There will be black spots in front of the patient's eyes, which will fly around with the rotation of the eyeball. Like floaters, the shapes are round, oval, dotted and linear. It is common that patients are more likely to find it when they look at bright backgrounds such as blue sky and white walls. Floaters mostly occur in middle-aged and elderly people over 40 years old, patients with high myopia and people who have undergone cataract surgery. Others, such as eye inflammation or retinopathy, can also form this disease. Most floaters are benign, or "physiological floaters", which is characterized in that if the patient has floaters in both eyes, it is impossible to determine which eye has floaters. If these phenomena do not worsen or change after a period of time, and the position of floaters is fixed, it is mostly benign. On the contrary, if the phenomenon of floaters suddenly appears and is limited to one eye, the direction of mosquitoes flying is uncertain, the dark shadow covers the field of vision, and the vision is poor and the field of vision is defective, all of which are ominous signs that must be paid attention to.
Dangerous symptom
Several dangerous symptoms of floaters are summarized as follows: (1) Abnormal flash. (2) Floaters increased in a short time. (3) the vision is blocked. Because a few floaters are signs of serious diseases, experts believe that if floaters are found dancing in groups in front of them, they should first have an expert examination. After the examination, if there are serious eye diseases, it is necessary to treat them. But the result of the inspection does not mean that there will never be a problem. Once there is a flash, floaters suddenly increase, or the line of sight is blocked, it is necessary to conduct a detailed inspection immediately. Floaters refer to small shadows fluttering in front of your eyes, especially when you look at a bright white background, which may be accompanied by a sense of flash. Vitreous liquefaction and posterior dislocation are the main causes of floaters. 70% of patients are caused by this, but14 patients may have diseases that threaten vision, among which retinal breaks are the main ones. When you see floaters, you should carefully check whether there is mydriasis in the fundus, including slit lamp three-sided mirror examination. Only those with posterior vitreous detachment do not need special treatment, and lesions harmful to vision are treated according to relevant principles. Floaters caused by eye inflammation feel that the black shadows in front of them are mostly dusty or flocculent, which may affect vision to varying degrees. Under the ophthalmoscope, there are dust and flocculent floating objects in the vitreous body, and the slit lamp three-sided mirror can show exudation caused by inflammation of the central choroid and white sheath of blood vessels. Floaters caused by intraocular hemorrhage feel that black shadows move like smoke clouds or flow like ink, and some have red or orange floating objects. Under the ophthalmoscope or slit lamp, we can see that there are flaky, flocculent and massive bleeding in the vitreous body with different thicknesses, and we can also see the primary retinal diseases that cause bleeding. Hemorrhage caused by posterior vitreous detachment from traction vessels is often accompanied by retinal breaks, which should be paid attention to. If it is floaters without pathological changes, it is recommended to see Chinese medicine, and the curative effect of Chinese medicine cannot be ignored. 、
Physiological floaters are called "good mosquitoes" and generally do not need treatment. As long as you have a proper rest, avoid fatigue, work and rest regularly, rest for 5 to 10 minutes every hour with your eyes for a long time, don't use the computer for too long, and stop using it if you feel uncomfortable. In addition, eating more iodine-containing seafood and foods containing vitamin C, such as vegetables and fruits, will also help. The main symptoms of physiological floaters are one or two shadows, flying around in front of our eyes, sometimes visible and sometimes invisible. When people are very tired, they will feel that mosquito movement is particularly obvious, while the elderly have floaters, which will be stronger and more obvious than middle-aged people. This kind of floater is benign and is called physiological floater. Experts believe that about 80% of floaters are formed by hydration of glass fiber and belong to physiological floaters. Physiological floaters have no risk of blindness (non-retinal problems). Usually, if there is no big problem, the doctor will advise not to pay attention to it until later in life.
