How is keratoconjunctival xerosis caused?

summary

Xerophthalmia is often called dry eye. It is an inflammatory reaction in which the conjunctiva and cornea cannot be wetted. The cause of this disease is likely to be the lack of water or mucous components in the tears. The tear film rupture time of this disease is shortened, which can lead to filamentous keratitis, keratoconjunctivitis xerosis, and the reduction of tear at the edge of the eyelid. Severe patients can wear protective glasses or block the tears. Sometimes the eyes are too dry and the basic tears are insufficient, which stimulates the secretion of reflective tears and causes frequent tears. So, how is keratoconjunctivitis caused?

How is keratoconjunctival xerosis caused?

Often seen in the eyelid conjunctiva, it destroyed the conjunctiva itself secretory gland and even lacrimal gland, lacrimal duct caused. For example, severe trachoma, extensive thermal or chemical burns, severe chronic conjunctivitis, pemphigoid, etc.

2. It's caused by xerophthalmia arthritis syndrome. The cause of the disease is not clear. But it may be due to congenital immune system abnormalities. The main manifestations were keratoconjunctivitis xerostomia and connective tissue disease. We have to remember!

3. Xerosis of conjunctiva epithelium. This is mainly due to the lack of vitamin A. It is mainly caused by the large consumption of vitamin A in the body and the small intake. Most of them occur in infants with improper artificial feeding, when they have malabsorption or suffer from measles, diarrhea and other consumptive dysentery, it is easy to occur.
