Outcome Measures
Primary Outcomes (1)
Inflammation Change From Baseline to Day 6
Ocular inflammation was measured by a masked clinician on a 4-point scale 90 minutes after the conjunctival allergen challenge (CAC) . 0 = best (little to no inflammation), 4 = worst (most inflammation).
90 minutes post CAC
Secondary Outcomes (2)
Ocular Itching Change From Baseline to Day 6
7 minutes post-CAC
Ocular Redness Change From Baseline to Day 6
7 minutes post-CAC
