Ophthalmia Neonatorum- marked by corneal opacities and possible micropannus
Chlamydial
Bacitracin
inhibits bacterial cell wall synthesis, good gram (+) coverage, poor gram (-)
coverage (except Neisseria
changes permeability of the bacterial cell membranes causing cell death,
fair gram (+) coverage, poor gram (-) coverage (except H. influenzae
Gramicidin
changes permeability of the bacterial cell membranes causing cell death,
no gram (+) coverage, fair gram (-) coverage (good against P. aeruginosa), very important in CL wear, excellent when combined with an effective gram (+) agent.
Polymyxin B
prevents the conversion of dihydrofolic acid preventing cell growth,
broad spectrum (does not cover P. aeruginosa), excellent choice when combined with Polymyxin B.
Trimethoprim
inhibits bacterial protein synthesis, ung form used widely, excellent
choice for prophylactic treatment of ophthalmia neonatorum, oral use in C. trachomatis
Erythromycin
interfere with DNA
synthesis, broad spectrum (99% of pathogens eradicated with 4th gen. FQ’s), very good drugs for initial treatment of bacterial conjunctivitis
