How to Treat Xerophthalmia
Most people with xerophthalmia have missing meibum, it will cause tear film to disappear, cornea hypoxia, lack of nutrients and normal delivery of metabolites, and corneal epithelial cells, elastic layer cells, stromal layer cells will fall off, resulting in corneal sicca, keratitis, blepharitis and other symptoms. In the direction of treatment, It can be considered to reconstruct the tear film of the human eye and restore the normal metabolic cycle of the human eye to achieve the purpose of treatment.
Artificial tears are currently the mainstream medicine for the treatment of xerophthalmia.
However, although called "artificial tears", these products do not have the biologically active ingredients present in natural tears, such as the proteins, lysozyme, and immunoglobulin A that are rich in natural tears. Most of them just act as lubricants to realize the effect of alleviating the symptoms of patients. Artificial tears can improve the stability of the tear film, improve the contrast sensitivity and the optical quality of the ocular surface. That is to say: artificial tears can relieve the symptoms of xerophthalmia, but can not completely remove the symptoms of xerophthalmia, just reduce the discomfort of patients by one level.
The two drugs listed in the United States, Restasis and Xiidra, are mainly used to reduce inflammation, increase tear secretion, and repair corneal epithelial cells in a small amount. At present, clinical feedback still has discomfort after using. In theory, it does not continue to deliver nutrients to the cornea and take waste, the condition has not improved after long-term use.
In the United States, there are also some new concept brands for the treatment of xerophthalmia, such as Biotech (BIO) meibum oil. This new brand technology subverts the traditional treatment from tears and cornea. It start with meibum to achieve the triple synergy of artificial meibum + artificial tears + tear film. This is a technology that has been developed by professors of Harvard Medical School for more than ten years, extracted from thousands of plantations that overlap with artificial meibum. It is relatively advanced; it is said that the clinical effect in the United States is very good.
In mild patients, you can rest and relax more, and cooperate with diet to recover.
