Conjunctival cover repair

The conjunctiva is a layer of mucous membrane covering the upper and lower eyelids and in front of the eyeballs. It is a transparent film formed by stratified columnar epithelium and a small amount of connective tissue. The lining of the eyelid is the palpebral conjunctiva, and the bulbar conjunctiva is stuck in front of the eyeball. The conjunctiva is rich in blood vessels and nerve endings, and has a small number of mucous glands, which can secrete mucus and smoothen the eyeballs to reduce friction between the conjunctiva and the cornea. Chlamydia trachomatis mainly invades the conjunctiva and fornix conjunctiva. Acute bacterial conjunctivitis and viral conjunctivitis are caused by bacteria and viruses that infect the conjunctiva and are both contagious.
