tobramycin gram (-)
Ophthalmia Neonatorum- Herpes simplex treatment
Ophthalmia Neonatorum- chemical silver nitrate treatment
Ophthalmia Neonatorum- marked by corneal opacities and possible micropannus
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
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.
inhibits bacterial protein synthesis, ung form used widely, excellent
choice for prophylactic treatment of ophthalmia neonatorum, oral use in C. trachomatis
interfere with DNA
synthesis, broad spectrum (99% of pathogens eradicated with 4th gen. FQ’s), very good drugs for initial treatment of bacterial conjunctivitis
Fluoroquinolones (nor-, cipro-, o-, moxi-, and gatifloxacin
aminoglycoside, inhibits bacterial protein synthesis, broad spectrum, risk of
contact dermatitis limits use
aminoglycoside, excellent gram (-) coverage, fair gram (+) coverage, can
cause corneal and conj toxicity.
aminoglycoside, very similar to gentamicin in efficacy, more potent
against P. aeruginosa, in combo with dexamethasone (Tobradex) is the most widely Rx’ed prescription in the U.S.
– inhibits the bacterial synthesis of folic acid, broad spectrum, resistance
and hypersensitivity are common, better options are available
