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. |
- 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).
- 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).
