Conjunctivitis in the neonate
This document is only valid for the day on which it is accessed. Please read our disclaimer.
2-12% of newborns develop conjunctivitis in the first 28 days of life.
- Conjunctival erythema
- Purulent discharge
- Lid oedema
Maternal history of:
- sexually transmitted diseases or exposure.
- results of high vaginal, cervical and urethral swabs in pregnancy
- Look for involvement of any other system, e.g. herpes vesicles, infected scalp pH site.
- In a well term baby take swab and consider saline drops alone while awaiting swab results. The most common cause of conjunctival discharge/sticky eye is naso lacrimal duct obstruction. Often self-limiting.
|Do this first unless Chlamydia is strongly
||Swab for MC & S (standard blue
Ask lab to process urgent gram stain for gonococcus if suspected. In working hours a special swab can be used to test for N.gonorrhea
|If Gram stain finds Gram -ve bacilli, seriously consider Pseudomonas and consider sepsis screen and parenteral anti-Pseudomonal antibiotics||PCP (BD probe tec swabs). Can also be used for Chlamydia (use small blue).|
|Tends to present between days 5-14.||Swab as above (Chlamydia PCR)|
|Viral Conjunctivitis, Adenovirus, Enterovirus and HSV|
|Green viral culture swab for HSV(processed 5 days/week).|
NB: Transport all specimens ASAP to Microbiology Laboratory, LabPlus.
- Nasolacrimal duct obstruction may cause 'sticky' eyes.
- Corneal abrasion following trauma at delivery.
- Glaucoma (watch for corneal clouding or proptosis, is associated with portwine stains in the ophthalmic region).
- Foreign body.
|Organism||Age of Onset||Clinical Features||Therapy|
|2-5 days||Unilateral, crusted purulent discharge||Topical Framycetin (soframycin) drops qds for 5 days|
|Neisseria gonorrhoeae #
Infants who are positive need to be evaluated for disseminated infections
|3 days to 3 weeks||Bilateral, hyperaemic, chemosis, copious thick white discharge||Ceftriaxone 50mg/kg IV/IM
as a single dose (maximum 125mg),
Saline irrigations hourly until exudate resolves
|Pseudomonas aeruginosa +||5-18 days||Oedema and erthyema of lid, purulent discharge.||IV anti-pseudomonal
|Chlamydia trachomatis *||5-14 days||Unilateral or bilateral, mild conjunctivitis, copious purulent discharge.||PO erythromycin
50mg/kg/day x 14d (qid)
Alternative, 5 days Azithromycin syrup
(= pertussis dosing 10mg/kg/day and 5mg/kg day 2-5)
|Herpes simplex||Conjunctivitis with
Need ophthalmology review within 24 hours.
|Acyclovir 30mg/kg/day IV
tid x 14-21d.
Topical acyclovir 3% 5 times daily.
# Uncommon, potential for serious consequences - severe keratitis and endophthalmitis. Requires early recognition and treatment. Needs blood and CSF culture. Consider concomitant chlamydial infection if poor response to cephalosporin. Parents require investigation and screening.
+ Risk of rapid progression from purulent discharge to denuding of corneal epithelium, and perforation of cornea. The anterior chamber can fill with fibrinous exudate, iris can adhere to cornea and later blood vessel invasion. The late ophthalmic complications can be followed by bacteraemia and septic foci.
* Most common pathogen, 20-50% of exposed infants will develop
chlamydia conjunctivitis, 10-20% will develop pneumonia. If relapse
occurs repeat course of erythromycin for further 14 days. Parents
NB: Chloramphenicol in topical therapy can obscure results of tests for chlamydia.
In cases of Chlamydia/N.gonorrhea, the LMC (midwife) needs to be informed.
