Gonococcal conjunctivitis. This is an eye infection that was caused by a gonococcal bacterium. Usually, this bacterium enters baby’s eyes during the passage through a birth canal in a woman who has untreated sexually transmitted infection (STD). baby develops yellow eye discharge on the first days after being born. Inclusion conjunctivitis. Chlamydia is the most common bacterial sexually transmitted infection worldwide. The estimated global incidence of chlamydial infection is approximately 131 million new cases annually. Although chlamydial infection typically affects sexually active adults, it can be passed on to newborns by their infected mother during delivery. Approximately 30% to 50% of infants born to a mother with active chlamydial infection will develop neonatal conjunctivitis, also known as ophthalmia neonatorum (ON). Infection in neonates commonly affects the conjunctivae, but it can occur also in the nasopharynx, lungs, vagina, urethra, and rectum. Neonatal conjunctivitis caused by Chlamydia trachomatis is an acute infection of the conjunctiva that is characterized by erythema and edema of the eyelids, palpebral conjunctivae, and purulent eye discharge. It typically occurs between 5 and 14 days after delivery, although it can present earlier.
Infection from other bacteria
Infection from other bacteria. Pus, swelling, and redness of the eyelids with redness of the conjunctiva are suggestive of infectious conjunctivitis. Discharge can be purulent in bacterial conjunctivitis and watery in viral etiology. Gonorrhea has profuse purulent discharge, Pseudomonas has greenish discharge, and chlamydia can be watery followed with purulent and bloody discharge. Conjunctivitis in both eyes is most often is seen with:
  • Staphylococcus aureus,
  • Pseudomonas aeruginosa,
  • Herpes simplex,
  • Adenovirus.
Bilateral conjunctivitis is seen with infection caused by N. gonorrhea or by use of ocular prophylaxis. Chlamydia usually develops in one eye but involves the other eye after 2 to 7 days if left untreated. Childhood conjunctivitis. This is also called neonatal conjunctivitis. Most of the problems are because of blocked tear duct that creates an abnormal accumulation of the mucus and tear in the eye. an infection may then enter the eye either during the birth or immediately after.
Childhood conjunctivitis
Risk factors include:
  • premature rupture of membranes,
  • prolonged delivery,
  • prematurity,
  • poor prenatal care,
  • maternal STI, HIV-infected mother
  • mechanical ventilation,
  • poor hygiene conditions.
Neonates at higher risk of congenital lacrimal duct obstruction include those with Down syndrome, Goldenhar Syndrome, clefting syndromes, midline facial anomalies, hemifacial microsomia, and craniosynostosis.
