Abstract
Trachoma is a chronic, epidemic and blinding eye disease, which is caused by Chlamydia trachomatis. Trachoma is endemic in over 50 countries. It is generally confined to poor populations.
Active infection with C. trachomatis is mostly seen in young children. While subsequent scarring and blindness is seen in adults, women have two to six times the rate of trachoma than men.
Trachoma is spread by direct contact with eye and nose secretion. Repeated episodes of infection from C. trachomatis lead to long term inflammation, scarring of the tarsal conjunctiva and distortion of the upper eyelid.
The Alliance for the Global Elimination of Trachoma by 2020 has adopted the SAFE (Surgery, Antibiotics, Facial cleanliness and Environmental improvement) as the main strategy against trachoma.
Trichiasis surgery reduces the risk of blindness by reversing the in turning of eyelashes and improve quality of live from non visual symptom.
A number of different antibiotics have antichlamydial activity and have been used for treatment of trachoma the most commonly used options are tetracycline eye ointment applied twice a day for six weeks or a single oral dose of azithromycin (20mg/kg up to a maximum dose).
Facial cleanliness and enviromental improvements components of the SAFE strategy are primarily targeting reduction the transmission of C. trachomatis between individuals.
Communities were randomized to one of the three arms insecticide spray, latrine provision and control removes faecal material from the environment to suppress the transmission of C. trachomatis and reduce the prevalence of active trachoma.
