The evolution of antibiotic therapy for bacterial conjunctivitis and keratitis: 1970-2000

The editors of this Festschrift asked us to review the use of antibiotics f or the treatment of bacterial conjunctivitis and keratitis over the past 25 years, a period coinciding with the life of the Castroviejo Corneal Societ y. We believe it is more appropriate to begin our review in the late 1960s, about the time that experimental and clinical studies and algorithms for t he clinical care derived From these studies helped shape a more rigorous ap proach to therapy. Those years saw the introduction of antibiotics that wer e adapted for ophthalmic use, many of which are still being used today. We will give more weight to our review of keratitis than conjunctivitis.
