The incidence of eye infection causing blindness following childbirth
is essentially zero precisely because of prophylaxis.  In 1880, 10% of
European children developed gonococcal conjunctivitis at birth, and
ophthalmia neonatorum was the leading cause of blindness.  The
following year, the use of silver nitrate reducted the incidence from
10% to 0.3%.  Currently, due to prenatal screening of mothers and the
use of prophylaxis, gonococcal ophthalmia has been passed by
chlamydial conjunctivitis in incidence.

I don't understand why you claim that gonococcal ophthalmia is no
longer a potentially blinding condition.  It still is.
