A Study to Assess Alcon's Ocular Image Quantification Using Conjunctival Allergan Provocation Testing (CAPT) and Natural Allergen Exposure in an Environmental Exposure Chamber (EEC)
The purpose of this study was to evaluate ocular responses with different allergen provocation methods.
Subjects demonstrating a successful allergen response to a common allergen received the first study treatment and used as instructed for 5 days, after which they entered the Environmental Exposure Chamber (EEC) for a 3-hour exposure to a known concentration of the allergen. After waiting at least 7 days, subjects received the second study treatment and used as instructed for 5 days, after which a 3-hour Conjunctival Allergen Provocation Test (CAPT) was performed with an escalating concentration of the allergen. Subjects dosed with study treatment approximately 15 minutes prior to each allergen provocation test.
