How to prevent trachoma?

Trachoma is a chronic infectious disease of the conjunctiva and cornea. It is caused by Chlamydia trachomatis. Trachoma produces inflammation and scarring of the conjunctiva. This leads to inward deviation of eyelashes and lid margin. The eyelashes produce abrasion of the cornea which results in corneal ulcer. Ultimately it leads to blindness.
