without pathological changes, it is recommended to take a look at traditional Chinese medicine, and the efficacy of traditional Chinese medicine cannot be ignored.

Disease analysis: The occurrence can occur under the influence of senile, high myopic vitreous degeneration, or inflammation, bleeding, trauma, foreign body and other factors, hyaluronic acid in the vitreous depolymerization, precipitation of bound water, and the formation of a liquefaction cavity. At the same time, the collagen fibers that make up the vitreous scaffold mesh are denatured, concentrated and agglutinated to form a turbidity.
Suggestions: For physiological vitreous opacity, there is no need for **, it can be observed. For pathological ones, identify the cause and target it.

Floaters are one of the diseases of modern civilization!Because modern people's lives are inseparable from 3C products such as mobile phones and computers, and the time spent using 3C products is getting longer and longer, it is common to overuse the eyes, which also makes eye lesions report early.
Floaters are not a disease, but a natural physiological response to vitreous degeneration of the eye, which occurs early when we get older, myopia, have had surgery on our eyes, or stare at computers and mobile phone screens for a long time. In addition, it may be accompanied by retinal detachment, retinal tear, retinal vascular blockage, diabetic retinopathy, etcetc.
The vitreous humor of the eye is like a transparent gelatin, which gradually dilutes into water after degeneration, and the vitreous becomes cloudy, sometimes condensed into tiny granules or lumps, and after the light is cast, it causes shadows, and you will see small black dots dangling in front of your eyes. According to statistics, 15% of people between the ages of 20 and 29 have vitreous hydration, and those over 70 years old have vitreous hydration.
Degeneration (75%):Most people over the age of 40 have only a little in front of their eyes, which is seen by the retina due to the separation of the vitreous humor from the retina after degeneration.
Physiological (20%):Most people under the age of 40 and see a few points in front of their eyes, which are indeed just impurities that are naturally formed by the physiological nature of the eyes.
Pathological (5%):At this time, the patient feels that there are dozens to hundreds of floaters, which represents the diseased floaters and mountain diseases, and the doctor mainly wants to find out this kind of floaters, because this kind of floaters is the greatest threat to vision.
Sesame shape Insect shape Linear oval oval annular But everyone's symptoms are different, some people will see small black dots or small flying insects, and even large areas of black shadows like clouds, ink covering the vision.
Middle-aged people over 40 years old, people with high myopia, people who have had eye surgery, people who have injured their eyes, diabetic patients, patients with intraocular inflammation or retinal vascular disease, can also cause floaters. If you find floaters while reading or working, first avoid the background that is too bright, and move your eyes up and down, left and right, to temporarily remove the floaters. However, if the following changes occur, it may be necessary to seek medical attention:
The number of floaters increased overnight, not only black shadows, but also unknown flashes of light around The area of black shadows suddenly became larger, and the eyesight was suddenly unknown.

Problem analysis: Hello, floaters are generally caused by vitreous degeneration, which is a natural aging phenomenon, and many floaters exist for a long time, unchanged all year round, and do not affect vision.
Suggestions: It is recommended that floaters be divided into physiological floaters and pathological floaters. Although physiological floaters are difficult to find, they do not require any medication and may occur due to excessive eye use and long-term psychological depression.
Therefore, patients with physiological floaters only need to pay more attention to eye health, do more outdoor exercises, and practice gymnastics, which can increase their own immunity.

The eye can not focus on seeing things, which generally refers to the inability of the eye muscles to adjust normally when looking close, which may be caused by abnormal nerve conduction pathways from intracranial to ocular innervation, or abnormal function and degeneration of the ciliary muscle, and abnormal neuromodulation may be compressive lesions such as intracranial or orbital tumors, as well as neuroinflammation, congenital developmental abnormalities and other factors, which generally need to be treated for the cause, and there may be residual dysfunction after **. The ciliary muscle, the most important tissue in the eye, can change the convexity of the lens and adjust the focus of the eye to see near and far. Local inflammation, trauma, etc. can cause functional damage, the most common is senile degenerative changes, that is, presbyopia, the ability to regulate the ciliary muscle will gradually decline after the age of 40, and the ability to regulate after the age of 50 basically disappears, and reading glasses need to be worn to improve vision.
Hello: Dry eyes, blurred vision, this is a manifestation of dry eye syndrome, is a very common disease in ophthalmology, after this situation first go to the hospital for examination, such as dry eye related examinations, to understand the specific condition and severity. For mild dry eye syndrome, you can choose artificial tears to alleviate the symptoms, such as sodium hyaluronate eye drops, when buying eye drops, try to choose a type that does not contain preservatives, *** is relatively smaller, you can also choose the best contact lenses or wet room lenses, which can also relieve the symptoms of dry eye syndrome. >>>More