Morbid floaters
Pathological floaters have three characteristics: ① abnormal flash. ② The number of floaters increased in a short time. 3. The line of sight is blocked. Pathological floaters are generally caused by serious diseases, which are caused by pathological changes of omentum, optic nerve, ciliary body and other structures near vitreous body. Suddenly, a large number of mosquitoes flew in, flashing a lot, and strange phenomena such as distorted vision, crooked straight line, distorted face, uncertain flying direction of mosquitoes, shadows covering the field of vision, poor vision, and visual field defect appeared. , are ominous signs that must be paid attention to, indicating that the vitreous body may be in acute degeneration, or the retina is in danger of perforation. It is necessary to see an ophthalmologist to check the retina as soon as possible. If diagnosed, surgery is often needed. Pathological floaters are also a manifestation of diseases, which are mostly caused by moderate and high myopia, intraocular hemorrhage and inflammation. Generally speaking, these causes can be found by simple examination and need to be treated according to the cause to recover. Physiological floaters can't find the cause and don't need special treatment. Clinically, floaters have some preferences for dialogue. Pathological floaters are mainly caused by lens and vitreous lesions. Lens opacity is called cataract. The lens opacity was a little flaky at first. There are some flaky shadows in front of me. Due to the high mass density of lens, the rotation direction of opaque point is the same as that of eyeball. That is, consistent with the direction of eye movement. Shadow tremor caused by turbidity in vitreous body is opposite to eye movement.
The disease of mosquitoes is vitreous opacity, and many people get this disease without timely treatment. And the usual nursing work is not done well. So what are the precautions for floaters? There are many precautions for floaters, and patients with vitreous opacity need to be treated cautiously and promptly, because many fundus diseases are caused by vitreous opacity. Then, let's take a look at the precautions for vitreous opacity. 1. Pay attention to rest and don't use your eyes too much to avoid myopia. Avoid "staring" and pay attention to frequent and complete blinking. Frequent blinking can reduce the exposure time of eyeball to air and avoid tears evaporation. 2. Don't blow the air conditioner for too long, avoid airflow blowing on the seat, and place tea leaves near the seat to increase the surrounding humidity. 3. Eat more fruits, especially citrus fruits, and eat more green vegetables, grains, fish and eggs. Drinking more water also helps to relieve dry eye. 4. Maintain good living habits, get enough sleep and don't stay up late. 5. Avoid operating the computer continuously for a long time, and pay attention to rest in the middle. Usually continuous operation 1 hour, rest for 5- 10 minutes. When resting, you can look at the distance or do eye exercises. 6. Maintain a good working posture. Keeping a proper posture and letting your eyes look down at the fluorescent screen can relax the neck muscles and minimize the area of the eyeball exposed to the air. 7. Adjust the distance position of the fluorescent screen. It is suggested that the distance is 50-70cm, and the fluorescent screen is slightly lower than the eye horizontal position of 10-20cm, showing a downward viewing angle of 15-20 degrees. Because angle and distance can reduce the demand for refraction and reduce the probability of eyeball fatigue. 8. If there are few tears and your eyes are easy to dry, it is not suitable to use contact lenses in front of the computer. Wear rimmed glasses. People who wear contact lenses in front of computers should also use varieties with high oxygen permeability. People over 9.40 years old, it is best to use bifocal lenses, or wear glasses with low degree when typing.
Therapeutic mode
Traditional therapy in China
Ancient Chinese Medicine Therapy (1) Computer people beware of floaters.
According to Hai Yin Jing Hui, this disease is caused by liver and kidney loss, so Bushen Pill should be used to treat it.

(2) physiotherapy ultrashort wave, ultrasound and iontophoresis of traditional Chinese medicine. Also, drugs such as Salvia Miltiorrhiza and Panax Notoginseng can be used for DC local iontophoresis. (3) Surgical treatment Vitrectomy is feasible for those who cannot be absorbed by traditional Chinese medicine and medical treatment. Vitrectomy should be performed if the vitreous hemorrhage is not absorbed after conservative treatment for 3-6 months. But once retinal detachment is observed, surgery should be done in time. In order to prevent amblyopia, children should be operated as soon as possible. Modern vitrectomy makes the treatment of some severe vitreous hemorrhage easier, safer and more effective. (4) Acupuncture Therapy The holographic acupuncture therapy of vibrating meridian system discovered by Mr. Peng provides a fast, effective, economical and simple treatment method for floaters. Acupoint selection: "Yan Ming 1", located between the second and third metacarpals, at the level of the valley.

