AI Technical Summary

Problems solved by technology

There are various causes of dry eye, and the pathogenesis has not been fully clarified. The treatment of dry eye is still in the stage of symptomatic treatment, and it is difficult to cure it.

At present, the most commonly used method to treat dry eye is local application of artificial tears to moisten the cornea and conjunctiva, increase the viscosity of tears, slow down its evaporation or drainage, etc., but the improvement effect on dry eye symptoms is very limited

Moreover, at present, many artificial tears contain preservatives. Although the content is very low, long-term use can lead to iatrogenic aggravation of ocular surface diseases; even artificial tears without preservatives also have disadvantages. Sexuality declines as patients have to carry it with them for 24-hour use

Moreover, many artificial tears need to be refrigerated, which is inconvenient to store

Although the lacrimal canalicular embolization is less painful and easy to operate, the disadvantages are that the occluder may cause irritation, the occluder is lost or slipped into the lacrimal duct, epiphora occurs after the punctum is closed, and irreversible damage after permanent occlusion

Submandibular gland transplantation has become a relatively mature surgical method for the treatment of dry eye in ophthalmology in recent years. Difficult to popularize

However, the current research on the treatment of dry eye in traditional Chinese medicine has the following problems: (1) The current research on the treatment of dry eye in traditional Chinese medicine is still mainly focused on summarizing the laws of syndrome differentiation and observing the curative effect of traditional Chinese medicine, lacking in theory, method, prescription, and medicine. systematic research

(2) Lack of unified curative effect evaluation standards, especially the curative effect judgment standards of traditional Chinese medicine itself, making it difficult to objectively evaluate curative effect

(3) At present, most clinical observations lack rigorous design, stay at the level of experience summarization, lack long-term follow-up observations with large samples, some clinical studies lack control groups, and observation indicators are mostly measured by subjective indicators such as improvement of clinical symptoms. Insufficient observation of long-term efficacy makes the research results lack strong convincing
