Trahom (Trachoma) je specifični zarazni keratokonjunktivitis prouzrokovan serotipovima A, B, Ba i C Chlamydia trachomatis. Trahom predstavlja najčešći uzrok preventibilnog slepila u svetu pored katarakte i glaukoma. Oko 84 miliona ljudi ima aktivni trahom, 7,6 miliona ljudi sa neoperisanom i netretiranom trihijazom trpi posledice trahoma a 1,3 miliona ljudi je slepo. Danas je prihvaćena klasifikacija Svetske zdravstvene organizacije (SZO) koja koristi gradiranje na osnovu prisustva ili odsutva 5 kliničkih znakova. SZO ima program za eradikaciju slepila u svetu do 2020. godine koji se zove "Pravo na vid". U okviru tog programa nalazi se i program za eradikaciju trahoma u svetu, takozvana SAFE strategija. Ona podrazumeva hiruršku korekciju komplikacija kod trahoma (S-surgery), primenu antibiotika (A-antibiotic), higijenu lica (F-face) i rad na poboljšanju socijalno-ekonomskih i higijenskih uslova života (E-education). Lečenje trahoma sprovodi se lokalnom i sistemskom primenom odgovarajućih antibiotika. Komplikacije trahoma kao što je trihijaza rešavaju se hirurškom korekcijom i na taj način sprečavaju pojavu kornealnih zamućenja i dodatni gubitak vida. SUMMARYITrachoma is keratoconjunctivitis caused by ocular infection with Chlamydia trachomatis. Endemic trachoma is caused by serovars A, B, Ba and C. Trachoma is probably the third most common cause of blindness worldwide, after cataracta and glaucoma. Active trachoma affects an estimated 84 million people; another 7.6 million have end-stage disease, of which about 1.3 million are blind. Most trachoma programmes use the WHO simplified grading system, by presence or absence of five clinical signs. The World Health Organization is leading a global effort to eliminate blinding trachoma by the year 2020, through the implementation of the SAFE strategy. This involves surgery for trichiasis (S-surgery), antibiotics for infection (A-antibiotic), facial cleanliness (F-face) and environmental improvements to reduce transmission of the organism (Eeducation). Tratment for trachoma includes local and systemic administration of appropriate antibiotics. Surgical correction of trachomatous trichiasis reduces the risk of progressive corneal opacification and blindness.
