Trachoma is a chronic infectious conjunctival keratitis caused by Chlamydia trachomatis. It is named trachoma because of its rough and uneven appearance on the conjunctival surface of the lid, which resembles sand grains. In the early stages of trachoma, there is infiltration of the conjunctiva, such as papillae and follicular hyperplasia, and corneal vascular opacification; in the late stages, scarring of the affected lid conjunctiva occurs, resulting in inversion of the eyelid, which aggravates the damage to the cornea and can seriously affect vision and even cause blindness.
