新生兒點眼藥水是怎麽回事

Eye infections used to be a major cause of blindness in children, and were often due to the same bacteria that cause gonorrhea or chlamydia in women. When a woman is infected with these bacteria (about 20 percent of women with gonorrhea and 70 percent of women with chlamydia don't have identifiable symptoms), they're present in her vagina. As a baby travels through the birth canal, s/he can pick up bacteria present in the mother's vaginal secretions or fluids.

Since eye infections with gonorrhea or chlamydia used to be such a common cause of blindness, many states now require antibiotic eye drops or ointments for newborns. Silver nitrate eye drops traditionally have been used to prevent eye infections. However, because these drops often cause the baby's eyes to be irritated, many hospitals now use erythromycin ointment instead.
