What researchers measure

Primary outcomes

  1. Percentage of Patients With Clearing (Clinical Success) of Conjunctival Erythema and Conjunctival Discharge at Day 7

    Percentage of patients that achieved clinical success, defined as a score of 0 for both conjunctival erythema and conjunctival discharge at Day 7. Conjunctival erythema and conjunctival discharge were each assessed on a 4-point severity grade scale (0=none, +1=mild, +2=moderate, +3=severe).

    Time frame: Day 7

Secondary outcomes

  1. Percentage of Patients With Microbiological Improvement

    Percentage of patients with microbiological improvement, defined such that all bacteria present above threshold at Day 1 (Baseline) are eradicated (absent) or reduced at Day 7 based on a Classification of Microbial Response (Eradication=pathogen is absent in follow-up culture; Reduction=pathogen is reduced from baseline below threshold count in follow-up culture; Persistence=pathogen reduced from baseline but is above or equal to threshold count in follow-up culture; and Proliferation=pathogen has increased in count from baseline in follow-up culture).

    Time frame: Day 7

  2. Percentage of Patients With Improvement in Ocular Signs for Lid Erythema

    Percentage of patients with at least a 1-grade improvement in ocular signs for lid erythema at Day 7 from Day 1 (Baseline). Lid erythema was assessed on a 4-point severity grade scale (0=none, +1=mild, +2=moderate, +3=severe).

    Time frame: Days 7

  3. Percentage of Patients With Improvement in Ocular Signs for Conjunctival Discharge at Day 7

    Percentage of patients with at least a 1-grade improvement in ocular signs for conjunctival discharge at Day 7 from Day 1 (Baseline). Conjunctival discharge was assessed on a 4-point severity grade scale (0=none, +1=mild, +2=moderate, +3=severe).

    Time frame: Day 7
