Brief Summary:
The purpose of this study is to evaluate the clinical and microbial efficacy and safety of AzaSite compared to tobramycin for bacterial conjunctivitis. Adults and children one year of age and older with bacterial conjunctivitis in at least one eye are eligible. Subjects will be randomly assigned to the AzaSite group or Tobramycin group. Three visits will be required for the study.

MedlinePlus related topics: Pink Eye

Arm Intervention/treatment
Experimental: AzaSite
1.0% azithromycin in DuraSite
Drug: AzaSite
AzaSite ophthalmic solution; one topical drop to the infected eye or eyes twice daily (in the morning and at bedtime) on Days 1 and 2 followed by once daily (in the morning between 7 and 10am) on Days 3 through 5.

Active Comparator: Tobramycin
0.3% tobramycin
Drug: Tobramycin
Tobramycin ophthalmic solution; one topical drop to the infected eye or eyes four times daily at 4 to 6 hour intervals (first dose in the morning between 7 and 10am) for 5 days.

Primary Outcome Measures :
  1. Number of Participants Who Achieved Clinical Resolution at Visit 3 [ Time Frame: Visit 3 (Day 6) ]
    Clinical resolution is defined as absence of all three clinical signs (ocular discharge, bulbar conjunctival injection, and palpebral conjunctival injection).

Secondary Outcome Measures :
  1. Number of Participants Who Achieved Bacterial Eradication at Visit 3 [ Time Frame: Visit 3 (Day 6) ]
    Bacterial eradication is defined as eradication of the causative pathogens as indicated by the absence of growth (0 colony forming units/mL) of the original infecting organism(s).
