Clinical Trial Outcome Measures

Primary Measures

  • Sign and symptoms composite score
    • Time Frame: 10 days
    • The change from baseline in the signs and symptoms score. Global sign and symptom score defined as the total score of lid margin redness (0-3), lid swelling (0-4), bulbar conjunctival redness (0-3), palpebral conjunctival redness (0-3), ocular discharge (0-3), itchy eyelids (0-4), and gritty eyes (0-4). The change from baseline to Day 10 (Visit 3 at day 1, day 7 and day 10) in the ocular signs and symptoms composite score. Ocular signs and symptoms were collected for study eyes at each study visit using a 0-4 grading scale, assessed as 0 = none, 1 = minimal/trace, 2 = mild, 3 = moderate, and 4 = severe. The signs and symptoms composite score was the sum of each individual sign or symptom score.
