- Chlamydia is the most common cause of neonatal conjunctivitis but is also seen in young adults with a history of recurrent/chronic bilateral mucopurulent conjunctivitis.
- A sexual (general and specific STI) history should be investigated in all patients (mother in the case of neonatal conjunctivitis).
- The history is usually similar to that of acute bacterial infection but symptoms are much more severe and do not resolve quickly. There is more involvement of the cornea as well.
- A swab should be taken for culture and sensitivity if chlamydia is a suspected cause.
- A week of oxytetracycline eye drops in adults (erythromycin in used in neonates).
