Pharmaceutical composition for preventing and treating vitreous opacity

Abstract

The invention discloses a pharmaceutical composition for preventing and treating vitreous opacity and a preparation method of the pharmaceutical composition. The pharmaceutical composition provided by the invention is prepared by proportioning the following medicinal raw materials: herb of dicranopteris linearis underw, root of dalbergia hancei benth, cymene slice, polygalic acid and common anotis herb, and the pharmaceutical composition can be prepared into various dosage forms in accordance with a conventional preparation process. The pharmaceutical composition is significant in curative effect on preventing and treating the vitreous opacity.

Description

Technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, and in particular relates to a pharmaceutical composition for preventing and treating vitreous opacity and a preparation method thereof. Background technique [0002] The vitreous body itself has no blood vessels, and its metabolism is very slow. The vitreous body is mostly caused by the lesions of the surrounding tissues. Its pathological process is turbid, liquefied, and fibrous tissue is formed and contracted. Its classification is called inflammatory turbidity caused by inflammation, and turbidity caused by bleeding is called hemorrhagic Opacity, which is caused by degenerative changes, is called degenerative opacity. Inflammatory vitreous opacity is mostly caused by iridocyclitis, choroiditis (uveitis), retinitis and other pathological products such as inflammatory cells, exudates and necrotic tissues It is caused by entering the vitreous body. The opacity caused by iridocycl...

[0002] The vitreous body itself has no blood vessels, and its metabolism is very slow. The vitreous body is mostly caused by lesions in the surrounding tissues. The pathological process is turbidity, liquefaction, fibrous tissue formation and contraction. The classification is called inflammatory turbidity caused by inflammation, and hemorrhagic turbidity caused by bleeding. Opacity, caused by degenerative changes, is called degenerative turbidity. Inflammatory vitreous opacity is mostly caused by iridocyclitis, choroiditis (uveitis), retinitis and other inflammatory cells, exudates and pathological products such as necrotic tissue It is caused by entering the vitreous body. The opacity caused by iridocyclitis is mainly anterior; the opacity caused by retinitis and choroiditis is mainly posterior. Its shape can be dusty, silky, fluffy, lumpy or Cord-shaped, grayish-white dot-like or white flocculent, snowball-like turbidity, hemorrhagic vitreous opacity refers to visual impairment complications caused by ocular trauma or retinal vascular disease, when the amount of bleeding is large, it is equivalent to sudden blindness in traditional Chinese medicine , the red light reflection of the fundus disappears, the fundus cannot be seen, and the vision is light perception. Under the ophthalmoscope, there are cord-like and fast-like opacities in the vitreous body. Degenerative vitreous opacities are more common in the elderly with high myopia, and there are also young people with the disease. The higher the degree of myopia, the earlier the age of onset, and there are also changes such as degeneration, turbidity and liquefaction caused by inflammation and bleeding. In short, vitreous opacity is not a single disease. The etiology and pathogenesis are complex, and it is difficult to cure with western medicine
