Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Ocular Surface Disease Index (OSDI) at Week 2
Time Frame: Baseline, Week 2
|
Change from baseline in OSDI at Week 2. The OSDI consists of 12 questions measuring the presence of ocular symptoms.
Each of the 12 questions is assessed using a 5-point scale (0=none of the time; 4=all of the time).
The score is converted to a 0-100 score where 0 is best and 100 is worst.
Higher OSDI scores are associated with greater severity.
A negative number change from baseline indicates improvement.

Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Tear Breakup Time (TBUT) at Week 2
Time Frame: Baseline, Week 2
|
Change from baseline in TBUT at Week 2. TBUT is defined as the time required for dry spots to appear on the surface of the eye after blinking.
The longer it takes, the more stable the tear film.
A positive number change from baseline indicates improvement.
|
Baseline, Week 2
|
|
Change From Baseline in Corneal Staining at Week 2
Time Frame: Baseline, Week 2
|
Change from baseline in corneal staining at Week 2. Staining of the cornea following ocular administration of fluorescein dye was graded using a 6-point scale (0=no staining, 5=diffuse staining).
The higher the grade score, the worse the dry eye severity.
A negative number change from baseline indicates improvement.
|
Baseline, Week 2
|
|
Change From Baseline in Conjunctival Staining (Temporal) at Week 2
Time Frame: Baseline, Week 2
|
Change from baseline in conjunctival (temporal) staining at Week 2. Staining of the conjunctiva following ocular administration of lissamine green dye was graded using a 6-point scale (0=no staining, 5=diffuse staining).
The higher the grade score, the worse the dry eye severity.
A negative number change from baseline indicates improvement.
|
Baseline, Week 2
|
|
Change From Baseline in Conjunctival Staining (Nasal) at Week 2
Time Frame: Baseline, Week 2
|
Change from baseline in conjunctival staining (nasal) at Week 2. Staining of the conjunctiva following ocular administration of lissamine green dye was graded using a 6-point scale (0=no staining, 5=diffuse staining).
The higher the grade score, the worse the dry eye severity.
A negative number change from baseline indicates improvement.
