V. Signs
- May present as subacute case (>4 weeks)
- Unilateral Conjunctivitis with hyperemia and mucopurulent discharge (stringy mucous discharge)

- Tiny, rice grain size, gelatinous pale bumps on the Conjunctiva at fornix
VI. Causes
- Chlamydia trachomatis
- Less common Chlamydia Conjunctivitis causes
VII. Differential Diagnosis
VIII. Management
- Trachoma
- Azithromycin 20 mg/kg orally (up to 1 gram) for single dose (or Doxycycline 100 mg orally bid x21 days) AND
- Topical Tetracycline or Erythromycin ointment twice daily for 28 days
- Adult Inclusion Conjunctivitis (AIC)
- Azithromycin 1 g for 1 dose (or Doxycycline 100 mg twice daily for 7 days) AND
- Topical Erythromycin ointment to eye twice daily for 21 days
- Neonatal Inclusion Conjunctivitis (NIC)
- Erythromycin base or EES 50 mg/kg/day divided four times daily for 14 days
IX. Prevention
-
Erythromycin or Tetracycline ophthalmic ointment
- Applied to newborns eyes within 1 hour of delivery
- Sexually Transmitted Disease Prevention
- Sexually Transmitted Disease surveillance in Pregnancy

| Definition (MSHCZE) | Zánět spojivek (konjunktivitida) charakterizovaný nálezem inkluzí (tzv. iniciálních tělísek) ve stěrech ze spojivky. Bývá způsoben chlamydiemi. Projevuje se hnisavou sekrecí. Vyskytuje se u novorozenců (inkluzní blenorea) nebo dospělých (tzv. konjunktivitida z plaveckého bazénu). Léčí se antibiotiky, dospělým lze podávat tetracyklin, novorozencům např. erythromycin. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ ) |
| Definition (MSH) | An infection of the eyes characterized by the presence in conjunctival epithelial cells of inclusion bodies indistinguishable from those of trachoma. It is acquired by infants during birth and by adults from swimming pools. The etiological agent is CHLAMYDIA TRACHOMATIS whose natural habitat appears to be the genito-urinary tract. Inclusion conjunctivitis is a less severe disease than trachoma and usually clears up spontaneously. |
