    Vitreous opacity shows signs of self-shrinking to a certain extent, and in a very small number of patients with mild symptoms of physiological and degenerative floaters, it disappears spontaneously or shrinks to a less noticeable extent.

    Pathological floaters usually do not go away on their own and require prompt and effective remission**, but there is usually a tendency to resolve spontaneously in very small amounts of vitreous and preretinal hemorrhages or very mild vitreous or retinal inflammation. In general, if symptoms appear, it is recommended to go to a specialist hospital for examination.

    Some mild vitreous opacities absorb on their own.

    The material of glass is made up of three main parts: the basic raw material, the flux and the colorant, as well as the decolorizer, the clarifier and the emulsion.

    The basic raw material for glass making.

    Silica is the most important raw material for glass production. The reserves of silica on the earth are very large. Silica is the main raw material for stone and the main raw material for making glass.

    The silicon content of different stones is different. These materials are the most common in our lives.

    flux. The melting point of silica is very high, and it is very limited to achieve this honor. The ancients tried to add some other substances, and when it melted, the temperature became lower.

    In addition, the silica melts very abruptly, and there is no filter transition stage that gradually softens during the heating process, and after fusing some other substances, the glass can be in various glorious states at different temperatures, and the glass can be effectively shaped and shaped. This substance is the flux.

    The flux is usually a raw material containing sodium oxide, potassium oxide, lead oxide, calcium oxide, barium oxide and other substances, such as limestone, feldspar, soda ash, boric acid, lead compounds, and barium compounds. (Sodium oxide can reduce the viscosity in the formation of glass, make the glass easy to melt, and play a good role in fluxing; Barium oxide plays a fundamental role with sodium oxide in the formation of glass; Tin oxide can increase the chemical stability and mechanical strength of glass; Lead oxide can increase density, improve serpentine, and have a special luster; Lead can make the glass have a large refractive index to light and a small scattering rate, making the glass more shiny and stable.

    Clarifier. Some bubbles will appear in the process of making glass, and the clarifier used to reduce these bubbles is used. The main commonly used are arsenic oxide, antimony oxide and nitrate.

    Emulsion. In the production of glass, the artist makes the glass opaque according to the requirements of the work, and the emulsion is the emulsion that makes the glass opaque. It can cause glass to produce crystalline or unfixed colloidal particles that differ from the refractive index of the glass itself to produce an opaque effect.

    Commonly used emulsions are tin oxide, antimony oxide, and phosphate.

    Decolorizing agent. The head colorant is mainly used to eliminate the undesirable color brought by the impurities in the raw materials to the glass, so that the glass city is colorless and transparent. There are two main types of chemical decolorizing agents and physical decolorizing agents, and chemical decolorizing agents usually disappear through oxidation, mainly sodium nitrate and potassium nitrate.

    Physical decolorizers make glass colorless by producing complementary colors, mainly manganese dioxide, selenium and cobalt oxide, and bromine oxide.

    Simple vitreous opacity, commonly known as "floaters" is generally caused by vitreous liquefaction or vitreous detachment, you can do an eye B ultrasound to check the specific situation of the current turbidity, as far as the current medical level is concerned, **vitreous opacity caused by floaters there is no very effective drug and particularly good method, mild vitreous opacity as long as it does not affect vision, don't care about it, Chinese medicine recommends taking Chinese medicine decoction to assist**, but the effect should vary from person to person, and the general effect is not great. It is recommended to inject iodine directly to promote cloudy absorption, but I personally think that this method is not only painful but also has little effect, and I usually eat more iodine-containing foods.

    Vitreous opacity is a common ophthalmic disease, as long as it is not particularly cloudy, it does not affect normal life, and it is not a big problem, and patients with high myopia are more likely to have it. In general, floaters do not cause blindness. If there is severe vitreous opacity that interferes with daily life, vitrectomy may be used for surgery**.

    Personally, I think home remedies are useless, this is a problem in the vitreous, the vitreous itself is not strong in absorption and metabolism, it can be absorbed less by oral drugs, and the liquefied part is less likely to recover, it is generally not very good, and the effect of traditional Chinese medicine is not very good, don't make so many useless home remedies to make trouble for yourself, pay attention to eye hygiene, and regular re-examination is true.

    Hello, vitreous opacity is mainly caused by retinal or ciliary hemorrhage.

    Guidance: There is no specific drug for vitreous opacity, you can now use some iodine intramuscine injection, generally a course of treatment for ten days, and then use some salvia, Chuanxiongzine injection and other drugs to promote blood circulation and remove blood stasis**, which may have a certain effect, if it affects vision, you can do vitrectomy.

It is recommended to go to the hospital for eye examination, and then do the ** plan according to the condition. Patients with fresh vitreous hemorrhage should be given bed rest and hemostatic drugs; For patients with old bleeding, drugs that promote turbid absorption should be used, such as lutein with liquid lutein, oral vitamin C, dibazole, etc., and intramuscular injection of iodine or hyaluronidase. In severe cases, vitrectomy may be used if it is generally ineffective. >>>More

Vitreous opacity in the elderly can be topical eye drops aminopeptide eye drops, aminoiodopeptide eye drops, horse cuff digitalis diglycoside eye drops, intramuscular aminoiodopeptide injection for 10-14 days for a course of treatment, and oral lecithin complex iodine, all of which have certain curative effects. There are no blood vessels in the vitreous, so the vitreous is cloudy and absorbs slowly. In addition, senile vitreous opacity, like graying of hair in old age, is a degenerative change. >>>More

The recovery period of surgery is about 6 months to 1 year, during which you should pay attention to medication and eye hygiene, and whether your vision will deteriorate depends on what you said. If it is close to the eye, it will definitely have an impact, because the intraocular lens does not have the function of telescoping, and it cannot be adjusted when looking close, so it is not a big problem to see far.

When the eye is myopia, especially high myopia (above 500 degrees), the eyeball will undergo elongation and deformation of the anterior and posterior diameters, squeezing the vitreous fiber scaffold, and the vitreous fiber scaffold will accelerate its collapse after being squeezed. As we age, the cumulative effect of light will also accelerate the collapse of the glass fiber scaffold. >>>More
