What is meibomian gland dysfunction?

The occurrence of meibomian gland dysfunction is related to congenital abnormalities, systemic diseases, chronic blepharitis and other reasons, analysis is as follows:

1, congenital abnormalities

If the patient has congenital meibomian gland vesicles, ducts, openings abnormal, or Turner syndrome, cleft lip and palate and other congenital abnormalities, will lead to congenital meibomian gland secretion decreased, resulting in meibomian gland dysfunction.

2, systemic diseases

If the patient has Sjogren's syndrome, rosacea, dyslipidemia and other systemic diseases, will affect the meibomian gland secretion capacity, resulting in meibomian gland dysfunction.

3, chronic blepharitis

If the patient has chronic blepharitis, will lead to phosphatidyl ethylamine alcohol, sphingomyelin abnormalities, easy to induce meibomian gland dysfunction.
