In 1881, Credé introduced the ocular instillation of silver-nitrate solution in the newborn, after the birth, for the prophylaxis of gonococcal ophthalmia neonatorum. Although the Credé Method has been used for almost one hundred years, there is controversy among authors about the indications, the way of application and the replacement of anti-bacterial agent. The studies about gonococcal ophthalmia neonatorum and gonorrhea in pregnant women were all made in hospitals; no national statistics are available. The problems of failure and risk of Credé Method is attributed to the improper application of silver-nitrate solution. The author suggests continuation of tlie routine of Credé Method in all newborns.
