Allergic Conjunctivitis
Conditions
Brief summary
The study was designed to evaluate the pattern of seasonal allergic signs and symptoms consistent with ongoing ocular allergic inflammation during ragweed season. It was hypothesized that a pattern of ongoing ocular allergic inflammation existed in certain subjects.
Detailed description
Subjects who had a positive skin test to ragweed within 24 months of Visit 1 were instructed to complete a diary, which assessed their allergic signs and symptoms 3 times a day for 4 weeks. During the in-office visits, subjects were asked to completed a quality of life questionnaire, as well as a retrospective and/or prospective eye allergy questionnaire.
