Visual Analog Scale (VAS) Global Ocular Discomfort Score, Area Under the Curve, Day 0 to Day 28 [ Time Frame: Up to 28 days ]
An electronic Visual Analog Scale (eVAS) was used by the subject to assess ocular discomfort, both frequency and severity, at Day 0 (pre-treatment) and daily thereafter for 28 days. Assessments were entered into a LogPad® (handheld electronic device). The VAS frequency score ranged from 0 (rarely) to 100 (all the time), and the VAS severity score ranged from 0 (very mildly uncomfortable) to 100 (very severely uncomfortable). The Global Ocular Discomfort Score is a composite of the frequency and severity VAS scores (0-100).
Discomfort based on global visual analog scale scores [ Time Frame: Up to 4 weeks ]

ESBA105 in Patients With Severe Dry Eye
Evaluation of ESBA105 in the Persistent Relief of Ocular Discomfort in Patients With Severe Dry Eye
The purpose of this study was to evaluate the efficacy of ESBA105 over vehicle in reducing the ocular symptoms of dry eye disease, as measured by a mean global Visual Analog Scale (VAS) discomfort score.
Following Run-In, patients qualifying for treatment were randomized 2:1 to receive ESBA105 (experimental group) or Vehicle (control group) for 4 weeks. Patients not qualifying for treatment (based on global VAS discomfort score), were discontinued from the study.
