Final answer:
To prevent gonoccocal ophthalmia neonatorum, antibacterial creams or drops are applied to infants' eyes after birth. Antibiotics are also used to treat any infections.
Step-by-step explanation:
To prevent gonoccocal ophthalmia neonatorum, it is common practice to apply antibacterial creams or drops, such as erythromycin, to infants' eyes shortly after birth. This is done to prevent the transmission of Neisseria gonorrhoeae, the bacterium that causes the infection, from the mother to the baby during childbirth. Antibiotics are also given orally or intravenously to treat any neonatal conjunctivitis that may occur.
