Figure 131.6 Group B streptococcus colonies cultured on blood agar.  NEONATAL CONJUNCTIVITIS osms.it/neonatal-conjunctivitis PATHOLOGY & CAUSES ▪ Clinical infection manifestation occurs within ﬁrst four weeks of life, AKA ophthalmia neonatorum ▫ Most commonly caused by Neisseria gonorrhoeae/Chlamydia trachomatis (coinfection with both microbes common) ▫ Rarely, herpetic conjunctivitis caused by herpes simplex virus (HSV) ▫ Staphylococcus, Streptococcus may also be implicated in some conjunctival infections  COMPLICATIONS ▪ ▪ ▪ ▪  Corneal ulceration, scarring Vision impairment, blindness Systemic sequelae of infection HSV: keratitis, keratouveitis  SIGNS & SYMPTOMS ▪ Eyelid swelling, watery/mucopurulent discharge, chemosis, micropannus (granulation tissue membrane)  Transmission ▪ Primarily via exposure to mother’s infected genital ﬂora during vaginal birth ▪ Ascending infection in case of premature membrane rupture  RISK FACTORS  ▪ Maternal infection Figure 131.7 The clinical appearance of severe neonatal conjunctivitis.  822 OSMOSIS.ORG
