Trachoma is a contagious bacterial infection which affects the conjunctival covering of the eye, the cornea, and the eyelids. Trachoma is caused by the Chlamydia trachomatis bacteria and is essentially totally preventable and curable. Infection causes inflammation, that is, a predominantly lymphocytic and monocytic infiltrate with plasma cells and macrophages in follicles. The follicles are typical germinal centers with islands of intense B-cell proliferation surrounded by seas of T cells. Recurrent conjunctival reinfection causes the prolonged inflammation that leads to conjunctival scarring.
In the Belgium, about 380 cases of Trachoma are reported in humans each year. Almost 10% of the Belgium population is infected with Trachoma an infectious disease caused by the bacterium Chlamydia trachomatis.Eyelid surgery to correct trichiasis is important in people with trichiasis, who are at high-risk for trachomatous visual impairment and blindness.
