Official Title: Confocal Analysis of Corneal Structures of Symptomatic Allergic Conjunctivitis Patients Pre and Post Treatment With Olopatadine HCL Ophthalmic Solution, 0.2%

Brief Summary: The purpose of this study is to descriptively evaluate the corneal structures of allergic conjunctivitis patients.

Detailed Summary: Heidelberg Retina Tomograph (HRT) will be used to descriptively evaluate the corneal structures and assess the immune cell status of allergic conjunctivitis patients pre- and post-treatment with olopatadine 0.2% in relation to a normative database.

Current Primary Outcome: Patient-Assessed Ocular Itching [ Time Frame: Baseline (Day 1), Day 14 ]

The patient rated the severity of ocular itching using a predetermined 0-4 scale, where 0=none and 4=severe itching with irresistible urge to rub. Each eye was rated separately. A 2-week washout period from prior allergy medication (if applicable) preceded the baseline assessment.


Original Primary Outcome:

  • Patient-Assessed Ocular Itching [ Time Frame: Day 1 ]
    As rated by the patient on a 0-4 scale.
  • Patient-Assessed Ocular Itching [ Time Frame: Day 14 ]
    As rated by the patient on a 0-4 scale.
