Outcome Measures
Primary Outcomes (1)
Ocular Itching Change From Baseline to Day 11
Ocular itching, as assessed by the participant, was measured on a 4-point scale 5 minutes after the conjunctival allergen challenge (CAC). 0 was best (no itching), and 4 was worst (worst itching).
5 minutes post-CAC
Secondary Outcomes (3)
Conjunctival Redness Change From Baseline to Day 11
7 Minutes post-CAC
Episcleral Redness Change From Baseline to Day 6
