The traditional Chinese medicine composition disclosed by the invention is a pure traditional Chinese medicine external preparation, has the advantages of no toxic or side effect and quick effect taking, and can be absorbed easily; and the traditional Chinese medicinecomposition can prlong the tear break-up time, increase the tear flow, improve conjunctivitis, effectively relieve the symptoms of xerophthalmia, and the like, thereby performing the functions of xerophthalmia treatment and eye health care.

Description

technical field [0001] The invention relates to a pharmaceutical composition and a preparation method thereof, in particular to a traditional Chinese medicine composition for externally treating dry eye and a preparation method thereof. Background technique [0002] With the development of society and the acceleration of the pace of life, occupational diseases represented by dry eye have become common, frequently-occurring and refractory diseases in ophthalmology. According to the survey, 13.3% of them are aged 43-84 in the United States, 17.0% in Japan, 28.7% in Canada, and 10.3% in Australia. Dry eye has many etiologies and complicated pathological process. It is a common ocular surface disease in ophthalmology clinic. The tear secretion of patients is significantly reduced or the tear composition is abnormal, the tear film breakup time is shortened, the corneal epithelium is punctate, and the fluorescein staining is positive. Since the tear film can no longer assume its ...

Problems solved by technology

However, as a general inflammatory treatment during treatment, the patient’s symptoms have not completely disappeared or improved, or even aggravated, which will lead to serious ocular surface diseases, including complications such as corneal surface abrasion, filamentous keratitis and corneal ulcer, and eventually lead to corneal opacity and serious consequences of vision loss

[0004] At present, the measures to prevent and treat dry eye are relatively limited. Mild cases can relieve symptoms by dripping "artificial tears" for a long time, but preservatives can damage the tear film; moderate cases can wear silicone eye masks, wet room mirrors, diving goggles, and therapeutic corneas. Contact lenses or implantation of punctum plugs to maintain the retention of tears in the eye; in severe cases, eyelid suture is performed to prevent the occurrence of complications such as corneal degeneration

In short, although there are many treatment methods, there are also many disadvantages, and the curative effect is not sure, and it cannot fundamentally improve the quality and quantity of the patient's own tears.