Pathological floaters have symptoms such as flashing black spots in front of their eyes and fluttering mosquitoes, so they are named floaters. When opaque objects in the vitreous body are projected onto the retina, floaters will occur. Floaters are divided into physiological floaters and pathological floaters. Although the cause of physiological floaters is difficult to find, it does not need any drugs to treat physiological floaters, which may be caused by excessive eye use and long-term psychological depression. Therefore, patients with physiological floaters can increase their immunity as long as they pay more attention to eye health, do more outdoor sports and practice gymnastics. Pay attention to diet and drink more water containing natural minerals. It is also necessary to take rice as the staple food, eat more green food, and the vegetables are mainly cool. Eat some refreshing fruit. Your eyes can return to normal after relaxation. The etiology of pathological floaters is very complicated, which is caused by high myopia, intraocular bleeding caused by physical trauma or inflammation. Pathological floaters can explain the following: 1. Retinal tears and retinal detachment; Because of posterior vitreous detachment and other reasons, holes may appear in the retina, and liquefied glass will penetrate into the holes. The initial symptom is the sharp increase in the number of "floating objects" in front of us, which will lead to blindness if not controlled. 2, vitreous hemorrhage: diabetes, hypertension and trauma can all cause fundus hemorrhage, once the blood enters the vitreous, it will suddenly feel the symptoms of floaters or seem to open the red curtain. Because of bleeding and different parts, it will cause different degrees of vision decline. If there is less bleeding, it can heal itself. 3. Uveitis: Once bacteria or viruses enter the uvea, the eyes will become inflamed due to allergic reactions. At this time, white blood cells and exudate will enter the vitreous from blood vessels, resulting in the symptoms of floaters. When the inflammation gets worse, "plankton" increases and vision decreases. The above three floaters can be treated by taking lutein orally.
Nutritional diet therapy
Floaters are one of the most common complaints in eye clinics. Modern Chinese medicine ophthalmology has developed rapidly after absorbing foreign medical skills in surgical treatment, forming a pattern of paying equal attention to both medicine and surgical treatment. If you find the symptoms of floaters, you don't have to take them seriously, and you don't have to panic. Go to the hospital for eye treatment in time. If it is a physiological floating object, it has little effect on vision and does not need special treatment. It is worth noting that this degenerative symptom gradually appears in young people, which may be related to some modern people's irregular life and excessive use of their eyes and brains, and should be paid attention to. The most important thing is not to overwork, do more exercise, get enough sleep and get more sunshine. If it is a pathological floating object, it is necessary to find out the cause and treat it symptomatically, without any carelessness. The emergence of floaters not only brings inconvenience to life and work, but also causes dangerous and serious diseases such as retinal detachment or secondary glaucoma, especially those with high myopia, which should be prevented and treated in time. Nutritional prevention and treatment of floaters 1, should have enough vitamins. Vitamin A is an essential nutrient for eyes. Vitamin c and vitamin e can destroy free radicals, improve eye immune function and prevent vision loss; B vitamins can promote the metabolism of intraocular cells, which is very helpful for patients with eye diseases. Animals such as liver, eggs, dried beans, meat, mushrooms, fresh vegetables and fruits all contain a lot of vitamins, so eat more. 2. Eat more seafood, coarse grains and fish. These foods are very helpful to the eyes, because they contain minerals such as zinc and selenium, which can relieve eye fatigue and prevent vision loss. 3. Drink less caffeinated drinks, and it is best not to be contaminated with alcohol and tobacco, so as not to cause blurred vision and aggravate eye diseases. 4. Diet should be light and eat less spicy food. 5. Diet should be supplemented with recipes that can tonify liver and kidney, invigorate qi and nourish blood, which is very effective for myopia patients.
