  2. Did you know.. • More than 8 million people are visually impaired or blind as a result of Trachoma. 2005 Statistics from International Trachoma Initiative www.trachoma.org

  3. Did you know.. • More than 8 million people are visually impaired or blind as a result of Trachoma. • Over 84 million have active disease. 2005 Statistics from International Trachoma Initiative www.trachoma.org

  4. Did you know.. • More than 8 million people are visually impaired or blind as a result of Trachoma. • Over 84 million have active disease. • It is completely treatable. 2005 Statistics from International Trachoma Initiative www.trachoma.org

  5. Did you know.. • More than 8 million people are visually impaired or blind as a result of Trachoma. • Over 84 million have active disease. • 75% of these are children • It is completely treatable. • WHO predicts that more than 150 million people are in need of treatment 2005 Statistics from International Trachoma Initiative www.trachoma.org

  6. So what is it? Defined as “a chronic, contagious infection of the conjunctiva and cornea, characterized by the formation of granulations and scarring, and caused by the bacterium Chlamydia trachomatis.”

  7. World Health Organization – Trachoma 2005

  8. A Look at the Bacteria…

  9. How it’s Spread The eye-seeking fly Musca sorbens aggressively feeds on ocular and nasal discharges And, these discharges may contain… Chlamydia trachomatis!

  10. How it’s Spread Person-to-Person: DIRECT contact with eye, throat, and nose secretions OR contact with inanimate objects that have had direct contact

  11. How it Affects the Body • Early symptoms similar to conjunctivitis (“pink eye”) and • This inflammation is called “active trachoma” and mostly seen in children

  12. Trachoma Symptoms.. • Also include structural changes: • Scarring in eye lid • Leads to distortion of lid • This leads to Trichiasis! (turned in eyelashes) • Blood vessels and scar tissue invades the upper cornea

  13. Trichiasis • Later stage of Trachoma • Eyelashes turn inwards and rub on the cornea

  14. Standard Antibiotic(As recommended by WHO) • Topical tetracycline ointment • Twice a day for 5 days • Once a month • For 6 months • OR • Azithromycin • Single oral dose

  15. How Azithromycin Works • Inhibits protein synthesis of the bacteria

  16. How Azithromycin Works • Inhibits protein synthesis of the bacteria Since it is a single oral dose for treating trachoma, DOT can be enforced

  17. WHO “SAFE”Approach • Lid Surgery • Antibiotics • Clean Faces • Environmental Changes

  18. 2020 Goal • 1998 WHO goal of eliminating trachoma by year 2020.

  19. 2020 Goal • 1998 WHO goal of eliminating trachoma by year 2020. • People affected fallen from 360 million in 1985 to ~80 million today
